Re: Unusable connection with lot of dropouts & high latency

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?

Re: Unusable connection with lot of dropouts & high latency

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)
