Alrighty folks, first entry.
I have recently switched firmwares on my Linksys WRT54GL from DD-WRT, which has, despite its bloatedness, always served me well, to the Tomato firmware.
The first thing you’ll notice is the entirely different Web-Interface. Everything is based heavily on AJAX, so the load on the firmware’s HTTP server is reduced. Additionally, configuring becomes a lot more “fluent”, as only the values that the Web-Interface presents you with, are being reloaded, instead of the entire page.
