Virgin Media cable broadband. Max internal length for cable runs?

[bgowland]

This isn't specific to npvr, I was just wondering if anyone with a Virgin Media cable installation can advise on internal cabling.

We had a cable system installed yesterday and, to save hassle, I told the engineer to install the cable modem just inside the entry point behind our TV - this is fine as I have internal UTP cabling and a bit of juggling (cables, my own hub etc) means everything is fine. It occurs to me though that I might want to relocate the cable modem upstairs.

So...the modem is attached to a splitter on the main cable using co-ax and F connectors (I think). and I figured it would take a 30m run of co-ax to relocate. Anyone with Virgin Media cable broadband know if that seems like a reasonable run? It seems to me there shouldn't be any major problems but I don't want to fork out for a length of cable and connectors to find out it messes things up.

Cheers,

I did a similar thing, original virgin install was cable tv in the lounge and modem on the first floor. i got rid of cable tv then relocated everything to the loft. i removed the splitters so coax into house went directly into the modem. i had to add maybee 5m of cable to do it, but since being with virgin (9 years) ive only had one connection issue when my modem shat itself and needed replacing.

So where was the entry point - I'm assuming it was downstairs and they originally ran internal coax for the modem to upstairs?

I don't have Cable, but I doubt if 30m will be a problem. I've seen much longer co-ax runs with TV, 100BaseT, IBM 3270, etc. Just so long as your cable isn't stressed and the connections are properly made.

Ah, OK. Problem solved I think. I was having a bit of a senior moment trying to get my head around things. :o

The thing that confused me was the 'instructions' to the customer are that the entry point to the house should be within 1.5m of where the 'equipment' (internal terminating box) is to be located. I couldn't work out why it was such a short distance...I realise now the guys who put the external cable in only leave that much (or perhaps slightly longer) spare for the internal installation guys to work with. Doh!

I'm sure I had a brain earlier this week - perhaps I left it on the bus.

Yep - thank goodness for Quantity Surveyers
