Wifi Dropping on Custom Roms - Galaxy Note 10.1 Q&A, Help & Troubleshooting

So I just bought one of these Gnotes and I had trouble with the wifi right away: always dropping on DHCP. Set it to static and it seems to be better but not what I would say great still seems to stutter at times. Is this some setting in Samsung's config file or a bad wifi card/adapter. Router is not the issue running Buffalo WZN-HP 300 with DD-WRT all other devices connect fine. Question is has anyone noticed wifi improvements when switching to CM or another custom ROM vs Samnsung Orig firmware?

OK, testing while tethered to my phone's hotspot, the drops ceased so it appears that they ARE related to my home network...damn

Well read some where setting wireless to just "n" helped and it appears it did. Will continue to test and report. I reflashed router w latest ddwrt and that didnt fix tho.

Well apparently a reflash of router firmware and a factory data reset have solved the problem for now...reset showed most improvement but I did it twice bc first time did nothing...go figure

Wifi errors

OK so on my open network at home o can connect but then I lose internet connectivity after about 5 minutes. Recently today though when I go to shut off wifi and bring it back on, it just reads error and won't let me check it back on or off. I then power cycle the phone and I'm back to square one with the 5 minute disconnect. Wtf

It may not be your phone.
I had the same issue but I reset and reconfigured my Cisco router
Renamed my network and phone connected within seconds and I haven't had any issues since.
Try connecting to a different wifi network and see how well it connects.

Same thing happened to me at home.
To resolve it I had to reboot my Wireless Router at home, then I was able to connect.

wifi is flakey on mine as well. Also google market will say "no connection" while other apps connect to the internet just fine.
So far (knock on wood) my wifi is great.
Except for that one time I had to reboot my wifi.

I replaced my router today and my wifi issues went away. I'm sad to find out the Atrix 2 doesn't support 5ghz wireless N
This is a motorola bug. It exists on the Atrix 2, Droid 1, Droid X, and Droid X 2.
It has something to do with the method the wireless radio in the phones notifies the AP that it is going into low power standby. So far I've been unable to determine the EXACT reason that it does this, but have a feeling its related to using WPA/WPA2 and sending the LPN to the AP with that enabled.
I'm trying to figure it out, and if any one else experiencing problems with wifi where it drops connectivity after 2-5 minutes, please let me know the following info:
Length of SSID
Brand of Router / model.
Encryption type: EG, WPA2/CCMP (CCMP=AES on some devices)
length of encryption key.
I'm going to try and find a way to fix this at the router, provided the settings are available.
Ssid is the same as router name WRT330N. No encryption. Got my new skyrocket no more wifi issues

I am experiencing exactly what you described, every time I connect to WPA2 network at my college I experience weird problems. For example when I stream music with GoogleMusic I can barely go through one song. On the other hand I have no problems at my home where I also use WPA2. The most confusing thing is that my phone acts weird on unsecured networks too.
Do you think this is a software issue ?
For those who are seeing the poor WiFi connections that lock up after a few minutes...
Go into your router settings and disable WMM.
I am told (by a reliable source) that the problem resides in some T.I. drivers commonly used in Moto phones and it's exacerbated by overly strict code in many routers.
In any event, I was suffering terribly unstable WiFi connections that would lock up every few minutes. As soon as I disabled WMM on the router, everything started working cleanly and has remained that way.

Thanks for the info. What should we do if we use wifi in a university or any other place where you can not change router settings? Do you think Cm7/Cm9 will remedy the problem?

[Q] Emancipation WiFi issues?

Has anyone else tried connecting to an invisible wifi network with Emancipation? I had been having wifi issues with Revelation constantly dropping and reconnecting to wifi so I made the switch to emancipation and it won't connect to the network at all. If I make the network visible it connects.
Before flashing I used Heimdall One-click Back-To-Stock UCLB3.

The school where I teach has an invisible access point and I have no issues connecting. What type of router are you using?
DLink DGL-4500
I sometimes have to toggle wifi off and on again. it shows connected, but there is no data getting through.
I have found just turning the power off then back on for both my modem and wireless router...resets all...with two PC and 5 phones...that helps me.

I'll give that a try, we've had some pretty wicked weather lately.
I finally got it to connect. However, it's started doing the same thing again dropping and reconnecting until it eventually just shows the wifi signal but doesn't appear to be connected or transferring data through it.

