I received this router in place of another router that I was having issues with. After a few months, my android and windows devices started losing connection. I reset the router, my modem, reformatted my phone and all of my PCs in the house... then I started getting a connection message with my 5G 1 band saying it isn't secure. Everything was set to auto, so it shouldn't of been saying that. I turn off the 5G 1 band and everything works exceptional (as of time of writing) things like this shouldn't happen...
