[Q] WiFi AP priority when many in range - Galaxy S III Q&A, (US Carriers)

I realize this question will probably go unanswered, and I've searched, but I'll ask anyway:
Does anyone know if any ROM has an option to prefer connecting to one WiFi AP over another when BOTH (or two or more) are in range? The current algorithm seems to prefer whichever has the stronger signal at the time of (re)connection.
i.e.: I have a dual-band Netgear WNDR3700 router that has both 802.11G and 802.11N radios. Obviously I'd like to give N higher priority since it's got more bandwidth, but I can't, and I often discover that my phone is still connected to the slower G when I want N. I know that I could tell my phone to "forget" about my wireless G AP, but, wireless G gets much better range than N, so I like it when it hops over to G when I get out of range N, and then hops over to 4G when I'm out of range of both.

The hack-ish solution might be to get some NFC tags set up to connect to specific networks spaced at locations around your location where you know you typically leave range of either of the routers.

Wireless N???

The phone says its wireless N able but I can't seem to get it to see my wireless N network over 5GHz. It sees my wireless G network over 2.4GHz fine but not wireless N over 5GHz evidently.
Anyone gotten theirs to connect to N networks? If so what were your configs for channel, and all that if you mind me asking?
I haven't had any issue connecting to wireless n. I'm connected at home, girlfriends and work. My router is channel 11, gf is channel 6. I don't know about work.

If your on channel 11 then your only on 2.5GHz not 5GHz. do me a favor and while your connected on your Evo3D go into wireless settings and click on the network that your connected to and tell me the speed it shows. Willing to bet its only 65Mbps, which is because your on 2.5GHz and not 5GHz.

There is a difference between A/N and B/N.
B/N is 150Mbs + and has better penetration than A/N. You're asking the wrong question.
Yes, you can connect to a B/G/N network. No you cannot connect to a 5.0GHz anything network.

So this has a single antennae then correct just like the Evo4G did which is why it couldn't connect to 5.0GHz networks?
j/w b/c I can't get past 65Mbps on the connection while I thought the 3D had a better wireless card in it than the 4G. Its not my router as I get boost up to 130Mbps on my laptop connected to same SSID at times.
Just a bummer thought we were getting a true wireless N capable phone.
This makes me wonder even more why they took out N capability in the Evo4G update and never added N to the spec sheet.
A single antenna is not what makes it 2.4GHz vs 5GHz. The single antenna basically limits it to Wireless N, 150Mbps vs 300Mbps. The 5GHz is just the frequency that it travels over, and most mobile devices won't do 5Ghz, and will only have a single antenna.

So your able to connect over 2.4GHz freq and your evo3d shows its connected at 150Mbps??
I have a top of line netgear full dual band router here so I know its not that, esp seeing as my pc connects at 150Mbps over the 2.4GHz band. I'm checking this by just clicking on the SSID after connected on the Evo3D, or checking Status on my PC's connection.
Dont get why I'm always showing 65Mbps on the Evo3D. Would of thought that since they are publishing that they support Wireless N as opposed to the Evo4G who only had 1 antennae, that I would connect at higher speed than the Evo4G. did

There's nothing more misleading than the whole "link speed". I've never seen an actual 150Mbs off of my A/N "300Mbs" connection, and that's with the laptop sitting 4ft from the router. The phone can't utilize anywhere near that bandwidth, and I'm willing to bet that even if your internet is several MB/s, you won't actually find a website to give you more than 1.2MB/s. Microsoft is one of the few that I know of that can really dish the data out.....but how often are you downloading massive updates?

Not concerned with internet speed and more so looking at my internal network speeds for file transfers and such.
I get that it can be missleading but do not get that if the Evo4G which has a less powerful card than the 3D evidently that the 4G and 3D show the same link speeds.
I prob need to check the specs on each phones card really though the more i think about it b/c most i have been going off of is word of mouth like the 4G only having 1 antennae and such. No clue if the 3D has 2 or not.

