I actually have an asus rt-n58u router (which is SUPER fast and strong), yet I could only get like 5 mbs on my prime! Great signal, but no speed for some reason.
I had the 2.4ghz N-only on channel 11 originally. When I moved it down to 1 or 3 in the 20/40mhz range, it upped the connection speed 5x from where it was so my transformer is connecting at 54-72 mbs instead of the 19 before.
Odd, but give it a try on your router and see what works!
That kind of makes sense - lower frequencies are better able to penetrate solid substances, so it might make the signal strength better.
It's very odd, however, that a drop of only 40 MHz would have such a huge influence if that was the reason. Are you in a highly-populated area? I think it's more likely that there was interference on the other channel. Do you have any other wireless devices to test with? Did you try putting it back to the original channel and seeing if the speeds went back down? Also, were you holding the tablet in the same position during both tests?
I live in a small condo complex, but I used wifi analyzer to see what channels the other networks were in... At my old 11 channel, there were zero, while at 3 there are 2 others to contend with. My laptop works at 300 mpbs at either channel but the prime seems to perform much much better at the lower frequencies.
Odd part is that the signal strength was the same between channels 3 and 11, the only thing that changes was the speed thoroughput. Suddenly the speed listed in Android went from 5mpbs to 65 ish by just changing the channel, yet the db- signal strength remained very good.
If anyone can explain this, I would be all ears.
I recently used Wifi Analyzer to change to channel 11 from 1. Why? Farther away from my router 11 was stronger than 1. So maybe speed is sacrificed by distance & vice versa? Wifi Analyzer also tells which channel is "better" but is it using "better" as determined by???
Interesting, I am playing around with the channels as well, and there seem to be differences in speed of each channel.
I live alone in the woods, where definitely no intereferences from other WiFi Networks appears.
Channel 11 works slightliy faster than channel 1, but I have not tested many configs yet.
The signal strength is not the issue because I am sitting right next to the router, but the speed behaves odd.
I cannot connect to my DLINK DIR 655 on channels 6 and 13, no problems on others.
The Prime WiFi wierdness continues

It determines better based on the channel of other networks in range. So the higher the channel rating, the fewer other networks there are in that frequency range.

looking at this from a physics standpoint, this makes sense. lower frequencies use more energy and so at a higher energy, you're able to pump out more speed. I'm guessing it's the prime that's using more energy since the router is not the device in question...
interesting though...you would think that it wouldn't make such a big difference!
FWIW, I've always gotten much better performance on my wireless network in both terms of speed and connectivity, using channel 1.
what app are you guy suing to test speeds? Speedtest.net

Yup. That seems to be the standard app for speed testing. If you really want to be accurate, the best thing you can do is transfer a large file locally over your WiFi network.

