Trying to intall Arlo Q and page asks for network SSID and password. However my system requires a username and password.

You connect a Q in the same manner as a laptop or phone, using the SSID and passphrase. At no point is a username and password ever required. Maybe you're referring to logging into the router for configuration as opposed to just connecting a WiFi device?

I think he's saying that his WLAN authentication requires a username and password. Usually this is seen on business/corporate wireless systems. I would guess the only option would be for him to whitelist the camera's MAC to not require the user/pass login.
