I'm having a weird behavior from Mint here. Many sites weren't working with a wireless connection: I could login to facebook, but it didn't load any link, youtube wouldn't display videos, Dropbox wouldn't display my files, among a few others. At least I could read my email.
When I tried plugging in a cable, everything worked smoothly. Now, I know there's nothing wrong with my Access Point - Windows on this same machine works perfectly with the wireless connection.
What could be wrong?
