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.
the option i suggested is also a single device.
most commercial routers can run openwrt. you dont need a specialized device.
I still need a cable modem. And as far as I know, none of the ones that can be used with my provider support any other OS.
thats something you would have to discuss with your cable company, and they would probably tell you to removed right off.
i wouldnt recommend you to mess with that anyway if you dont want to have a variety of problems.