You'll probably find that the WiFi and BlueTooth antenna are shared....and if a phone has an FM rx, it too will use that antenna. Not likely to find a cellular with dual WLAN antennas.....they're not really built to be a dedicated WIFI anything.
If you're concerned about xfer rates on the phone, yank the SD card out and put it in a reader. That's the fastest way to get data to the phone, followed by hooking up the phone via USB. The phone has no use for WLAN data rates above 15Mb/s. If you're transferring movie files, use the USB connection method. Outside of that, don't sweat it. I honestly couldn't see someone moving GBs worth of data on a constant basis with the phone.....and if you are, sounds like you should look at something with larger storage like a Tablet PC.

I hear ya im aware of outside options. I just thought that since this phone is supporting wireless N fully then the link speeds would be able to be higher than the link speed on the 4G.
But again like i said before i really need to get down to it and look at the documentation of the chips used on the 4G and 3D to see what differences there are.
EDIT:
NVM makes sense now. both phones have the same Broadcom chip inside. the Broadcom BCM4329.
BUT whats odd is that from what i read that chip only supports bluetooth 2.1 while we supposedly have 3.0 on this phone. Also interesting is the chip supports 5GHz dual band. here
I don't think my 3D has connected to 5GHz on my home network. I have a dual-band N router, and I have 5GHz as the primary, so my laptop and media player connect to that immediately.
I only noticed my 3D on the 2.4GHz part of my network. I haven't tried manually connecting it to the 5GHz band, but if it could, I would have assumed that it would automatically.

Well, when it comes to "N", there are several factors that come into play. One, the wireless chip MAY be able to support the A frequencies, you're talking about additional code to make it work with rest of the phone. Antenna isn't an issue since 2.4 is half of 5.0. A 1/2 wavelength 2.4GHz antenna, is about a full length 5GHz antenna if memory serves me correctly (that and the 36hrs I've been up). Another thing that comes into play as far as the bandwidth is concerned is channel width. There is also MIMO too....but the phones will be basic of basic. The fact that N support is enabled is surprising, but it's most likely just a selling point. It supports the most basic N, with the smallest channel width, and clearly MIMO isn't supported. Routers can be configured to B or G or N only, sometimes combos of them as well. I use DDWRT on my routers and it allows virtually everything to be manipulated. Either way though, there is a lot of features to cram into the small area that is the cellphone, and if you ever take a look at a full featured ABGN mini pci-e WLAN card, you will see that there is still a decent size to it when all the features are present.
Ok, I think that's about all I can add to the topic, LOL
N is the technology that delivers faster then G speeds using MIMO packets.
A is the technology that frees up the crowding of B/G Networks by running on 5GHZ as opposed to 2.4GHZ
BGN Refers to a 2.4GHZ spectrum capable of running the N packets.
ABG Refers to a 2.4GHZ or 5GHZ spectrum capable of running the B/G packets.
ABGN Refers to a 2.4GHZ or 5GHZ spectrum capable of running BGN packets.
It's retarded how they label it. LOL but you can run N on 2.4 spectrum or 5GHZ spectrum.
Most mobile devices only see 2.4GHZ spectrum since they only have one antenna.

Actually, abg means that it can use the 802.11a, 802.11b, or the 802.11g standard, and abgn adds 802.11n. 802.11A is a very different standard than N, and is incompatible with the others, whereas B, G, and N are forwards and backwards compatible, except for N going over a 5Ghz signal, which still isn't compatible with A.
All that said, I'm pretty sure that this phone will only support 802.11n over 2.4GHz at 150Mbps. I don't have the phone yet, but I'm basing this off the fact that nearly all portable devices that use 802.11n are that way. At least I haven't seen one that is capable of either using 5GHz, or 300Mbps.

I have the exact same issue. My laptop sees my 5ghz ssid, but my MT4G doesn't. The weird thing is, I've flashed several ROMS to my phone, and none see it. I did however, flash the stock ROM (froyo 2.2.1) today for the sh*ts and giggles of it, and it saw the N ssid! WTF.

Does the bolt connect to wireless-n (802.11n) networks?

