suddenly can't connect to 5ghz WiFi - Samsung Galaxy Nexus

Hi all,
Yesterday my gnex stopped being able to connect to my home 5ghz network. Nothing has changed in the router and connection to 2.4ghz network remains perfect. All my other devices (imac, two ipads,a win7 laptop and a win 7 desktop, and an iPhone) can still connect perfectly to the same 5Ghz network.
I have not changed my rom recently either. I've been running slim bean 4.3 stable release 1 since it came out, all the while using 5ghz with no problem. I have tried switching to every available channel on my router and there is no difference. This literally came out of nowhere with no change on the phone or router preceding this problem.
I have noticed that if I stand right on top of the router, literally within two feet, it will connect and work. But if I move more than two feet away, it will show some reception bars but no data will be transmitted, and it will eventually disconnect.
In the app inSSIDer the network appears, but when I'm in the other room it will be grayed out with no label at times, but the signal strength is equivalent to what it was when it worked (which was the last two years).
After reading several forum posts around the Internet (like https://productforums.google.com/fo...ic/nexus/X80hGyTmusI#!topic/nexus/X80hGyTmusI) I tried clean flashing the 4.3 ROM again. Then I tried downgrading to 4.2.2 slimrom (a fix suggested by many posts), but to no avail, both times with a full wipe and clean flash.
Any ideas? Thanks in advance.

5ghz band has always done that on my nexus. It's a PITA

Won't connect to Cisco E4200 router with N only G!

Hi,
Just received my Galaxy Nexus earlier today and have been battling to have it attempt a connection to my WiFi router at home, it'll have a go at the neighbours routers but just says 'saved' on mine and never connects or fails regardless of password given or settings used.
Well - I just found the issue, if I set the E4200 to 'G' mode the phone connects perfectly, but it WILL NOT connect to the router set to 'N' speeds on 2.4 or 5GHz using 20 or 40 MHz channel width.
Anyone found there are potential issues with this phone and 'N' routers? I should mention I've tried 3 different kernels (stock, modaco and franco) and 3 different ROM's (4.0.1 stock, 4.0.2 Revolution HD and 4.0.3 build in the dev section) and all exhibit the same issue. Have not changed baseband as I'm using a 'T' model and want to keep my I9250TDVKK6 modem - this is probably where the problem is anyway.
Anyone else having similar or found a workaround or solution? Thanks!
Hi,
have you tried settings the MHZ band on auto or anything besides just 20mhz band? not many devices like this channel, I'm not having any trouble on the Aerohive system at work or other Netgear at home.
Thanks for the thought! 20 is standard but I've tried every setting - it will connect on 2.4GHz using 'G' fixed speed/protocol or 5GHz only using 'A', neither works at all on 'N' on any channel, width or security
It is bizarre, it's like the phone decides it won't try and says "saved" on the profile once the password is put in when its on "N" there is no connecting, authenticating or getting an IP feedback at all, it does nothing really. If I choose another working AP after trying an "N" one the "N" one says 'disabled'.
My SGS2 worked flawlessly and without complaint previously on any "N" or otherwise setting.
I have the same model router, and it is working for me. I have both the 2.4 and 5 ghz set to mixed network mode. Channel width set to auto, and security/encryption matching on both frequencies. On the Nexus, I have the 5 ghz specified in Wifi settings.

