I need to actually sit down and write this up, but here is what happened:

1) Disabled the Actiontec M142(something)'s wireless signal
2) Put my old WRT54GSv2 on the network
3) Installed DD-WRT v23 sp2 on the WRT54GSv2
4) Boosted the signal
5) Attached two 125% sized Windsurfer Parabolic Reflectors to the WRT54GSv2 (Sarah helped me to print/make them)
6) Replaced Sarah's WUSB54GS with a 6dbi gain antenna attached to her internal ZyXel 302 (the signal is more consistent, now)

We're trying to save money. As such, we've been evaluating where we are basically just throwing it away. Given that one of the main reasons people cite for divorce (outside of that always fun 'irreconcilable differences') is money, I think it's very wise and healthy that Sarah and I are both open and honest about our financial state, both as individuals and as a whole.
