Signals- Are they any good?

Hi all,

Just bought a new SB6121. Here are my signals (sorry about the formatting, couldn't figure out how to do a screen shot). Does everything look good? Getting pretty good speeds right now. Thanks for all your help, Jenn.

Signals are generally good. Downstream SNR's could be 1-2dB higher. How long is the uptime? Your correctable/uncorrectable counts are a bit on the high side, although the unerrored counts are also very high, so it's probably been a few days and/or alot of data in a short time.


Uptime has been about 4 days. Haven't had any problems yet- no time-outs, reboots or anything like that. I checked the logs and there hasn't been any entries for several days. Speed has been consistent (about 50 down and 10 up). I bought the SB6121 because I heard it's a pretty good modem. Thanks for your input.
