Cox → Re: [AR] Long-term Issue in NWA

The only device that's connected to the Internet via the cable is the wireless modem/router. None of our TVs are hooked up to cable, as we use an outdoor antennae and we don't have VoIP. When DirecTV came in, they wired the living room and bedroom for satellite, apparently not using our houses existing cabling because it was either too old or not the right type. We got rid of DirecTV some time ago when we became cord cutters.

I am using the dish as a mount for an outdoor antennae and that connection uses one of the old DirecTV lines. But these Internet problems were happening well before that. I'm pretty sure the cable internet is separate from the satellite cabling.

So I have one cable modem plugged into a newly installed cable with little to no change in performance. I can't rule out a problem in the crawlspace. I'm wondering now if I should make sure there's only one dedicated line from outside that goes directly into my cable modem. Maybe old lines that may be still connected to a splitter are causing problems.

I would love for it to be that simple.

So you have wiring connected via a splitter your not using? That isn't good. If your only using 1 outlet for the gateway, then it should be a direct line from the ground block (outside) to the modem. Anything OTA should be on a different loop, probably the stuff DTV installed.

I looked around the basement and as far as I can tell, there is only one line from my modem to the box outside. No splitters. There is a cable hook-up in the main bedroom but it doesn't appear to have a signal.

Strangely enough, I saw a Cox branded repair vehicle in the area and I've just recorded the highest speeds I've ever seen.

It's a very curious thing.

I agree. I am stumped. It seems your speed problems aren't related to signal levels. atleast not in the way I thought. Anyone else have any ideas?

It's odd that the upper four downstream channels have such a large difference in SNR than the lower four channels. I wonder what the uncorrectable errors look like on those 4 channels vs the other 4.
