The United States FCC recently announced a ban on new consumer-grade routers produced outside of the US. This does not affect existing devices that were already authorized, and there is a carve-out for manufacturers to apply for a conditional approval. It’s difficult to say what the medium or longterm effects of the ban will be.
This got me thinking about what could be used as a makeshift router in a pinch. As it so happens, any computer that can run Linux and has networking interfaces can function as a router. This blog post by Noah Baily documents the process using various old computers and components as custom routers over the years.
These makeshift routers are not going to win any bandwidth speed races, but they’re perfectly capable of routing traffic for IoT devices or basic browsing. They’re also useful for capturing traffic to analyze or sharing internet access from WiFi to Ethernet or vice-versa.
This guide documents the setup process and capabilities of using a Raspberry Pi as a router. It does not require a particularly powerful computer, even the older Pi 3 B+ that lots of us have tucked away in an old parts bin works fine for this.

Didn’t read this particular article, but using a pi as a router works rather well. I’ve been using one as my main router for years now, with openwrt. You get a CPU fast enough to handle QoS without issues, more than enough power to run a few additional things if you want to (wireguard, AdBlock, …). Only thing is : the wifi is trash. Doesn’t matter for me (I just use the integrated wifi for a guest network, main network have dedicated APs)
Just fyi the older pis 3 and down have a somewhat slow ethernet connection if your going that route.
if your going that route.
I see what you did there.
