========================
Detailed description：The signal strength of Intel Dual Band Wireless-AC 8265 chip deteriorated over night. I can only detect a wireless network if the unit is less than 5 metres away from router. Reloaded drivers and sent the unit in to the local ASUS repair center. Finding was that chip was damaged in some way.
Is there another possibility?

Hello Donald,
Is there any issue with the repair center that you would like to ask for more issue cause or verification?
Thank you.

The repair center was unsure what the fault was. I would just like to know if they may have missed something. The unit less 18 months old and I was told that the only way forward was to replace the main board. This is very expensive.
Just disappointmen.

Thanks
