I'm not sure what is my problem but it shows that the Unifi Air is connected but sometimes my Internet is stuck on loading or an error in detecting Internet will come up. The Unifi Air is placed next to my computer and transmitting wirelessly.

Furthermore, since I have other devices (iPhones, tablets and laptops) some will be connecting fine while others are stuck with the error messages.

No idea what is wrong. Speedwise it's waaay better than Streamyx but connectivity wise it's poor.
