I have WiFi again

To all you bitches always be whining about there not being any wireless up in here....

There's wireless here now. Fully open, unencrypted and advertised ESSID "FitzPublic".

Note to self: (for when router inevitable dies and I'm back in this mess)
HyperWRT + firewall script of:
iptables -I FORWARD -s 192.168.1.1/24 -d 10.0.0.0/8 -j DROP
... seems to do the trick.
