Unusable connection with lot of dropouts & high latency

[SDESIL]

Hi,

Having horrendous connections issues last four to six months, continuous connection  dropouts & high latency. with "SYNC Timing Synchronization failures" "RCS Partial Service" & "No Ranging Response received - T3 time-out" errors.

had couple of engineer visits with out a luck. Where I go from hear   ???????

Post up the tables of data from the Downstream and Upstream pages as well.

Is the Hub in normal router mode or is it in modem mode?

What equipment have you got connected to the Hub on ethernet cables?

[SDESIL]

Thanks for your reply.

Hub 3 used to be in the modem mode (with a a Cisco device doing the routing) but now put back to router mode.

Most of the desktops and TV's are wired and testing done using wired devices. (also included todays BQM graph)

Hey SDESIL, thank you for reaching out and a warm welcome to our community. I am sorry to see you've been having some connection issues for past few months now. 

I've take a look on our side and I found an issues  which is an ongoing connectivity issues, so I need to organise a engineer visit for you. 

Please look out for the purple envelope I am going to PM you. Thanks
