I'm on Ubuntu 12.10 (using xubuntu) and I'm trying to surf the web using my mobile phone (plugged to my laptop using a USB cable). For some reason I can only connect to google.com and other google sites (gmail, youtube, etc.), but I get a timeout when I try to connect to any other site.

I can ping any website just fine, I get the IP address and no package loss, etc. Just in case, I changed the DNS to Google's DNS, but that didn't change anything.

I'm going online with an old HTC Diamond (Windows Mobile 6.3) and a prepaid plan (Simyo), if that's relevant. The connection works on Windows XP just fine.

I found this thread, which led me to this thread with a very similar problem, but the solution did nothing for me. Changed the MTU both on the phone and on the laptop to 1492, nothing.

I also made sure that there's no IPv6 problem. "dig AAAA heise.de" gives me back an IPv6 address just fine.

Probably of interest is that using traceroute both on sites that do work (google.com) and do not work (most anything else) gives the same result.

I have no idea what could be the issue here, and what else I could do, so here I am. Help!

Could you start wireshark and record the packages? Try Google and Heise. Maybe we see a difference here. –  qbi Jan 27 '13 at 8:45
    
The problem has been solved in the meantime. I had to set the MTU to a different value (1348) to fix it. The cause is still unknown, though. –  Conti May 7 '13 at 19:11
