D-Link just to say my 2 bits for/against.
I love the DGL-4300, (B/G) the power adapter cooked itself after 3 years in service and a combo week long server
host + 18 hours of Xbox Live + internet video streaming going on at the same time. Got a new adapter, it's still
working.
Have a USB adapter, a couple PCMCIA cards, and misc equipment that is all D-link but was current G tech at the time.
All of it works fine.
Bought a DIR-450... (B/G) can't even remember how many of those I traded out before CompUSA folded.
Probably around 10, and the one I have still is buggy as all get out.
Got a DIR-825 (N and B/G) recently when the previously mentioned adapter died, it had major issues
with trying to get port forwarding to work. It basically ignored the entire list of rules. It was the router, I did plenty of testing.
Returned it to get...
A Linksys WRT320N (N and B/G) and it seemed to work ok, up until it decides to lock you out of the control panel at random
after about 3 days to a week of use. DD-WRT kinda supports it, but I'm waiting till it gets out of the beta support to flash it.
The best place I know of for help on all things related to broadband and equipment, is the DSL Reports forums. It used to be Broadband Reports, but every major brand usually has official support reps watching their sections. Most of the people are willing to help solve issues and very knowledgeable. If anyone can find a solution it'd be there. Building repeater antennas and boosting cellular signal strength with coffee cans and used sat dishes is regular stuff around those parts.
