As the title says the line drops for hours or days to unworkable speeds or goes downright offline. I tried to change cables and filters but nothing changed. I should mention the phone also does not work anymore. I have ADSL2+ and my modem gives me excellent downstream snr margin (22.3 db) and attenuation(13.5db). Upstream rate is not as affected as it goes from 900 to 700 kbps.
Do you think the problem comes from the provider or from my flat? In case you think it′s my flat- is it the router or the phone/internet cables in the walls?
