Is 1m or less pre-terminated coax cable for between wall outlet and hub 5 please?

Hi,

Just wanted to try a pre-terminated VM coax cable between our white interior wall outlet and our Hub 5 (in modem mode) in the hall (doesn't do any Wi-Fi duties obviously blush) as just wanted to cross it off my list of possible locations for a poor connection (existing cable was engineer fitted in 2011 and regularly checked its tightly screwed up)?

Cheers in advance.

Dave

    Pre terminated cables are available.

    But do your Upstream / Downstream stats reflect a current problem with Signal Levels / Errors / Modulation modes ?

    When was the last time you rebooted the HUB?

    The downstream power levels are a touch high (-6 to +10 dBmV is considered in spec).

    There are way too many errors on the some downstream, as well as TX timeouts on the upstream channels.
