From a non tecky perspective, I,ve tried all the vm supplied routers,
The Netgear WNR2000 was good on a wired connection, was good gaming wise, but the wireless performance was far from brilliant, with frequent drop outs.
The D-Link Dir 615, I thought was a heap of junk, but the wireless performance was very good, and easily the best out of a bad lot (if wireless is your bag)
I have a Linksys WRT610N, (xbox friendly) and its pretty good at most things, the only thing I,m not so keen on is the limited Qos functionality, but its easy to use.
(the other concern was that it got hacked within 24 hours of setting it up, probably my fault because I didn't change the default router login username and password), One hard reset later and normal service was resumed.
I get a good wireless signal all round the home, even after turning the broadcast power down to medium, but from a wired gaming perspective I think the netgear might have it beat.
Like I mentioned, I,m no tecky just an average Jo Shmo, drifting through life gaining just enough knowledge to be dangerous.
