Isolator Problems
 
My internet has only started to work when I connect the modem directly the black cable that goes outside, bypassing the white cable and isolator.
Ive tested it all using a spare white cable and the same isolator and it still didnt work which leads me to believe that its the problem.
Do I NEED the isolator or can I just go and buy a converter so I can attach the black and white wires directly?
If not then whats then whats a good model to buy (i don't want an engineer out)?
I have a VQ302LC at the moment and its huge.
I don't need a splitter as I only use the internet is this room.

Thanks for any help

Ring VM, that is nothing that you should really be messing with in case something gets damaged or goes wrong. Get them to put it right.

Yes, looks like your fiddling around:

http://www.cableforum.co.uk/board/62...isolators.html

has caused problems for you (and perhaps others).

Perhaps you should get your supplier, Virgin Media, out to return your installation back to the correctly installed state.

PS Why don't you want an engineer out?

If there's a problem with VM's equipment, replacing it will be free. However if you've broken it, then it's your own fault and you'll have to foot the bill.

Could also be that the signal amp in the street cab is failing, and removing the galvanic isolator increases the signal by about 3.5dB (if memory serves) allowing the modem to connect. This WOULD be a VM fault.

I haven't fiddled with anything, I had a look ages ago to see what was inside and weather anything could be replaced.

And i thought it would be easier to just buy a new one and fit it myself then get an engineer out.
It would seem like a waste of time for him.

I looked because it was broken, I didn't break it because I was looking.

I dont think my internet has been as fast as it is now without the isolator.

In your first post, you said that you had made changes to the installation. Now you say that you haven't changed anything.

Which is it? Is the installation the same as originally installed or not?

It was broken first so being pro active I investgated and found the problem myself.

So you DID fiddle. You 'made' a repair without the training and knowledge to do so and are now on here looking for help instead of doing what you should have done in the first place - call out Virgin Media to repair their equipment which you say was broken.

It is not pro-active to fiddle around with somebody else's equipment and potentially make the situation worse.

I didnt make a repair, I found the problem.
Ive saved the engineer time because he knows what to replace now.
It is proactive to 'fiddle' with equipment if it means the problem can be found easier.

I apologise but we will just have to disagree on the wording of what you have done and whether you have the right to alter any of Virgin Media's equipment.
As you are now suggesting that an engineer is on the way, whereas you previously said you 'don't want an engineer out', then we will establish what the problem is and hopefully you will have reduced his problem determination and fix time.
I'm sure you'll let us know.

when i worked for telewest / ntl the galvanic isolators only gave a 0.1 db loss there is no real easy way to tell what your signal strengh is as the installers carry swires meters to measure db and snr from using the meter they can check signal to your propety and to your equipment to see where the fault is. give them a call to there cancellation department as they have the power to authorise a repair technican to call as soon as possible

Hi Paul :)

As the original post in this thread was made over half a year ago I would hope that the OP has got things sorted by now, even Virgin can't be that bad :D
