Meh. I use an old MN-520 PCMCIA card, and I picked up a Linksys WRT54G on ebay for $5. Yeah I use WEP with a 128 bit key. I turned on mac filtering and turned off broadcasting so only my Amiga can connect and I only turn on the router when I use my Amiga... about an hour or two once or twice a week.
Sure someone could wait around fo the hour that my router is on, sniff out a network that isn't broadcasting, spoof my mac, and hack my wifi, but the likelihood of that happening is pretty small unless they live next door, pointing a yagi at me, and waiting for me to power it up a network they don't know exists. I live in a rural area so that is very unlikely.
It was cheaper than buying a new card for $100 that supports AES, and finding another B/G router that is compatible with the updated yet outdated card.
One could also bump key your front door and walk right into your house and take anything they want. It's even easier than hacking wifi.