Interference. Other Overlapping wireless routers.
I'm a little skeptical of the OPs findings, as the difference in channels (in the tens of Mhz range) shouldn't make a significant (and definitely not a factor of five) difference in bandwidth. It is interesting though. Can you do some controlled test runs and provide the specific data?
I am just as confused as everyone else...but trust me it makes a big difference.
The DB rating at channel 11 was -40 (lower better), while the DB rating at channel 1 was -38. Again, channel 1 is crowded with other routers, yet 11 or even 14 is empty (no one knows how to properly use their router here!)
I would have full bars (according to android) at the higher wifi channels, yet the prime would only show 5 mbs, sometimes 19, but most of the time around 13-19mbs (per android menu, speedtest around 7 mbs). When I moved to channel 1, the prime (and my droid charge) would go to 52-65mbs (android, 13-15 using speedtest)...but my computer would go to 144mbs only because of no channel bonding.
Moving to 3, a 40mhz channel, my charge would get 52 mbs and my computer bonded to a full 300mbs. Channel 11 is a 40mhz channel too so not sure why 3 is any different than 11 that is also 40mhz, but the speed rates in android is consistently higher.
The test is through one wall, about 20 feet from the router. Could be just my router, but who knows! I have an Asus rt-n56u router, with dual bands. I would be curious to see what the tests would be at the 5ghz band if that was ever enabled in android.
My tests were in a controlled place, same spot for laptop, droid charge and my prime. All i did was change the wifi channels from 11 to 7 to 3 to 1 and see how it changed the speeds.
I measured the rates speed provided in android from the wifi interface and also used speedtest on all 3 to rate actual speeds. speedtest results went from 6-7mbs at channels 11, to around 15-16 at 1. Just checked again this morning and still faster.
Here is a wiki article picture on the bands:
http://en.wikipedia.org/wiki/File:NonOverlappingChannels2.4GHzWLAN-en.svg
I also got a significant speed boost from moving off channel 11 onto 1. Went from 3mbit to 14mbit
I am about to conduct my own channel 1 versus channel 11 tests right now...
I've just tried it on mine and Channel 1 and 11 were near identical and 3 halved my DL speed.
Did the most scientific test I could. Never moved tablet, same environment, same location, 10 feet from router, Los Angeles server, ran 5 tests as quick as possible on each channel - with 3 minutes in between to change channels and let the change settle - and then spent 3 minutes watching dbm strengths on each after all tests complete
CHANNEL 11 =2462mhz
0. ping ms/ down mbps / up mbps
1. 24 / 20.15 / 1.15
2. 22 / 20.44 / 1.16
3. 21 / 19.92 / 1.16
4. 18 / 21.81 / 1.17
5. 24 / 21.26 / 1.17
*high and low dbm over 3 minutes -36 to -47
CHANNEL 1 = 2412mhz
0. ping ms/ down mbps / up mbps
1. 21 / 19.84 / 1.16
2. 22 / 20.57 / 1.15
3. 23 / 21 / 1.13
4. 21 / 20.79 / 1.16
5. 23 / 20.34 / 1.15
*high and low dbm over 3 minutes -39 to -43
Results = Negligible differences with 1 real benefit to channel 11 shown by Wifi Analyzer is that it reachs around my home farther. Channel 11 seemed to stick to better dbm ratings but had wider range in high to low but stayed mostly in 30's. Channel 11 got the best average up speeds barely. Channel 11 got the best average down speeds barely. Channel 1 barley had best average png. As well, of the other neighbors signals I pick up, most are in 1 and 6 - no one on 11 but me. Thus, I will stay on channel 11 for all obvious reasons.

Looks like maybe you conducted your tests close enough to the router that the bottleneck is in your internet connection, rather than the wireless connection. Try again far enough away that the connection drops to like half of that speed on channel 11. If the speeds are still the same then, that will be strong evidence that it's local conditions causing the speed boost for those who report it.
This may be related to your routers and not the TF.

Easy enough.. will do maybe tomorrow at same time of day to try to best mimic and remove confounding variables best as possible (though saturday may have more congestion as people are home). Either way, will do in my living room, farthest point from my router. Will be interesting to see how distance changes results.
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
I have no wifi issues with my N router... Performance can be a little better (speed wise) but no issues connecting at all, my router is cisco

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!

it only connects to the 2.4 Ghz a/b/g mode...
Desn't work even if I set the "N" mode to 2.4 Ghz channel and turn OFF the a/b/g mode.

Just got my Nexus 9 today from Google Play store UK. Everything seems working ok, except:
I cannot find any wifi 5GHz. I am connecting to my home 5GHz (Virgin Media Superhub) from my HP Pavillion laptop, MBP, iPhone and iPad. But on Nexus 9, I am not able to scan any 5GHz network:
2.4Ghz works fine though:
I have enabled all possible channels in Settings (Wifi Analyzer):
In system Settings, I have tried both Automatic and 5GHz only:
I have performed OTA updated after first time switched on device and connected to 2.4GHz network at work, didn't notice whether there was an issue on 5GHz until I got home.
So, is there a problem with the latest OTA, or simple this unit needs to be RMA?

Mobile devices don't always support all the 5GHz channels that an access point might use. Try setting the Access point to use the lowest channel, say 36 and see if that works?

Thanks for the hint. It looks like Nexus 9 only able to see channel 34 ~ 48. My broadband AP has selection of 36 ~ 136, and it was on "Auto Performance" and auto selected channel 100 tonight.
Thanks Phil!

Different countries have different requirements, but often most countries only allow certain frequencies to be used outside, and other frequencies for 5GHz may only be used inside buildings to prevent interference to radar etc.
A mobile device can of course be used outside, so can end up only being setup to use much fewer frequencies than a router designed for indoor use.
Sometimes the router isn't set to the right country, so ends up using frequencies it shouldn't really be using with the mobile device correctly set so ignoring those frequencies or the other way around. 5GHz is a lot more complex for what frequencies can and can not be used, see here http://en.wikipedia.org/wiki/List_of_WLAN_channels and the chart at the bottom, you'll understand why 5GHz devices sometimes don't see each other, it's a lot more confusing than 2.4GHz.

