RCS Partial Service and Lost MDD Timeout - another one

[NondescriptUN]

New to the forums, but taking comfort in the fact I'm not the only one having this problem.

I didn't want to spend 2hrs doing basic support with the voice team, so here I am attempting to post logs that others have.

My internet has been dropping out all the time for the last week, it's driving me completely up the wall. Also like many others, my Asus AC86U router has been complaining about the DHCP.

I just rebooted a short while ago so here's a few logs. If anything else is needed, I can provide

SNR problems on downstream channels 11 & 12.

Check with Area faults on  0800 561 0061 or if you have a VM landline 150

If no faults found:

Call Customer Services on 0345 454 1111 or if you have a VM landline 150

Thanks a lot.

I rang customer services, who were really great actually, and they're sending an engineer.

It turns out the cable outside the house was damaged a few years ago but taped up, so perhaps worth just replacing it and seeing if that improves things.

Thanks for your post on our Community Forums, and a very warm welcome to you @NondescriptUN.

Pleased to hear that we've been able to assign you an engineer.

Do feel free to update us on the visit