Trying to make my phone connect to my wireless-n network so that I can get much faster speeds on it. right now it seems to connect at wirelessg mode, and I know my internet can get around 35mbps. Getting very flaky 4g and 3g signal in my apt.
Yes, it does (depends on the kernel most likely though). However, you don't need a wireless N router to reach 35mbps. Wireless G will do 54mbps. My old wireless g standard wrt linksys router with ddwrt firmware on it outperforms a lot of stock wireless N routers you buy in the store. If you weren't aware, routers have lots of various after market firmwares like android phones do and are substantially better.

realistically, i get only about 21mbps on wireless-g (i think thats the real world speeds), and ddwrt is not exactly working properly on my router.

Wireless N-Only problem?

I was wondering if any prime owners tryed to connect on a N-Only wifi?? on the box it says a/b,g,n wireless but when i try to set my wifi to N-Only, i can see the network but theirs no way the prime is connecting to it. I have to switch it back to either Mixed or G/N Mixed, and then im able to connect with a max connectivity with router of 54mbps. This problem was present before and after ICS update, my router is a Asus RT-N12 (tryed with stock firmware, updated stock firmware and with DDWRT). I Would like to know if any of you guys tryed this out I feel i'v been kinda scammed
PS. (I checked out on Q&A for the prime and couldnt find any post related to this if you guys know there is already one, please just give me the link i'll continu posting on the other thread thanks)
I can't connect to my "N" router either. Mine doesn't even show up in my TF.
is it a TF prime or the first one?
N-5ghz is not supported, putting it in 2.4Ghz mode should work (at least, it does on mine... whether there's a difference or not is another thing)
I can connect my prime to my router with N only as long as its on 2.4GHZ and between channels 1-11. I wish I could pick up 12-14 because I live in an apartment complex with crowded wifi. Router is Cisco E2000 with DDWRT firmware...
The link speed showing on the network signal app only maxes at 54 mbps though. I can stream 1080p mp4s from my network drive though so its fast enough for me...
RT-N12 is operating on 2.4ghz and does not support 5ghz. Are you sure you are in "N-Only" mode or are you in "Mixed"??
This has been discussed in great detail in general section. Its known Prime can't connect to 5Ghz. set it to 2.5 or G only. G only seems tl yield best results. also check this article out..might help.
www.smallnetbuilder.com/wireless/wireless-basics/30664-5-ways-to-fix-slow-80211n-speed
Yes, it connects 2.5 N only but the performance is pathetic. Prior to ICS, I got curious changing my 2.5 GHz band to strictly G. Saw an immediate boost in performance + speeds.
Yes so far I am very disappointed. I just got the Prime today and it immediately updated to ICS. Once that was done I started checking out the wifi ability right away, because of all the bad reports all over the internet. Much to my surprise, mine doesn't see my wireless N either. I had the TF101 prior and it worked fine with my router. My Samsung E4GT phone sees it just fine, and what really hurts is my wife's iPad 2 sees it, connects to it and pulls just under 20mbps speeds.
To say this sucks is an understatement. I hate losing to Apple in any way, and here I am with the latest and greatest Android tablet, and being punked by a nearly year old IOS device.
Crap

What do you stream over 5ghz network to iPad? 1080p movies? It redundant...just turn down to 2.4 and everyone is happy.
Having a technically higher spec which does not improve on daily usage is redundant.

Exactly, the prime doesn't support the 5Ghz frequency. Only supports 2.5ghz N or whatever. There's only a few tablets that do actually support 5ghz. All it takes is a simple change n it'll work. THE whole argument that it should work on any network is b.s. Especially if you have it set to something not supported. Doesn't take a genius to figure that out.
I've always used N-Only. I get a decent connection to my Transformer Prime with it too.
Mines is the cheap Belkin N150 router so I doubt it does that 5Ghz range as that seem like a setting for a higher priced N router.

Point 1: Your are in the US, so you are not allowed using anything except 1-11 by FCC regulations.
Point 2: N-Only often turns on channel bonding in soho equipment like yours, so it needs 8 full channels to use it properly. Each channel is 5 MHz apart from the other and a WiFi device uses channels in a/b/g that are 20 MHz wide, in 11n with channel bonding (which is an optional feature for the high data rates) they use channels of 40 MHz. So dividing the 40 Mhz by 5 Mhz makes using of channel 14, 13, 12, 11, 10, 9, 8, 7. If you would live in Japan, on only country that is allowed to use channel 14. So for US it would be channel 11-4. This explains why channel bonding in the 2.4 GHz band is a band ides unless you are living in a big ranch 500 feet away from the next WiFi router.

