Just flashed the latest firmware. Did a reset to default settings, reboot, upload firmware, reset to defaults again, restart, apply all appropriate settings.

For some reason the R7000p defaults to 40 MHz on the 2.4GHz spectrum (I only need 20MHz width), and despite what I put in defaults to only 20 MHz on the 5GHz specturm. This has been the case with many different firmwares I’m running (currently running the latest). Maybe the settings aren’t applying appropriately, i’m not sure.

The only way I see this is with Wi-Fi Explorer pro, showing the R7000p with the inappropriate channel widths (all other routers are behaving).

Any ideas?

Define "latest firmware".

Are "all other behaving routers" Broadcom?

if you want a good working router without stupid restriction made by the chipset vendor. just dont buy broadcom based products. its nothing i can fix. the channel restrictions are hard coded in and baked into the chipset.

sounds like you have the channel set to auto

you need to set a channel for each

Post a 768 pixels wide picture of your Status>wireless Tab for each of the radio's. That will help guide us, and you, to determine what the router is actually "thinking" it's broadcasting and then you can compare it against a client app that shows what it "thinks" it's receiving.

I personally like to use inSSIDer to evaluate my settings vs what clients see. It should still have a "free" option. As for iOS and Android, there are a ton of apps too as you noted.
