I would like to establish a wireless and wired network?

There really isn't much you have to do, hook your cable/dsl modem into the router, turn the router on, and it will be ready. You should be able to hook the wired computers into it with no problems whatsoever, and if you're using windows XP SP2 or newer the wireless will be no problem either. Of course you must have drivers installed for the wireless and wired adaptors, but that's umed. If you want to put security on the router, you will need to log into it with a web browser, preferably from one of the wired connections. This is in your manual, but most likely the address is a href="http://192.168.1.1" rel="nofollow"http://192.168.1.1/a and the user/pword will be in the manual, I can't remember what belkin uses off the top of my head, probably something like admin/admin. You should probably set a new pword for that, too. Somewhere there will be an option for wireless security, i prefer to use WEP, so after doing this, you will need to put the key on the computers that connect wirelessly too.
