How do I keep my wifi on a specific wifi (Lumia 820)?

[Windows Central Question]

I have a Lumia 820 and I have a problem with the Wifi Settings.

When I'm at home my mobile connects to Wifi-with-FON instead of my Home Hub (BT Home Hub 4) Why is this? I manually go into Wifi Settings and change the setting to my home hub, but 30 mins later if I want to use Wifi again it has reverted back to BTWifi - with-FON!! This is really annoying. How do I stop this?

Is Wifi-with-Fon a hotspot if so in settings you can disable that it connects to it. SETTINGS < WIFI < manage < automatically connext to Wifi hotspots .....
Here you also can delete know networks so you can also delete it if you see it.
If the FON has a stronger signal than your home-hub than this may be the reason that it connects to FON.
