Windows 10: I just bought a realtek wifi extender for my house. And it isnt working. Why?

I have the extender set up and everything. I have attempted to connect using WPS but on the manual it says there should be a red light that pops up for 5 seconds. And says it would reset when connecting but fails every time. Is mine just broken?

WiFi extenders and BOSE lifestyle system

I have Wifi extenders that work great with the internet in the house. We also have a BOSE Lifestyle system is not working with the main unit in the Family Room. Can I have the WiFi extender help? How do I do this?

 

WiFi Extender Questions

I went with the Netgear model EX6110 Extender and so far I'm happy with it. I used my laptop in the shed last night. The signal was strong and steady. Before I setup the extender the signal kept fading in and out.

 

Realtek wifi adapter isn't working

This problem started a few days ago. Initially I thought it was due to a dead spot in our home. After a few days I realized that was not the case. The troubleshooter narrowed it down to the Realtek wifi adapter. I went to
the Network adapters under Device Manager. There was an indicator there (the yellow triangle I think). I checked for driver update, there were none. Received a "message" that I had the driver recommended and/or up to date. I found info suggesting I roll back
the driver. That option is not available. I found suggestion to uninstall the network adapter, restart and hopefully that reinstalls the driver. That didn't work. The Realtek adapter that I initially was dealing with is now gone. I had other messages in Device
Manager saying the adapter couldn't start code 10 and couldn't be found. I currently have Realtek PCle FE Family Controller listed. I think that was there before but not the wifi adapter initially identified as this problem. This controller seems to be ok.
I found information suggesting some type of installation or update could be the culpret. I had recently upgraded a program so did a system restore back to before the update. Initially this seemed to work but now the problem is back. I found information about
generating a wlanreport but received "failed, error is 0x3A98." I found this Fix Wi-Fi connection issues in Windows - Microsoft Support. I don't believe the problem is the router, modem, etc. basic issues. Ethernet cable works
but that was never the issue. I did not turn off firewall, antivirus protection, etc. as that seems irrelevant and I'm hesitant to do anything anymore. This only other thing on this list that I haven't done is the network reset. Again, hesitant to try anything
else, especially when this article says "last resort." It appears to me that I have completely lost the ability to use wifi and that the realtek adapter needs to be turned back on or reinstalled and nothing else I've seen seems to offer that solution. I tried
virtual assistant which led to some of the suggestions. I thought there was a chat available, can't find it. I don't see what the Skype option is supposed to do; it doesn't seem to "call" anyone.

Trying to find more Realtek info in history: Realtek RTL8821ae wireless lan 802.11ac may be the actual adapter that no longer shows up.
