I didn't realise that the Lenovo System Update had its own setting to automatically download and install driver updates, so I have now disabled that. This would be about the time that my WiFi connectivity disappeared. However, on further investigation I noted that the log in the Lenovo System Update utility showed a Wireless LAN driver update (to 18.40.0) at 10:50 am BST. The Windows update log shows no updates were applied on 26th April. I've searched high and low on the Internet and forums such as this and found nothing of any help.Īny ideas as to how I might fix this much appreciated as I am totally stuck! The Win 10 update log does not list installation of any updates at all from yesterday, so it doesn't look like it was a bad driver update.

If I turn the hardware wireless switch off and on again the network icon in the tray shows this, and will not list any available WiFi networks:ĭevice Manager says the device is working fine, and I have checked current driver version against that of a colleague with an identical X230i (which works fine) and they are the same: 15.16.0.2 dated 06/01/15. I have tried uninstalling/installing various Intel Wireless drivers to no avail. I have checked that I have not done anything basic/daft like leaving Flight Mode on. What is really confusing is that if I boot the laptop with a Fedora 22 Live USB the WiFi works absolutely fine, which appears to suggest that this is indeed a Windows driver issue and not hardware failure. Yesterday morning at around 10:30 I walked away from it to do something else, and when I came back I saw that the WiFi interface had mysteriously disappeared from the list of available adapters, and now I cannot connect to WiFi at all. My work laptop is a Lenovo Thinkpad X230i, which I upgraded to Win 10 Pro last year.
