HELP, Linksys and D-link Wireless WTF
 

Ok so i have a Linksys Wirless-G Broadband Router..
Which works fine and nver a problem.

I go get a D-LINK wirless network card for my PC and install the driver first like the booklet says and then the card, the card picks up the linksys and then the linksys goes down.
YEA
Cannot connect to it via wireless or cable.
So i unplug it and after a while it comes back online.

Then same shit again and will not respond at all.
This week i have had 2 linksys wireless routers fail on me.
Is it the user or is it the shit?