If you guys are having trouble connecting on to an invisible network,
Zen has noted that the keyboard, after a few flash, can insert additional characters. I noted these odd behaviors when using swype.
It is not as prevalent on android or stock samsung kb.
If you are try to connect, change the kb to sammy's or android.
If you have connected and dropping or can't connect, I would recommend trying my wifi-fix script in cwm. I'm curious to see if it works.
Power the router off and on is also a good idea. some routers are buggy or just need a power on/off.

Mine finally worked after toggling bluetooth, gps and airplane mode on and off.
I did notice the keyboard leaving extra spaces but as I caught it don't suspect that was the issue.
I've been using this router set up as is for years and have only recently started having the connectivity problems with phones I've put recent releases of revelation, emancipation or Zeus on. For some reason lately my cell signal at my apt has dropped drastically (majority of the time barely 1 bar; would get 3-4 bars when I moved in December) so not having wifi makes everything a real pain. I almost think att has black listed my account or something. I've tried multiple modems but problems present with each one.
I would gladly try your script do you have a link?

On an unrelated note how does one edit the APN in emancipation?

Wifi issues since ics update

I don't know if anyone else is having this issue or not but since I updated to ics UCLD2 and UCLE2 on both updates I seem to drop wifi connection every few minutes. Every few minutes I see a box come up that says connected to belkin. I know its actually dropping it because at times I will look up at the status bar and the wifi symbol that shows your connected won't be there then it will come back on and say connected to belkin. Its something in the phone because all the other devices on wifi in the house isn't having this problem. Anyone having or have had this problem? Any solutions? My wifi is set to never sleep and I've tried several wifi fix apps on the market and I've tried changing wifi channels still no luck..

It done it all the time on the previous leak ucld2. I thought the problem was fixed with this leak because it did fine for a couple of days it only done it a few times. But now its gets worse everyday. As long as I'm in the living room where the router is it only drops every now and then but in my bedroom away from the router it does it every few minutes....

The only thing I could suggest is flashing romracers radio he pulled from the leak. Flash it once, wait a minute, then flash it again and wait 30 seconds and reboot. It may help, it may not.
OK I don't why but I read somewhere that the skyrocket don't deal with wpa and psk security to good so I removed the security off my wifi connection and renamed it something other than belkin. I did this about oh 4 hours ago and I have not lost connection once which is great but now my wifi is wide open with no security. Guess Ill have to put my monitor on it that will let me know if more than 5 devices are connected....

Are you able to run security on your home wifi or do you just have it open? My wifi works better and faster than ever with not one disconnect as long as there is no security key to logon to the wifi. Its crazy I've never had this problem with any other device. And none of our other phones which include captivate infuse HTC status or our friends iPhone or laptops does it only my phone and only since the Android 4.0 upgrade. I flashed back to my nanadroid gingerbread backup earlier and it connected with no problems with the security on but soon as I flash back to ics is drops every few minutes until I turn the security off. So I tried the gingerbread modem with the ics and still the same drops every few minutes only with the security on. So I don't know I'm just leaving my security off and maybe when the official update comes out it will have a fix...

Im not actually at home, I am running on hotel wifi which is not secure. So I can't test that for you.
My SR has had near flawless wifi in multiple networks / security types, on 2.3.5 /6 GB and on UCLE2. The 1 exception is my home router, where it would make the secure connection, but the broadband DNS server seems to block its data connection. This affected Cappy also, resolved both with static settings. The only wifi adapters I've seen needing open settings either needed newer drivers, or were damaged ones needing replacement. One workaround for your 5 at home is a MAC filtering list.
As for wifi issues,
the only serious wifi issues I had was when using Facebook. It simply could not hold a connection. Browser, any other apps all seemed to work fine.

My wifi router is a belkin and I just recently purchased it a couple of months ago so do you think it could be bad? Also when I go to my mother in laws she has a AT&T 2 wire wireless router with security on it and my phone does it there to. None of our other phones does this and also since I posted yesterday a friend come over with a galaxy s2 not skyrocket and it connected as well with no problems. Our router is set to dynamic connection. We have DSL which is a PPOE but when I set the router to PPOE and put in the user name and password it just connecting and sticks there so I changed back to dynamic...

