Repeated disconnects on WPA PEAP network
- by exasperated
My school has a WPA PEAP network with GTC inner authentication. I am able to connect to the network, but once I load a website or two, the network become unresponsive (i.e. in Chromium, it gets stuck at "Sending request"), and I'm eventually disconnected. Any help will be greatly appreciated.
Here's some log output. I can provide more if needed:
