Now second thing you have to do is that Goto Your browser and enter
192.168.1.1
(note:your router damain may be different to know just type cmd in Run menyu and than type "tracert google.com" the first ip on No 1 shown will be your router's pages.)
now enter it in you browser find somewhere connect to internet There will be a button "disconenct" press it (if you are downloading a file wait before it completes otherwise it will be broken) Now connect using connection you just made you will only have to wait he regular time
Reason:each time you disconnect and connect again your IP is changed and Rapidshare cannot recognise you thats why it give you only regular time limit that is maximum 180 seconds
