Connect to router via enet cable then Open a command prompt and type ipconfig /all the default gateway is your router ip. Type this into a web browser when asked for a username and password try the usual suspect ie admin and admin, admin and password, user and password etc you will then get into the config of the router. There may well be an easy set up route in there where you add your username and password (the same as is on the pc) it should all be obvious. By rights the router would have set itself up when plugged into phone line so all you need to do is add details, Then there will be a wireless tab click that and enable wireless then click security and select wpa passkey and input a memorable password. That shoudl be the router done. Now with the wireless adapter install that on whatever machine following the instructions when you get to scan for wireless it should find your router and just conenct and add the password.
Tip change default username and passoword of the router set up pages
