Wireless Range Extender
I got the change to visit Fry's yesterday and came home with a WRE54G, which is a Wireless Range Extender. I had always problems with my laptop connecting to my wireless access point located in the other corner of the house. The root cause is that the laptop is crap - others can easily connect. The solution is a Wireless Range Extender, which picks up a given 802.11B/G signal and repeats it. No cable needed, it is all over the air, just plug into power. It works nicely - I have "excellent" signal strength now. The downsides: the device does not do "N" and it took me two hours to configure because I forgot that I have MAC filtering enabled in my router.
