how many channels

Hey, i am curious about something, my modem has 8 available channels but only 4 of them seem to be in use, im in North Bay, this is the report from my modem. Just wondering if it looks normal?

Some Cable users still see 4\1 channels for some reason (some other guys will be able to answer you better why).

Also, your upstream power is hitting the limit, which i believe is 52 dBmV.

Maybe you would want to look into that.

# of channels is dependant on what the local incumbent (cogeco, rogers) has active in your area. They have to swap/install equipment in your local area to support the higher # of channels.
When the local incumbent provides more channels, your modem will use them without start having to do anything.

Your upstream power level is very poor. Given the power level fluctuations thoughout the day, I would expect you to get a lot of disconnects.

It is my understanding that this is usually caused by high amount of noise in the line (i.e. caused by poor splitters).

Try power-cycling the modem (give it 5 min). If it comes back up with the same high power level, try plugging it in directly to the input cable line (without any splitters).

If the problem is still there, give Start a call and get them to send a tech over to fix this for you. If the problem is fixed, your splitters or one of the cables connected to the splitters are the culprit.

Ok, I'll look into that upstream issue.

Four channels here also and I am on Tek, my understanding is that Cogeco is only using four in North Bay.

so there was an unused splitter on the line i removed it and now the numbers look like this,

The upstream still seems a bit high, other than running a single cable, there is one junction on the line in the house, and/or rebuilding all of the connectors, i dont think there is much else i could do, is that number still high enough to have it looked at or should that be ok?

Also, im curious if anyone knows if the higher upload speeds are going to be available in the north bay area?

Well, its much better now - just keep an eye on it throughout the day. Could be that you just checked on it at a good time?

Try hooking the modem up directly to the cable before all the splitters - what kind of stats are you getting? If you're getting something much better than that then you probably should take another look at your splitters and cabling.
