rpi4 VS openwrt-rockchip

I've never tried using mine WITH the starlink router & ethernet adapter as I have clipped the cable and used a POE injector, but there shouldn't be anything preventing it from working as far as I know. Depending on what you mean by 'use with' and assuming you mean 'use the Pi 4 as THE router, have you tried this firmware/OS?

Currently my setup is a Cable modem -> Raspberry Pi 4 -> Wifi router. I am running a recent openwrt rc build on the pi (using https://github.com/wulfy23/rpi4/, shoutout to wulfy for maintaining this!).

Given wulfy's latest message on his readme that builds are on life support, it might not be a great idea to continue pushing his builds.

I'm using a Pi4 as OpenWRT router without problems. But I don't use the built in wifi (I use a mikrotik AP). I use this image: https://github.com/wulfy23/rpi4

Here is the link to his github: https://github.com/wulfy23/rpi4

*github *forum topic or just go for official build instead of community build

Now here's the kicker. Looks like vanilla openwrt only clocks the chip to ~1Ghz or thereabouts. I've installed this modified fork https://github.com/quintus-lab/openwrt-rockchip

Use this build instead: https://github.com/quintus-lab/openwrt-rockchip

I recommend installing this build of openwrt

Anyways, please, don't stick with the official openwrt build, nor the friendlywrt proprietary build. Use this firmware instead which has specific performance adjustments and patches.

This might help you

Thanks for your answer. I am looking at the nanopi rs4 board and it seems to have support for wireguard https://github.com/quintus-lab/OpenWRT-R2S-R4S
