Wifi not working correctly - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello people of XDA!
I had my note 3 runnning on CM11, suddenly it wouldnt connect to my router 5ghz network anymore but it did fine on the 2.4GHZ i tought it was a CM11 bug so i restored back to TW now i can connect to the network but my Download speed is really slow (about 1-2 mbps compared to my laptop wich speedtests at 50 Mbps running the same wifi)
The question is: is my note broken (again) or what should i do ?

Great now i cant even connect to the 5GHZ network, if somone kind would help me i would be thankfull!

(You havent changed any settings in your router lately ? )
You tried rebooting ?
If wifi isnt working at all one of your last chances might be a backup + wipe system/clean flash of current ROM.

Use wifi anyalyzer on the play store, and see what channels other routers are using, if they are on the same as yours and there is an empty spot somewhere, try changing your routers channel to a free one.
I have had many issues in the past due to this, damn neighbours! Haha
This may not even help, worth a try.

Well im the only 5ghz network here nearby according to Wifi analyzer, strangely i can connect to the 5GHZ via wifi analyzer but after i exit the app it disconnects... Weird...

Could be the location settings under Google settings, caused me problems with glitchy internet in the past. Switched it to gps only one time and after that to desired setting and it solved the issue for me.
Hope it helps.

I had the same problem. I think it's being caused by the wifi trying to autoconnect to a remembered AP in range. I just had my phone "Forget" the network I knew it was trying to connect to (my home network) and it worked.

really i am almost to downgrade to cm6.1 were there i have no trouble to wif and gps.
Today i saw the network and try to connect and fail... and then i connect and in the middle of using ebuddy disappear. then could not connect anymore.
Hi,
Cm7 is quiet weak with wifi. Meaning the signal strentgh in cm7 is less like e.g. on b 0.8.4 maybe flashing another radio helps.

I flash another radio and didn't work. Clear data, cache and dalvik. Nothing. Só i give a trie on nightly #58. Did a clean install and it worked. Went to the coffee shop and detect the wifi and could connect with a good signal. Tomorrow i'm going to my brother's house where i had the same problem. Then i will report if it's ok or not.
Thanks.

I went to the coffee shop and again... i dont see the wifi. Yesterday worked... today cant find again. I love cm7, but like this is not very good. Well, im going to downgrade. I cant find any real solution.

have you tried changing channels on wifi settings-->advanced-->regulatory domain? just a shot though. it worked for me on the nightlies. on latest cm7 stable though, i haven't need to change it...
did you use any other wifi tool than the cm7 internal one? Wifi analyser or similar apps may watch out for more ssid than CM7 itself
maybe the wifi channel is out of range, meaning cannel 11 or higher. Then change the channel settings in android settings

[Q] Nexus 4 Wi-Fi issues.

First - Hi all, long time reader but this is the first time I've needed to start a thread - so sorry about my first post being a problem/Q!
I've not had my Nexus 4 long, but have got some pretty annoying Wi-Fi issues. I've searched for answers but it seems that people have different Wi-Fi problems and I just wanted to see whether my issue was a common one and, if so, is there a fix on the horizon?
My issue is that I can connect to some routers but not to others (work, home, most open networks)... when I connect it simply says "saved, secured with WPA/WPA2" but wont then connect.
Phones running stock 4.2.1 with franco kernel r28 and the things I have tried are:
Resetting routers
Assigning static IP address
Wi-Fi direct from my Nexus 7
Cleared cache from recovery
changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
Flashed new kernel
Very frustrating and because of my signal the lack of Wi-Fi has made me go back to my old phone while I wait for a fix... which connects perfectly to the networks (S3 running CM 10.1)
Is this a 4.2.1 issue - as seems to be the consensus with other Wi-Fi issues or possibly a hardware issue?
Thanks for any info!
There's one fix you've not tried which might work for you (it didn't for me). You would have to be rooted though, which is going to system/etc/dhcpcd and changing the permission on dhcpcd-run-hooks to read and execute from "others". This help some people out but turns out for me that my router isn't compatible with my phone. (DSL-2780).
I've noticed that some of the mobile devices(eg iPhone 3gs, SGS2) are quite sensitive to wireless channel which your router/ap broadcast on.
Try manually switch to channel 6 or 8 that solved my issue - I don't believe in incompatible routers usually problems are related to config.
It is more complicated with an access to the public WiFi as you can not modify the setup.

