Hello, dispite all the other issues with the EA8500 (SMB Security flaw, non-functioning parental controls/network map/flawed FTP server, horrible guest-network implementation) another one has sprung up. It appears that the 2.4 Ghz band has some real issues maintaining connections with clients. Clients begin disconnecting and reconnecting constantly, with the only remedy to reset the WiFi signal on the router or reboot the client device (in my case I have three extenders 2 RE7000 & 1 RE9000 that are the only clients for the EA8500).
Can this please be looked into? Its quite annoying to have to reset the extenders every few days to make this issue go away...
This is the log pulled from one of the RE7000 (connected via cross-band back to the EA8500)
