This is pretty cool!
My friend had a WRT54G V3 that was acting up. It came into my possession for tinkering. After failure with OpenWRT and wifi, I tried Tomato. There were a few tricky bits, like TFTPing the firmware to the router required the use of a switch cuz my laptop didn’t enable the network fast enough, and holding the reset button while powering up the router.
The real-time traffic graphing is pretty badass! The wireless site survey and wireless bridge is pretty sweet too!
