Technical Assessment of Lenovo Tab M10 Plus Wi-Fi Disconnections

The technical assessment for the Lenovo Tab M10 Plus indicates a high probability (approximately 80%) of software-related causes behind Wi-Fi disconnections. Often, the tablet fails authentication (55%) due to missing or incorrect CA certificates (a common issue on WPA Enterprise networks) or disconnects due to the random MAC function (25%). Typical signs of this scenario are "Authentication error" or "Obtaining IP address" messages followed by an immediate connection drop.

Quick Wi-Fi Checks Checklist (Zero Cost)

To attempt to resolve Wi-Fi disconnections on your Lenovo Tab M10 Plus, follow these steps:

1. Verify and Install Eduroam Profile:
   • If you are using a WPA Enterprise network (e.g., eduroam), ensure you have installed the correct profile via the geteduroam or eduroam CAT app.
2. Disable Random MAC:
   • Go to your tablet's Wi-Fi settings.
   • Select the Wi-Fi network you are connecting to.
   • Look for the "Privacy" or "MAC type" option.
   • Select "Use device MAC" (or "Phone MAC") instead of "Random MAC".
3. Check Power Management Settings:
   • Less likely (15%) is an overly aggressive power management setting that disables the network card. Ensure that power-saving settings are not disabling the Wi-Fi card in the background. Consult your device's manual for specific battery and network management options.

Only in 5% of cases is hardware damage to the internal antenna found, characterized by an extremely weak signal even when close to the router.

Replacing components such as the Lenovo Tab M10 Plus Wi-Fi Antenna and using specific equipment, such as a Professional tablet opening tool kit or a Professional digital multimeter, require the intervention of a specialized technician.

Operational Decision: If software configurations do not resolve the issue, it is advisable to consult a qualified technician for a hardware check. Physical component replacement is recommended only if the estimated repair cost does not exceed the tablet's residual value.
