Setting up a Dynamic Repeater

If this applies to you:

You don’t want to pay for internet
The linksys gods live around you
Unfortunately, signals aren’t strong or are intermittent
Never sure which network is up and working properly
Don’t mind bricking a router

You can set up a dynamic repeater. Essentially, have your router scan networks to see what’s up and running and has the best signal, and rebroadcast it as your own private network.

How? DD-WRT

I did brick a really cheap crappy router trying this, but it was more for kicks. Make sure you have enough flash memory. Also, it might be worthwhile to check this.
