Wifi keeps dropping off - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Hi, I am running on the ICS 4.0.4 build LQ1. Recently my wifi keeps dropping off. I have to keep turning off n on to connect back and it only lasts for a few seconds. Anyone had this issue?

Anyone in ICS ). Or a (bad) Huawei router. Jokes aside, try to fix permissions via Rom Manager and be sure that you have only one remembered wifi network. It's strange, but Samsung ICS "connection manager" disconnect from active wifi connection and jumps on the other(s). And not returning back...Or, better, try a newest custom ROM - if you still want "stock" appearance can use singha rom you can taste JB in Paranoid Android. Both higly recommended. Hope it helps!
PS. check also wifi router and set the wifi to a fixed (non-overlapping) channel - 5 for example.

[Q] Wifi signal?
Does anyone get a weak wifi signal with their Nexus S? Whenever I connect to my at home wifi I never get full bars and something I'll just randomly lose signal. Also it seems to go pretty slow. I used to have the Mytouch4G and it work flawlessly with the wifi. Anyone else having this problem?

OMG yesss I do.
Just about a room away I loose signal, almost completely. = 0
IDK, but I see more flaws every day that passes
Mine's been working fine over Wi-Fi. I'm pretty glad it does too, because my only data option with it is Wi-Fi..

Wifi has been working great for me. It reconnects automatically and doesn't drop. The signal seems on par with my nexus one.
Speed wise, is it on par with the 3G network?
[Q] Wifi does not work anymore after rooting :(
So, I unlocked my Android 2.3.1 and rooted it ... But if I click on wifi so I could connect to my modem it says Error and wont even search or anything. I tried reseting too but still no luck .. What is the problem and how to fix this ??
That's odd, I didn't have any issues with wifi as I connected to Android Market to downloaded ROM Manager during my rooting process earlier. Have you tried flashing a custom ROM on your device to see if it'll fix it?
No I didnt, would that work? .. A friend told me to install a new "kernel" but I dont want to overwhelm my android with custom made kernels .
your problem is you used one of the quick methods of rooting your phone, which used a kernel that wasn't from the exact rom you have.
if your on stock 2.3.1, you will need the stock 2.3.1 boot.img, and then you'll need to root it manually the long way via adb command line. search the nexus s development section for how-to's. they are all there.
i too had this problem, had to install MoDaCo ROM to fix it, but i dont regret rooting, i now have custom rom and over clocked cpu on the nexus s
you have two options, either to flash NANDROID backup to un-root and return to stock or install a custom ROM, i choose MoDaCo bcoz of its UI, it looks and feels just like the stock one.

Yes, that's the point of MoDaCo roms, to make minimal changes to the look and feel of the phone, but to improve performance with his custom optimizations.

Hi Guys,
I was able to connect to my wifi network for a day. I am using windows 7 machine as hotspot with connectify. From second day I am unable to connect to any wifi network. I did factory reset my nexus s but no results . Can some one help me how to solve this issue?
Observations:
*when i use static ip, It shows connected but the bars are in white instead of green color and i am unable to browse.
*When i use dynamic ip I am unable to connect to wifi. It shows obtaining Ip and never connects.
*In connectify when I was able to connect to wifi the device is shown with an android device name. but now the device is shown as unknown.
Sorry for my bad english, I m not a native english speaker.
[Q] Nexus S Wifi Settings - force close
Hi all,
Just got a new Nexus S - all was well at home. Took it to work today and noticed something very odd. It was fine until entering the wifi settings menu - at which point it dramatically slowed down. I got two 'not responding,close or wait' messages before being able to join the network.... all other settings are fine - just the wifi area.
Weird - wondering what could cause this... too many wifi networks broadcasting (am in middle of London)...?
Anyone seen anything similar?

Too many WiFi around you shouldn't cause that.
Try rebooting and setting again if you haven't already.
Hmmm - rebooted and still have the same issue. At home, or even a block away from the office it all works fine. But in the office itself, although it connects and uses the wifi fine, the settings page is VERY slow to load and gives me the wait/force close message.
Out of interest - I also have 'wifi analyser' from the marketplace. This too is very slow and unresponsive when in the office.
So - it is definately something to do with the wifi here.... but have not got a clue what. Before I join the wifi, or when I am physically somewhere else it all works fine.
Wifi is WPA-TKIP, the key is a very long jumble of letters but surely that is not an issue.
Strange eh!!!

[Q] Possible WiFi problem?
Hi there, just bought a Nexus S, also used to have Nexus One.
The thing is for some wireless networks even though I enter the password correctly, it says connected and still there is no connection at all. (I mean browser tries to connect but at the end it says page could not be found) I even tried with an ad-hoc network that I created with my laptop but still the problem exists.
At home I'm able to my network without a problem. The type of network I'm trying to connect is: WPA2 Personal with AES. Is there any known issue about AES at Android system? Afaik there is no way to change the encryption used right?
this might actually not be a nexus S issue.
some modems/switches/routers are configured to block certain devices/applications/package's
we have a modem and router with both wifi.
but my psp/nDS cant connect to the modem,but can connect with the router

i have a similar problem. My Nexus S connects to my router only within a few hours after a router reset. Then it stucks at "obtaining ip" and never connected before I do another router reset.
My home wifi is WPA2 type, and for WEP type wifi my NS never got connected.

