I am using an old netbook running lxle to bridge the hotel like wifi in my in-laws retirement home to create (with a plugged in netgear traveling router) a private network so they can use their Amazon echo and watch netflix.
My problem is that after a day or two the netbook switches on its own from the hotel wifi to the private network it is creating (effectively talking to itself). I have no idea how it can be changing on its own and it has been doing this for months. Every day or two I need to link it back to the original network. I would appreciate any advice.
you can right click on the network manager find the wifi it's connecting to that you don't want it to and uncheck automatically connect to this service
