I bought a BT Voyager 2000 ADSL wireless modem/router. Simple to set up and use - 802.11b connectivity to my laptop anywhere in BEagle Towers (OK - I know that's hardly a challenge...). It also has an ethernet socket for connection to a normal desk PC.
But I don't think it works with AOL........ No problem for me as I use another ISP; AOL junk disks go straight into the bin!
