The X7 Aviation Tablet runs Android 13, and a few of Android's "helpful" network features get in the way of aviation use: they drop a Wi-Fi network that has no internet, which is exactly what an ADS-B receiver is. Here are the settings that fix the common complaints.

Wi-Fi keeps dropping or will not stay connected

1. Prefer the 2.4 GHz band. Settings › Network & internet › Internet, scroll to the bottom, Network preferences › Wi-Fi frequency band › 2.4 GHz.
2. In the same Network preferences screen, turn Turn on Wi-Fi automatically off.
3. Turn off the Network Monitor switch under Settings › Network & internet, if your X7 has it.

Does not reconnect to the ADS-B receiver on its own

Android keeps mobile data active and prefers it over a Wi-Fi network with no internet. Turning that off makes the tablet stay on the receiver:

1. Go to Settings › About tablet and tap Build number seven times. A message confirms developer mode is on.
2. Go back to Settings and search for Developer options.
3. Scroll down and turn off Mobile data always active.

The tablet now reconnects to the receiver automatically.

Will not join an iPhone hotspot

Some iPhone hotspots hand the X7 an address it cannot use. Giving the tablet a fixed address on the hotspot fixes it.

1. Connect another device (a laptop or a second phone) to the iPhone hotspot and note its network details: IP address, subnet mask, gateway and DNS.
2. On the X7, go to Settings › Network & internet › Wi-Fi, tap the gear next to the hotspot network, then Edit or Advanced options.
3. Change IP settings from DHCP to Static.
4. Enter the values from the other device, with two changes:
   • IP address: same network, but change the last number so it differs from the other device. If it shows 172.20.10.5, use 172.20.10.6.
   • Network prefix length replaces the subnet mask: 255.255.255.0 is 24; 255.255.255.240 is 28.
5. Use the same gateway and DNS as the other device. Save, then reconnect to the hotspot.

Also make sure the iPhone's hotspot has Maximize Compatibility turned on (Settings › Personal Hotspot), which enables the 2.4 GHz band.
