Re: [TWC] RR terribly slow

it would be nice to know what frequencies your modem is using along with the SNR.

Could you copy and paste all of the info as power level does not give enough info alone.

example from my modem stats:

Downstream Bonded Channels

4 Locked QAM256 3 795000000 Hz -5.0 dBmV 36.6 dB 211 0
5 Locked QAM256 4 801000000 Hz -5.3 dBmV 36.4 dB 365 0

I am curious to know what upstreams your modem is bonding along with downstreams. Curious to see how TWC set up the upstreams in your area to see how much bandwidth they have enabled on the upstream.

I am in Fairport, NY. Periodically our connection slows to a crawl and stays slow. When I re-boot the modem I get a fast connection that may stay fast for days to weeks. I wonder if this is a problem TWC will fix if I request it. Otherwise it is easier to just keep re-starting the modem.

You just need a new modem if a reboot clears your issue for X amount of time.

If there was an area problem, a reboot will not resolve, same as a line issue.

where are you located? you have an interesting setup with 549MHz not being used for DOCSIS. Maybe in your area 78 (549MHz) is the amplifier pilot channel that keeps the main line amps balanced.

I would guess you are somewhere in NY state? I have seen posts here at dsl reports that show the 23.8MHz and 19MHz channels being used for upstream in NY state including NYC.

Very interesting, I never would have guessed that. It does not make sense but I will get a new modem, they always seem glad to replace modems. thanks.
