I tried AiMesh for awhile in various combinations of routers (AC68, AC3100). I use all wired backhaul on a 1Gb switched network.
There were things I liked and things I didn't with AiMesh. I like the fact I could easily see which clients were connected to which nodes and I had a "dashboard" in the main router. I liked being able to do updates through a single router. I didn't like the loss of control of channel assignments. I didn't like the loss of access to individual routers' GUI. The only way I found to reboot an individual node was SSH or a physical reset. I also didn't like that my perfectly good AC66 routers couldn't "play" in AiMesh (I still used them in AP mode with the mesh). I use these older devices out in the detached garage and other places to cover outdoor access.
I just reverted to AP mode.
My house is tall and long and narrow and I'm fortunate to have pretty much full unfettered access to all spectrum of both the 2.4GHz and 5GHz, bands. I also cover most of 2 acres with this setup. I'm running an AC3100 as the main router and 2 x AC3100 in AP mode in the house (upstairs center and each end down), 1 x AC68 in AP mode the main garage, 1 x AC66 in AP mode in Bus Garage, and 1 x AC66 in AP mode on covered patio. I also have an AC68 setup for AP mode that I can plug in outside on a post in the "back 40" for larger gatherings. Yup, the guy that built the house wired it well
Yes, it's overkill but I'm retired and have the time and equipment kicking around
I've included a snapshot of what the 5Hz looks like where I currently sit. It's a near perfect evening for WiFi here in Texas
MY recommendations would be to begin basic
Leave the radio channel selection "Auto", set the same SSID/passcode on all routers/radios, and turn on/off all the same features people list in numerous posts (beamforming, roaming assistant, channel widths, ...). As you gain confidence and knowledge you can begin to use tools like "WiFi Analyzer" to pick channels if overlap becomes an issue and try different features.
FOR ME, AP mode allows me more granular control, isn't really any more complicated to set up, and allows me to continue to get use from older hardware. OH, it also allows me to use Merlin firmware
PS - I keep one saved config/profile for each hardware type that I have so I can readily reset and reload should the need arise. I've included my base wireless screenshots from a RT-AC3100 below.
I have a question getting back to the original article that this thread is based on. In the conclusion section Jim states:
My question is on the "configuring them yourself" part above. If you wanted to skip AiMesh and configure two routers (say a AC86U as the router and a AC1900P as the WAP) how would you do that? Besides setting the SSIDs to be all the same is there anything else one would do? I have seen this touched on many times in these forums but I can't recall ever seeing a definitive statement on how to set this up.
