I am extremely cautious with all networks. For instance, when my laptop, which is my primary web interface, is not actively in use on the web I disable the network interface. I never leave the laptop powered up at night, or whenever it is not in use. I have two large desktop machines used for other purposes. They may connect to the network for 1-2 minutes per day. They are also powered down when not in use. I have an Android phone but I use it only for telephone calls and pictures. I do not do anything financial on the phone. When off cruising I bring along a second laptop that has nothing of personal value on it for connecting to the web. I have no "accounts" with google or any other vendor. I stubbornly refuse to allow any software to update itself automatically. I don't download so-called "apps", many of which are trojan horses.
Frankly, I'm terrified of the danger these networks pose but realize that there is some business which must be conducted on the web. I just minimize those actions and the time required.
As an aside, I recently purchased a new printer. All I wanted was a simple USB connection. Couldn't find one. They were all "network" printers. Terrible mistake. The damned thing sits there and talks to someone, somewhere whenever it is turned on. Often it is simply too busy updating itself, communicating with the mothership, or snooping my home network to do the damned printing job I need!!!!
I do the best I can......
