Hi, I'm having issues getting IPV6 working on my router. I'm using LTE and I know my provider (EE) supports IPV6.

When I change the setting on the router to use IPV4 and IPV6 I notice that the router does not fetch and IPV4 address, only an IPV6 address.

So that's my first problem.

Secondly, and I think this will be cause by the first problem, all of my devices work fine on the network but some apps like steam aren't working. 
I'm assuming this is a lack of dual-stacking.

Basically, how do I get my router to pull an IPV4 and not just an IPV6.
