slow comcast connection :(

Post by qwazzy »

I have a slow connection. These are things from my modem, althought I have no clue what they are. :rotfl:

Downstream Value
Frequency 717000000 Hz

Signal To Noise Ratio 32.1 dB

Power Level -15.3 dBmV
The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading


Upstream Value
Channel ID 10
Frequency 23000000 Hz
Power 53.3 dBmV


What does this mean? Whats the problem?

run the tcp optimizer and set to optimal settings, followed by a reboot.
then do a nitro test- http://nitro.ucsc.edu/ post under the statistics tab.

the packets being retransmitted means faulty cables or EMI
do a tracert and post your results.

Power Level -15.3 dBmV
this is too low.. call tech support have them come out and adjust this to 0 or as close as they can get it. Once you get on the phone with them they can see this low power level from their end too so just explain that.
