I have used this fix successfully on several different ICS (Ice Cream Sandwich 4.0.X) and JB (Jelly Bean 4.X.X) tablets to fix intermittent WiFi problems. It is simple and worth a try if you are having difficulties:
Unfortunately you'll need access to the root directory either via ADB or by rooting the device.
There is a file, wpa_suplicant.conf, that contains the WiFi connection instructions for networks that you have previously connected to. Deleting this file and letting the Operating System rebuild fixes a variety of intermittent WiFi issues (not hardware issues like poor signal.)
Locate the wpa_suplicant.conf file in data/misc/wifi using ES File Explorer or some other method of your choice
Turn off WiFi (Settings - WiFi)
Rename the file wpa_suplicant.conf.bak or just delete it
Restart the tablet
Turn WiFi back on
Restart the tablet again
Jelly Bean 4.1.1 Dropping, Difficulty Connecting
I am going to add to my own post. I found something that fixed the Jelly Bean dropped WiFi issue - the WiFi Connector Library
The JB WiFi problem:
WiFi works fine if you connect to a secured network (WPA, WPA2.) But if you are connecting to an unsecured WiFi network, one with no password protection, it is difficult to connect and once connected the WiFi drops frequently (30 seconds to 1 minute for my N90II RK3066.)
This is again an easy solution to try. It worked for me:
Download and install the free app WiFi Analyzer
After the connection has dropped or while still in the difficult to connect phase, launch WiFi Analyzer
Use WiFi Analyzer to connect
Go to the AP List View (middle button at bottom)
Click on the network you want to connect to
It will ask to download WiFi Connector Library
Select "Yes Please"
Play Store will launch
Install the library
You should be A-OK once the library is installed
It runs as a background service. I can only guess why this works, but after three days of messing with this issue, I think I'll just smile and go on to something else.

I have recently returned to my apartment with my brand new archos 70. I use WPA2-PSK encryption for my wifi network. at first everything was golden, I could browse the web and whatnot just fine. as of a few days ago, wifi has not been working correctly. my device connects to the network (pulls an ip address from the router) but when I try to browse web pages or open web based apps they hang up and act as if I have no connection. it works fine on other networks (to limit the problem to my network) I have tried doing a factory reset of the device, tried power cycling my router and modem with no luck. I have also changed encryption types to no avail. i have the latest firmware for the gen 8 series. also from time to time during this session of events, sometimes it will connect to the router, then disconnect and reconnect. I have no clue whats going on because I havent changed any router settings since I got back. the only other devices on my wifi network are two laptops. any help would be appreciated.
you mean you restored to the factory settings ran through the start up all over again and it still won't connect to your router? have you tried any other types of connections or routers?
I had this problem just the other night was this close to reformatting the whole thing. but I solve the problem by turning the device off, then holding the reset button while it rebooted to turn it off again, an reinitializing the drivers.
how do you reinitialize the drivers? I did a factory wipe. and it connects, it shows as having network connectivity (even my router lists it as a dhcp client and currently making use of the access point) but no internet functions work. ive connected to other networks fine.
This happened to me when I first got my A70. What I had to do to fix it (after getting incredibly pissed, reformatting twice, and almost returning the thing) was to set it up to use a static IP address on my home wifi network. Don't know if it'll solve your problem, but it works beautifully for me and I'm able to enjoy the device now.
Just remember to uncheck "use static IP address" when you get on other wifi networks.
well, I set up static addressing, gave it a private ip, set up the gateway and dns, and it still wont connect to anything.
If set as wireless N, set as N+G or G only, latest firmware may have trouble connecting to wireless N networks.
na, I dont have it set to n, I have it set to auto which I believe puts it to g with my archos. thing is, it used to work. now it suddenly has problems.
Im beginning to wonder if the archos tablets are just picky about wireless routers. I wouldnt think so...
Upgrade the firmware
Archos published a firmware upgrade to solve this problem (December 2010). The related bug in the release notes is...
Wi-Fi: fix Wi-Fi stuck after a while when using WPA2/AES encryption mode
The new firmware download link is in the Archos website.
you can download the firmware to your computer, copy it to the root directory of the tablet using the USB cable, and run the upgrade process in the tablet.
... or you can use another WiFi network (without WPA2/AES) and download the update in the same tablet
Note: I cannot send the links, however you can use the information to search the links in the internet.
I usually have wifi and data permanently enabled, with my apps using my home wifi to connect to the internet most of the time. I've found that a number of apps (e.g. Android Market) don't always manage to obtain an internet connection, despite a number of retries, but if I close them and open Opera Mini it establishes a connection immediately and thereafter the other apps can also access the net again.
I've frequently needed to use Opera Mini in this way to "kick start" the internet for other apps which are unable to connect by themselves.
Has anyone else had this issue?
Never had this issue, are you trying to connect after waking the phone up? Check to see if wifi sleep is turned onto never, if that fails try another kernel as newer ones have fixed previous wifi issues.

