On LineageOS (and most Android-based systems), you can change the Wi-Fi hotspot name (SSID) using adb by modifying the appropriate settings in the Android configuration database. Here’s how you can do it:

Steps to Change Wi-Fi Hotspot Name via ADB

1. Connect to your device via ADB

Make sure USB debugging is enabled on your device and you are connected via ADB:

bash
Copy
adb shell

2. Check current hotspot settings

You can check the current hotspot name (SSID) with:

bash
Copy
settings get global wifi_softap_ssid

3. Set a new hotspot name

Use the following command to set a new SSID (replace MyNewHotspotName with your desired name):

bash
Copy
settings put global wifi_softap_ssid "MyNewHotspotName"

4. Restart the hotspot

For the changes to take effect, you may need to restart the hotspot:

bash
Copy
svc wifi disable
svc wifi enable

Or toggle the hotspot off and on from the settings menu.

Notes

• The hotspot password can be changed similarly with:

  bash
  Copy
  settings put global wifi_softap_password "MyNewPassword"
  

• Some LineageOS builds or custom ROMs may use slightly different settings keys. If the above doesn’t work, check for alternative keys like tether_ssid or similar.
• Always ensure you have a backup of your settings or know the default values in case something goes wrong.
