IOS 5 wifi wpa2 enterprise problem (bug?)

Hello,

I just upgraded some of our devices to IOS 5 and wifi stopped working. We are using WPA2 Enterprise with EAP-TLS and all the devices with IOS 4 still work fine.

Is anyone experiencing this kind of problem?

Thanks

Andrea

Ok, I think I've found the problem: IOS5 dropped support for md5 signed certificates. Finding this information was very difficut, I hope this post to be useful.

Thanks

I'm probably having the same problem.

Had a working wi-fi on my ipad 2, the internet was working good.

Then i updated to IOS5 and it says that I cant coonnect to the wifi. But the wifi-icon i n the top left tells me iäm connected, and i can find the network in general-settings-network-menu and tap in the password without any problem.

My other diecves i s working ok on the same wifi, and i have restoresd the ipad to factory defualts, and it doesnt make any difference. 😟

Same Here. We need a fix for this ASAP. Specially since like we work at a doctors office and no wifi is very very inconvenient!

The problem I was speaking about happens only if your wifi network is using WPA2 Enterprise with EAP-TLS; in that case ask you network administrator to check that the certificates of the radius server are SH1 signed and not MD5 signed, since the latter signature method has been deprecated in IOS 5.

If you are not using WPA2 Enterprise and can't connect to the wifi network you have a different problem and I don't know how to help you.

Regards,

Andrea

I am using TeliaSonera Homerun at work and in town. TeliaSonera is the major Incumbent telecom and internet operator in the Nordics, especially in Sweden and Finland. I expect the WiFi to work with their service regardless of how the certificates are signed. At home the wifi device (an ADSL access device from TeliaSonera) uses WPA2 and I'm not interested in how it's signed. I bought the IPAD just a couple of weeks ago and upgraded yesterday. I expect it to work also after I upgraded. I saw no warning that I shouldn't upgrade if I use WPA2.

So fix it Apple! Now!

Andrea,

I seem to be having the problem as well. My Certificate has SHA-1 with RSA Encryption as the signature algorithm. Is that the same as the SH1 you reference? If so, I'm still having the problem for a different reason.

Yes, when I changed the radius server certificate from MD5 signed to SHA-1 signed the network started to work. Perhaps you have a different problem ...

Using a WPA2 Enterprise network with PEAP (MSCHAPv2), same problem, does not work anymore (whereas iOS 4 did it fine). Looks like Apple needs to fix this urgently, how can we transfer this information to Apple Development?

I am having the same issue. For me I have to reconfigure wpa enterprise on my school's peap mschap-v2 every time I want to use it. This is extremely frustrating since it used to reconnect just fine on iOS 4.

I think i kinda fixed it, what i did was i put my phone back in to restore mode manually (I do not know if that helped) then i reconnected to itunes and it booted up with the internet after a couple of hours of installing and updating.
