What To Do With Old 802.11b Equipment?

CyberSlugGump writes "I am trying to declutter, and I have come across my cheap, off-brand, consumer-grade 802.11b wireless routers, PCMCIA cards, and USB adapters. The routers would still be good as 4-port 100Mb switches, and the other devices have at least 32-bit Windows XP drivers available. However, lack of security beyond WEP and the age of the equipment makes me wonder if it is worth any time putting it to use."