Given the other phones work well it seems like a fault in your phone, not the routers. One troubleshoot/workaround is to enter appropriate static IP settings as detailed in posts 1 & 7 here. That will either stabilize it or show you need to reimage the phone with full wipes to test further. You can screenshot most of the settings you need using the Ipconfig app by Mankind, during a good connection. Just take care to choose a static address outside of the router's assignable DHCP range, to avoid conflicts.
The same issue exists on the recently rolled out official ICS update for the Galaxy Note, I'm having this problem with stock radio and no root.

As long as I'm connected to an open wifi connection it works just fine but if I secure it it constantly disconnects. I'm starting to wonder if its a Samsung problem now because my wife's Samsung infuse on gingerbread is doing the same thing. And its not just my home wifi it does it at friends house with secure wifi and at mother in laws to with secure connection but never on any open connection. Um my daughters two HTC phones does not have this problem so I'm starting to think maybe its a Samsung problem. I don't think its an android problem cause both the gingerbread phone and my ics phone is doing the same thing. If it is android its something in gingerbread that carried over to ics

Had same problem
I had the same issue , went from 2.3.6 Gingerbread to the ICS UCLE2 leak and my wi-fi would turn on and off , so I just started from scratch went back to 2.3.4 via Odin , updated to 2.3.6 and flashed back to the UCLE2 leak via Odin and now it's working fine , I kinda figured it was a glitch in the software somewhere , from where I had changed rom's so many time's , and apparently it was , hope this was helpful.

[Q] Wifi Problems

Hi,
Starting to lose my patience with this device now. Such as shame that this lovely piece of hardware is strangled by poor software. I've already put the device on ebay and withdrawn it because its so slinky and I really want the issue to be sorted. I have no option but to go with the ipad mini at this rate, it just works!
Using odin I've successfully upgraded to ICS with P6800DXLP8_P6800OLBLP7_P6800DXLP7_HOME.tar and XXLQ1_OXALQ1_ATO My wifi keeps dropping out, ive tried it on three different routers etc and still the same issue. Tried CM10 and that reboots on me. Ideally i want a stock rom that works without any niggles on my Euro p6800. Any ideas, i'm really trying to make Android work for me, ive searched the forums like a good boy but no real answers anywhere.
:cyclops:
I can't help but thinking... if you are fed up with the Sammy device, why not switch to something that is completely open, like the Nexus 7, instead of a closed ecosystem like Apple's? Seems like there are other (better) choices out there than the iPad mini.
I'm sorry you're having troubles. Please feel free to give me your tablet. I could always use two!
Barring that, here is what I would suggest that has worked for me:
I have always had "advanced WiFi lock" from the play store, and it appears to have improved WiFi performance even when I had ICS.
I had locerra's cyanogen 10 ROM for a spell and really liked it. I then did some research in the development section and found Daniel HK's Paranoid Android ROM v. 2.55 and have enjoyed it even more. WiFi performance has been consistent and stable on both custom. roms.
Do some research and have a go at it.
If not, i can give you my address as I am currently living in Mexico and you can ship it to me!
I didn't experience any wifi issues at all until today. I'm staying with a friend for the week in Canada, and wifi k3ps dropping out. It seems that only a restart will solve the issue, and the network then falls out of range(even though I'm next door to the router). I'll give the app mentioned a try.... But any other thoughts please let us know! I'm on the leaked ics rom from Open Austria, rooted.
Update: "Advanced wifi lock" app has solved the issue, thanks! But we shouldn't really need to download the app.. Any ideas of how to solve such issues natively?

Correction, sadly the app didn't solve the issue.... Still having intermittent wife but HTC is connected constantly.
Sent from my GT-P6800 using xda app-developers app
Ensure you don't have BOTH 2.4 GHz & 5 GHz enabled on your router at the same time.
Use one or the other.
After disabling 2.4 GHz band, and using 5 GHz only on my Billion router, my device (P6810) had no wifi drop-out issue. Same if I use only 2.4 Ghz band only.
Hope it helps.......
BTW, I would suggest LP8, such as my SkyHigh ROM, having "fixed" wifi issue for most........ But try the above first

Did you fix your issue in the end? I've tried changing settings on the Cisco Valet router to operate in just one wavelength but there is no such option... I guess it must be a old router. The wifi lock app didn't make much difference either unfortunately.

