Re: Intermittent no broadband (upstream not locked)

Again today, I lost broadband and the light flashed on the Samsung TV STB.

Now, the broadband is now back as is the light steady on the cable box.

My levels are as follows on the modem:

Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : 1.0 dBmV
Downstream SNR : 39.8 dB
Upstream transmit Power Level : 54.0 dBmV

I did notice that if I remove the splitter and connect the modem directly to the wall then it works fine. I do have another splitter and this produced the same results...

So, I am now thinking that I am on the threshold of losing my service due to cable modem levels and the splitter pushes it over the edge. Does this sound plausible?

It's working now, but it seems to go down for hours at a time every other day. Anything I can try before I book an engineer?

Many thanks.
I'd get the engineer in if I were you, you seem to have diagnosed the problem at the splitter, let them work out how to fix it.
