This number is huge and indicates either noise on the channel or, more 
likely, an issue in your card/antennna cabling.

These are likely the same issue.

I'd check physical setup and/or look for noise in your environment (is 
there a disk in this machine?)  Basically isolate potential noise 
sources to rule out external causes.  With zero info to go on everything 
is a guess.
