Superhub : No success in moving Superhub

[gavhen]

Hi,

I'd looked around on a few forums to find out whether it was possible to move the superhub as it's in a really stupid location to cover the flat, we don't get any signal in about half of it. Got the impression it was straight forward enough, went to Maplin, asked for the correct cable and connectors and explained it was for my cable superhub.

So I get home with my new 11m cable instead of the previous 2m, fit the connectors striping back enough to expose the copper as much as was done previously, and it doesn't connect through to the internet at all. Is 11m really too long for the signal strength or is there something else fundamentally wrong with what I did. Are there any kind of checks?

If it helps the cable that I bought is "Banbridge LC5509 OFC Copper Triple Shielded Digital Coax Video Satellite Cable"

Cheers.

Did you make sure you left the outer metal shielding exposed so it contacts the outer part of the connector when you screw or pinch them onto the cable? Make sure the shielding doesn't touch the inner copper either, or you'll short it out.

[gavhen]

Nope, that would have been good information to know, it won't have shorted but it probably isn't exposed much either, took most of it off.

[GavChap]

What you need to do is strip the outside plastic off, peel back the shielding, so it goes over the outside plastic, then expose the inner copper leaving a bit of plastic inner coating so it's long enough to become the inner connector, and push or twist over the connector so the outer copper shielding is stuck between the plastic and the metal connector making the outside connection to the nut.

Ok, cheers, I'll have a go and report back, help much appreciated.

Got a multimeter? Do a cable test, then check modem stats. 11m of cable will never cause enough degradation to disconnect completely, though admittedly you are using the wrong kind of cable so it will cause more loss than normal.

Why not gt a long Ethernet cable and a dlink615?

[gavhen]

Glad to say after fitting it correctly it works! Thanks a lot GavChap!

Just relieved I hadn't wasted time and money there, I may have some degradation but at least we've internet everywhere in the flat now. Incidentally what cable should I have bought? I relied on Maplin shop guy to point me in the right direction when I explained what I wanted and I as far as I was concerned satellite cable coaxial cable was it. I chose the 'higher quality' one out of the two offered.

[qasdfdsaq]

While good quality cable won't cause any more loss itself, it's when you connect cable of different impedance together you get insertion loss and mismatch loss at the connectors between them. It's slight but measurable. IIRC VM coax and satellite coax have different impedance ratings, though I'm not completely sure these days - been a while since I used either.

[Edit] Maplin satellite cable is 75Ohm so you should be fine. Never mind, I was thinking of RG-58 instead of RG-59.

Ok, I'll stick with what I've got then, not worth getting some other replacement. Seems to be as fast as what we had before when close enough to the hub and we're not overly heavy users. Thanks for all your help!

If you ever have a Virgin tech around in the future, tell him you are thinking of moving your TV around and if he would be so nice as to leave you some cable. We had Tivo installed a while back and the installer saw we were using some non-vm cable to go from the box where the TV used to be to its new location and he happily cut us a length to replace the cheaper cable with. He got some biccies that guy.

Far better than paying £75 for a 10 minute job.
