iPad2 - WiFi Cannot Automatically Reconnect After Hibernation

Go an issue where I can connect to the company Wi-Fi network using WPA2 Enterprise and initially no problems with the connection.
Then the iPad hibernates after not touching it for a few minutes. When I come to pick it up, turn it on, it cannot automatically connect to the Wi-Fi network again and the only way to reconnect is to forget this network and redefine it every time with SSID, security, username, passwords, manually configuring the proxy server, port number, another username and password; all a bit of a pain in the rear. Otherwise, I get the message "unable to join network".

Looking at the network settings in WPA2 it's using DHCP and the info that seems to be retained after hibenation/power up is: DNS and search domains.
The IP address, subnet mask and router fields do not have any content each time the machine turned back on.

This behavior does not occur on any other WiFi networks I've connected to and will reconnect seamlessly each time the iPad is switched on without having to re-define the connection to the Wi-Fi.

Any suggestions on how to fix?

Thanks,

Ipad2 64GB 3G
OS 4.3.3 (8J2)
WPA2 Enterpirise using DHCP

Do you have "Ask to Join Networks" turned ON? If so then try assigning a fixed IP address and subnet mask, instead of using Automatic assignment of IP address. Try powering down the router for about 8 to 10 min, this will allow the router memory to completely clear and allow a clean boot. Remember computers are magic and WiFi is black magic, there are times when it doesn't seem to follow logic at all.

Although this thread is about six months old it was just bumped, so here is some information for anyone that stumbles across it.

Several things often help improve WiFi connections on the iPad. Simply shutting down apps and restarting the iPad can fix most issues.


Quit Apps: To quit an app double press the Home button and the Multitasking Tray will appear at the bottom of the screen revealing all of the open apps. Tap and hold any app icon until all of the icons start jiggling. A red circle with a "-" (minus sign) will appear in the upper left-hand corner of each icon. Tap the red circle and the app will close.

If that doesn't do it, try restarting the iPad and if that still doesn't do it try resetting it.

Restart the iPad: Press and hold down the Home button on the front of the iPad for few seconds until the red slider appears, slide this across to shut the iPad down. Restart the iPad by pressing the power button on the top until the Apple logo appears.

Reset the iPad: You can do this by pressing the Home button and the Sleep/wake button on the top the iPad's case and holding them down together for at least 10 seconds, until you see the Apple logo. The iPad should then reset itself. The boot up process takes a few minutes and then the iPad should be responsive again. More here:

iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting

Distance from the Wi-Fi router can impact the signal as well as interference from other electronics including microwaves, wireless home phones, cell phones, etc. Walls and floors with metallic studs can have a negative impact on Wi-Fi signals as well. Sometimes moving the Wi-Fi modem/router closer to where you use the iPad most can help.

Another tip is to reboot your network and everything on it including your modem, router, etc. while your iPad is off. Turn your iPad back on and see if the connection has improved.

The iPad works best with the WPA or WPA2 security protocol. Setting the modem/router to WPA or WPA2 will often improve and stabilize Wi-Fi connections.

Lastly you can try deleting the network connection on your iPad and then go back and set it up again. Settings > Wi-Fi > tap on your network > Forget this Network.

Here's some more info if none of that works...