Thanks, The firmware on my mate's Cisco router was out of date, wifi connection much better but it still cuts out and appears to only reconnect if I restart. Even a "quick reboot" from within Rom Toolbox Pro doesn't reconnect. Annoying issue... It even cuts out midway through a skype call with my wife (but no issues on mates ipad or my htc) Also no issue with my wifi connection back in the uk. Very weird. Any further ideas appreciated!

Just wondering of the connection is secured? Does it cut out on open connection?
If secured, did you restore wifi settings with any particular app (ie. Titanium)? If so, you could try delete/forget wifi connection and manually enter the password instead
Or, delete/forget wifi connection in settings and restore with titanium backup. You usually have choice of "101" or "XML", try one then the other, reboot each time after restore.
Edit: if you have another device to set up a wifi hotspot, open and secured, and test?

It's a secure network, but i've tried forgetting the ssid and then reconnecting, but it makes no difference... Still patchy connection. I don't want to make the network open as it's my mate's network not mine.
I downloaded an app called "wifi manager" and it seems to be working 60% of the time, which is good enough for the moment. When I get back home to my own wifi network I expect no connection problems as it was working fine when I left last week probably the issues were due to my mates awful Cisco router and not the GTab!

I think it's the WiFi driver in the version of your ROM.
There is no reason you should be having to amend settings on a router because in most instances, you will not have access to a,ending the router.
I'm currently living in Mexico and I'm dependent on several WiFi access points around town and intermittent WiFi where I live. I can safely assume that the technology isn't the latest and greatest down here and I don't control any of those settings.
I am not experiencing the problems you are describing.
I think you're right, it is the wifi driver. I've just tried connecting to the open wifi network at Toronto airport, which connects fine on my htc, but i need to restart my GTab in order to connect to it. I'm running an official Samsung ics rom from the European carrier, Open Austria, (downloaded from samobile.com)... These issues only started when I left the UK and arrived in Canada. I'm wondering if the 3g roaming has some part to play in the error. Anyway.. I will try again when I get home, but anticipating issues.... How would I fix this? Do I have to reinstall the rom and all my apps?! (hope not, as I have this baby set up just perfect )

Maybe I overlooked it, but what is your current firmware?
Sent from my GT-P6810 using xda premium
Current firmware is the official ics from Samsung, build number Imm76d.xxlq2
Now I'm back home and wifi connects perfectly. I do suspect an issue of using wifi when roaming, but will keep an eye on it next time I go abroad again and post back if it happens again.

Ah, that says it all...
Check my comments about LP8 firmware mentioned in my first post here..... way down the bottom Was obviously missed. Posts after that, I assumed you had, since you didn't comment about it.
There is also a thread relating to the problem and the subsequentLP8 fix.
Either flash SkyHigh ROM (P6800 DXLP8) or official DXLP8.
Whether just flashing the kernel from DXLP8 firmware world do the trick, not sure, as I have a P6810. But as I said, flashing the firmware package helped most out with the "wifi bug"
Do you have root and custom recovery?

Is there anything wrong with this ROM or could anybody recommend a fix or alternate ROM?
Thanks and Regards..
Possible solution to WIFI problems?
I have had major problems with WIFI in my 7.7. The Austrian ICS has dropped connections, went totally berserk in some locations and stopped working unless rebooted.
I have now diagnosed (I believe) that the reason is the use of channel 12 in any WIFI router. If the router does not use 12 there seems to be no problems. At home I can configure my router not to use 12 and after that I have had no problems. There seems to be some kind of conflict or the Tab is faulty in that sense.
I do not know if this can be generalized, but at least for me it worked.
Yes I had the same problem with band number.... My friend's router that my tablet had an intermittent connection with, was on band 11. As soon as I got back home to my router in the uk (which uses band 6) My wifi connection problems disappeared.

Yes I Can say after doing alot of reading i realised its the chanel.
im using locked chanel 5 and seems much better..also wifi connection manager from play store.
still not the greatest and low signal even in same room to router but working i suppose.
Just funny how my S3 has a much stronger signal compared to the 6800 every wifi ive ever used.
Would be good if somehow the wifi drivers from S3 could be used somehow?

Need help please. WiFi problems, can't find an answer anywhere...

