Re: Questions about SB5100....
If your normal range was "50-58dBmV", there is your issue. Your upstream should be kept below 55dBmV and shouldn't slide that much as it appears to. Preferably, you should try to keep it between 35-52dBmV. If goes above 55dBmV, you can see disconnects.
Check all cables, cable connectors, and splitters for issues. Also if possible, you should have one splitter from when the cable enters the dwelling. One side to the modem and the other to a TV or additional splitter.

1 edit | No splitters really...
But there is one other thing I forgot to mention that could be an important piece of information: this is a wireless connection. The cable from the cable modem goes to a little "power injector" and then goes from there to a wireless antenna mounted on the outside of my house. It's my understanding that the power injector provides power for the outside antenna... That's the only "splitter" type thing in the line though; no TV comes over the same line or anything, it's just for internet.
So I'm not sure if that has anything to do with the strange power readings or not, since it's not your "typical" cable modem installation  Could that be why my values slide so much... due to the fact that my link is through the air..?
thanx for the reply, I will keep an eye on things, and possibly send a message to my ISP regarding the upstream power reading depending on what you and others think...
thx! |
