Upgraded MWEB ADSL, how long until it takes affect?

[twinghosts]

I just recently upgraded my MWEB adsl connection from a 4mbps to a 20mbps after barely being able to do the simplest of tasks. How long does it take on average for the new speed to take affect?

If your line can handle 20mbps, it should take about an hour for the new speed to take effect. Depends when they actually make the switch, but once they do it goes quickly.
