Could my Gaming issues be due to modem signal levels ?

[Muppetz]

My general surfing tends to be ok (apart from the odd time when a page will take forever to appear, as though there is a pause on the line) but gaming (xbox 360) is pretty poor with lag/poor speech etc.

I had a look around the forums and it seems it could be to do with my modem signal levels ? would they have this kind of effect ? here are mine currently :

Downstream Lock : Locked
Downstream Channel Id : 1
Downstream Frequency : 586750000 Hz
Downstream Modulation : QAM64
Downstream Symbol Rate : 6952 Ksym/sec
Downstream Interleave Depth : taps12Increment17
Downstream Receive Power Level : -13.0 dBmV
Downstream SNR : 31.0 dB

Upstream Lock : Locked
Upstream Channel ID : 4
Upstream Frequency : 46200000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 42.0 dBmV
Upstream Mini-Slot Size : 2

Upstream seems pretty stable, but downstream is fluctuating around 12.8 up to 13.4 so far... - the sticky at the top suggests this might be a problem, is it worth calling support ?

Ok, so I might have done something clever or stupid... I removed the 3db Attenuator on my modem cable and now my figures are :

Downstream Lock : Locked
Downstream Channel Id : 1
Downstream Frequency : 586750000 Hz
Downstream Modulation : QAM64
Downstream Symbol Rate : 6952 Ksym/sec
Downstream Interleave Depth : taps12Increment17
Downstream Receive Power Level : -10.2 dBmV
Downstream SNR : 32.1 dB

Upstream Lock : Locked
Upstream Channel ID : 4
Upstream Frequency : 46200000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 42.0 dBmV
Upstream Mini-Slot Size : 2

According to the sticky that should be better ? or did should I put it back ? LOL maybe I should leave well alone !

Downstream power seems to be going up by the minute... 10.5 just now...

Unless you are getting disconnections I highly doubt it has anything to do with powerlevels.

How are you connecting the xbox to the modem? How many people are using the internet all at the same time?

[Muppetz]

Via a Linksys Router, and with no other devices/users using the connection at all.

I will try it connected direct to the modem tonight and see if that helps at all.

looking at the levels after you removed the attenuator you didnt ever need it. Your levels are now within the ideal zone.

That's what I thought, but wasn't entirely sure !

[LaineY]

i would personally tech his call if he phoned us.... ideal levels are -12 to +12

however i always go with -10 to +10

some regions can vary
