You realize these automobile hotspots have the same security as household routers and you create a password ?Indeed. A concern. No need to roll around with it.
Pull the vehicle close to the house or in the garage. Have the vehicle connect to your home's WiFi, "check for updates", install. Exact same process you do with your phones, computers, etc (though they tend to do it automatically and in the background nowadays).but automotive rolling router.........how to upgrade for next gen wi-fi router?
