Possible cause of dropouts & increased SNR

[adamb]

I have been recently having issues with my connection. I was quite happily on a solid 3dB profile with a sync speed of around 1750 kbit/s. I did start to notice that the higher frequencies on my ADSL2+ started to drop out which increased CRC errors etc. I would just reboot the router thinking that it was maybe a line problem. (I was recently getting really bad crosstalk and could hear two way conversations quite clearly! I did report this to IDnet, a few days later a BT man turned up and sorted the problem out but almost severed the whole line with his ladder!).

My profile is now on 9.2dB and I have a sync speed of 13629 kbit/s.

I think I may have found the problem...

I (naughtily) set my wireless router to the USA region which has greater TX power and gives more wireless range than the European profile. My router is sat very close to my phone master socket because I use a very short modem cable to minimise loss and interference. I have since switched back to the Europe setting (less wireless TX power) and I have not had any more dropped connections or high frequency dropouts.

This is just a guess but it's a big coincidence. Sods law says that as soon I post this the same thing will happen again   I shall reply to the thread if it does but so far, so good.

My profile just dropped down to 6dB and the sync has increased so the connection seems to be restoring itself to its former glory

Damn, scratch that. The problem has returned. I have tried 5 different microfilters and I am still getting sudden random drops in SNR and tons of CRC errors. Back to the drawing board