Yes it's after waking the phone that I get this issue. I have wifi sleep set to "never". I'm running stock kernel XWKI4 (updated via Kies), unlocked.
Does this sound like a "known" problem?
Hey everyone
Just picked up this phone shipped from overseas. I have installed CWM and rooted the device. I have turned the phone on with a SDcard (but no SIM card). I have connected to my LAN at home to try and browse the internet - i get the basic andriod error message - no webpage will load. Sometimes the error message doesn't come up instantly, it takes about 15-20 secs to error out.
I originally backed up stock ROM, then used Darkside Superwipe to then install Andriod Revolution HD latest version from these forums - still had the same dramas. Restored original image and it mdoesn't seem to have changed anything. Willing to try whatever I can to fix the issue, or I will return the phone as faulty.
* Correctly connected via WEP, full strength signal
* Mobile data turned on
* Up/Down arrows for Wifi seem to light up, but nothing happening
Any ideas or suggestions as to what i can try? Baseband vers XXLG8

hmmmm did you check your router and verify if the connection was stablished correctly? I mean no MAC filtering or anything.
try to recover the phone using kies if that doesn't work then it's a faulty phone
When you are connected to your LAN, does the phone shows what IP it has? Furthermore, go into the dailer and enter *#0011# then hit menu > wifi and do a ping test. If it passes, then there could be some issue with the browser (very unlikely). If it fails, then there might be some connection problem from the router end like alankstiyo mentioned (mac filtering, dhcp off, etc).
So I rooted and loaded the custom ROM on my Xperia X10 exactly following the instructions on the video found here : http://forum.xda-developers.com/showthread.php?t=1305945 (Installed the ROM specified in the OP of that thread)
It works well, except for one issue. The wifi doesn't connect automatically to my home network even when within range; one second it is connected and the next it disconnects and doesn't re-connect. I then have to go to Wireless settings and wait for it to connect, which might happen immediately or after I select Connect. Sometimes, it just goes through a Connecting-Disconnected loop. Any ideas?
I've already set the sleep policy to Never and forgotten the network and added it again.
Apologies if this was answered before; if it was, I'd really appreciate someone pointing out the solution to me.
Open build.prop in root/system, mount as r/w
Search for this line and change scan interval to 30 second (or fewer) :
Code:
wifi.supplicant_scan_interval=30
You're done :beer::thumbup:

