I've got a problem with Android phones connecting to a wireless network. The network is secured by a WPA key and once you connect you are redirected to a login portal where you enter your AD credentials to authenticate. There is no internet access before you have authenticated at the portal.

This works absolutely fine with Windows machines, OS X, iOS, Linux but android devices (I've tried a SGSII running 4.something, a kindle fire HD, an older SE device) are not having it.

DHCP is dished out at as soon you first join but android devices don't seem to obtain an IP. I have another SSID on the same hardware that's configured in the same way but without the WPA key and android devices will happily join and be redirected to the portal no issue.

Does anyone have any idea what android is trying to do after the intitial WPA authentication that means it's not happy to get an IP? Does it instantly need to get out to the web or need specific DNS or something?

Any thoughts appreciated.
 
I've made progress by changing the encryptions from WPA2 to WPA which android will now connect to and obtain an IP address but it refuses to open the login portal. So infuriating.
 
All i can tell you is that Androids do an instant lookup to google on Wifi-connect and can then generate a system message if you like, to inform the user (but not all phones will).

I have the same setup at Work (it's actually using the cisco WLAN visitor system rather than AD but i still get the login page) and it works across all my handsets. I even have it working with personal certs so I'm not really sure why you're having so much trouble.
 
Thanks for that.

I've had it working on a handset running 2.3.4 now so it's at least part working. Need to test out some more versions of android. Isn't Android super!
 
Well, it's different :) If you're doing AD login do you allow MSCHAP / PEAP-GTC? This obviously isn't a perfect solution but it might avoid your webpage.
 
Seems to be working across all devices now which is good news. Thanks for the help.
