In the middle of january, my household's ADSL line was going on and off with us only being able to get a connection throughout small time periods in the day. This lasted almost a month. The Wifi singnal had finally come back in the middle of February. However, as soon as the wifi came back, we noticed a very big problem, we were only getting 40% the speed of what we pay for. Not wanting to downgrade, can someone please help or explain as to how this is possible, and can be resolved?
