SB8200 Locks up and must be power cycled

Those tend to indicated a line issue. Tough to say 100% without the cable connections page info. It shows upstream/downstream information. 

Here’s the downstream/upstream values. I was arranging the coax feed an disconnected it. The MODEM locked up and I had to power cycle it. All 4 lights are on solid. I would think it should recover from a coax disconnect. My old Motorola Surfboard would. The SB8200 runs pretty warm. I don’t know what’s the normal warmth but again, it’s warmer than my old Surfboard which was actually not warm at all.

To begin isolating the issue, please connect a computer directly to the modem using an Ethernet cable and monitor the connection to see if it drops. This will help determine whether the problem lies with the modem, the router, or elsewhere.

If the issue persists even with a direct connection, we can proceed with checking the cable signal levels within the modem . If the signal levels are out of the acceptable range, they can lead to the kind of connectivity issues you're experiencing.

When the signal levels are within the recommended range, your modem can maintain a stable, high-quality connection to the internet

Please refer to the link below for instructions on how to check your cable signal levels:

If you find that the signal levels are not within the recommended range, we suggest contacting your Internet Service Provider (ISP) to have them reviewed and adjusted as needed.
