Eric uses the Hotspot mode on his Note 8, but not every device can see the Wi-Fi connection. Leo says that there are two frequencies, 2.4GHz and 5GHz. The phone does both. So he should check on that. He should also check on the encryption he's using. His devices should at least see it, though. It sounds like SSID hiding may be turned on in the phone's hotspot settings. If it is, then he should uncheck it. He may want to take it into his carrier store.
Dan is going to be in a hotel for a few weeks while his apartment complex is being renovated.How can he be secure with Wifi? Leo says that a portable travel router like the Tiny Hardware Firewall will keep you good and protected. But if you turn your phone into a wifi hotspot, you're just as secure because it's encrypted, especially on GoogleFi.
