Strange network-slowdowns

[-bm-]

Hi there!

I have a strange problem with my Gentoo-laptop. I have got a small DSL-router at home. I connet my laptop with that either by WLAN or normal LAN.
But the connection is horrible slow, there is no difference between LAN and WLAN. It looks like if when I surf a website, every single request (for a several picture for example) takes sometimes seconds until he starts to transfer data. If the transfer had started ones, he reaches maximum 90kb/sec. When downloading bigger files via ftp, he sometimes slows down or stopps within. This is no DSL-Problem, other computers in the network have no problems at the same time.
If I boot Windows on that Laptop, network is fast again. But IP/gateway/Nameserversettings under windows and linux are equivalent. Under Linux even connections in the local notwork are slow.
My Laptop is an IBM Thinkpad R40 with Intel Centrino WLAN and Intel Pro 100 LAN. I tried several 2.6.x-kernels. Actually it is gentoo-dev-2.6.5. I also tried several drivers, both for the Pro100 in the kernel an for WLAN I worked with ipw2100 and the linuxant driverloader. It all makes no differences.

Any ideas where to start?

Thanks and I'm sorry for my attempt to write in English...

Have you looked at the DNS servers your gentoo machine is using (/etc/resolv.conf). DNS requests were timing out from my gentoo box the other day - then i realised that it wasn't using my ISP's nameservers (I should have looked up the addresses to see exactly who's nameservers I was using - defaults supplied by gentoo during install?)

Hi,

the DNS-Setting can't be the Problem. I've entered the NameserverIPs in my /etc/resolv on my Gentoo-Laptop an on my Gentoo-Desktop. They both connect to the not over the same Router and only my laptop is slow. If i boot Windows on this Laptop with the same Nameserversettings then under gentoo it works perfekt without slowdowns.

Any ideas?

Hi,

Have you got your problem solved?
I just got the almost exactly problem as yours:
while I have a T41p with the Intel PRO/Wireless 2100 mini PCI adapter and with ipw2100 driver at my home, the wireless connection is quite slow in gentoo, while very fast in windows...
But my neighbor's laptop connects well in linux within the same wlan...
But the speed is normal fast when I plug into the wired lan in my office.
As well DNS server is correct.

Anybody has ideas?

I have the same problem on my T40p, but with only one connection.

The wireless connection at my work is fine, but at home it's unbelievably slow. Slower than a bad dial-up connection. But it works well with windows.

Both work with dhcp.

I have found the problem in my case: mozilla takes long time to resolve a name.
By google, I disabled IPv6 in kernel, now things go to normal...
