A beuatiful, little gigabit router. Runs great with OpenWrt and can do gigabit throughput with SQM.
Is there a 2.5 gigabit version?

I don't think so, not by DFRobot at least. That said, I think 2.5G is only useful for >1G internet connections. On the LAN side, the switch is what matters for LAN throughput.
Yep, you're right. I'm watching my ISP upgrade their cable to docsis 4.0 which will allow for 2g down 1g up. Instead of the garbage 1g down 40mbps up I have now. That upload speed is chaffing.
But I'm looking for a new toy like this because my current router is only 1g.
I'm watching my fiber provider going bankrupt a month before finally patching us online.
I have 3TB of data, I can't back that up with 40 Mbps and occasional 10 min outages!
It took me 3 weeks to backup my 2TB of data.
over which protocol and settings? idk if borg can use file parts of previous but cancelled/broken upload attempts
Borg resumes where failed backups left off so if you keep running it until it completes it'll dedupe what is already there and eventually finish leaving you with just incremental backups.
Lol dont complain to much. You could be like me were i only have 1 option and although they just now released fiber earlier this year, im not paying the price for it. I've been stuck on 200mbps down and 30mbps up for years now and I'm paying as much if not more than people a few towns over that get 1gb. Also my ISP has no plan that allows over that upload speed no matter what plan you pick.
I have 4mbps down, 3 up. But I only pay $10/mo.
$50/mo for 1gbps symmetrical :p
Unless you're running VLANs, in which case the inter VLAN is normally handled by the router. I also expose my home lab services over BGP so all my traffic hits the router then comes back to my lab services.
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.
NanoPI R5S.
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.
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.
What are you comparing it to?
