Still not able to use this app to control my wifi router (Nighthawk r6400v2). When it asks to login to the router, I keep getting "logon timed out, please try again. If this issue persists, try rebooting your device". I've rebooted it multiple times to no avail. Even unplugging it for almost an hour. Been like this since last firmware update. I can logon via web browser and firmware is up to date. Only other option would be to do full reset on router.
