@ alzhao: Thanks for your reply.

Where can I turn off the repeater manager? Are you talking of the menue INTERNET → Repeater → Repeater Options? After clicking on Repeater Options I get a box with the two options:

  1. Auto detect Captive Portal (OFF)
  2. Auto scan and re-connect (ON)

I switched “Auto scan and re-connect” from ON to OFF. Does that mean “turning off the repeater manager”? Is it enough to reboot or shall I power off and on the device?
