its very simple becuase the psp can automacticly finds it ip address and other infomation from an access point, some access points can have a password, this is unfortunate but also very good for internet security.
the psp will automactily know when to type something in. a new window will pop up with like the keys 1,2,3,4,5,6,7,8,9,0 just like a mobilephone (cellphone for the americans ) but some keys are designed like it
wow thats pretty cool but it seems pointless coz where there is a port router there is a computer normally.
its very simple to get a router and fix it up all together, if your computer does not have wireless system i bought this: works fine with any computer. and allows me to get any computer in my house on the network and shaare files using limewire (for its real perpose)
of the psp's special web site (only available on the psp) you can download content such as music and videos stright on the memory stick !
