I know this is an old thread but I actually have 2 such ATT Nighthawk hotspots and a MX64Both have Ethernet jacks and I can turn off the Wi-Fi so any user is subject to Meraki content filtering and protection.Can there be 3 feeds?

At least one large company I worked at dictated that NO unsupported devices could be connected to their network. Why permit known vulnerabilities?It is a CFATS special!

THIS is why security is so important in the process/manufacturing/automation domains. Weak devices require strong protection, preferably, isolation

Dunno why but the save button refused to show until I simply used precisely the sequence you listed. Arrrrgggghhh!
