I've come across an interesting issue.  I have a BE900 router set up with a RE655BE wifi7 extender via EasyMesh.  With Access Control (white list) on, If I try to use any client using  a 802.11be (wifi7) adapter, I am unable to connect to the BE900 on all frequencies (2.4,5,6 or the MLO network) but I can connect to the network on all frequencies thru the RE655BE extender only.  If I turn off Access Control, I have no problems connecting to either router or extender.  Non wifi7 adapters have no problem with the white list on, either thru the BE900 or the RE655BE. 

Is there something I'm missing?
