I just installed a new SB4100 to replace my original rented Motorola CyberSurfer non-docsis modem. Now my dl speeds are about 25% of what I had:
2877/112 kbps vron1.nj.home.com
717/116 kbps narltn1.nj.home.com
I checked the modem diagnostics at 192.168.100.1 and everything looks good: 32db s/n, -3 dBmV power level, 64 QAM (s/b 256?). My pings look good and have no rexmits on the tweak test.
An @home tech supposedly did a 'push' to my modem but this has not improved anything. The first tech said she couldn't access the Comcast network to do it. So I'm not sure they did anything. I am thinking about going back to the Cybersurfer. Any ideas what the problem is?
