Sorry = darn spell check got me!
Router model is WRVS4400N
I did some testing with an old one of those a few months ago.
Turn off wireless N, let the router auto-select speed, broadcast SSID and maybe even turn off WPA to start with.
In my hands, that router did ok with a 1.2 NC, but it was a better G than N router.
My particular unit was given to overheating (esp. the gig chip) when I first set it up, and I replaced it very early on. I just happened to have it in the house still and tried playing with it.