Using 5ghz wifi
Hi
To use 5ghz have you tried configuring from WIFI from settings - tapping the three dots next to the magnifying glass - Advanced - WIFI Frequency band.
It gives you the option of selecting 2.4 or 5 or both.

i had the same problem! Thank you so much for the fix!
You should be able to use channels 149-161 as well, it's the channels in between that are set aside for DFS and radar, so many devices don't support them.
Working fine for me on Channel 153 with a Nighthawk R7000.

Got mine to connected on the Virgin Media Superhub by changing the channels as suggested. Can confirm it works but very unstable and keeps dropping connection.
I got the same problem.
I got the same problem! I bought my N9 on Nov 11 and used 5GHz without problem until today. In the WiFi Analyzer suddenly can show 2.4GHz only. I have reboot and clear all WiFi App cache & data., still cannot show.
Even connect to 2.4GHz, it took long time to Connect and Authenticate the connection.

Been a while, but since this is one of the top Google results, and I've been pulling my hair for a couple of hours without finding a solution online, I thought I might chime in with what I found.
If your N9 is not seeing certain 5GHz channels, what is your model, WiFi or LTE? Also, apparently there is an "international" version of the LTE one, which I just got (I'm in the US) because it was cheap, and I didn't mind it affecting certain LTE bands, but I didn't think it would affect WiFi. In any case, the solution was to simply insert a SIM card from my region (T-mobile US) and the missing 5GHz networks appeared in the list. I don't have a solution if this is happening with WiFi-only Nexus 9's though.
You need to insert the SIM after turning on the tablet. If you turn it on with the SIM inserted, it won't show the hidden 5GHz channels. You can just reinsert it, or toggle off/on airplane mode though.
I also googled to see if there was an app to change Wifi regions, but the only one I found (from XDA) requires root, and doesn't work for this particular problem anyway.
Well I have never been able to connect to the 5ghz channel until now. Finally! Changing the router to use channel 48 for the 5ghz and it is running as expected. I love fixes like this.

Do you have a Wi-Fi or LTE model? If you have an LTE model have you tried inserting a SIM card like I said in the post above? I got access to the upper channels which are supposed to be higher performance. From 149 to 161.
whats the highest linkspeed you guys are getting? my nexus 6 gets 866Mbps , i guess it dpends on your AC router specs mine is ac1750 i think
what app do i use to check what channel my nexus 9 is connected to? i think its below 36

I use netgears wifi analyzer.
Anyone Oneplus 9R, come with 12GB RAM, 256GB ROM flash to Oxygen have 5G(AC) WIFI sigal?
same problem on mine. Seems some 5Ghz channel works, but not all (44 works, 147,155 wont work in my test)
Interesting. I wonder if this is due to the SoC.
Can you guys spot these specific channels here? https://en.wikipedia.org/wiki/List_of_WLAN_channels
Like are they "not normal" somehow?
Hi there.
My two cents.
My 9R only see WiFi 5Ghz channels between 36-64 and 100-128.
Other channels are not seen or connected to.
I checked using an app called WiFi Analyser.
In these channels I do connect OK using a Netgear R7000 router.
Lower channels have better speed in my tests.
The problem is my old Oneplus 5T could see and connect to the full radio spectrum, all channels from 36 to 144.
Missing these channels is an expected behavior for the 9R?
(Spec sheets on gsmarena doesn't talk about these details. They only say that the phone is WiFi dual band compatible)
Hi folks,
My A21s can't connect to nothing greater than 72 Mbps. My laptop connects to the same router at 300 Mbps N. Is this a phone limitation?
EDIT: I'm on 40 MHz channel width.
Well the title says it all when on WIFI 2.4Ghz the channel width can only be 20Mhz despite the router being at 40MMhz channel width. This effectively halves the internet speed the phone receives.
Issue emerged after the latest OS upgrade to Android 11 that was done in April 2021. Before this, the phone was able to use 40Mhz channel width at 2.4GHZ WIFI.
Sidenote: I have verified that only the Galaxy A70 faces this issue and no other device I have has this problem. Also tried with other routers as well that were on 40Mhz channel width and the problem there persists as well for the A70.

It's explained! Is there any way of bypassing this?
