Windows 10: setup windows without internet and reinstall wifi adapter

So i accedentally uninstalled my wifi adapter and after trying to reinstall it the best course of action was to reinstall windows but now i cant do that because i dont have any internet. I need help reinstalling windows and the wifi adapter.

Update made wifi adapter disapear

If the wifi adapter appears in Device manager without any warning triangle but there is no wifi section in Settings, Networks then reinstall the wifi adapter.

If the wifi adapter appears in Device manager without any warning triangle and there is a wifi section in Settings, Networks then use Settings, Update, Troubleshoot. I'd suggest this sequence:-
Hardware & devices
Network adapter
Internet connections

Best of luck,

WiFi Adapter question

To be honest, I keep losing my wifi connection and Im almost positive its not due to my internet connection or Router or anything like that. VERY often, everyday, all day it keeps happening. The troubleshooter always resolves it by "reset wifi-adapter" (I believe this is the step it takes that resolves the problem) before it happens again anyways. Its driving me nuts ! Most time when it suddenly goes out (the connection) all the networks that should be in "show available networks" or all but the one I was connected to, disappear. I run the troubleshooter and it ends in resetting the wifi adapter. And it works. 10 minutes later, it happens again. Im trying to pin down the problem here. Thank you for your help.

 

New computer setup wifi not working

I am trying to set up a new Lenovo IdeaCentre A540 Series all-in-one running Windows 10 Home. When it was walking through the initial setup, it detected several nearby WiFi networks. I had a problem getting the mouse connected and was not able to set the WiFi network. It was turned off and back on and then, upon getting back to that step, did not detect any WiFi. In Network and Internet settings it has no WiFi adapter listed and no WiFi options anywhere. I did make sure network discovery was turned on and I checked in Device Manager that the network adapter was enabled, but it doesn’t show up anywhere but in Device Manager.

Under Network Properties, it does list WiFi and says “Qualcomm Atheros QCA9377 Wireless Network Adapter”, status not present and connectivity disconnected. Under Device Manager I don’t see that adapter, it shows “Realtek PCle GbE Family Controller”, which appears to be the Ethernet adapter maybe? and a variety of WAN Miniports.

I’ve pretty much maxed out my knowledge here and I can’t find this exact issue when I search, so any advice would be much appreciated. Trying to help my stepdad set up to work from home during the pandemic...

Welp, now it's working. I realized I could show hidden devices in Device Manager, so I found the wireless adapter there. It was showing as not connected, so I shut down and dragged everything to another room and connected an ethernet cable, whereupon the wireless adapter started working perfectly. Maybe it was turning it off and back on the third time that worked, who knows...
