Hi, I've got a network problem since I tried to install different distros of linux on my old laptop.

The installation and all that seem fine to me. No hardware problems and the system can connect via DHCP. I can ping and host different internal/external ips/sites but I cannot access the internet except for the firefox startup page(it loads pretty fast) and sometimes, google. Traceroute returns no result either.

This problem is very annoying, I wonder what has gone wrong?

I've already googled and tried to solve this myself, the best I could come up with is something with window scaling, I tried setting that to 0 but it didn't help.

thx

you might want to try changing your DNS servers to opendns. read this http://prash-babu.blogspot.com/2008/04/how-to-configure-dns-servers-in-linux.html

Thank you for your reply.

I've done setting up a static ip and changing my dns to opendns and I still have this problem.

I use an adsl modem and a router, should I try connecting directly to the adsl? but my other PCs (one xp one vista) are doing fine.

so I tried to directly connect via adsl too. and it didn't work. ugh

route -n says


218.20.52.1 0.0.0.0 255.255.255.255 UH 000 dsl0
169.254.0.0 0.0.0.0 255.255.0.0 U 000 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 000 lo


but then I already got everything I need on this old laptop from the DVD now. So maybe I can just leave it at that.