I have this model and connect via the 5ghz connection with no problems.
Same with E3000 with DD-WRT and Virginmedia Superhub
I've been suffering with this problem for a while now. I bought mine on the 19th Nov and tried it out in pure 5 Ghz mode almost straight away and was very impressed with the throughput from my 50Mb Virginmedia cable connection (40+Mb/s with Speedtest.net app).
All was well until I suddenly couldn't connect. It said the SSID was saved and the signal was excellent but tapping "connect" did nothing. I presumed my phone was acting a little screwy so did a had reset (stock unrooted 4.01F YAKU) and tried again but still suffered the same problem.
I started to suspect it could be a channel issue as the GN only supports a handful of 5Ghz channels, so set them accordingly in DD-WRT on my E3000...same result.
To rule out the router, I activated the 5Ghz wireless on my Virginmedia Superhub and what do you think happened?? Exactly the same as before. Everytime I tapped connect, there was no evidence of and attempt to connect to the network. I then tried the 5Ghz SSID on the E3000 and got the same result with the Superhub one dropping back to "disabled" as the OP noticed.
I'm trying to recall if the problem occured before or after the volume fix OTA but I can't really remember to be honest. I'm sterting to think that the handset is faulty as only a couple of people seem to be suffering with this issue...
---------- Post added at 09:50 PM ---------- Previous post was at 09:38 PM ----------
I Googled the issue again and discovered a post on Androids bug posting forum which seems to indicate it's a hardware fault:
http://code.google.com/p/android/issues/detail?id=23296
I think a trip back to Phones4U is in order for an exchange.
It's happened again!!
I have the same problem with the replacement handset as before. I had just been using 5Ghz, disconnected and when I tried to reconnect, it just sat there as if I hadn't selected "Connect". I've been looking around on various forums and I'm inclined to think that they just die after a while as there arer many other posts similar to this with lots of people trying saying the same as I (and the OP did). Mine has been fine for over 2 months and suddenly has ceased to work...Looks like a warranty replacement this time as P4U were kind enough to replace the handset in-store even though I was out of the 30 day exchange period as I had shown them this forum post indicating it was a known problem that other users were suffering...Technology always fails me in the end
..
Wi-Fi on the GN is horribly broken—you just need to accept it until the Android developers get their heads out their *sses and fix it. Using our Cisco enterprise-class access points, the GN cannot connect at 5GHz—though every other Wi-Fi device that supports 5GHz can. That said though, the GN CAN do 11n over 2.4GHz. Go into Settings, Wireless and Networks, Wi-Fi and tap on your SSID. This should show you your link speed and 72Mbps is as good as you’re going to get with a 20MHz channel and the GN hardware—mine shows 65Mbps and this is an 11n speed, albeit a slower one. From the configuration of our enterprise-class access points, 11g covers “6.0, 9.0, 12.0, 18.0, 24.0, 36.0, 48.0 and 54.0”—whereas 11n covers “m0-m15” (MCS index). The GN only supports m0-m7 and, currently, my GN is connecting at m6.
Hope this helps! At least a little.

[Q] Strange WiFi connection issue

This is a strange issue that I have not seen before. I was starting to have issues with my phone connecting to the wifi at the house. I decided to flash a clean rom today and hopefully that would fix the issue. I did a clean install and now my phone will only connect to the 5G band and not the 2.4GHz wifi band. I would like to connect to the 2.4ghz band but I get a message saying authentication error. I removed the connection and connected using the wps push button but when i do this it only sees the 5G. Any ideas what is going on and how I can correct it?
Do you see the same issue on the stock build ??
You are running what rom ??
Try the rooted stock build as a test. ..and if no change. ..reset the router and set up the connection on the device again. ..g
Have you tried turning off the power saver?
I suspect your router as the culprit but you can try going into the advance menu.
Hit *#0011#* hit menu then wifi menu.
I think you may even be able to choose the band? I think you can choose auto or manually pick 2.4 or 5ghz. Either way see if shutting off the power saver helps.

(Time And Relative Tarts In Space)
That is strange usally its the other way around...I have my dual band set up similar to yours..I named the 2.4 actually 2.4 and 5.0 same password..sometimes ill have to hit scan to show the 5ghz band...sounds stuiped..but make sure you click show password and make sure your entering rhe correct one..it may be so simple you may entered wrong password...or try changing the channel on the 2.4 ghz in rhe router setring to a different channel..mybe be a conflict..change it to channel 11..and reboot the router. ..
I have tried it on a stock rooted rom as well as CleanRom 3. Does the same. I have not tried a CM based rom to see if it only does it with the TW based rom's. I have checked the router and I don't see anything there that should cause the problem. I have 4 other android phones, and android tablet, and 1 iphone in the household and none of the others are having this issue. I have also noticed that it doesn't always say authentication error. Sometimes it says out of range even though I can be standing right beside the router. I am stumped.

