Information source for cellular/wi-fi booster/repeater?

What is plug and play for a network technician, . Is not
Plug and play for everybody else
I'm a tech by trade, but not a network tech, and it even takes me a bit of work to set this stuff up
And once tried Wi-Fi sharing, virtual router etc..
It's usually slow and can be a real pita, it uses a resources of the computers cpu to route all the signals back and forth thru it's Wi-Fi chip
For any thing more than emergency use, get dedicated hardware/router
