The campus network has a roughly 10 times bigger bandwidth than my home network (100 Mbps vs. Now one other strange thing is that if I go to my university's campus and I log on to that network, I don't see the problem anymore (I can access any sites), but my ping times (~400ms) are still a lot higher than other peoples (~5 ms). When I run windows in safe-mode, I don't have the problem, so I assume it's not one of the drivers acting up.It's not the wireless, as I have the same problem if I plug a LAN cable in.It's not my hardware because I'm also running ubuntu without experiencing those problems.It's probably not the router, as I'm the only one in my home network having that problem.
Here's how far I managed to get with my diagnose: I'm having some pretty weird problems with my computer, I have huge ping times (sometimes around 10000 ms) when everyone else on the network only has 25 ms ping and I cannot access some websites (for example ) while others on my network can.
