if freq 299mhz -6 its amazing you can even watch tv channels at 609mhz as they'll be -10 or worse
Hi, thanks for the reply.

when the engineer arrived, first thing i did was explain how when it was originally installed i was recomended a replacement cable which never happened and that this had been an ongoing problem.. then he plugged his signal meter into the broadband modem cable, and went to check the line taps... a while later he returned, and said theres some corrosion where a previous engineer hadnt closed it up properly and that he would get networks onto it... then logged onto the Superhub, disabled some of the features like the firewall, then looked at the status page with the signal levels.

When he said he had this time put a tag on it to make sure another engineer doesnt move it down. I know he moved it again because the tv cut out for a while.

So I asked if theres any way I can get another cable put in, and he told me that they will only do that if it is like worst case scenerio then went on to say that using the thicker drop cable is more a london architecture, not round here.

Then he left, wasnt until after i checked the signal levels and theres barely any improvement.. i dont know what they should be but he might as well of not turned up for the difference its made.. but there wasnt much else I could do lol

So you think I should phone back again? I know im not happy with it, the improvement is barely anything. TV Channels work ok, but i admit occasionally i do get interference on the channels like you do on freeview with a weak signal. Broadband speed is more erratic if nothing else.

Also have a V box also, so 3 boxes and a broadband modem.

He never checked those signal levels, just the signal level on the broadband modem.
