Hi there,
We had 20Mb broadband in our house running fine for a couple of months on its own (19.5 Mb off giganews) but upgraded our package to include tv and phone and since then have been getting fairly regular dropouts.
At first I thought it was the wireless router but after finding this forum and reading the signal noise thread I think it could be related to the upstream power level. It was actually at 59dBmV earlier, but as a test I disconnected the tv cable and it dropped to 54dBmV, since screwing the tv cable back in its only gone back up to 57.5dBmV (pasted below)
Could the 59dBmV explain the dropouts? and can I get away with 57.5, connections not dropped yet but its only been about 30 mins. I've gone round and made sure all the connections are tight, and replaced the old looking splitter/filter with a new one that came with the tv package.
Any help is appreciated.
Cheers
Martin

EDIT:
One other thing I just remembered, when I was trying to get the set top box activated it didn't work the first few times, the lady said she would send a stronger signal down and then it started working, I don't know if that was just a stronger activation signal or what though.
Cheers
