Rasp Pi b+ connectivity

I have just got OSMC on my pi but it cannot connect to the wifi (2.4GHz - same as the dongle). I can use a remote on my phone to control it but for some reason, I cannot get any add ons to appear in the get more section.

I have tried to reset the wifi settings in the hope of it connecting but no use…

Some help would really be appreciated as I am not a coding computer wizard but still wants to learn and knows a few things.

Thanks :slight_smile:
