I have dsl broadband, but a friend who cannot obtain this, swears by a program called Tweakmaster by Rosecity software : http://www.rosecitysoftware.com/tweakmaster/
It might help.
In Spain modem internet connection is difficult. Normally the two indicator screens on the taskbar are off. Connecting is difficult because of the famous 678 errors(TELEFONICA say "the lines are saturated)
When they're on and I try to open any link they normally go dead. Send and receive email is poblematic. Sometimes we(many people here have the same problem) have to want five or more minutes to open a page.
I've tried "mindsoft internet optimizer", "webroot's accelerate", "speedconnect start", "bysort stayalive pro" without real success. Is there anybody out there with a solution to this frustrating problem?