Did you ever solve this? I'm having similar problem with my Note 2. I have a strong wifi signal incoming to the phone, but the transmission signal is very weak (verified using dd-wrt on the router and looking at client signal strength). My Note 2 has extremely poor strength.. ~10% where every other device on my network is ~50%. I've tried factory reset, turning off wifi power save mode.. not sure what else to try.
I am having a similar problem for the past couple months. My Note2 (ATT) with custom ROM won't connect to a 2.4 GHz wifi. No problem connecting to 5GHz wifi.
I saw an answer to this for a Sony Experia that the problem is with 802.11 mode and to change a file option gDotMode from 3 to either 1 or 2, but I haven't found a file with that option in it yet.
Same problem here, no 2.4 authentication unless the phone is very close to 2.4GHz AP.
Same problem here, no 2.4 authentication unless the phone is very close to 2.4GHz AP.
I have noticed that in some public networks i can connect with no trouble, (I guess now that they're 5.8GHz)
but not at home
Any solution? I am using a note 2 i317m with stock rom 4.3 from TELCEL mexico carrier

[Q] Wifi is connected but no traffic, WTF?

I thought at first my router was having issues, but that is not the case. I have confirmed zero router issues by using 3 laptops and 2 other phones (Samsung units) to connect to anything I want.
If I connect using my M8 (Verizon), it connects with no issue but I have no real internet connection. The signal strength is -40 so that is not the issue.
I have tried multiple restarts, multiple networks, and multiple SSID's. I even tried forcing it to 2.4 or 5 Ghz and nothing at all seems to work.
Is this a known issue? I am coming from a long line of Samsung stuff so I am not up to speed on the quirks with HTC stuff. Your assistance is appreciated!

Stock, custom ROM, etc?
This is a stock ROM with weaksauce root and nothing else.
Ok, so I just connected to the wifi at my office and it appears to be working just fine, but it took about 15 minutes form my phone to recognize that the network even existed.
I am pretty sure this phone is just a piece of crap. About 2 hours after my last post it started doing the same thing (at work). I just got home and did a 100% fresh reset of both my router and my phone to eliminate any possible configuration issues and it shows that it is connected on the phone, but the router is not seeing that it is connected... how the hell does that work?

Since you've determined its a piece of crap, sell it and get yourself a iPhone. Why bother trying to get it to work.
When you connect to your router what details does it give in the phone WiFi settings for that connection?
Also which router do you use?

[Q] Wifi issues

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?
Yep tried forgetting, re-adding the wifi spot and nothing.
I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks
Rob

Anyone else having WiFi randomly disconnect and reconnect?

I just got this phone yesterday and so far I just cannot get it to stay connected to my network. No other devices are having this problem. It basically just seems to constantly connect and disconnect from the wifi and also seems to constantly search for other connections as well. I've tried factory reset, cache clearing(which never works as it just red triangle error's me), reset the router, tried to change settings in phone itself but nothing seems to fix it and it's making it impossible to use at home. Anyone have any suggestions?
Same thing here. I went in and turned off all the wifi in battery power saving exclusions. Ain't been home long enough to try though.
I'm having this same issue! My prior daily (S9+) didn't have this issue, and my Pixel 2XL doesn't have this issue. I could be right next to the router and it still does this. Doesn't seem to matter if I'm at home, work, parents house, or a cafe, it still randomly loses connection. Same with my Gear S3. Just randomly loses connection. It's pretty annoying, and I hope they offer a software fix. Yes, I factory reset the phone and it still occurs.
I noticed this only with the 5 GHz band... I will contact LG about it today...
Yeah, I'm having the same issue. My router broadcasts both 2.4 GHz and 5 GHz on the same SSID. Last I'd heard, Android wouldn't connect to 5 GHz in that circumstance, and my G7 appears to continue that trend.
But it still disconnects from the network all the time.
Sadly I have the same issue. I have different SSID for 2.4 and 5Ghz band, and as devil_tear says it's fails only with the 5ghz band. I did a factory reset but issue stills there.
Did you found a fix for this issue?
Had the same problem. Solved by enabling wifi on the battery saving power exclusions in the battery menu.

