Verdict: If your Wi-Fi keeps dropping or Bluetooth headphones stutter after installing Android 17, the issue is typically caused by legacy MAC randomization conflicts or outdated Bluetooth AVRCP cache profiles. Resetting Network Settings and setting Private DNS to automatic resolves 90% of connectivity drops.
Software updates should improve connectivity, not break it. Yet across Reddit and OEM support forums, users updating to Android 17 report persistent Wi-Fi dropouts (especially on 5GHz/6GHz Wi-Fi 6E bands) and Bluetooth audio stuttering when connecting to car infotainment systems.
Follow this troubleshooting checklist to restore rock-solid wireless stability.
Fix 1: Reset Network & Bluetooth Settings
This is the most effective initial fix because it purges corrupted radio routing tables accumulated during the OS migration.
1. Open Settings > System > Reset Options (or General Management > Reset on Samsung).
2. Tap Reset Wi-Fi, Mobile & Bluetooth.
3. Confirm the reset. (Note: You will need to re-enter saved Wi-Fi passwords, but your personal files and photos remain 100% untouched).
4. Restart your smartphone immediately.
Fix 2: Switch to Device MAC on Home Wi-Fi
Android 17 implements aggressive MAC address rotation for privacy. However, older home routers can get confused by rotating virtual hardware addresses and drop the DHCP lease.
1. Open Settings > Network & Internet > Internet / Wi-Fi.
2. Tap the Gear icon next to your home network name.
3. Tap Privacy and change the setting from “Use randomized MAC” to “Use device MAC”.
Fix 3: Downgrade Bluetooth AVRCP in Developer Options
If your Bluetooth audio disconnects randomly when paired to your car or earbuds:
1. Enable Developer Options (go to Settings > About Phone and tap Build Number 7 times).
2. Open Developer Options and scroll down to the Networking section.
3. Tap Bluetooth AVRCP Version and switch it from AVRCP 1.6 down to AVRCP 1.4.
4. Toggle Airplane Mode on and off to refresh the Bluetooth stack.
Fix 4: Disable Battery Optimization for Bluetooth Services
Android 17’s aggressive background sleep manager sometimes puts the Bluetooth hardware daemon into deep sleep while streaming audio with the screen turned off.
– Go to Settings > Apps > Special App Access > Battery Optimization.
– Tap the menu at the top, select All Apps, find Bluetooth, and set it to Unrestricted.
