After recently moving house Iv'e discovered that Broadband at the address will be less than 2Mbps & there's no available Fibre either so have decided to go for Mobile 4G WIFI with Vodafone,
It arrived today and once set up the speeds I'm getting varies between 5-16Mbps, if I can get to to stay around 16 I'd be happy, so was thinking of purchasing another router that I can use the broadband SIM card in, and then get an external 4G antenna to mount on the roof in the hope it will maximise my chance of getting a stronger Wifi signal

Just need a push in the right direction for routers that allow external antennas and give off good Wifi and also outdoor 4G antennas.......
