I have watched 2 videos from OneMarcFifty. They have helped greatly in leading me to the questions that I was trying to ask but lacked the insight to frame correctly. https://www.youtube.com/watch?v=vVoZppb_FR0 and https://www.youtube.com/watch?v=kMgs2XFClaM
Each video describes a scenario
Cheap Wifi Mesh alternative with fast roaming. That is router/gateway + APs connected back to router via ethernet cable using 802.11r for fast handover between APs
DIY Wi-Fi Mesh with OpenWrt. That is router/gateway + APs connected back to router via a specific wifi channel. No cables. That uses 802.11s to enable the backhaul for the mesh
What I am asking about is the combination of the two. What happens if I build a variant of option 2 with one or more APs connected back to the router with a cable?
Also something that confuses me a bit is in the 2 videos 802.11r and 802.11s are mentioned but not explained in detail, so i might mix the 2 up
My situation is this. I have some cabling that can be used for wired backhaul. However it needs further preparation, so cannot be used immediately. My existing wireless mesh network has died. It worked well for the users in the house but was not based on OpenWrt. So, I want to upgrade to OpenWrt wireless mesh immediately
I will be using different hardware (Zyxel WSM20s throughout - one as a gateway router, the others as dumb APs). I will then gradually make the further upgrade of replacing the wireless back haul from one AP with an ethernet cable, then the next, etc.
eduperez said, "If you can wire them, forget about the mesh and do not look back." I assume that this is scenario 1? However, my sitation is that I need the mesh initially.
psherman then said, "......Are wired connections to all your (planned) APs available now? If not, obviously you'd use a wireless bakhaul for now and hopefully move to wired in the future, if that is an option."
The "If not" option is my situation - with the additional constraint of not being able to move all APs to wired back haul at the same time.
When I configure the backhaul interfaces to wired, does this automatically remove the 802.11s mesh functionality and revert to a situation where the AP(s) with backhaul are running 802.11r?
And, most importantly from my point of view, can an AP with wired backhaul co-exist with an AP with wireless backhaul when both are offering the same SSID and rapid switchng between APs.
If not, then I will have to ditch my plan for gradual transfer and instead work out how to do a "big bang".
