You might try what this clever fellow did:

it worked…
but i never had to make any changes to resolv.conf in my previous distros and internet is running slow also this time :frowning:

I have been getting a lot of slowdowns too. I always disable IPV6 in Firefox as well as in YAST / Network Settings. You might also try this window scaling command:

Just an information if anybody else has this problem:

After installing openSuSE 11.0 I noticed that my internet speed is somewhere near 1kB/s, connected to a 2Mbit DSL router. After searching a bit regarding my network card (Realtek RTL-8139), I noticed that I have to set a system control parameter to get full speed back. The setting I had to apply was:

net.ipv4.tcp_window_scaling -> set to 0

After setting this speed was back at 200kB/s

Checking your current setting can be done as root using this command:

cat /proc/sys/net/ipv4/tcp_window_scaling

Setting it temporarily for testing by using this command:

echo “0” >/proc/sys/net/ipv4/tcp_window_scaling

and setting it forever can be done by adding the following line to /etc/sysctl.conf

net.ipv4.tcp_window_scaling = 0

and running “sysctl -p” once.

I hope this helps other having similar problems.

Wow I had the exact same problem last night. There are actually two resolv.conf files. one is etc/ the other in etc/ppp. I made sue DSN resides in both and it worked.
