After moving to a new location (moved to an older house as opposed to being in an apartment), SB8200 can’t establish a downstream connection. Getting errors very similar (almost exact same status message) to the ones in the following post:

I also am getting multiple instances of “UCD invalid or channel unusable” and “No ranging response received.” Modem has worked for 2 years and has only started failing after the move. Checked and the warranty has expired in March of this year. Any suggestions on how to fix this issue?

Thanks!