[Q] wifi does not connect automatically

I'm running infused 1.5. Whenever i go to new places that have wifi ( password already been saved), my phone won't connect to it, worse thing, when I scan, it won't see the wifi ssid...it keeps showing the previous ssids that it found earlier. After I turn off wifi and turn it back on, then it acts normal again (connects automatically to that wifi). It acts weird again when I go to another place.

I have the same problem, but I'm stock other than root, so I don't think it's the rom.
I recently added access points to extend the range of the two wifi networks I connect to most often. It almost seemed like it wanted to treat the new access points as new SSID's, which I have always assumed was part of the problem. I just haven't had much time to work on it.
I'm using stock Tom and this has been going on since day one.

Any resolutions here? I just got an infuse 2 days ago and I'm having this problem.
Is this an issue with every infuse or should I exchange it? additionally, if its a problem with all of them, are there any custom roms out there that address this issue?
This is a killer for me, and I'm constantly moving around in an office without consistant wifi so I have to turn wifi off and on like 20 times a day to make sure I just use wifi for data. Very annoying.

Same issue here. Seems to only do this at home with a Netgear N600
You guys need to provide more details. Exact roms and your wireless settings and what security the network is on.

No fixes that I have found so far, unless there are some broadcom DHD commits in pershoot's Galaxy Tab 10.1 kernel I can kang. (The problem seems to have gone away with the latest of is kernels for the 10.1.)
We have the same Broadcom wifi chipset as the Tab 10.1 and many other phones - this is a common issue across all devices with that wifi chipset. Some sort of sleep/power management bug in the kernel driver. Broadcom sucks.
I have this same issue with my Infuse, Infused ROM 1.5.3, kernel 2.6.32.9.
Typically I connect to 2 AP's, one is WPA2 personal, and the other is WPA Enterprise, PEAP, MSCHAPv2
I usually need to turn wifi off and back on in order to connect to my saved profiles.
95% certain rom/kernel doesn't matter - hell, device doesn't even matter. If you've got a Broadcom BCM4330 wifi chipset, it'll happen.
It's the rom! I had the same problem on stock Froyo and now I'm on gtg465x's GB 2.3.3 infused V2.1.0 and this problem went away.
Anyone else confirm improved wifi with this rom? Especially the connecting/disconnecting loop?
Note that my last post on this subject was when Gingerbread had only been out for a few days:
It seems that the issue is fixed in the Rogers Gingerbread kernels. I'm actually surprised, since the Honeycomb kernel for the Tab 10.1 is in theory newer but it has the problem. However, even that kernel stopped having problems after the maintainer made a bunch of power management tweaks.
So basically any Gingerbread kernel should be OK.
That means I will have no hdmi and 15fps video capture though, right?

Wifi is gray after sleep; no internet

I've had this problem before with Honeycomb. When I would wake the tablet up after it had been in standby for a while, the wifi connection would be gray and I would not be able to go on the internet. Simply toggling the WiFi switch off and on would fix the problem, yielding a blue WiFi signal and internet, but this becomes a hassle.
I had at some point flashed Prime! 2.1.0 and found this to be the only ROM that didn't have this WiFi connectivity issue.
Unfortunately, after updating to stock ICS the issue came back (and is also present on the Revolution rom). Prime hasn't updated to ICS at this point so I was wondering if any of you know what is going on and what can be don't about it.
Thanks
hey mate,
I have been experiencing the same problem even before the ICS update.
simply turning off and turning on the screen only gives an indication of how strong / weak the wifi is.
is it indeed a hassle
Thanks wzseow,
Does anybody else experience this?

Can anyone help with my WiFi issue?

I am S-Off, and rooted
I had this problem with the ICS which I flashed after S-Off, so I rooted and flashed eleganza, SAME PROBLEM?!
Here's what happens-
WiFi connects with Router and shows correct strength, connects and downloads or surfs web or whatever then just stops dead! The device obviously thinks its connected to Wifi as it doesnt let the mobile signal kick in. If I disable WiFi it then connects to mobile network. If I reconnect to Wifi it works for a bit then disconnects as before.
This is driving me insane! any suggestions?
Tried changing Router channel and security encryption.
i never had the same problem, but the most common solution when wifi is not working on ICS is that you should do a complete wipe, dalvik and cache and format all partitions except SD-card.
that usualy helps, let me know if it worked for you...
Did a superwipe before I Flashed the custom Rom, which should have done all that I think, cheers for the reply
Do you have installed custom kernel, I seem have bit problem with my signal when using faux123 beta kernel. So my suggestion is try install and using other's kernel like the final version faux123, sebastianFM or stock kernel. If you using cpu control application try not to set the lowest to low.
On the Advanced Wi-Fi try to set "Keep Wi-Fi on during sleep" to Always.
If you have set "wifi.supplicant_scan_interval" on build.prop try to decreased it.
I am using sebastianFM , "Keep Wi-Fi on during sleep"is already set to Always
Now tried new rom and new kernel and have now supercid. Any ideas?
Search for WiFix in this forum, it's an app, it might help ?