Thanks a lot for this tip.
Had the same problem, was burning through my 4G data at a rate much faster than on my Google Pixel.
So far, adding wifi to the power saving exclusion has seemed to fix the issue. Thank you!
PS: Does any else find the wifi signal on this phone is weak?

Great suggestion
Tried the suggestion here for adding WiFi to exclusion. WiFi on 5ghz still disconnects and reconnects every few seconds. Only way to keep it connected is putting it on 2.4ghz.
Tried the suggestion with reboots, factory reset, adding WiFi to exclusion and then connecting to the network. My g7 will just not work with it.

Have seen this also, in my case it happens when I am a bit far from the router, it may be the router not having a strong stable connection so the phone see it doesn't have internet. In the points I experience that I have a 5Ghz connection of 0-2Mb but I have maybe 2 bars of connection. Share your opinions to try to understand the problems.

For me I would say it happens more if I have 2-3 bars but nonetheless it happens even 3ft away from the router eventually. what's odd is my note 5 stays connected, my computer, and other phone stay connected on the 5ghz band. All these devices are in the same location so I'm pretty dumbfounded especially considering this is a newer phone than the note 5 lol. I hope it can be fixed with an ota update

I have the same issues. I sent back the first phone for a replacement thinking it was the issue. When the second phone arrived it was working perfectly and then it happened again.
I noticed this happened after I took whatever software update was offered. I went as far to switch providers with different equipment (fibe to cable) but same result.
Made specific 2.4ghz SSID for LG G7 and no issues.
I've never seen this happen. And my laptop and LG are using the same 5 ghz signal.
I think I remember the G6 doing this though

Just came back from my dad's house and I know it's a short test, however he has an Archer a7 connected after his dedicated provided box. I wonder if that can fix the issue?
I have the same issue.
it connects to 2.4Ghz networks fine but the range is very limited when I move to another room wifi reception decreases a lot. However my wife`s S9+ and my oneplus 6 works fine.
Main problem is when I connect to 5Ghz network it starts disconnecting and reception is even worse than 2.4Ghz. S9 and Oneplus connection is still fine at 5Ghz
I tried to change the 5ghz channels on the router but no luck and I exclude the WIFI from battery saving apps still didn`t work.
I have to use 2.4Ghz and the reception is not as good as other phones
Wifi seems stable for me, except wifi calling. That would crash at connection or even mid-call sometimes. I'd have to reboot to make or receive another call. Some sort of server error. Turned off wifi calling and no issues yet. Didn't notice Ed it anyway since 4g is really strong here.
After the newest update on my phone, taken today Oct 4th, 2018/my random WiFi disconnects haven't been happening at all on 5ghz. Also, the signal is about 3 bars larger now in the same location it used to be dropping out constantly. Hopefully it stays this way.

I was coming in to report something similar. I've got the US T-Mo version and just got the G710TM10K update yesterday.
WiFi stability has massively improved. Disconnects are almost completely nonexistent now. I haven't noticed that the signal bar is behaving any differently, but that doesn't mean a whole lot. The update was fairly large (over 400 MB), so I could see new firmware playing a role.
Could anyone still on G710TM10G post their data from Software Info to check if the baseband has been updated? Here's mine from 10K:
Android Version: 8.0.0
Android Security Patch Level: September 1, 2018
Baseband Version: MPSS.AT.4.0.c2.9-00045-SDM845_GEN_PACK-1.160685.1.163435.1
Kernel Version: 4.9.65
Build Number: OPR1.170623.032
Configuration Version: 2.350001
