I beg to differ with EricT, but I've found DLink to be an outstanding product, for routers (the DI624), PCMCIA adaptors (DWL G650) and print servers (DP350G). No muss, no fuss. They all installed without problem, if anything the installation procedure was too automated and you learn nothing about the machine in the process.
Its played very well with the remnants of my previous NetGear network, primarily card adaptors and print servers.
The signal is generally excellent throughout a good sized two story house, despite the lower floor (where the router is located as its the coolest and least dusy room in the house) being concrete block.
I've torn the system down several times since, reassembling it was even easier and quicker than the first. When I had to include a HP7000zt with a BroadCOM internal wifi, no problem, it hooked up flawlessly (at least once I remembered I had to turn on the wifi).
I don't know what problems EricT had with DLink, but I've had none. Even Technical Service has been excellent, answering problems relatively quickly even helping out on problems not directly related to their router (getting two machines to see and talk to each other over the same LAN, eventually it turned out to be a number of minor problems with the HP and BroadCOM combo).
I even got a heck of a package deal, though that's no longer available.
