Any wireless modem router will do it and a PCMCIA card for the laptop. AOL don`t support wireless on Silver as you said but a simple post in the Network Forum when you`re ready to set up should get you all the correct settings.
click here for a combined deal or click here for an alernative using a USB wireless adapter instead of the card. I`ve set up a few of these and they work fine with AOL. The beaty about the USB wireless adapter is you can switch it easily to a PC as well whereas the PCMCIA card will only work in a laptop.
