Well, the engineer came... take a quick look at the power, said it was OK, and then said he couldn't do any more.
NTLs system upgrade this weekend means that he couldn't try a new cable modem... so overall, that was a complete waste of time.
Now, my downstream signal level, as reported by DocsDiag, is currently -4.3dBmV . As far as I'm concerned, this is *too low*. But how can you argue with a man who's job it is to test that?
The SNR is also a bit too low at 26.6 . Furthermore, I'm getting uncorrectable codewords at a rate of 100 a minute.
It's just a bit annoying that when the system upgrades are done, I'm going to have to ring NTL again and get another engineer out to try a new modem.
