Re: Please take a look at CM-1000 modem signals & error log and advise. Thanks

The upstream power is on the low side, especially on channel number 3. The CMTS / system may be having some difficulty hearing the modem with it being like that. Try power cycling the modem to see if it will range for / lock on to some different upstream channel frequencies.

OK, 

I'll power cycle when I get home from work. I did a reset of the modem when I noticed the errors in the log but that didn't help. Thanks

EG,

So I did the pwr cycle, still same errors. I'm not experiencing any issues orther than the logged errors. No modem restarts or dropped connections. Keep a watchful eye or what? Thanks

Can't see your pic for some reason. You could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.

O/k. If you are not actually experiencing any connectivity problems, I wouldn't sweat the log entries. Good luck !
