I used to be able to connect to my 5ghz wifi network without a problem. It stopped working recently when I flashed one of the CM9 ROMs. I thought it had something to do with the ROM but it was working on earlier CM9 builds. I flashed back to Task650's v14.1 ROM where it used to work fine but I still can't connect. It sees the network but when I click connect it doesn't do anything. I haven't made any changes on my router and I can connect to my 2.4ghz network fine. I have a Linksys E3200 router with the 5ghz network setup on channel 36, 40mhz channel width and WPA2 personal security. I've tried changing all the settings on the router but i still can't connect. I did Odin back to stock last week because I was getting a lot of reboots on the CM9 ROM I was running. After that I flashed CWM and then flashed the latest CM9 ROM. It seems like the trouble connecting to my 5ghz network started around that same time.
Does anyone have any idea what problem could be? I have a 7510 32gb Tab.
Thanks.
Does anyone have this issue? I Odin'd back to stock 3.1 and I still couldn't connect to my 5ghz network. When I click on the network it doesn't do anything. I found this issue with the galaxy nexus connecting to 5ghz wifi - http://code.google.com/p/android/issues/detail?id=22474. A lot of the posts on there describe the exact same problem I am having. I used to be able to connect fine then it stopped working. It was working fine on the stock ROM, all of Task650's ROMs and all the CM9 KAMGs. I was flashing a lot of the CM9 ROMs during the time it stopped working. It could be a hardware issue, but the fact that it sees the network fine makes me think it's not. I recently upgraded the firmware on my router and did a factory reset on it but that didn't help.
I have this same problem on my Galaxy Nexus. Put your phone really close to your router (a few inches) and I bet it will connect on the 5GHz band.
If it connects at really close range then you know the hardware is damaged... my guess is samsung has some kind of serious design flaw in their phones for this to be happening to so many people on different models of their phones.
5GHz bug?
I recently discovered that my Tab 10.1 works with low channels (eg 36) but not high channels (eg 149). I was surprised to find quite a number of postings about the same issue. Is there a firmware issue or is it a bad RF chip? It seems Samsung has a problem...
If anyone is still having this problem I found something that worked for me. The info below is copied from this issue http://code.google.com/p/android/issues/detail?id=40999#c4
"...only channels 36, 40, 44 and 48 work for 5GHz on the Galaxy Nexus. (My AP was on auto and blasting on # 149).
I manually set it to 48 and presto I was connected."
There's an error in the configuration file- /system/etc/wifi/nvram_net.txt
Take a look at the thread here http://forum.xda-developers.com/showthread.php?t=1866908
RIght, firstly I've got a UK Z2 (Vodafone model, but unlocked and subsequently flashed with a different ROM).
My problem is that I can't connect to a router that only operates on the following channels at 5GHz; 149. 153, 157, 161.
These are apparently valid in the UK, although my iMac won't see them - but it's a 2009 model. My MacBook Air (US import) does, and my Z1 Compact (with EU Generic ROM) does. So does my Xperia SP. The Z1 I recently sold did too.
Now I assumed that the UK ROM, and now my Taiwanese Z2 ROM (the router is Taiwanese too), supported it because when I turn on the phone, it can see the router. However, it can't connect. It never gets an IP address, and then soon after it disappears never to be seen again! That's unless I reboot, but even then - sometimes - it won't show then either.
The Wi-Fi signal is excellent.
I've read before (for the Xperia Z) that you need a SIM card inserted, and there is. It's a Three UK SIM. That perhaps tells the phone what channels to use? But if it thinks these channels are not allowed, why does it initially show the router? Is there a delay before it notices what can't be used? And why would one UK SIM hide the channels, but not another?
In any case, my Z1 Compact currently has no SIM card inserted but still works.
I'm very confused. It doesn't appear to be a hardware issue (it would be a weird problem if it was), so it must be down to the ROM - and I've had both .55 (Vodafone original and then a EU generic) and now the Taiwanese .69 ROM.
Sorry for the long post, but I wanted to try and pre-empt any questions that might get asked.
Basically, is anyone else having the same issue and does anyone know a potential solution? I can't change the channels on the router and there's no other firmware for it. Obviously I could change the router, but I think I'll just have to stick with 2.4GHz in that case.
I know you say no fw is available for the router but im assuming you mean stock? Is dd-wrt/tomato available for it?
My s3 was the same on every custom rom i tried, 5ghz was always iffy :/ Will let you know if 5Ghz works for me when my z2 arrives friday
5 ghz works for me but not using the mentioned channels, in fact my router Won't even allow me to use those channels.

