Best Home Wifi Solution

Hi all,

I'm looking for a router which I can connect multiple devices to (up to 10), which can support HD streaming and internet.. the thing is that i'm looking for 4G mobile data soltion rather than cable / fibre / ADSL.

I don't want to pay line rental anymore and I don't have any options for fibure to the home and if I weren't paying line rental, I'd be able to get much better speeds but sacrifice on some data allowance.

In times of old, I would have looked at small business cisco routers which have USB ports compatible with 4G dongles but I can't seem to find this info on any of the high spec night hawk routers.

Am I right in thinking that I'd probably need to purchase a 4G Gateway of sorts which i'd connect with ethernet cable into a router?

If anyone has any suggestions, I'm all ears :)

Thanks folks
