Windows 10: invalid IP Configuration Ethernet does NOT work. Wifi works fine

I have been trying to fix this issues for days now. I've tried everything i could think of to fix this. I even factory reset my entire PC and it fixed the issue but then it randomly comes back. The issue is the WiFi isn't' that great and Hardwired is just so much better. Every suggestion I've seen does nothing. Sometimes it just "Network" sometimes it just says "unidentified network" I've reset the network card. Uninstall reinstalled the drivers. renewed everything in Command prompt. Even flushed the DNS. I'm just lost and want this computer work properly. It was pretty pricey. CPU: i7 9700kGP

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.

 

Invalid IP Configuration and Unavailable DHCP on Working Router

Hello,

I am having an odd problem. My newly built PC began having WiFi issues just the other evening, out of the blue. I have attempted to narrow the problems as much as possible, and am at a loss. Thus far, my findings
and situation are as follows.

• I can connect to my home network with all devices. All devices work properly, except the desktop. Other devices include a Chromecast, Roku, 2 Phones, and a Laptop (occasionally).
  • The desktop network connection is listed as "No Internet, Secured" yet I am connected. It says 'No Internet" when I dive into properties.
• My Desktop can connect to my HotSpot on my phone without issue. (ruling out the hardware on my PC)
• A troubleshoot on my WiFi connection will yield one of two results.
  • "WiFi has invalid IP configuration"
    • I have attempted ipconfig /release and /renew, it tells me there is an issue with the DHCP server not available.
  • It will suggest I restart my router. (I have)
• AT&T reports no line issues, but this is obvious because other devices work.
• Manually configuring the IP to match the specifications of a working device on the network does not work
• Manually configuring it in network properties does not either
• Resetting it back to Automatic does not work change things.
• I am fully updated in Windows 10 Home

I am at a complete loss. Occasionally, it will briefly connect, but then shortly afterward I will lose the connection again. At times, it has lasted for brief periods before dying. Any help would be great,
and I can provide any additional details necessary.

 

Invalid IP Configuration

As I have noticed with many of you, I have had trouble connecting my lap top to Wifi running in Windows 10. Trouble shooter informs me that the IP address configuration is invalid. I have followed a number of the suggestions posted on the forum however the
only one that worked was to go into 'Command Prompt'; 'Run Administrator'; then type in ipconfig /renew. However this only appears to be a short term fix as it reverts back to 'invalid IP Configuration. The contact centre have been unable to help - does anyone
know how to fix it permanently?!
