I have been using the
D-LINK DIR-655 Xtreme N Gigabit Router 802.11G/B Draft N Wireless Router Triple Antenna QoS for a bout a year.
I have 3 workstations direct wired to it, and varios combinations of
an HP wireless N laptop, A wireless N Macbook, an ipod touch, an xbox 360, a PS3 and an asus netbook(N as well I think)
On wireless. Two teenage boys, Me and my poor long suffering girlfriend, but all very active net users .
I came from a wrt54gl as well. And it would conflict with wireless phones, especially on the xbox.
This one seems fine. It comes with nagware home networking software that I stopped using.
I dont do anything technical with it. I use this and Norton to protect my PCs and have no issues at all that I have noted from intrusions(ADSL connection)
looking on the NCIX forums for this thing, there does seem to be an issue with some of them, loosing connections. I don't leave it on 24/7 so I don't know if I would see that or not.
All in all I would recommend it. It reaches from upstairs middle of the house to anywhere in the yard with the macbook no problem.
