RCS Partial Service and Lost MDD timeout errors

[steverosetti]

Hi

Having issues over the last week with the Hub rebooting and loss of internet.

This is causing a lot of frustration as my wife works from home.

Can anyone take a look and let me know how to solve these problems.

Apologies for the delayed response, steverosetti, how has your connection since your post?

Hi.

The connection appears stable at the moment.

The Hub hasn't rebooted itself at all over the last few days.

Thanks.

[Corey_C]

Thanks for your reply and update, steverosetti. Glad to hear things are being more stable.

Cheers,

The postRS errors look bad - but then so do mine and my connection is pretty stable!

Hi 

Can you post your upstream stuff to not just your downstream. Looking like bad line with the post rs errors. 

Need to see your upstream stats

Hi 

Well T3 timeouts problem with upstream. 

[RockerSBM]

Hi

you getting random drop outs too?

[steverosetti]

Hi. Yes. Sometimes it’s like everything is on pause and nothing loads.
