Hi,

I have the Skybox F5, and had internet with Sky.
I have changed providers and have been without internet (till the 7 march arrgghh.

I bought a wifi dongle and linked the box to my phone by portable wifi hotspot. It was very laggy.

The solution for this is to connect by wifi hotspot.
Open an app on your phone (tunein radio is the best)
mute your phone and the picture will not freeze or lag at all.

Perfect

just thought I would share for any body using mobile internet on there skybox!

For reference I have a skybox f5 with latest firmware from the official site. My phone is a Galaxy S2, and the app is tunein radio which is free
