Lost my internet service

I can't really tell by the picture of the modem of what version you have an f series or g, but I can tell you this for personal experience that the westell 6100 F series is junk. I went with westell 6100 G and my works pefectly. Verizon admitts at www.dslreports.com they have trouble with the 6100 F modem. What verizon said the new firmware was to blame on the 6100 F.
I would like to add that my friend had the exact some problem, he got he G series, and it cure his.
