Laptop Loses Wifi Connection and I Can't Reconnect Without Rebooting

I fixed the problem by changing one setting. I went to Device Manager, Network Adapters. I selected my adapter and then right-clicked. I selected Properties, then Power Management. I then deselected "Allow this computer to turn off this device to save power."

I have a Lenovo T450S laptop with Windows 10 installed. For the last three or four days I've been having a problem with Wifi. The Wifi disconnects periodically and I can't reconnect it to my home network without rebooting the laptop. When I go to Settings and Status, the system tells me I’m not connected. When I click Show Available Networks the only option I see is airplane mode. There are no available Wifi networks.  I have tried running the Windows network diagnostics tool and it says it can’t identify the problem. I rebooted my router and modem but that didn’t help. I tried updating the network adaptor driver but Windows says the driver is up-to-date.

The Wifi problem started after I installed some Windows updates. There were two Microsoft Windows Updates on 1/15: KB4528760 and KB4532938. There was one security update on 1/14: KB4528759. I don't know whether the updates are related to the problem but the timing is suspicious. Can someone please tell me what I should do next? Thanks.

I had the same problem.  Tried every fix I could find - adapter driver update, removal and reinstall, disable and enable, etc.  Nothing worked so I restored my Windows system to 1/10/2020 before the updates and everything works fine now.  After further testing, I intend to install updates one at a time until I find the culprit.

We shouldn't have to do this, especially when Windows forces updates on us.

Same. Exact. Issue. I'm on a HP Spectre but the details of your issue are exactly the same as mine. I am certain it has something to do with the recent updates.

Wifi disconnects and I have no option but to reboot.  Show Available Networks yields only airplane mode as a clickable option. It can't detect any Wifi networks even when other people in the home are actively using the wifi. Windows network diagnostics sees no issue. Driver is up-to-date.

The Wifi problem started after I installed the following updates on Jan 18th. 

KB4528760 and KB4532938   Looks like at least 6 others have this same issue as of this post so obviously this is an issue. I'd rather not restore back to pre Jan 18th but I can't deal with having to reboot 10 times a day for more than another few days. Please offer some guidance MSFT.

I had this problem too after the latest update on Jan. 15.  I did the power tick and it made no difference same with driver updates.  I just uninstalled the updates going backward one at a time.  Lucky for me I hit it on the second one - KB4528760 .  Once I had uninstalled KB4528760 and then reinstalled the network drivers everything was back to normal .  As soon as Microsoft pushed the update again the network failed.  I have stopped updates until Microsoft has an update to fix this issue.

Thanks. I'm pretty sure the problem has to do with a recent update. A Windows restore is my next step.
