A beuatiful, little gigabit router. Runs great with OpenWrt and can do gigabit throughput with SQM.
I’ve used this for several years as my home router. I find sqm limits the throughput 10% but I disable it for the ingress anyway. Super reliable so far.
You’re supposed to set SQM lower than the WAN throughput. I think you’re right that by default it limits it by about 10%. There was some study over a decade ago on this that showed 20-25% limit is best for maximizing responsiveness under load. It’s not possible to effectively schedule packets if there’s no headroom.
I did go back and test and I don’t see the bandwidth limited around 750mbits. I upgraded openwrt since I originally setup QoS. Now I can get my full connection speed if I set the limit artificially high.
I have a few Pi 4 + UE300 routers in operation that work just as well but this is a nice alternative if you have a CM4 lying around.
Is there a 2.5 gigabit version?
NanoPI R5S.
I don’t think so, not by DFRobot at least.
Or if you have separated your devices into subnets/VLANs. Which becomes more important as your get more hardware that you don’t really trust.
Yep, you’re right. I’m watching my ISP upgrade their cable to docsis 4.0 which will alliw for 2g down 1g up. Instead of the garbage 1g down 40mbps up I have now. That upload speed is chaffing.

It there a reason you went for a CM4? When I priced it out it didn’t make sense

Got the module some years ago when there were massive shortages. I found a couple CM4s and bought them at the time.
