Re: [WIRELESS-LAN] iPad spontaneous reboots?
We had this problem with a few of our WAN sites. We did not figure out the problem as oppose to a temp fix. We found that when the following conditions existed, the iPads would reboot. - iPads had to be on version 4.2 - WiSM code 6.0.188.0 - VPN involved I moved the WAN ap's over to older code (MESH code 4.2.176.51M) and this fixed the problem. We have plenty of iPads that were on the 4.2 iOS and the 6.0 code on campus (no VPN involved) and did not have any problems. I have not been to the WAN sites since the 4.3 iOS came out so I have not been able to check and see if it resolved any problems.

RE: [WIRELESS-LAN] iPad spontaneous reboots?
There are lots of discussions like this online: http://discussions.apple.com/thread.jspa?threadID=2599544 where it happens with enterprise and home networks alike. in our case Apple didn't hesitate to tell us to go to 4.3. I was in the same location witha pre-4.3 iPad for almost 24 hours and couldn't get the condition to repeat on our standards-based WLAN, nor did it happen again to the users that initially complained. It's always fun when toy-quality wireless devices hit the enterprise WLAN (he said rather sarcastically). I do know that I would have a very hard time justifying making network changes to an otherwise stable enterprise WLAN when the only devices to have problems out of thousands of clients are a few iPads and iPhones.

Re: [WIRELESS-LAN] iPad spontaneous reboots?
I haven't heard about about any iPads rebooting due to wireless, but I have two thoughts: 1) Is it rebooting periodically? If so, is it really just disconnecting from the wireless network periodically? (Google wireless disconnects after 30 minutes and you will find quite a few hits). One of my people, Nathan Broome, found that we had a client disconnect parameter set to 30 minutes. This setting was probably just carried forward from a Cisco default setting from many years ago. You can disable the setting in the Cisco Wireless LAN Controller by going to WLANs - WLAN ID - Advanced and unchecking Enable Session Timeout. 2) Set up a non-broadcast SSID on another subnet and have one of the people who have the problem use this SSID. This might help to determine if the problem is with RF interference or some network traffic that is taking out the iPad. If the iPad is rebooting due to traffic then you could set up a continuous packet capture and try to find the packet that is taking out the iPad. I worked with my staff to set up a non-broadcast SSID here and I find it useful now and then.

Have not heard of this happening here.

RE: [WIRELESS-LAN] iPad spontaneous reboots?
One add- these are 3G/Wi-Fi models, actually with both radios on- in the NYC area, if that makes any difference.