Just to update.
I've now tried this and still can't connect to the affected Wi-Fi networks, probably going to have to wait for 4.2.2 to see if that fixes it...
I had troubles connecting to my wifi network here in my house, which worked pretty good with my galaxy nexus, what i did and worked was deactivating the option "avoid poor connections" in wifi advanced settings, you should give this a try
Fixed it for me

Thanks Chad, it was driving me crazy the constant data drops I had when trying to listen to streamed audio in XiiaLive Pro. Which worked flawlessly with my old HTC Desire.
Did as you said, and perfect now.

I too have wifi issues with my N4. We have several phones at home - an HTC Aria and believe it or not the SGS1, SGS2 and SGS3!
All of them connect with no problems. My brand new N4 will see the router but refuses to connect until I toggle wifi on/of serveral times in succession, sometimes 6-8 times!
I have avoid poor wifi disabled but it does not help
I really hope El Goog fixes this asap as it is very frustrating.
I've had this issue forever. Android phones hate low or overcrowded signal. Though my nexus 7 always works fine. Makes me think it is the lack of WiFi antenna strength

WiFi Direct not working?+ WiFi download speed issue

I want to know what are the procedures for wifi direct to work...Yesterday i was trying to receive a file from my friend who owns a s3....i opened wifi direct...connected the 2 phones...and then he selected the files and clicked on share..then selected via wifi direct...but every time we try this step it fails...even worse happens when i try to send something..i cant even see wifi direct option in "share via" menu...
Please if u guys could help me out here..
And i have another issue too...my wifi seems to be pretty bad...I have tried many ways to work it out..nothing works...most importanty...the download speed is too damn low...i dnt knw why...all my other phones work good...
Please Help...
P.S im not rooted

Stock Android does not support WiFi direct. It uses bluetooth to transfer. I would try the Superbeam app (You have to install it on both phones). Are your other phones working on the 5GHz WiFi band? If so, what channel is your router broadcasting at? Some people have issues with the Nexus 4 not connecting to bands 12 and 13 (if my memory is correct), but not all (My 211k Nexus is fine). Are you running stock? If not, what ROM and kernel are you running? Have you tried to disable WiFi optimization (Settings>WiFi>Menu button>Advanced>WiFi Optimization)?

I recently moved to another location and found out Nexus having hard time to connect to Google through Wifi(grey wifi bar appears often). Surfing internet is also dramatically slower than before. I do not know if it is Google I/O related issue (namely software issue) or router (namely hardware issue)?
All my PCs and another Samsung Android phone work fine with the new router. What's happening?

[Q] help wifi won't connect after upgrading to 4.3

Hello,
I'm hoping someone can suggest a fix, yesterday I upgraded to 4.3 using adb. I'm fully stock not rooted. today for some reason it won't connect to my home network. It's a cisco e2500 router and its on the 5ghz band. I tried setting different channels, turned off optimization....
what gives???

Seems like there is an issue with your router. Did you change anything recently in the router setting? Try restarting the router.

I had immediate problems with Wi-Fi after updating as well, I don't know what the new radio features but it turned out that a firmware update to my router had everything running smooth as butter again, actually better (a lot more reliable–YouTube app actually appears to buffer noticeably less and not break up, for example, downloads also initiate and complete more solidly) than it was under 4.2.2

I have the same problem, since the update to 4.3 does not connect to the 5Ghz band.
I'm back to 4.2.2 and not connect, does it damage my hardware nexus 4?

I'm using an Asus AC66U at home and N66U at my office with no 5ghz connectivity issues.
Here's some things that might help you troubleshoot. Start by disabling the "avoid poor connections" feature in WiFi options. Install inssider or similar WiFi scanner to see if there is interference for your specific router config. Try removing the WiFi connection from your phone and reconfiguring.

