Well I've had very poor results with d-link wireless gear (only wireless though - I've got a 4 port active KVM and that works great!) And when I say 'poor results' I mean that with the kit of equipment we purchased at the time, three of us spent several hours each trying to set up a couple of routers and bridges. After we'd all failed, and none of us are idiots, we figured that someone should call tech support (at the time there was a free number you could call) and I drew the short straw so I had to make the call. Well after more than two hours on the phone (not counting being on hold for 30 minutes) and still not being able to sort it out we took all the junk back to the store and swapped it out for linksys - only coz that's what the shop had in stock. And ever since then I've pretty much used linksys exclusively. The "blue brick' series of linksys gear just works, though I am not a fan of the newer models.

Linksys firmware is not too bad but a little limited - you can't, for example, change your subnet mask on a WRT router which means that you can't span subnets...linksys firmware will not assign static IP addresses via DHCP.........but DD-WRT firmware on linksys hardware is bloody fantastic!
