the passphrase is just an alpha version of your hex key... dont bother writing it down

also as discussed, use WPA if possible. (the belkin supports it, just make sure your laptop does)

MAC Filtering seems like a good idea in theory, but in practice its a pain in the arse... avoid (imho)

also turning off DHCP is not exactly a good security feature, to someone like myself that'd hold me up a whole... well... 10-15seconds? again, not worth the agro.

one thing tho,dont use 192.168.0.x as the subnet, it's a fookin broadcast address dunno why the manufacturers sship it as the default!. use 192.168.1.x just make sure the 3rd octet isn't a 0 or 255
