Using router in a college lan

ok the router itself will have the 10.10x ip, does your college use mac locking to restrict access to the network? if so you will need to use mac spoofing on your router to pretend its the registered machine.

if you are going to be joining the local file sharing circuit you will need to set up virtual servers/port forwarding on your router to point to a particular machine, for this its best to use a static ip on the machine you want to share.

you can manually set whatever range of ip's you like, it doesnt really matter, just have to look in the lan / wifi settings to set this.

as long as all your machines use dhcp (automatic ip assignment) you wont need to worry about settings them up with the ip, just set whatever you want in the router lan settings and the router will do the rest.

id reckon you could set the router to use dhcp itself (will probably be a box saying get ip automatically) which will sort out most of the connection issues.

when you first registered for the college lan what did they ask for? did they want a 16digit mac code when you signed up for the service?

if so, then you need to really look deep into the router, basically load all the advanced settings pages looking for the mac spoofing thing, likely to be under wan settings / system settings.

you have to remember your machines wont have a normal 10.10x ip address, just let the router do its thing and sort you out itself.

once its working then you can start messing around with ip ranges etc.
