#22239: WLAN is dropping some SSIDs
-----------------------------+------------------------
 Reporter:  kraut            |      Owner:  developers
     Type:  defect           |     Status:  new
 Priority:  normal           |  Milestone:
Component:  packages         |    Version:  Trunk
 Keywords:  wifi ssid trunk  |
-----------------------------+------------------------
 I configured 3 SSIDs on 2,4GHz:

 - lanlegacy with wpa2-psk
 - lan with wpa2-eap
 - languest with wpa2-psk

 In my setup i configured three TP-Link Archer C7 V2 (running trunk version
 r49166) the same way. After some time (4 hours) after reloading wifi, the
 device is dropping the ssid lan and languest, lanlegacy is still working.
 After using the command 'wifi', everything is fine for a while. In logread
 i see this:

 {{{

 This is the wireless config, which is exactly the same on all three
 devices, except the nasid:
