Hi,

I'm on the 10mb service, running on an Ambit256, Southampton area.

My modem stats are as follows:

Cable Modem Downstream
Downstream Lock : Locked
Downstream Channel Id : 206
Downstream Frequency : 306750000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 6952 Ksym/sec
Downstream Interleave Depth : taps12Increment17
Downstream Receive Power Level : 15.8 dBmV
Downstream SNR : 41.1 dB

Cable Modem Upstream
Upstream Lock : Locked
Upstream Channel ID : 2
Upstream Frequency : 35800000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 5120 Ksym/sec
Upstream transmit Power Level : 40.7 dBmV
Upstream Mini-Slot Size : 4

Now, I'm having NO issues at all, I get full 1.2MB/sec download speeds all day and have no ping issues, but I see that the downstream power levels are around 15 which is very high from what I've read on here.

As I have no issues I'm reluctant to call out an engineer, however I do have a few cable splitters which attenuate 3db at each output, so was wondering if adding a splitter to the cable input would bring levels down to an acceptable level.

Thoughts? Or should I just leave it alone, if it isn't broke etc...

If it ain't broke...........

If you do end up having problems you would need that downstream bringing down. Personally I'd like my power levels within spec with leaway allowance.

Some modems have been that high for years with no issues, i'd leave it alone.

Agreed with the above and now you know about it, if it goes off, just drop the power .. quick fix.
