Windows 10: ethernet and wifi work on all devices but my windows ten pc

I have been spinning my wheels about this for several days now and haven't gotten anywhere. I do not have internet access with ethernet on my pc, I have tried different cables and different ports on the router with no luck. I have tried other devices with the same ethernet and they work fine, leading me to believe its a problem with my pc. When I run the troubleshooter it says that it couldn't find the problem. my ethernet drivers are up to date aswell.


another issue possibly unrelated but I figured id include it is that I receive the error code 0x800706d9 when I try to update windows. I found online that this meant that I needed to turn on windows firewall, however, when I go to windows firewall in control panel no matter what I click on I get the message: "update your firewall settings Windows defender firewall is not using the recommended settings to protect your computer" and when I click "use recommended settings" nothing happens.


after the above dificulties, I went to services and tried to start it manually but it fails with error code 87.


after all of this, I am very stuck. Any help to fix my ethernet issue would be greatly appreciated.

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, Ethernet won't

WIFI Works, not ethernet. I have a MacBook Pro and a Dell WIN 7. Ethernet stopped working, replaced WIFI Access point. 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. Frustrated in Hobart*Bang Head :banghead:
