Upstream channel modulation keeps changing after local outage

[ic2]

Thats it really, had an outage in WD3 today and apparently fixed by 15:00; this was the status at 17:55

Upstream bonded channels

Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID

1	60300000	47.3	5120	64 qam	1
2	53700000	47.8	5120	64 qam	2
3	46199903	47.5	5120	16 qam	3
4	39400000	47.3	5120	64 qam	4

This is what it is at 18:00

Upstream bonded channels

1	60300000	47.3	5120	32 qam	1
2	53700000	47.8	5120	32 qam	2
3	46200000	47.3	5120	32 qam	3
4	39400000	47.3	5120	32 qam	4

and this now

Upstream bonded channels

1	60300000	46.3	5120	32 qam	1
2	53700000	46.5	5120	32 qam	2
3	46200000	47.3	5120	16 qam	3
4	39400000	47.3	5120	64 qam	4

should i just monitor it and see if it settles down?

You are getting timeouts because your modem is failing to keep a network lock. In some cases the problem is in the home, so power off your hub, check that all connections between the hub and wall socket are tight and power on again.

Will do. Thanks 

[lotharmat]

How's it doing now?

[ic2]

Hi

it behaved itself overnight and channels remain at 64 qam, the cable to the back of the modem needed a good tightening.

[John_GS]

Hi ic2

Thanks for posting. My apologies for the broadband issues. 

I've ran a system check and can see your downstream channels are out of spec. 

This needs a tech to attend the property so will PM you now to assist

Kind regards,

[Robert_P]

Sorry you haven't received the Private Message from John, I will pop one over to you now.

Looking forward to your reply.
