So since I have started using this router I have had this issue.  I need to reboot it each time this happens to resolve it.  Basically I am only using 5GHZ band and every so often wireless clients are suddenly unable to connect to the network and it will sometimes report that the password is incorrect when it is not.  When I reboot the router the issue resolves itself, this occurs easily once a week.  I would love to fix this problem and I see some others in the community have had similar issues.

Thank you.
