Use whitelist as security for AP
My tplink AC 1750 c7 archer, works well in AP mode. I wonder how I can secure the AP. It is only used for software updates of my TeslaY. I have created a guest account and have chosen 5Ghz, because of less spatial range. I also want to apply a whitelist in guest mode with only the Mac address of the car as only Wifi-user. But that Mac address is not accepted. I have filled in the data 5 times with lower and upper case letters, but no result. I checked this adddress in the car and on the central modem.
Is it possible that I first have to log in with the car and fill in the whitelist from there?
thanks in advance for a problable solution