Cool device, taken from the specs page of belkin.com:
Security: Wi-Fi Protected Setup, 256-bit WEP (64-128bit), WPA-PSK (TKIP), WPA2- PSK (AES) with WPS Push Button
Range of up to 1,000 ft.
Link Rate: Up to 150Mbps in 40MHz Channel Mode Bandwidth 20 MHz & 20/40 MHz auto
ISP Protocols Supported Dynamic, Static, PPPoE, PPTP, Telstra Bigpond, L2TP
Compliant Standard IEEE 802.11b, 802.11g
So no 11n support per specs, but the Overview page tells 150 MBits are supported, so it can run 75 Mbits without channel bonding and 150 with.
Try out the WiFi Widget it tells you the data rate to the WiFi router.

I spent the extra money to purchase a dual band router, so I could broadcast N and G as two separate signals. As I understand it, if you broadcast both on a single signal, and you have some older devices that require and connect to the G band, it will automatically cut the speed back, to whatever the slowest device connected is capable of. At least that is the way it was explained to me. So the N was on 5ghz and G was on 2.4ghz. It has always worked with any other wireless N device I have had, until I got this "latest and greatest" tablet. So yes now I have downgraded my wireless network to only 1 band, to accommodate the Prime.

If you have 2.4ghz g network, prime should be able to detect it. Check if your dual band is working properly...
Wireless n is impt only if you stream HD movies. I stream music on g with no problem at all.
I know you feel frustrated, and I know it sucks as prime is supposed to be PRIME. If you intend to stream HD movies to prime you may have to "down grade" to 2.4ghz if not wireless N is kind of overrated or "miss used" as I see no use of having to stream HD to non HD devices. If you are a home theater enthusiastic or business it then wireless n 5mhz is a must.
Hope you can move on to appreciate the quad core of prime than dwelling on this issue.
Cheers!

Wireless N or Wireless G?

Ok guys I read somewhere in here that the Prime did not play nice with Wireless N so here is what I did using my D-link wireless router:
Changed wireless settings from N to G only and ran some tests here is what i got:
WiFi Analyzer - -50/-44 dbm
Speedtest.net- Ping 17ms 8275dn and 2125up Average ( I have a 8Mb connection)
GPS Test - it now can see 9 sats and lock to them but the signal is still very poor (between 10 /20 SNR) so the navigation dops the signal but IT CAN SEE THE SATS!
Changed wireless G to N and this is what I got:
WiFi Analyzer - -61/58 dbm ( the lower the number the better the signal)
Speedtest.net- Ping 72ms 6420dn and 1233up Average ( I have a 8Mb connection)
GPS Test - 0 sats
Changed the wireless N to N+G and this is what I got:
WiFi Analyzer - -55/50 dbm
Speedtest.net- Ping 24ms 8225dn and 1790up Average ( I have a 8Mb connection)
GPS Test - It can see 4 sats but wont lock
What does it all mean???? I have no idea, all i know is that im going to leave my router on G from now on.
Can anyone else confirm and post? Thanks
>What does it all mean???? I have no idea, all i know is that im going to leave my router on G from now on.
It shouldn't matter. N's main advance over G is its MIMO transmission, 5GHz inclusion, and doubled bandwidth (40MHz) mode (some turbo-G versions have channel bonding, but they were proprietary and not interoperable between brands). The Prime has a single xmit/2 rcv ant (nix MIMO), single-band (nix 5GHz), and only works with 20MHz bandwidth. You should not notice a difference between N and G wrt the Prime. In fact, as the majority of wifi in laptops and PCs are of the cheaper single-band variety, this applies to those as well.
Many early N routers are draft-N, and N mode can be problematic, especially in mixed mode use. That's probably why some people noticed an improvement when they switched to G. Many people also use TKIP in WPA/WPA2, which also leads to slowdowns.
To answer your question directly, sure, change the various settings and see if they make a difference. But if you get an improvement in G over N, it probably means you should upgrade to a newer router--or at least find an updated firmware if one is available. The improvement would apply to other devices and not just the Prime.
BTW, since wireless performance is highly variable, you would want to take a number of tests and take the avg, rather than rely on a single reading.
That was a helpful post E.mote, thank you.

