*****please help******linux newb******** no background*****

Hi everyone. So I've installed Kali linux. I'm in the UK and for some reason none of my devices allow me to browse to kali.org unless I come off my wifi. so in the web browser i get 'The connection has timed out' message
and in terminal when trying to install ufw again it times out. does anyone know how to get around this. I suspect its something to do with my ISP which is SKY and i have a sky hub.

Any help much appreaciated
