My laptop's wireless randomly stopped working.
I'm in a hostel in Sydney, everyone in the house is connecting just fine, however my laptop is connecting to the wireless network but getting an "Invalid IP" and the icon has that yellow exclamation mark.
I went to a McDonalds this morning to try the wifi there and it connected just fine.
I also tried restarting the router, same thing.
Any ideas on what might be wrong?
Thanks in advance!
