Hello everyone,
I’m experiencing an issue with my Raspberry Pi 3 B+, which is configured as a Wi-Fi access point with the DHCP server enabled and Ethernet disabled. The Wi-Fi becomes unscannable after running for some time. This problem doesn’t occur on other Raspberry Pis with the same configuration, so I suspect there might be some uncontrollable factor involved, such as the power supply.
When this issue arises, performing a power cycle doesn’t resolve it. The system log continuously shows "wlan0: carrier lost" error each time the Pi powers up.
Interestingly, I found that replacing the following files and then restarting the Pi resolves the issue temporarily:
/etc/hostapd/hostapd.conf
/etc/network/interfaces
/etc/dhcp/dhcpd.conf
Unfortunately, I forgot to back up these files before replacing them, so I lost the chance to verify their contents. My question is: Could these files become corrupted or change during runtime? Has anyone else encountered a similar issue with a Raspberry Pi configured as an access point? Any insights or suggestions would be greatly appreciated.
Thank you!
