A strange USB NIC


Hello, I bought a new USB ethernet adapter, but it seems not to work so well with debian. This is pretty much how I connect everything.

Verizon phoneline<--->DSL modem (192.168.1.1)<--->Dlink wireless router (192.168.7.1)------wireless to laptop(xp) 7.100
\
\ethernet cable to debian (192.168.7.101)


Here is the strange stuff. On debian, I can exchange files
with the XP laptop at rate of 700kb/s or so, both upload and
download. I think it is ok since the NIC based on USB1.1.

However, I almost CANNOT access any website! All what I was able to do is just to see the frontpage of google.com or other webpage whose size no bigger than 1k bytes. I could not download
any file from a remote ftp. But I could upload files to the remote public ftp server. Anyone knows how to sovle it? BTW: I checked the USB NIC, it works fine with the windows XP laptop.

I am not convinced this is a problem with your NIC. Can you get it to work by connecting your Debian system directly to the DSL modem? I am not sure whether you would need a crossover cable for that. (I think they are intended to be connected with a standard patch cable.) You would need to change your default route unless it is configured through DHCP.
