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...

 

WIFI Works, Ethernet won't

OK but why?

NOT YELLING, JUST EMPHASIZING

Please note, I installed the new Lynksis, it worked just fine for 3-4 days on both my MACBOOK PRO when in ethernet connect and the Dell, then the ethernet just quit working for both my MacBook Pro and Dell desktop. It did work, then just quit for no apparent reason. WIFi for iPhone, iPad, Andriod Phone, and when I set to wifi for my MacBook pro all work fine.

Detailed history: I first noticed that on my Desktop dell that is CAT5 ethernet connected to the WIFI ROuter, that it stopped, no internet access. I began to trouble shoot, and turned off my WIFI on my MAcbook and it wouldnt work either, plugged into same router but different cat5 cable. At that time, all WIFI devices still worked. I figured that it must be the ethernet side of the WIFI router, so I replaced the router with brand new one. the Lynksys N900 listed in original thread. Ethernet and everything worked just fine for 3-4 days. But then ethernet quit, but wifi still works.

Whatever the problem, it affects both my MacBook Pro and Dell with WIN 7. I'm guessing it is NOT a computer problem, if it is it is affecting both my Mac and Dell, separate cat 5 cables to same wifi router

To remixedcat, I don't know for sure how to check IP settings, see above post, no damage apparent to anything.

 

WiFi works, but not ethernet. New router, new cable. Does not work on other devices

Same Problem, Go Figure

I have same problem WIFI Works, not ethernet. I have a MacBook Pro and a Dell WIN 7. I replaced the wifi access point, and for several days, it worked! But then about a week later, I can still connect wifi just fine with all devices, but not ethernet. DID you ever get yours figured out? Frustrated in Hobart*Bang Head :banghead:
