Erasing Time Capsule

Hi all,

My old Macbook recently went to computer heaven, i had time capsule storing back ups for approx 3 years of this time, my new macbook is trying to backup but the space is not available, (17.2gb of 998 available). I do not need any of the old mac book backups as i had the files i needed from the old one stored on an hard drive beforehand. My local Mac store has also setup the time machine as an internet network, which is how i access the internet.

What i need to know is 2.1 things,

1- Can i erase the time capsule to start from scratch? if yes, how do i do this (in basic terms & easy instructions!)

2- if i erase the time capsule will this delete the internet network that was setup?

2.1 if yes how do i reset this up (i was not there when the mac store set it up)

thanks in advance 🙂
