Hello and welcome to the forum.
It would appear, form your video, that your Dell (software) Wireless Connection Utility has taken over from and probably disabled the Windows (WLAN AutoConfig) Utility.
It would seem that the Dell Utility is identifying other Wireless Networks in your area satisfactorily and you shouldn't have any issues finding and connecting to available networks using this utility when traveling.
If you want to use the WLAN AutoConfig feature in Windows instead, you will likely need to disable the Dell Utility and enable the Windows utility.
Click the start orb and type
services.msc
and hit enter
I am not sure if the Dell Wireless Utility is produced as a result of a service that is running but try looking for it in the Services Console if it is there, double click it and set the startup type to disable and stop it. If it is not the product of a service then you may have to find the software package (not the drivers) that is evoking it and uninstall that.
Scroll down to WLAN AutoConfig, double click it and set the startup type to Automatic and start it by click the start button.
Personally if the Dell Wireless Utility is working reliably and dependably as it seems to be, I wouldn't worry about it and just continue using it.
Regards
Randy
