    Me, too. Every time I wake it up it reconnects to the router except the several times it required a toggle of the wifi switch to make the connection.

    Between this and the Biblically atrocious battery life - I am seeing drain when using of 1% per MINUTE! - I am severely disappointed with ICS.

    Mine was doing the same while at home last week. I did a power on/off cycle on the home wireless router, and all has been OK since.

    DO...A...FACTORY...RESET
    DO...A...FACTORY...RESET

    Is this hard to understand everyone?

    ATTENTION NOOBS: IF YOU UPDATED FROM EL29 GINGERBREAD TO FF18 ICE CREAM SANDWICH DO A FACTORY RESET...I REPEAT...DO A FACTORY RESET

    What will a factory reset fix???
    Horrible Battery Life
    Crappy WiFi Performance
    Random Reboots
    Poor Radio Performance
    App InCompatibilty
    Lagginess
    DID I MENTION POOR BATTERY LIFE?
    DID I MENTION CRAPPY WIFI?

    But wont a factory reset delete all my user data?

    YES YOU WILL LOSE ALL USER DATA. THIS NEEDS TO HAPPEN INORDER FOR THESE RANDOM ISSUES TO BE FIXED. BASICALLY ITS LIKE A BAND AID....JUST PULL IT OFF FAST

    If Im not rooted how can I backup my apps and app data?

    USE AN APP IN GOOGLE PLAY CALLED "MYBACKUP" AND ONLY BACK UP YOUR APPS.

    DO NOT DO NOT DO NOT BACKUP APP DATA. APP DATA FROM EL29 INTERFEARS WITH FF18 STABILITY.

    Why didnt Samsung/Sprint make the update.zip wipe my user data?

    THIS IS BECAUSE USERS DONT LIKE SUPRISES. SAMSUNG KNOWS THIS. DO A MANUAL WIPE.

    What About the eMMC Lockup Bug?

    I HAVE DID 13 FACTORY RESETS ON THE OTA FF18. MY PHONE IS STILL ALIVE. IF THIS DOES HAPPEN THEN YOU WILL GET A WARRANTY REPLACEMENT FROM SAMSUNG.

    +1 for this. I don't see a reason a for a factory reset unless you are having MAJOR issues. That being said, if you do find yourself having MAJOR issues, then by all means, try out that factory reset. Just remember to make that backup first.

    OFFS! I'm running Titanium Backup now and backing up all apps and user data - no, I'm not going to gang restore the old system apps - but does that sweep up all the various download folders, etc. I've got some saved photos I'd hate to lose. I've been saving photos to the external SD card, but want to make sure the ones on the internal SD are also protected.

    You cannot believe anything Sprint says. They will "Yes" you to death just to shut you up.

    I had lags after ICS upgrade. Then I did a factory reset. No more lags but the wifi connectivity was still abnormal. And I noticed that the phone remembered all the previous wifi networks it has connected to. I hit "Forget all network" and rebooted the phone. Now it's wait and see.

    Hello guys, I have the same issue as yours... After the upgrade to ics, wifi keeps disconnecting. I have tried various fixes like reboot router/mobile, system restore in my mobile, but nothing changes... If any of you solve the problem, please post the solution! I am using WPA2 mixed security for my wireless, I tried also without security but still the same problem...

    Here is what worked for me regarding Wi-Fi dropping, scanning and restarting (which really drains the battery fast. Go to Wi-Fi settings, long select your Wi-Fi network. Tick the box advanced. Change the frequency from auto to 2.5 MHz. I know my Wi-Fi network is not 5 MHz so this is fine for me. If yours is 5 MHz then try that. It is having he setting to Auto that really seems to cause the issue. Since I did this Wi-Fi seems to stay on without a hiccup.

    I have been having issues with my WIFI since I upgraded to ICS. I have done two factory resets and although that did fix the battery issue.. I am still losing my WIFI signal. It seems like the moment it goes idle... definitely less than 30 minutes... I lose my WIFI connection. I have WIFI set to stay on ALWAYS during sleep.. but it seems to not do that. I thought it had to do with ICS but the other day I was at a friends for a party and I connected to her wifi. I stayed connected all night long never once did I lose my connection. The only difference between the two houses is our router. Now I am wondering if it is my Linksys router that is the issue. I am using the E4200 Linksys wireless router. Of course I have asked them and they say it is not them.

    Any suggestions?

    i'm having similar issues. my wifi turns itself ON, even after i've turned it off. i think this only happens when i am charging it, which just makes it all the weirder. ugh.

    and it drains the already horrible battery life even more. sheesh. i have never felt more like i was sold a bill of goods, and ending up with a lemon. every update seems to make things worse.. :o/

    This has also happened with me, specifically the issue where my phone says I am connected to wifi but wifi does not work. In order to get wifi working again I have to turn it off then back on. This started to happen after the update to ICS.

    Now thinking this was an ICS bug I completely wiped my phone and reformatted everything including the internal storage. I then proceeded to flash a CM 10.1 mod. The Feb 15th build of this particular one to be exact http://http://forum.xda-developers.com/showpost.php?p=36724636&postcount=2. But doing this did not seem to solve the problem. Although now I could tell when wifi was not going to work as the wifi indicator would be grayed out. What is odd is that the triangles within the wifi indicator would still indicate data being sent and received.

    Next I looked at my router being the potential culprit, a linksys wrt54g v4. So I proceeded to flash Tomato to the router. All seemed fine and dandy for the rest of the evening and even when I woke up in the morning. After I returned home from work all seemed fine for about an hour until the problem showed back up, just to clarify this problem also shows up on the wifi at my work place.

    So as of now I am still dealing with this issue. It is frustrating because every other device that uses wifi in my house does not have this issue. I even own a nexus 7 which has never encountered this problem.