The thing is, the router is from Taiwan and there doesn't appear to be any way to change the channels it operates on. For 5GHz, those four channels are it.
They do appear to be legal in the UK, but many devices won't support them.
I am just confused as to why the channels work on the SP, Z and Z1 Compact but not the Z2. And even more confused because it will show up for a little while but not connect, then disappear. That's an odd way of restricting Wi-Fi channels on the part of the handset.
Can you maybe doing a forget network and then re-adding it?
I'm in Singapore and have no problem connecting to 5Ghz channel 161.
I don't think it makes much sense for them to limit channels on the client side as people can travel anywhere with their smartphones and should be able to use any channel available..

Yes, but some devices do still restrict channels - based on what region you've set, and possibly in this case the SIM card.
I'll need to do further tests, like swapping the SIM for one, to see if that makes it work. At least then I might be in a position to report it as a bug to Sony.
I have removed/forgotten it when it was there, forcing me to re-enter the code, and it just doesn't connect. And while it isn't connected, it does then stop the phone connecting to anything else unless manually select it.
whats the make/model of the router?
Can confirm 5Ghz works just fine for me using Doom's kernel and Aur

I previously owned a Z1 and found that 5ghz wifi was very poor on this device.....I now have a Z2 and the wifi is exactly the same.......works well on 2.4ghz, but poor on 5ghz. My wife's Nexus 5 works well on 5 Ghz so it must be down to Sony's implementation. I am using channels 36-48 not sure if I can access the higher channels, I presume not....think my router only has the lower channels......I have searched the web before for an answer to the problem, but no luck as yet....:crying:
just to add my 2cents to this, My UK bt homehub doesn't have those higher 5Ghz channels highest is 128 lowest is 36
Yeah, this has happened to me recently aswell. I used to connect the 5GHz 802.11ac wi-fi network at home on my Sony Xperia Z2, but a couple'o days ago it disappared. I can't see the 5GHz signal, I'm using 2.4GHz instead. But my laptop can see 5GHz signal and connect without any problems. The channels on 5GHz signal is 149,153 by the way. And channels 11, 7 on 2.4GHz signal.
So what might be the problem within my Sony Xperia Z2?
Thanks in advance.
Oh I just relieved that this problem is not only for me... Okay as some people mentioned wifi for Z1 was poor and Z too... so it might be problem w/
design of Z series. I am using AC-7260 wlan for my PC and seeing 5Ghz AP. But not for Z2....
No jamming around my home, no one is using 5GHz other than my AP.
My Z2 works excellent on my 5ghz channel. I'm on vacation now so can't verify the channel I used. What I do know, is certain devices don't work as advertised with 5ghz. Just because one device sees it doesn't mean every device will. I've had to switch channels a few times for different phones although my laptop has always seen it.
Yeah, it must be the channel issue, I suppose. But at first, my Xperia Z2 was connecting to 5GHz signal without a problem... After a while this issue started. I didn't change any channels or something on my router, either. Interesting...
5GHz signals have inherently smaller ranges than 2.4GHz ones.
That said, my Z2 connects to my 5Ghz AC network just fine (range sucks though) but it has a problem keeping the connection to the 2.4GHz N/Mixed network from the same router (dualband ASUS RT-AC66U) alive after a period of time. It will still show as connected (with good signal strength) but will not have any access to anything else.

Yeah, I'm well aware of this range thing between two signals. But my problem isn't something about it. My phone used to see and connect 5 GHz signal, but it doesn't see 5 GHz signal at all now. Even when I put my phone right on the router, between 6 antennae. (3 x 2.4GHz, 3 x 5GHz antenna)
This must either a software issue, or channels on 5GHz signal... But no, my phone was connecting without any problems for 3 weeks with the same channels. Must be software.
This isn't my only problem with wifi anyway, there's also a Bluetooth interference with 2.4GHz signal. Happens when Bluetooth is on at the same time with wifi. And when connected 2.4GHz signal, connection drops sometimes.
i found this thread now i had posted one earlier today.
what I have figured out is - the moment the SIM is inserted Z2 is taking off the channels that are not "legal" possible in the country determined by SIM.
I am on Telkomsel - indonesia, if NO SIM - I am able to connect on 5 GHZ very well. but once it senses the SIM card, the 5 GHZ vanishes.
This never happend on Z Ultra!
next step is to test on other channels on the router in 5 GHZ to see if it is limitation of Z2. Right now my router supports only 4 channels - 36 40 44 48 on 5 ghz band.
otherwise my mac and other units connect and work pretty well on these channels!
Alright, I've had my Xperia Z2 for 3 months now. I've never connected to my 5 GHz 802.11ac signal before, the phone doesn't detect it. I can only connect via 2.4 GHz band.
Why my phone doesn't detect 5 GHz wifi signal? What's wrong? What do you suggest?
What ia the max link speed you get on 5ghz in z1 compact
I don't know if anyone with a Z2 still has this problem, but I did and I seem to have fixed it by not setting my router to VHT80, but to HT40 instead. As a side note, my Chromecast seems to be able to connect to it now, too. My router is a Netgear Nighthawk (R7000) running the latest DD-WRT Kong Mod.
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?

