Vlan and wifi on WRT3200ACM

I cannot make wifi work and then set vlans.

vlan4 (lan)
vlan5 (guest)
vlan6 (iot)

I have done a lot of testing and never got it to work. ( do not have a config to post has had to go back)

Does any have a config that vlan and wifi work on WRT3200ASM that can send me?

I thinking of going back to stock as yes limited but does work not like wifi on drops all time.
Will wifi dropouts ever be fixed on WRT3200ASM?

I'm sure you've seen Users needed to test Wi-Fi stability on Linksys WRT3200ACM & WRT32X on OpenWrt 21.02, 19.07 still seems to be the "best" release for these devices.

You do not need VLANs to create wifi-only networks.

I could share my configs here, but my router is has lots of configurations that cater to my specific needs. I think it will be more productive to post you specific needs here, and work from there.

Starting basic but want to split it up more later.
