Ever since upgrading to AT&T 2.2, I have a had an issue that on every other reboot, the phone radio does not turn on. I am not getting a SIM error, or any other error indication, nor does the phone go to airplane mode (bluetooth and wifi work). If I check phone settings, I get phone # unknown and no phone signal. Once I shut the phone down and turn it back on again, phone service is back.
I'd suspect a SIM issue, but this did not happen on 2.1. Could this be a bad flash (I could not get Kies Mini to push the firmware, I had to install via Odin)? Has anyone else seen this kind of flakiness?
Bump
Is anyone else seeing intermittent issues of the phone thinking it doesn't have a SIM installed? The good news is that I have not had two reboots in a row with this problem, the bad news is that I do see this on nearly 50% of boots.
I dont have the problem, if it does happens it only happens like once a week for me, it usually fixes it by going into airplane and back to regular

I tried that. On my phone, that does not remedy the situation. The SIM itself has not moved since the update (I can't remember if I pulled it when I ran the upgrade), so I don't think it's a loose contact.
att can fix
Bring the SIM and phone into ATT, they will fix it for you there, hopefully for free, that could work, just unroot before and unflash if you did, then say you have SIM problems and then tell them that you had it in during the update, sometimes that causes problems
I have this same issue. Yesterday after about 5 reboots the phone would not pick up any signal... at times and after several minutes, some signal would show up and then disappear again... After about the fifth time, I turned off WiFi, because it had been on the whole time and that fixed the problem. Signal came back after a while and was stable. Turning WiFi back on did not bring back the problem. I guess Froyo just does not like the WiFi being on when booting the phone. Hopefully this can help others fix this same issue when encountered.

my transformer is acting strange. not sure if it's by design or a glitch.. but i hate it, almost to a point i want to return it and get an Acer..
If i dont use the trans for a while, the wifi diconnects itself, which is what i want. But when i wake the screen, it stays disconnected and will not auto connect. so i try to connect manually, it will not connect at all. keeps saying out of range when i know for sure it's in range. so i have to shut it down and turn it back on everytime to connect. F-ing annoying!!
and if i dont use it overnight or something, the next morning it's turned off, and i can't turn it back on the normal way. i have to hold down the volume down button and power button at the same time to power it on.
anyone experiencing similar problems??!!
WTF!!!
I think you have a faulty unit as I am not having any of the problems you mention, WiFi is rock solid, have been able to connect from standby immediately after pressing power button even after prolonged periods of time on standby.
The only time I had to reset it was once when i installed a battery widget that was not showing after installation, tried a reset which solved the problem.
I have not had this problem once since i received the unit on Thursday. I have even connected it up to 4 different wifi networks and have not had a problem reconnecting to my home when i return.
It could be your access point causing the issue. When i first got my Epic 4g, it could not keep a connection to my 6 year old linksys router. I then purchased a buffalo tech N router and have not had any problems since. The Epic and Transformer now behave as they should.
Try updating the firmware on your wifi unit or purchase a new one.

I'll see if my firmware is up to date on my router. hopefully that's the problem... but that doesn't explain the other problem, It shuts off by itself.
Do any of yours shut themselves off after say a night of no use?
The only time I noticed mine shutting off was when I carried it in a bag but I think this was caused by pressure on the power button whilst in transit, never noticed it any other time.
My wife's android phone had a similar issue with wifi. It wouldn't reconnect after going into standby, and I would have to reboot the phone. I just set the wifi sleep policy to never, which is the same preference I have on my phone. Honestly there is very little effect to battery life on an android phone. However, if wifi shuts off on a phone it would just use 3g instead also using battery. I assume if the wifi goes asleep on the tablet, you lose any push notifications. I plan on leaving mine on for notifications. (Getting delivered today)
Definitely a faulty unit, mine is always connected to WiFi when I wake it. Never had it turn off on its own either.
Make sure wifi sleep policy is set to never, and if you're still having issues, I'd do a wipe of the device could just be some corrupted app or file.
Doesn't sound normal at all. Tough decision as you can't just return it and get another because of the short supply. So far my transformer is exceeding my expectations. This is one hell of a deal at $399, and really makes you wonder what other manufacturers are thinking charging a tablet more than $400.

I don't know about your wifi issue but the sleep problem is a known issue that many others have had problems with. Hopefully it will be fixed soon.
There have been updates to the Wifi driver in the last two FOTAs, maybe when ASUS re-releases those updates it might help.

I did do a master reset and the problem did not go away. and my trans in on never disconnect wifi mode. i'll try another reset tonight see if that helps. maybe i still have some battery saver app that's screwing everything up. this sucks! if i can't get this fixed, i'll return it and get one later when the stock is replinished. The initial honeymoon period is about worn off anyway, i can wait now...
Have you tried this on a different router? The problem may be with the router instead of your tablet.

Mine did this to me once or twice - but I think it is related to the lock screen issue described elsewhere in the forum. Basically, when I got up in the morning, it appeared to be "off" - but I think it was just an issue powering up the screen. I had to hold the power button for a good 10 seconds (to actually shut it down) and then power it back on.
I disabled the lock screen and haven't had the problem since then. I'd really like to re-enable the lock screen though at some point, so I hope they get the issue resolved.
Definitely seems like a bug - but certainly not something that has cropped up for me since disabling the lock screen.
My wifi only xoom is getting random wifi "turning off" during the day which makes me have to reboot the whole device and some times it happens more then 2 times a day. I was just wondering if there was a way to fix this say without having the factory reset and rebooting all the time. I really don"t want to take it back because I just put a screen protector on it and that was a pain.
I have the same problem but I dont reboot the whole tablet, no, instead I turn airplane mode on then back off wait a few secs and wifi is working again...for the time being.
interesting i'll have to look into that when my xoom does it.
thanks
Try wifi enable in the market it keeps wifi from turning off

So i've been trying to figure out why my wifi won't turn on for the past few days. It started randomly turning itself on and off round a month ago and now just doesn't turn on. When i attempt to turn it on, it gets "stuck". If that wasn't enough, the same thing happened with the bluetooth. Now i can't seem to use either. Could anyone tell me what's going wrong and/or how to fix it?? Thx, Im using a D2203
My LG G Flex2 could not get wifi on. It keeps showing "turning the wifi on......" but never gets connected. The bluetooth was also not allowed for connection. I restarted or powered off then restarted, the same problem there. I was trying to put a little piece of paper/credit card on the wifi chip as some videos showed, but likely not on the right spot because the phone would not be turned on if the little piece was there. Can anyone let me know where the wifi chip locates? any other DIY advice? Thanks a lot!!
