Re: Signal Levels

Engineer number 3 came today, did more than the previous 2.. checked out my signal levels on the modem, V+ box, isolator, omni, and in the pit.. then said that there was a problem and he called networks.

Networks have just been, and sorted it,

by the time I get a 4 way splitter fitted to eliminate the 2 way splitter, I should have a perfect signal level of around 0 dBmV

modem levels are now,

and V+ box is -8 dBmV, -5 dBmV upstairs without the 2 way splitter.

So now im wondering if the previous 2 engineers were just giving me rubbish about calling networks, as they was supposed to of been down twice previously and didnt make this fix, so now im going to persue a complaint, why 2 engineers, and 2 "supposed" networks visits could not fix this problem and I was given rubbish about my signal levels being fine and nothing could be done.

When this engineer managed to get it fixed, with 1 call to networks and spent a lot more time investigating the problem.
