PWRLine/cAP connection problems

Hi, i face some problems with wireless conections.

cAP AC - same situation with or without security (wpa2)

  • 2.4 band works without problems
  • 5 Ghz band do not allow some devices to connect
  • can connect some windows laptops and some android phones(older android 5 or 6 or 7)
  • can not connect one windows 10 laptop and some android phones (one android 7 and 8, 10)
  • windows laptop is reconnecting in a loop
  • android devices show (NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION)

PWRLine AP - only with security on (wpa2)

  • 2.4 Ghz band exact same problems like with 5Ghz cAP AC

The devices was succesfuly connected to another devices like hAP, tp-link routers, huawei routers

It is probably something with settings, but i could not find it.

Thank you in advance for any help