Hi,
It's strange I have a similar problem. After upgrading to 4.3 my 5ghz connection came to a crawl. We are talking about 1.2-1.6 Mbps. But the 2.4 ghz was fine (35 Mpbs). Once I downgraded, re-writing the "radio" file, then the 5ghz connect was blazing fast again (50 Mbps). I'm convinced this has to do with the "radio" update, but I'm not sure what exactly.
Any suggestions? Currently I'm back on 4.2.2 as wifi speeds (PA rom) make more sense right now.
Thanks in advance!

I tried all of the above, every combination, reset my router, there are no other 5ghz overlapping networks, at this point it is something to do with my install. I wonder if a factory wipe would help...
That's my exact setup (E2500' did you set the Wi-Fi frequency band to 5GHz only on the N4 and give the band a different SSID from the 2.4 GHz network?)! Try forgetting the current connection and setting it up again.

I'm pretty sure it's not your router setup and the radio upgrade, as I mentioned earlier. Try going back to stock 4.2.2 and see if you can connect

If it were the radio software specifically, then logically 5ghz would be broken for everybody, which is not the case. Perhaps the issue is device data specific... There has to be a better solution than staying on 4.2.2.

I have with wifi problems too, but with 4.3 and 4.2.2 version. At home everything works fine, but at work phone connect to router, but no Internet (internet work only 1-2s). Other devises with this router works fine!
I have even a different issue. The phone is stuck at Obtaining IP Adress every time now. I downgraded to 4.2.2 and it's still doing the same thing. It does work if connected to a different router, but not to my main one. I haven't changed any router settings either.

[Q] Wifi won't stay connected.

Is anyone else having issues with Wifi not staying connected? For example, it'll keep dropping out from my router every 3 minutes or so. When it drops out, the 3G will enable for a few seconds but then it will connect back to the router.
Is anyone else having this issue? What did you do to fix it?

Are you rooted? Have you done any mods? Perhaps you should check the advanced settings in the WiFi option
Sent from my GT-I9505 using xda premium
Hi,
No I'm not rooted. No mods at all. 100% stock firmware. I have checked the Advanced Wifi options but can't see anything wrong.
Just to mention, I did at first think it might have been a fault with the phone so I got the phone swapped out with another brand new device however the problem still persists.
I have a similar problem on a i9505 running the latest CM 10.2 nightly.
Some 2.4GHz networks are fine, others behave as you describe.
The one 5GHz network to which I have access has recently started to misbehave; the phone connects properly and works for about 2 minutes, after which I lose all connectivity (I can't even ping the router) yet the wifi indicator remains blue. Turning wifi off and on again gives me another 2 minutes. This goes on until I give up and switch to 2.4GHz.
Of course, I have no idea what is causing this. I've tried various channels on the router, as well as rebooting it.
Does this happen to all routers (I assume you use other routers somewhere else), or it just happen to this router only? Is this case, you may want to check the router itself.
Sent from my GT-I9500 using xda app-developers app
Frequent disconnections occur on all 2.4GHz networks. As for the 5GHz, I've only got access to one router on which to test it.

I've only tested it on my router.
As I say, I thought the phone was faulty so I swapped it out but the one I swapped it out with had the exact same issue.

A couple of things concern me about this method though. Do we know what setting that mode to OFF actually does? I've heard reports that the phone gets quite hot and battery drains.

Or maybe Your are a doesntt support Very well Your fréquences for match Your mobile?
Have you try to make a Fullwipe? For put tint everything restant as when you have buy it?
You will be on a custom rom with ni mldem update i dont say but chère..
WiFi still disconnecting even on 3rd device...
Wiping /system and flashing a newer nightly fixed the 2.4 GHz problem, but 5GHz is still dodgy. It's not the (Netgear) router as I have a couple of other Cyanogenmod devices which operate without any problem.
Perhaps I should start another thread as this may well be something different from what is affecting the op's device.
