Windows 10: HELP! Computer no wifi/ethernet

I need help desperately!My computer did a windows 10 update a couple of days ago and i managed to reinstall it with a USB windows boot from HP. That all went well and set my device up nicely!I come to connecting to wifi and click the icon, no wifi even on there. i also noticed flight mode you cant click it or turn it on/off. I plug in the ethernet cable; it comes up but says no internet!Please can someone help asap!

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 stops working when using ethernet

If the computer is unplugged from the ethernet, does the wifi work?

 

Can't connect wifi or ethernet

So I cant get WiFi or Ethernet to work on either of my two computers with the new Windows 10 Update. I read and try to follow the recommendations (using a work computer) about the steps to take. I love that the final step if the first suggestions didn't
work, is to make sure you've downloaded the correct drivers. Could the engineers be more specific as to how you download drivers when you can't get on the internet.

Thanks.
