The FEC & CRC rates shouldn't be negative, since that's impossible... Most likely just UVRT being stupid since your error table is clean.
However, overall, your IP Profile tab, error table and bitloading graph all look good. Better than mine in fact, and I max out my 12 Mbps connection.
Have you tested the speeds hardwired directly to the gateway and not wireless? Tested using more than one system? Tested with another wired/wireless router set to DMZ Plus mode?
He cleared his error table within 2 seconds of showing it's reports. UVRT probably got confused when he did so and showed those negatives.
I suggest you post another error table that has a longer history than two seconds since it's hard to see what's actually going on.
