The best model of the WRT54G line. I would snag them at thrift stores for cheap to use for silly utility functions. I always referred to that particular model as "The highly-coveted WRT54GL."

I used a pair to provide Internet access at a Customer's construction site back in 2010. Cell phone hotspot wasn't a thing for me yet. We took a pair of WRT54Gs, configured one as a WiFi client, the other as a bog-standard router/AP, connected the LAN from the client to the WAN on the router/AP, pur a directional antenna onto the "client", and pointed it down the road toward a big business who offered free WiFi for Customers. We leeched off that until the real Internet service got installed. (It was a restaurant and we ate there at least once so we were Customers, right? >smile<)
