SB5101 Restarts Intermittently Only w/ Router
My 6-month-old Motorola SB5101 modem is restarting frequently, but only when connected to my Netscreen 5XT firewall/router. A direct connection to my laptop works without apparent failure. Any ideas why this would happen?
This configuration has worked wonderfully for my first 2+ years with Charter Internet. However, the company came to my house, unprompted, the other day to fix some "noise" and things have gone south ever since. For example, two weeks later, my modem was mysteriously "reprovisioned" (on Memorial Day?!) we ended up on a new IP block, and certain ports are now blocked, like SQL Server (1433). It took six days and a trip to their office to get a straight answer re port blocking, so I've lost faith in their support. Add to this that they've begun pushing "business" upgrades and "insurance" while threatening onsite service fees because I use my own modem. I won't speak with them again until I know what's going on.
I have two identical Netscreen 5XT firewall/router appliances and have swapped them to verify performance - both exhibit the same issue. It's safe to say they're working as expected.
Also, I've logged roughly 48 hours of modem activity in both configurations - SNR, USPwr, USFreq, USChan, DSPwr, DSFreq - and graphed them in Microsoft Excel but don't know what I'm looking at. I can share, if it is relevant.
Thank you so much!!!
