Hi guys,

i recently extended the coaxial calbe from the socket to cable modem (around 3 months ago), at the time i was on the 10MB service, however i upgraded to 20mb service couple of weeks ago and seem to notice some problem with the modem Downstream Frequency and upstream power levels.

Downstream Frequency: 315000000 Hz
Downstream Power Level: 2.8 dBmV
Signal to Noise Ratio: 37.9 dB

Upstream Frequency: 25808000 Hz
Upstream Power Level: 60.5 dBmV

seem to problem with both the down freq and upstream power level, i was under impression that down freq should be around 333000000HZ and powerlevel aunder the 60 dbmv.

i used high quality cables when i did the extension FT100 coax from maplin and also used Gold plated F connectors. the problem is wired coz i never had this problem when i was on the 10MB service only when upped to 20mb service this seem to be a problem?

my cable modem is : Scientific-Altanta WebStar Cable Modem

any help would be greatfull, thanks
