All you can really do is check the solder joints, move the device closer to your Access Point. If all else fails, replace the device.
### Weaker Wi-Fi signal after upgrade
In some cases the Wi-Fi signal strength (RSSI) drops significantly after upgrading to a newer version, specially when upgrading the Arduino core version. In such a case it is good to save the devicee configuration and run `reset 5` command which erases all flash and resets parameters to firmware defaults but keeps Wi-Fi settings. This also deletes Wi-Fi calibration data and after a restart Wi-Fi will recalibrate. After this is done you will need to configure your device back to its previous settings.
