I have a SBS network, with an ADSL router connected for Broadband access.
One morning I notice internet was sluggish, timing out here and there, and generally a pain to navigate. After checking the ADSL router I saw the below picture (those errors are over a few hours period, over night)
The downstream SNR so very low, and flickers between 4 and 10, I have never had a problem previously on this line, and I havent changed any hardware at all
The broadband provider is AOL UK.
The line/exchange is owned and run by BT.
Tried changing usually settings MTU, PPPoA etc. Also tried changing filter. All did nothing.
My question is what has caused this, and is it AOL UKs problem? BTs problem?
