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

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.

I got:

what is your advertised speed?

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.

The advertised speed is 6 MB. I have called tech support and they should come tomorrow and check out the problem. I will also do a tracert.

no need to do any tracert... your power level is too low. should be around -+5 from "0"

how do yuo guys check the power level??

that link will sometimes take you into your modem diag screen.. I know motorolas do..

qwazzy im sorry to hijack your thread but do you guys see anything wrong wiyh mine? ..Thanks sava for answering the question.

nevermind everything seems to be in order according to this page
