readings from cable modem router

Downstream Lock : Locked
Downstream Channel Id : 0
Downstream Frequency : 402750000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : -15.6 dBmV
Downstream SNR : 34.4 dB

Upstream Lock : Locked
Upstream Channel ID : 4
Upstream Frequency : 37500000 Hz
Upstream Modulation : QAM16
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 43.5 dBmV
Upstream Mini-Slot Size : 2

are these ok for the speed

downstream power is too low i would say, but if your not having any issues then no need to call vm.

what should the ideal downstream power be ?

22-10-2009, 18:11

0 ideally -15 is mega low ..

doing the speedtest getting various speeds from 12 mb to 18 mb - will monitor it and see how it goes.

A low power level is an indication you are on the wrong tap in the cab and would need a technician. Jump on the newsgroups and they will book one for you, without the need to call up. Rather book it now than suffer slow speeds or connection drops.

Just make sure the modem doesn't have an attenuator on the back, between the coax and the modem. If it does, just take it off and see how the power levels are.

noticed the modem had an attenuator plugged in, took it out now get these readings

looks good to me

Excellent, much, much better. You're aiming for -10 to 10 but the targets are different depending who you speak to .. -5 to 5 is a clear winner.

Much better how about the Upstream.

however doing the speedtest not getting a full 20 mb - getting from 6 - 14 maximum

Speed tests suck, download from
http://gamefiles.virginmedia.com .. get two fiels running and add the speed together.

ok

downloading 2 files

one file is 600 MB and second one is 1.1g

getting 800 kb/sec on first one and 600kb/sec on second one

I think Moldova is your best bet here
