for some reason, both my android devices, a tablet and a phone, refuse to connect to my AP, regardless of which channel Im on, auto or manual.  My wifes iPhone and our Roku3s appear to be unaffected.  I can reboot the androids, no help.  If I reboot the AP, or change its wireless channel, they start working again.  is there some method to debug to see what the error is?

when it happens ,the devices see the available saved BSSID, and when I click connect it tries then just goes right back to disconnected state.  no error on either device.

Delete the saved connection, reconnect with your password


If that doesn't work change to a new password

I had everything set to auto, except channel management, because my wifi printer wouldnt work otherwise.  Ive just now discovered that the issue with printer is it just cant do 40MHz, so Ive enabled everything manual just now, and manually set 20MHz, will see how it works now.  its a TP-Link MR3420 on openwrt

maybe this will just make my issue go away, was just very odd that it only affected android devices.
