I recently bought a Tenda W368R router, and I hated the current firmware! So I decided to find a open source Linux type of firmware. My router was not supported by DD-WRT ans a few others. But if my router is not supported, how do I choose firmware, similarities? Is there a sort of universal firmware? Which firmware should I get? Any suggestions?
In order to use 3rd party firmware, it has to support the chipset and other hardware inside your router. You can try google or the manufacturer's website to see which wireless chipset your router uses, then see what options support that chipset. The three big ones are DD-WRT, Tomato, and OpenWRT/Gargoyle.
