I have recently moved into a new house and every time the phone rings or someone dials out on the phone this distrupts the adsl connection. It's so frustrating as I can be in the middle of work and suddenly no longer able to connect for however long my wife or daughter happen to be on the phone...
I have had an ADSL line with Telkom for many years now and it has done the job alright. I haven't been one to download a lot so speed / uncapped wasn't really necessary. I am not sure what my line speed is, but it's on the slow end, and I think I get about 100GB a month from my current package...
