Currently Being ModeratedNov 23, 2010 3:08 AM (in response to wifi crash)I'm having the same problem. If I go to settings, it finds the network, and looks like it's connected but the WiFi icon doesn't appear on the phone's title bar. It just says "3G"iPhone 4 16GB, iOS 4
Currently Being ModeratedNov 23, 2010 3:32 AM (in response to pupps)Same problem here as well!
I finally upgraded from 3.1.3 since reports showed that the user interface speed had increased, only to find this bug. The reason why I upgraded was to make use of an app on free hotel wifi when I go overseas - this just ruined that.iPhone 3G, iOS 4
Currently Being ModeratedNov 23, 2010 4:25 AM (in response to wifi crash)I had the same problem after upgrading to iOs 4.2.1 on my iPhone 3GS, i could connect to my Wi-Fi, but no internet access... But i tried this and it worked:
If you've verified that your settings are correct and the issue persists, try the following:
- Tap Renew Lease to acquire a new IP address, DNS, and search-domain information from the Wi-Fi network.
(Settings-Wi-Fi- tap the ">" next to your network name and then tap "Renew Lease" )
Hope it works for you as well!iPhone 3GS, iOS 4
Currently Being ModeratedNov 23, 2010 6:59 AM (in response to pupps)this happened to me on my Ipad and Iphone, try 'resetting' the network setting then do a reboot of the device... Worked for me.

Currently Being ModeratedNov 23, 2010 7:02 AM (in response to wifi crash)Something must have been in this update for wifi, but I couldn't find any info on it. I have an iPhone 4 and it actually FIXED my wifi connectivity issues. And so it goes, I guess.PC, Windows Vista
Currently Being ModeratedNov 23, 2010 1:34 PM (in response to Mr_K)Glad to hear about the successful reinstatement of your Wi-Fi connection. Next time you have an issue you might like to consider the following procedure.
Its always a good idea with any upgrade that you forget the network on the iPhone switch off Wi-Fi then power off the iPhone 'menu and power button held on together until the Apple logo disappears and the phone is switched off.
Then power off the Router+Modem or Router and Modem. If you have a dynamic IP address on the Internet connection you may have to leave the router off for about 5 minutes so that the IP Lease is released/revoked.
Sometimes it might be necessary to also forget the iPhone with in the Routers settings in other words release the IP lease issued to the iPhone. You can of course make the IP address of the iPhone permanent should you so choose.
Another issue that needs to be check is which channel you have selected the default is usually '6' which you may be sharing with other users. You may be able to improve your Wi-Fi performance by choosing another channel.
There is a piece of software 'Free or for a Donation' that will allow you to detect Wi-Fi services in close proximity and what channels they are using. I have no association with this publisher so posting their address in this forum is not an endorsement http://www.vistumbler.net/
Then you power up the Router/Modem check that you have Internet connectivity from a Desktop and then power up the iPhone switch on Wi-Fi and reconnect to the network. Don't forget that you will need to have a record of the encryption password used by the router usually WPA.

Currently Being ModeratedNov 23, 2010 5:08 PM (in response to wifi crash)I definitely need some help on this one.
My son's iPhone can see wifi networks but will not log on.
Even though the password is right the iPhone says it is not.
Have reset the network settings, restored the phone, reset the router, turn the wifi off and on but it just will not log on.
He never had a problem till upgrading the iOS.
If he can't text soon I fear he might need to seek professional help or even therapy.
His fingers twitch and he mumbles incoherently, please help......MacBook Pro, Mac OS X (10.4), iMac, PowerBook G4, iPod Classic, iPhone, iPad
Currently Being ModeratedNov 23, 2010 6:04 PM (in response to markj55)Network passwords are usually case sensitive so you have to make sure that you user upper and lower case as required. If you make a mistake entering the password then if you just delete the incorrect character input then the logon may fail even though you believe that you have input the password correctly. Try inputting the password absolutely error character free and see how you go.. Ant..2 x IBM Core2 Duo 3Ghz Vista + 2 x XP 2 x iPhone 3G OS 3.0 1 x AE 1 x MacMini