Hi Phil
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!

Yeah.. Only 34-48 Weird why it doesn't support more than that.

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.

its suposed to work check if your router router chanel are setup correctly
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

Hi,
I bought the tab last friday. While playing around I noticed that Wifi does an

Could anybody please try? Turn off your router's 2 GHz and use 5 only.
Watch the Wifi nenu in your tab.

My tablet is connected to 5 gigahertz exclusively and has never dropped the connection. You may want to take a look at your router's wifi settings.
I have a brand new Galaxy Tab S3 SM-T820 Wifi version, and I have two wireless routers in my home. One is a RavPower ND007, the other a DLink DIR-813. Both are dual band routers. On both, I have the 2.4 GHz network and 5 GHz networks names differently. Every other device in my home - including a number of Samsung devices - connects to all four networks with no problem.
However, my Galaxy Tab S3 does not. When connecting to the Rav, it shows "Connected, No Internet", and can't communicate at all. It won't even connect to the DIR-813 at all.
It connects flawlessly to the 2.4GHz networks on both routers.
Both of the routers, and the Tab, all have the latest available firmwares/updates.
So it's definitely the Tab S3, and definitely a 5GHz problem.
Not sure how to report this to Samsung, but I'm going to try...
defenitley YES, 5G problem...

Last Sunday I forgot to turn off Wifi 5G on my router and used my Tab S3.... Reconnect each 2 seconds... Super Quality, Thanks a lot to Samsung..
And just to clarify - 5G works with the same router and my Phone S8 perfectly, so it is NOT a rouoter issue...
I've been using 5G exclusively as our SSID is 5G specific and never had an issue with WiFi. Solid connection 100% of the time. Netgear Nighthawk X8 here.

Will try to install the latest update this weekend, without any modifications. If 5G still does not work, I will send the Tab to samsungs repair-center, as it still will be covered by warranty.
Either it is a problem with modem-driver or Hardware..
But nevertheless, this is the very first device showing up this problem with 5G.
If Samsung is not capable to solve, this will be my last product purchased from this brand...
I did send my Tab to Samsung repair center in Germany. Will receive it today, but I already know that they did not find any problem, all fine..
Well - but they did not give me a detailed test-report yet... So I dont know what and how they tested..
Will return the Tab to my local dealer for replacement..
I'd like to test with a different SM-T825...
Reading this I haven't seen that you've tried updating your router's firmware. If you haven't try that too. I'm not sure if when you say "install latest update" if that's the router or the tab.

Just by chance I found out, that 5G works if no SIM inserted. And IF SIM is inserted, it MUST be active. In flightmode and then activate WIFI does NOT work..
This is very suspicious... I hope that SOON we will find a working lineage for the galaxy tab S3...
Galaxy Tab S3 SM-T820 Wifi version and dual band 5ghz
Hmm, I just updated my modem as per better speeds from Comcast, but I also need a new router that would take advantage of the bandwidth and the 802.11ac dual band standard so that I can get to the 5ghz band.
I own a Galaxy Tab S3 SM-T820 WiFi and before I get a new router, I want to know if the WiFi adapter in the Tablet would pick up on the 5ghz band with a new router. Is there any type of updates or drivers or am I okay?
Thank you,
Jon
I'm on 5Ghz all the time. No issues.
Great news !!
I asked the question after I learned about the variety with routers and especially since I found out that my laptop's WiFi adapter only supports b,n,g and that I would need to buy a USB WiFI adapter for my laptop or somehow change the adapter chip inside my laptop to take advantage of the 802.11ac dual protocol.
Thank you, Jon
I have the t825 version, unfortunately I have problems with the 5 Ghz connection.
I hope Samsung releases an update to fix the connection problem and to improve the camera

Hi, I have the T835 and I have the same problem. It disconnects 5 ghz, problem since I bought it.
Sorry, I'm wrong with thread
Hi all, Recently got my m5 from eBay here in the USA. I have a lot of questions but the biggest one is the tablet isn't seeing my 5GHz network. It connects to the 2.4GHz network just fine and we have a house full of other devices that connect to the 5GHz network so not sure what is going on.
To be clear, the 5Ghz network isn't even an option to select.
Model: SHT-W09
Build: SHTW09 8.0.0.151
Probably you are using a channel which is not supported? For me the 5GHz connection is working without any issues.
Try manually entering the ssid.
Try a factory reset. I have 5ghz on mine
Thanks for the idea. That worked. It was on auto channel using 149. Moved it to 40 and it can see and connect now. Thanks again!
