Hello Marek,

I suppose you are not planning to do any kinds of advanced config using several VLANs and multiple SSIDs so let's just make your configuration simple and working.

In short, you need to remove all references to VLAN 1 and to any subinterfaces possibly related to the VLAN 1. This means in particular (follow these steps in sequence):

  • Remove the Dot11Radio0.1 subinterface entirely
  • In the Dot11Radio0 section, remove the encryption vlan 1 mode ciphers tkip command
  • In the dot11 ssid ciscowifi section, remove the vlan 1 command
  • After performing these steps, make sure that the ssid ciscowifi and encryption mode commands are still present in the Dot11Radio0 configuration, and if not, reenter them.

Best regards,
Peter
