I have many nerdy friends who have been Linux users for ages. But most of them don’t know such a thing as Openwrt exists or have never bothered to give it a try. It’s a very fun piece of software to play with and can be extremely useful for routing traffic. Wondering why it isn’t more popular/widely used.
I used dd-wrt for a few years, but I realized I didn’t need it as my new router have the functionality I want. I also realized my router had much better throughput with the stock firmware.
