Re: Network Routing problem

I am using a wired connection but i cant seem to connect to some websites, for instance www.x.com done a ping and tracert:

C:\Users\yonat>ping www.x.com

Pinging x.com [104.244.42.193] with 32 bytes of data:
Request timed out.

Does anything look wrong with this?

    I'd be concerned about the Post RS Errors aka uncorrected errors affecting all 3.0 Downstream channels,
    if these numbers are still increasing the problem persists.

    The 3.0 Upstream power levels are testing the upper limits, this matters because it is the measure of how high the VM Hub has to transmit in order to be received at the street cabinet.
