You could try doing a software reset on the SB6120 (available via the web interface, e.g. »192.168.100.1/) and see if after that reset the LED on the cable modem doesn't come back up blue.

Either way, this kind of problem -- even sporadic -- is almost always the sign of vendor compatibility problems, specifically with regards to auto-negotiation. Even enterprise-level hardware has this problem, which is why many environments prefer managed switches where you can administratively set the speed/duplex on *both ends* (required! You can't set it on one end and expect the other end to work properly) to avoid this kind of situation. In other environments, auto-neg is the only way to get things to work. Go figure. :-)

Replace the Linksys with something that negotiates correctly with the SB6120. I'd recommend one of the HP ProCurve desktop switches, or a D-Link DGS-2205 or DGS-2205.

Finally, are you using anywhere near gigabit capacity through your cable modem? If not, then won't 100mbit full-duplex be sufficient? That's 100mbit up, 100mbit down by the way.

Have you tried resetting and restarting the modem? Go to »192.168.100.1 go to the configuration tab, then click on Reset All Defaults and then once the page has reloaded click on Restart Cable Modem. Let us know how that works for you... :p

Any way I can verify the LAN side connection speed other than the LED?
