I am using Mac OS X.
I am at a hotel where a website login prompt pops up when you connect to their open wifi. I typed the password wrong, and saved the password on accident. As a result, it no longer makes the prompt, it just times out trying to connect anywhere else.
Things I've tried so far,
Completely clearing my cache, passwords, cookies, everything. Check my keychain access, no keys stored there. Deleted the hotel from my network preferences Rebooted my computer. Checked my saved passwords in FF, it wasn't there. Booted into windows with parallels, same problem. All other browsers same problem.
