I originally wrote this up for MAKE magazine, but here's a quick and dirty version. If I find my original artical, I'll add it here.

Concept

Make a low cost, hardened AP that'll withstand a firehose directed at it.

Players

Linksys WRT54GS $40
FAB Corp NEMA 6 housing $20
walmart cutting board $1
Female N firewall adapter
N to linksys antenna adapter
External N 802.11b/g antenna

Quick and dirty


Dissasemble the WRT.

Remove the antenna connectors with a dremel tool from the wrt54gs.

Make a Power over Ethernet adapter. -more notes on it here.

Mount the board to a cut down cutting board as a simple insulator/mounting block.
Use the wired connector to connect to the N firewall connector.
Add a sealing connector to the housing
Run cat5 into it, connect the PoE spliiter and close everything up.

Mount it to the house.
