  • SB8200 intermittent internet connection and send led light on the modem is blinking constantly

Hello, 

Yesterday afternoon my internet cut out and I have been unable to restore it. I checked with my ISP and they aren’t showing any outages in my area, and tried resetting my network on their end but are unable to communicate with my modem. The upstream light on my SB8200 consistently blinks despite resets and factory resets. I logged on to my Connection pages and Event Logs.

On my connection page it shows Acquire Downstream Channel-813000000 Hz -Locked

Connectivity State-In Progress- Upstream Parameters Acquired

Boot State-In Progress-Unknown

Configuration File-In Progress-

Security-Failed-BPI+

DOCSIS Network Access Enabled-Denied 

 

My downstream and upstream bonded channels seem to have proper power and SNR outputs.

On my Event Log 

Event Level 3 with description “No ranging response received - T3 time-out”

Event level 5 with description “B-INIT-RNG Failure - Retries exceeded”

 

Thank you for any help!

In this case for intermittent connection issue we can only check on direct connection since SB8200 is just a cable modem. Basically intermittent connection or no internet access occurs usually out of cable signal level, out of acceptable range and it will be resolved after the power level are adjusted by the service provider.

So for this we need to check the cable signal level to confirm what causing this issue to proceed further.
