Sorry, I've had my router ages and have no idea how to find hardware version or any other details.

Tonight my naught rabbit chewed the power.cable so I need a new one urgently.

Need to buy one preferably from Amazon as I'll get it quicker.  

How do I find out what the hardware version is and the other thing it asked when I signed up?

All I can tell you is it has sim card slot, is 5g ready, my aim is 4g as we don't have 5g yet.  It's also 3g compatible. 

 What do I need to type in Amazon search to get into show the power cables instead of the routers?
