I wish you had told us this before so you wouldn't purchase a new ethernet adapter, sorry. =)

Let us know if that solves your problem

@WinLinMac01 its chill because now I do have a working ethernet adapter with Leopard just need to get a new router, should I just buy a new linksys router? oh btw that solved the problem with the lag.

so it was the router
but i wouldn't by a linksys thats just me
i would get a different brand
ummm don't get a dlink N router though that was my problem

which one would you suggest?

i know a dlink G G+ work great (as long as it is not an N router you should be fine)
i know us robotic routers work great

thats just my thoughts though
you can get what you want

You should buy a WPN824 Netgear router. Its a little pricey though. However, it is an excellent investment to make. I'm using that right now, never had any problems and running latest firmware released two weeks ago. =)