I had a similar problem with all the Elegancia versions that I tried (3.4.1 and 3.5.0).
It recognised my neighbours' routers by not mine, I did not have wifi signal at all.
No problem with any other ICS rom such as ARHD, InsertCoin and CoreDroid.
My router is the O2 Wireless Box (which is actually Thomson ST780). If yours is the same there might be compatibility issues between Elegancia and this specific router.
I had a similar problem with ARHD few months ago... Did a superwipe, flashed the same rom again, flashed radio other than was used in a rom and didn't do any backup restore... I think some wifi application messed with crucial wifi settings but I flashed other radio because I wanted to find solution faster... So don't know exactly what helped..
I've always had this issue with ARHD since ICS leaked. I could always get connected to other WiFi connections, but not my own at home which uses WPA2. The phone does actually show full WiFi signal and thinks it's connected, but can't really get out to the internet.
I could get it to work by either a) flashing another ROM that worked for me like InsertCoin then flashing ARHD directly over it without a wipe, or b) just wiping and going with InsertCoin from the beginning haha.
I used mostly IC anyway during Gingerbread times, so it wasn't a big deal for me to stick with IC for ICS. But I still wonder what causes this issue. I read in the ARHD thread that there are WiFi-related files that can be replaced to make things work, but I figured that would eventually get annoying for me since I flash often.
I found the same problem with two different Android phones after rooting.
Connects, works for a short while then no traffic gets through. Disconnect, then reconnect usually works for a few seconds more?
My solution was to reconfigure the router...it had maximum speed settings that allows 75, 150, 300. When I set it down to 75 it started working reliably.
Same as above...I was using WPA2 and it only affected my home router.
Not sure if same issue, but worth a try!

[Q] CM11 WiFi problem

Hi,
I'm on 11-20140804-SNAPSHOT-M9-ville, official (HBoot 2.15), Radio 1.35a.32.45.27
I have a strange problem with my WiFi. I can't really tell what details are important, so I'm gonna give you guys the full story.
After rebooting, everything works fine and the phone instantly connects to my WPA2 PSK secured WiFi at home. When I'm at university during the day, I'm connected to another WPA2 WiFi (maybe some of you have heard about "eduroam", TTLS/PAP authentification), which also works fine. However, when I get home in the evening, my phone won't connect to my personal WiFi at home any more. I see the SSID, but when I try to connect, it says "Connecting..." for a milisecond, then just jumps back to showing me it's a WPA2 secured WiFi without having done anything. I get no error message or anything, it just doesn't connect and doesn't even seem to really try to connect.
When I reboot the phone it instantly works again without a problem.
Any ideas? Are there error logs for failed WiFi connection attempts anywhere for further analysing the problem? Any hint is appreciated!

Hi,
I had exactly the same problems with m8. I have a Virgin Superhub 2 at home which broadcasts on 2.4 and 5 Ghz. After disabling one of these frequencies, the behaviour briefly changed. Then went back to not working. With eduroam all worked nicely.
I read somewhere that I should activate the "Scan always available" setting. Sadly, I didn't get a chance to try that because I was so fed up with
- the significantly lower sound on CM (is that something you experience with radio 1.35a?)
- mobile signal drops
that I wen back to Maximus 10 where I have no problems at all.
I had radio 1.15 and 2.15 HBOOT when I had those problems. Now I'm on also 1.35 with Maximus 10 and problem free but would like to return to CM if the low sound problem and the WiFi problem could be sorted out.
Here's an interesting little detail I noticed: When I stand right next to my router (full WiFi signal strength) and click on my WiFi and choose connect, the signal strength drops down to one bar immediately. Also, the eduroam network changes from "not in range" to "disabled".
Playing around with the WiFi options didn't help.
edit:
What exactly do you mean by lower sound? That the phone's maximum sound volume is lower than normal? That's something I experienced on my old htc desire, but not with my htc one s. Also mobile signal seems to be stable, no signal drops. The only thing I found curious is that with activated mobile internet, it often changes between 3G, H and H+, but judging from google search results that seems to be normal or not connected to the custom rom.
went through the CM bugtracker, apparently it's a known issue without a solution
https://jira.cyanogenmod.org/browse/CYAN-3923 if you want to know more
One last question, maybe someone here can answer it: As far as I understand the issue, it's a problem with an old WiFi driver and the corresponding kernel modules.
Wouldn't this issue then be present in all ROMs which don't use the stock kernel? Or did I misunderstand something?

Same problem here with Miuri. Tries to connect and then gives up.
The problem has been resolved by the CM11 devs. I'm running nightly 20140819 and it's working fine now for me. :good:
