That sucks, but you can setup an anon middle box in that case. An old laptop works well as an anon middle box without needing to buy extra hardware (other than a crossover cable, perhaps), because it already has two NICs. Just remember to route the connection from your Workstation into the ethernet port of the laptop, and use the wireless card to connect to your router, not the other way around. Also, you should use a desktop computer for the Workstation, or physically remove the wireless card from a laptop and connect to the anon middle box via ethernet, so an attacker who gains control of your Workstation can't connect to your neighbor's unprotected wifi and get their IP address. If we're talking about LE, and they know that IP belongs to your neighbors, they can knock on a few doors and find you pretty quickly.
