I just purchased a new router (Buffalo WZR-HP-G300NH) and setup our router in a new location. I'm running the stock firmware 1.72.
Between my PC and the router there are several walls and a ceiling. The router is sitting in the basement which is mostly directly underneath the rest of the house. The router sits close to the basement ceiling--the floor of the rest of the house. The router appears to give out a fairly strong signal, however, the Internet tends to cut out from time-to-time. I wanted to determine if it was our new router or the ISP that was at fault, to do this, I ran a ping -t to see if I'm getting a steady response from the router.

Other related symptom -- our phones randomly leave our WiFi for the 3G network despite the 3 bars of wifi.
What could cause such a sudden degradation of quality? Could the router placement be bad? Should I find a better place for the router? Is the router itself faulty?
If you have an XP laptop, try using NetStumbler, as it can shows SNR values. – paradroid – 2010-10-11T01:42:52.073
