Well video calls and games never worked.
Having those few nodes, I think 802.11s routing is sufficient if you don't have to use VLAN either.
Video calls and games over a mesh are always going to be problematic, since it means retransmitting packets multiple times over the air it compounds packet loss and latency jitter issues.
Is there anyway I can improve the quality?
The best way to get high quality interactive communications is to use wired devices.
@bluewavenet already mentioned to make sure you have SQM installed on the router and configured.
But you say:
So that means SQM by itself won't solve your problems, because the issue isn't just from high traffic it's from radio environment. At this point in time your best bet is:
- wire the access points to the gateway node
- If you can't wire it in, change channels. I like Wifi Analyzer to explore the wifi environment and choose channels
It would be useful to see a dslreports speed test result link for a speed test run on "device 1" and a speed test run on "device 2"

Hey, really great to have experience from people having a mesh network with OpenWRT.
I don't agree with people saying that video calls or games over a mesh will always be problematic!
Because I'm trying to replace my previous mesh set-up Orbi rbk23 (1 * RBR20 + 2 * RBS20)where the end computers are currently used for game and video calls, and I never had any problem ! In fact it was really great and with some test (proof.ovh.net) I easily go to the 400mbp/s (computer connected on the mesh node RBS20 with RJ 45, estimated distance between the RBR20 and RBS20 20 meters separate by a floor and at the extremity from each other in the house). Never had any issues with the call, neither with game (e.g., csgo).
But with my new setup (see related post : Home set-up with OpenWrt and Ubiquiti), which is similar to the previous one in terms of distance and use case, I tend to freeze if i'm having huge bandwith.
- So maybe it's related with my configuration (currently have a post concerning some issues: Mesh with Batman and DHCP per vlan, only one VLAN get an ip).
- Or a different protocol that the one used by Orbi mesh products ?
- Or the hardware (but I don't think so...)
- I'd not say that OpenWRT is the cause, I found some post on reddit arguing that Orbi products are based on OpenWRT ( https://www.reddit.com/r/openwrt/comments/l0v9gw/does_orbi_netgear_support_openwrt/ and Netgear Orbi RBR50 build?)
From a first test with the new set-up, I was able to play csgo, but If I'm doing a speed up test, it crash the mesh network after few seconds. Still, I've approx 200mbps in average during the first seconds.
