I have a Samsung Galaxy Player 5. Before, I could use everything (Facebook, etc) normally. I'm not sure if I changed anything, but now the browser (Internet) loads everything fine, but Facebook &co. are unable to make a connection (timing out, as far as I understand it)
I'm not sure what I could of changed. This happens on numerous networks, so it's not a router-side thing.
What should I investigate or check?