From first impressions, that *looks* to have sorted the problem out. Much thanks :good:
Unfortunately, that hasn't solved the problem, even after setting the interval to 10.
The problem goes like this:
I'm within WIFI coverage area of my home wifi, and the first time I switch wifi on, it connects automatically. After sometime, it just disconnects without reason as I'm using my mobile without moving out of coverage area. Now the most irritating part is that it doesn't connect automatically again. I'll then have to go to my wifi settings, select my wifi network (which proves that it's still in range) and select connect again. This again doesn't work all the time, and sometimes it just goes through the scanning->connecting->disconnected cycle. wifi sleep policy is set to Never fwiw.
I want to know how to stop it from disconnecting randomly even when within range, and connect automatically when in range, as this is extremely infuriating to use now
Is this a known issue with the mod that I'm using? If so, is there any other mod that I can use?
PS - The wifi was alright in the original SE device before rooting.
I have had this happen too.
I'm using DoomKernel V6 [root] on GB 2.3
Wi-Fi is active in a Wi-Fi coverage area with a stable connection and good signal.
Screen times out and after some time the phone is used again and screen unlocked.
Wi-Fi does not attempt reconnect to Access Point.
Status shows Wi-Fi in a state of scanning.
Preferred SSID is shown as available with good signal., but not connected/connecting
Disable Wi-Fi and re-enable Wi-Fi
Connection is re-established.
I have an XPERIA S v4.0.4 in the same Wi-Fi coverage zone using the same SSID and it connects every time. Just unlock the screen and a couple of seconds the preferred SSID is connected/re-connected. Every time.
XPERIA X10i
I did at one stage have a timed Airplane mode app that would disable Telephony and 6 hours later re-enable Telephony.
I was on a GB v2.3 build with DoomKernel V6 and XS system apps and after Telephony had been disabled is was _not_ possible to establish a Wi-Fi connection without restarting the phone. Although some times you could 'jag' it and make a re-connection, but mostly, it would only say disconnected and no options would re-establish a Wi-Fi connection to the preferred AP even when it was seen as an available AP and good signal. Disable and enable Wi-Fi did nothing.
After numerous other ROM/Kernel installs over time, I'm now back on GB v2.3 and DoomKernel V6 [root] with XS system apps.
This time round I only have to disconnect/re-connect to establish a Wi-Fi connection. No more phone reboots required, even in airplane mode.
Many times the Wi-Fi connection does re-establish itself, it's just a nuisance when it doesn't do it every time and you have to disable/enable Wi-Fi to establish a connection.
What I've tried without success.
[X] Added a static ARP on the router
[X] I changed wifi.supplicant_scan_interval down to 50 from 120 no change after a couple of days.
[X] Changed advanced Wi-Fi timeout from AC power and screen-off
I'll check logcat next time and see if that gives any clues.
Thanks for the input
Now, can someone swoop in and tell the solution?
Anyone?
If no one has any idea, are there steps on how to install a new custom ROM instead of the existing one?

seems that your bootloader is locked because i saw on that thread that you talking about that you are on Zdzihu cm7 rom with his kernel for locked bootloaders ... so i recommend this one to you :
http://www.mediafire.com/download.php?zhdzap0cek4pkvh
by ThJap its totally fast and stable with no issues
http://forum.xda-developers.com/showthread.php?t=1193001
just download the zip file and put it on sd card then go to xrecovery :
1. Full wipe, Wipe dalvik cache, and wipe battery stats.
2. Flash the ThGo_v.XXX.zip package via xRecovery
then its done.

Hello, for quite some time I have problem with connecting WiFi to my Android TV. I tried everything, from Android reset, router reset, changing password, WiFi name, changing from DHCP to static IP, installing WiFi apps like Avast WiFi manager and nothing helped. The exact problem is that WiFi is disconnecting only when I open any app. For example, I connect WiFi normally and I check connection on router and router see that Android is connected so everything should be ok. But when I open YouTube, main page is just loading and at one point it says there is no connection, after leaving app WiFi icon that is showing signal strenght shows very low signal, only one dot. After turning WiFi off and on everything is normal again until I open an app. About notifications I am receiving them so that means that TV is successfully connected to internet until I open an app. This is weirdest problem I ever had since I am using Android devices and Internet. My TV have MBX S812 with B.S805 chipset. It have 1GB RAM/8GB ROM with Mali 450 card. Android version is 4.4.2 with kernel version 3.10.33. About recovery mode this Android box don't have it at all. There is reset button but it's not opening recovery mode it just resets Android. Android is not rooted. After reseting Android I can't even sign in to Google Account because when he tries to use WiFi to sign in it say there is no connection. I really don't know what else I can do now. I hope I provided enough info. Sorry for long text and thanks in advance!
