[lug] Tad OT: Cat 5 cable interference?

[Justin]

Well, I believe the network card might have had something to do with 
this problem also. I replaced the nic in the XP box with a known good 
nic and things seemingly are working good now. The nic I had in 
previously had given me problems in the past but I pulled it out of the 
junk box (you know, the box you put bad stuff in so down the road when 
you go to use it again you hope it works box :) ). I haven't noticed 
any packet loss to my linux server and the internet connection seems to 
be running a lot quicker and more responsive than with the other nic. I 
am going to check if I have the 5e cable and get one if I don't have 
it, just to be safe.
