AMD Athlon XP
DWL-G510
OS - SUSE10 X64 / Ubuntu 5.xx
I have a strange problem with my wireless connection. Both Ubuntu(X86)
and SUSE(X64) connections pauses a few seconds in when I download or
browse websites. I am not sure what is causing this. There is nothing
seems to be worng. This happens for internet, ssh connections from
other computers, or even pinging the router(192.168.0.1). The SSH
connections(putty) gets disconnected sometimes. SUSE madwifi is the
latest source from svn which I compiled and installed. I have a
windows XP installation on the same machine which works fine. Windows
shows signal quality 85% and KInternet shows 35-37%. Not sure this
means anything.
I don;t think this is a DSN issue, even downloads pauses in between
and continuous. Also if I browse IP Address the same delay occurs
Pinging various sites shows 35- 55 % packet loss.
Here are the things I tried. (SUSE 10)
Disabled firewall.
Disabled ipv6.
Downloaded and installed Madwifi drivers from svn
Disabled eth0 and eth1 (two wired networks, but not connected).
Nothing helped med so far.
My Settings.