Boy... I hope someone can help me out here. I have been searching for weeks with no luck. I have been having an issue with my stock 4.2.2 p5113 Tab 2 10.1 unrooted. I can't get it to find my home network. I can see my neighbors, even took it down to Arbys and was able to connect to their WiFi with no problems... Just can't connect or even see mine.
I have an Asus rt-n66r router. Have tried every channel and different frequencies. Changed every setting one at a time to see if it worked and nothing. Well... I take that back. Last night I turned off encryption and it popped up shortly... But went back away. When I go into advanced it shows the Mac address but IP says unavailable. I set up a static IP and that didn't help. I have reset the tab and router and even factory reset the router to no avail. It just doesn't make sense. Got this router back in March and its worked fine until now. Nothing has changed except me recently resetting the router to try and fix this. I have done everything I can think of but still can't see my own home WiFi. Everything else connects fine. Galaxy note 2, HP laptop on windows 8, smart TV, smart bluray, iPhone 5c, etc and everything else connects. Have even tried turning a few of them off to see if that helped but still nothing...
I really hope someone can help me. Had this thing for 2 years next month and it has always worked but at this point I feel like throwing it out the window LOL.

Also use WPA2 encryption. Have tried just WPA and WEP push button but wouldn't find it still. And tried turning off encryption again and still not seeing my WiFi. Wanted to add that...

Is this the only wifi device you own?
If you own another wifi device, does it see your wifi network?

I tried every channel and none of them helped. Did reboot the router and changed everything and still not showing...

No... Everything else works and shows the network. Have laptops, a windows tablet, an iPhone, a smart TV and blu ray and some galaxy note 2 phones and everything else works flawlessly. This galaxy tab 2 did and all the sudden can't see my home WiFi. Can see the neighbors, can see my TV sync and even worked when I took it to the local Arbys and used their WiFi. Only none it can't see is my router. I've only had the router since march. It cost about 150 bucks... Figured it would be decent... And it has except this one issue now...

If a factory reset doesn't do it then your tablet is bonkers. If you scroll down to the bottom of list of networks is your network showing? Maybe it has (forgot ) your network?

I went ahead and rooted and put on the slimbean ROM and still issue persists. So today I hooked up an old 15 dollar router I had from micro center and guess what? It showed up. So I factory reset my good Asus router and hook it all back up and still won't find it. I'm at a loss. Everything else in the house is connecting to that router no problem. Its some issue between this tab and this router... Only thing I dont get is why it worked before no problem and out of the blue it stopped connecting to the router without anything changing. I've been at this now for the past 24 hours pretty much non stop and I can't figure out what's wrong...

Can you see your Asus router on the Tab WiFi networks at all? Is it at the very bottom saying "not in range" ?
Long press on it, if there you'll get option to "forget network" or "modify" / modify. If you don't see it them it's forgotten, try add new network,.
Pp.
No... It doesn't show up at all. I forgot it a long time ago. I do see my TV sync for the remote control and I see numerous neighbors wifi names come up... But not my Asus router LOL. Its just so frustrating especially after what I did today and could see the cheap Tenda WiFi router from micro center that I don't wish to use anymore because its old and out of date. I really am about to pull out my hair lol

By "forgetting" a network you eliminate it from your list of networks, you then have to add it again as a new network. Could this be the case?
Images are examples of forgetting networks.
Pp.
No.. I understand what you mean. When I 'forget' a network, say on my phone, it will pop back up and I will have to click on it to connect to it. My home and guest WiFi names are no where on there. I scan and scan and they never show back up...

That's weird! I think you should consider rooting and installing a custom ROM, maybe a stock rooted ROM. I have Android Andi's CM11 4.4.4 KK running on my P5113 and it runs great. I suggested custom rooted if want to use the TV remote app, if not you should try CM11.
Pp.
Do you have a link to that by any chance. I am new to this. I did root and use the slimbean ROM... And tried to use slimkat but I couldn't get it to work. I think it was my version of CWM I think... Thanks for all the help

Op says stock /unrooted so only way to go to a different kernel would be to root and flash custom rom, and that will probably fix the issue. .
Pp.
Oh I did root and have flashed 2 Roms so far and neither have helped. Took the tablet down to McDonalds today and it was able to connect. But then went to a friend D's house, my phone connected to his WiFi but the tablet didn't see it. Seen his neighbors, but not his. So I am really lost at this point...
