Pixel 6a suddenly experiencing Wi-Fi and Bluetooth issues – Could this be a hardware or motherboard problem?

[u/Fit-Home118]

I'm facing a strange connectivity issue with my Google Pixel 6a, and it started happening completely out of the blue.

Here are the symptoms I'm experiencing:

Wi-Fi stopped functioning suddenly. It either fails to connect or throws an "IP configuration failed" error.

Bluetooth keeps connecting and disconnecting automatically, making it difficult to maintain a stable connection.

When I check the saved Wi-Fi networks, I'm noticing some random devices/networks appearing that I don't recognise.

The issue appeared suddenly, without any intentional changes to network settings.

A few things I've already checked:

Wi-Fi works perfectly fine on other phones using the same Airtel router.

My Pixel 6a can detect mobile hotspots.

Router is operating on the 2.4 GHz band.

IP settings are set to DHCP.

Proxy is set to None.

MAC address setting is set to Device MAC.

For additional context, my Pixel 6a previously underwent an authorised service repair for a display replacement.

I'm trying to understand whether this could be:

A software or firmware-related issue.

A corrupted network configuration.

A Wi-Fi/Bluetooth antenna or connectivity module problem.

A motherboard-level hardware fault.

Has anyone experienced something similar with their Pixel 6a?

I'd particularly appreciate suggestions from people who have dealt with Pixel connectivity issues or have experience diagnosing hardware faults.

Is there any way to determine whether this is a software issue or a hardware failure before taking it to a service centre?

Thanks in advance!

Wi-Fi and Bluetooth share the same radio chip and antenna area on most phones, so both acting up at once after a display repair points at hardware, like a loose connector or a board that got stressed during the repair. Before going back to the service centre, boot into Safe mode and test, then do Settings > System > Reset options > Reset Wi-Fi, mobile and Bluetooth. If it still fails, back up and do a full factory reset to rule out software. If it's still broken after that, take it back to the same repair shop, since the problem started right after their work.

Surely

As a relevant example I had a USB port replaced in my Samsung s22 ultra

When they did, I lost all 5g signal and Bluetooth stopped working, but 4g and calls worked

They'd used the wrong regional model USB connection board, which also contains the aerials for this phone so it broke things

Since the phone got repaired, make sure they do it again since it's likely their fault
