Broadband problems

Hi,
Are there any problems any of you have experienced with broadband when setting it up and installing it. I just ask because i've had enough of re-formatting the hard drive because i have corrupted the data. Any things i should watch out for or could avoid so as not to cause problems or is it really as simple as companies make it sound.

I have BT broadband and i have re-installed it many times, it is very easy not like setting up the old 56k, which took much longer, you shouldn't have any problems. :)

cheers going to get broadband on staurday on freeserve 512k.. fingers crossed!
