Both of the previous answers :-)
You need to first turn off the DHCP server (this is very important or
you will mess the net up for everyone in your hostel) and then connect
the uplink to one of the regular ports instead of the normal uplink
port. That way your WiFi router acts like a switch and just passes on
all information to the servers in CC instead of assigning IPs by
itself.
Please remember to turn off the DHCP - this can really mess things up
for everyone else otherwise. Of course, what this means is that now if
you want to configure your router you will need to manually assign an
address to your PC that is in the subnet of the router.
