After moving to my new place, I found that the stability of my ADSL has gone through the roof. I'm still connected on the same exchange but all the wiring in the house is brand sparking new.
At my parents place, I was getting disconnected every couple days and of course when it rained.
At the moment my modem is reporting 19 days up time.
How many days has your ADSL been up for?
Edit: I'm on ADSL2+ about 4.5 Km from the exchange. At my parents place I have just normal ADSL 1. Last time I checked that modem was reporting about 57 days up time.
