Windows 10: Why wifi and ethernet is not presented

Many days ago i face a problem to connect to the internet because it is not presented in the settings and neither wifi adapter nor ethernet adapter is not presented in the hardware connection i tried to put external adapter but it doesn't work.Note: once i had this problem i restore my laptop to last point it have access to wifi and it work till now.

WiFi and Ethernet - Both present

I have both Ethernet and WiFi on my desktop, and both work well with speeds of 210-220Mbps Ethernet and 180MbpsWifi....which is plenty for my use. But are there other criteria that make one or the other preferable? Same with my laptop, both Ethernet and Wifi.

 

WiFi and Ethernet - Both present

I was told that ethernet is more secure than wifi!

 

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.
