I thought maybe it was somehow related to the EE content lock but I've allowed full access and the issue still occurs. All being well, it should come up normally and the admin password will be as per factory but with all the "better" Elisa firmware style features unlocked. To do that, you need to connect the router to the internet via Wi-Fi or Ethernet, configure the IP, gateway and DNS settings, then use the System > Software section in LuCI to install the luci-proto-qmi package. My local mast over 8 or so years went from 10, 15, 20, 20+10, 20+15, 20+20 MHz as it is now, and in the summer gained B7. I'm in the same boat, the speeds drop off due to high utilisation of Three's services in my area which is already sub par anyway.If you’re not quite sure if the Three 4G Hub is the right choice for you, there are a few alternative devices you can also use to get online using 4G or 5G mobile broadband. The new 4G Hub router (also known as the ZTE MF286D) supports download speeds of up to 600Mbps on 4G networks.

TFTP is like a method to send files and data - lots of routers have this outside of their main operating system to flash in a new or updated firmware thus making it possible to recover from a "bricked" situation.Plug in your ZTE board to power, being careful as its unsheilded and free from its plastic housing but dont power it on just yet. Now what you need to do is download a TFTP program (TFTP64 is my choice) and disable any wifi on your PC/laptop. Not sure this is applicable to the Three configuration as there are various internal configurations for the aerial connections, Gandi69 is looking at this at the moment.
