I've installed a wired/wirless mix recently and it now works fine. Initially I had mind-boggling set-up problems but they've now been resolved.
My PC (the main one) is hard-wired to a D-Link wireless router. The PC belonging to She-Who-Must-Be-Obeyed is fitted with a D-Link wireless card, as is my laptop. Top tip (learned the hard way!) - before placing your laptop in its carrying case, remove the wireless and any other cards that stick out the side. If you don't, it's liable to get mangled if the case gets knocked...
And no, I haven't heard much good about AOL either - at least 3 friends have dumped them and gone BT.
