@AIC 

Hi again,

Thank you Solla-Topee for your answer! Unfortunately I have already done everything consistently with the advice in the FAQ. Again, I have entered both the MAC adress typed on the back of the extender as well as the MAC adress for the RE650 that shows on the status page of the router, in it´s white list. Everything works just fine with the extender and equipment connected through the extender until the MAC filter on the router is turned on again. On the status page of the extender both 2,4 and 5G connections are lost and of course also the connection to the internet.

Still searchin for a solution!

Best regards

Anders

@AIC  if you look at the forums, they posted a message that they are using

proxy for mac's which causes problems for those using mac filtering. While mac

filtering does nothing at all for security, when used with a strong password and 

WPA2 AES and or SHA256 authentication and algorithms, you have a secured

network and easy to manage client list. 

There is no solution to this as they seem to have gone to proxy for all newer devices.

What you can do - and it is a pain - is look in your ip list to see what is connected

and find your range extender. Look at the first three sets of numbers. If you look down

the connected list of devices you will see that anything connected to the extender has

the the first three sets set the same. The last three sets are for each device. The problem

is, those tell you nothing if you do not already know what each is. The only real solution

is to make a list of your devices, get the last three sets and put those in a list to glance at.