Many early N routers are draft-N, and N mode can be problematic, especially in mixed mode use. That's probably why some people noticed an improvement when they switched to G. Many people also use TKIP in WPA/WPA2, which also leads to slowdowns.
To answer your question directly, sure, change the various settings and see if they make a difference. But if you get an improvement in G over N, it probably means you should upgrade to a newer router--or at least find an updated firmware if one is available. The improvement would apply to other devices and not just the Prime.

or maybe is one more thing that the primes have wrong with them...don't get me wrong I love my prime and I DO NOT WANT TO GET RID OF IT i just wish there were some answers to all of our questions or maybe i should stay away from all the forums and pretend that there is nothing wrong with it and the $500 was money well spent. Thanks for your input
router is 2 weeks old and it has the latest firmware. (first thing i checked) the post does say Average.
Wireless N 5Ghz is so overhyped n overrated. It get less range than the 2 4Ghz band.
Read this tech article that shows how most people got scammed by 5Ghz band hype.

I work in IT field and deal with plenty of routers I will take G over N any day range is always much better which explains why Prime works so much better with G because of the aluminum backplate blocking some of the Wi-Fi signal the range isn't as good as your everyday Wi-Fi device dead spots about 10 ft difference.
Maybe this doesn't apply to some but with wireless g my speed tests are at about 15-20mbs and with N its the full 36-42 mbs. So if your internet is slower than 20mbs g is probally fine but I NEED n to work to get the most out of my connection.

So ive got 20mb internet and have the virgin media hub, wireless connection is awful upstairs, do i go with n or g and is the prime not compatible at all with n
The Prime operates in the 2.4ghz band, forget the 5ghz, it will do nothing for your Prime, I also made tests to my network and disconnected the 5ghz band after getting results like the OP. ATM, my network operates G only and I'm getting great results.
Cheers

I would definitely go with wireless N. If you have problems like very slow speeds switch back to G.
The prime seems to support wireless N speeds up 65 mbs.

N has better throughput and range, assuming good antennas on both ends that allow for MIMO/dual-stream use. G is needed for legacy pre-N devices. I use both.

Options to boost wifi in your home:
. Try a different router. Routers can vary in performance.
. Repeater (old router retrofitted with DD-WRT firmware) to extend your router's range. Repeaters aren't common as consumer products nowaday, since they need some knowledge to set up.
. Powerline adapters (pair). These are convenient but relatively expensive. Advertised for ~200Mb/s, but more realistically 100-150. They're getting more common; most vendors have a line. Performance depends on house electrical wiring.
. MoCA adapters, assuming house is wired for cable-TV (RG-6 coax). These can also be expensive, but you can hunt around for older stuff on eBay for cheap. It's more reliable than powerline.
I dropped 802.11g long ago like it was hot like I did 802.11b before it.
802.11n is now, the Transformer prime supports all of them and changing wireless broadcast to anything lower than N is just to give you less of what's current and best.

Not really if the devices you own don't "see" the 5ghz frequency, only but the newest electronics operate on that band, you Prime don't for example, and it's new.
Cheers
After reading this I was interested to see if this was having any effect. I tried several different settings:
G - only
N - 20MHz (single channel)
and N - 40Mhz (channel bonding)
I found that by far the best setting was single channel N. I've gone from having virtually no usable connection in parts of my house, to a usable throughput in all parts of the house. Also did some tests using WiFi analyser and speedtest.net and found consistently higher throughput and signal strength using this setting.
My conclusion, it seems to have a problem with wireless N channel bonding.

I don't have a dual band N router but if I did I wouldn't set it to operate in 5Ghz only mode, I would keep it functioning as a dual band mode so both 2.4 and 5 Ghz bands were active for complete 802.11n functionality.
That way all my N devices would see the N broadcast.
That's the point, I do have a dual band router, I tested the network with both frequencies on, and disconnected the 5ghz band after testing the 2.4ghz alone, the network signal is weaker with both on.
If you stream alot of video and have devices capable of taking advantage of the higher frequency, very well, if you don't or don't stream that much video anyway, having the 5ghz on, doesn't make any sense. In my case, weakens my signal, it works for me to shut it down, maybe for others this doesn't apply.
Signal strength depends of so many factors, the environment where a network is set, strongly dictates the outcome in performance and stability of it, no network behaves the same. My network is working in top condition for the environment around it, that's what it matters for me.

[Q] 5GHZ Wifi

I was surprised to find that this phone supports bot 2.4GHz and 5GHz for wifi. However, I am having a problem getting it to connect to my 5GHz N radio. It will see it and says that the signal is excellent. I type in my WPA key and hit connect. It attempts to connect then goes back to disconnected. If I click on the name of it, it show signal as poor and link speed as -1Mbps. It connects fine to the 2.4GHz radio. The router is a Buffalo WZR-HP-AG300H running DD-WRT. Has anyone else had this issue?
i thought wifi was only 2.4ghz on this phone. my 5ghz network doesnt even show on my phone.
5ghz seems to be working fine for me
only certain 5ghz channels are supported. see if ur router is on channel 36 for 5ghz.

I have been able to use channels 140 and 149 as well as 36. What I did notice is that the first time I connect to (the very first time or if I make a change to the router) the wifi signal will drop and start several times.....I find if I just turn off wifi and turn it back on and reconnect it will hold.
Actually, I have it running on 144 and working now. I had to set the mode from N only to NA mixed.

Hmmm...mine is set to N only...being its the only device on my 5G connection.
Yea, the only thing on mine is my other router setup as a bridge for my downstairs. I guess ill leave it since its working

I've got an apple airport extreme. my evo connects just fine on 5ghz
I have a Cisco ISR wireless router and I use strictly 5Ghz. It's wireless-A, not wireless-N, but it's strictly 5Ghz and it scan and uses whatever channel it wants. No issues so far.
I tried N network a while ago on my older phones (not 5Ghz N) and noticed more battery drain VS G. Since then I have switched my N to 5Ghz and just use my ipad3 for it. My phone I keep on G network. I don't see any real point to having it on a N network. G I still pull 10+ megabits down which is more than enough for pretty much anything the phone can do. Not really worth the extra battery drain in my opinion. My ipad I like on higher speed since I stream MKV files but the phone I think is pointless at least for me.

I actually had the exact same problem as you mentioned. The one thing I wanted to add to your excellent description of problem symptoms is that it says "Authenticating", and that is when it drops the signal to -1Mbps. Something during the authentication process seems to kill the radio connectivity. This has not happened on any of my other 802.11n devices. It connects fine on the same router's 802.11g. I had no issues with my previous phone (Samsung Epic Galaxy S).
Interestingly my router is a different brand but perhaps it shares some similar chipset. My equipment as follows:
Bone stock Sprint HTC Evo 4g LTE (on Ice Cream Sandwich, duhh)
Belkin Play N600 HD Wireless Dual-Band N+ Router (F7D8301 v1)
After reading the other posts here it inspired me to play with my Router configs for 802.11N. Turns out after making some adjustments I was able to get connected.
-I had the following selected:
Wireless Channel: Auto
Extension Channel: 40 (grayed out)
Wireless Mode: 802.11a&n -Worked after changed to 802.11n
Bandwidth: 20/40MHz
Protected Mode: OFF -Worked after changed to On
802.11e/WMM QoS: On
I honestly think it was the Protected Mode that made the difference. Here is what the router help page says about that feature: Protected Mode
NOTE: In most situations, best performance (throughput) is achieved with Protected Mode OFF. If you are operating in an environment with HEAVY 802.11b traffic or interference, best performance may be achieved with Protected Mode ON.
So long story short, try turning Protected Mode ON in your 802.11n configs first and see if that gets it going for you. Hope that helps!
P.S. After changes above I ran some Speedtest.net for Android tests (back to back) and got the following from the next room over (about 20 feet from router):
Test 1: On 802.11n: 17024kbps down, 5857kbps up, 27ms ping
Test 2: On 802.11n: 18134kbps down, 6266kbps up, 39ms ping
Test 3: On 802.11g: 15385kbps down, 6091kbps up, 25ms ping
Test 4: On 802.11g: 22212kbps down, 5785kbps up, 43ms ping
