IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

 

IP configuration not valid - interference from ethernet adapter?

I tried both of these solutions (have same problem, but to expand, my wireless doesn't connect to the internet either), and neither worked. Have intel AC 7260 wireless, and Atheros AR81g1 Ethernet (NDIS 6.30). Hope someone comes up with a solution soon. Windows 10 has been working....well, OK, for about a year on my personal laptop. My system bricked when I installed the Windows 10 Anniversary edition. Had backup on 2TB external drive. I installed clean windows 10, and all worked fine, including internet access on both wireless and ethernet, but needed to reinstall from my backup because of a lot of programs, and data there. Backup was about a month old (yeah, I know, backup more frequently). After a successful backup, I again attempted to install anniversary update. This time it installed successfully, and all appeared good until I tried to access the internet. Now my case is per above. Can't access from either Ethernet or wireless. It connects fine to my router (which I'm connected to on my company laptop right now), but it will NOT connect to the internet. HELP!!

 

Issues with integrated Ethernet and PCI-E Ethernet adapters


Hello,

Recently my on-board Ethernet port stopped working. At first I noticed that I no longer had the Wired Connection in the bottom right of my taskbar, instead replaced by the Wi-Fi symbol. I checked to make sure that my ethernet cable was plugged in, and that the lights on either side of the cable were blinking. They were. I then checked my Device Manager to make sure the driver was still there. It was. The only issue I could see was that my ethernet adapter no longer showed up in my network settings, only my Wi-Fi adapter was listed. I noticed in Windows Update, it mentioned that it failed to install a driver for a network component, so I decided I would look for the most up to date driver for my ethernet adapter online, and install it myself. Here is where the real trouble started; Every time I try to uninstall the driver for my ethernet adapter, including when I tell it to delete local files, it comes right back. I've tried disabling it first, and then uninstalling, and even completely disabling my windows update, and automatic device installer, but it still comes back every time. After a few hours of trying this with no luck, I decided to just run Recovery, and luckily it gave me a restore point to just before it ran the last Windows update. After recovery ran, everything worked, until I shut my computer off. When it booted back up, the ethernet adapter was missing again. Went through the same steps; Recover and wait. This worked, and I disabled Windows Update, and it has worked since. However, this fix isn't good enough for me. I want the latest updates from Microsoft, so I just decided to buy a new PCI-E Ethernet Adapter, and hope that would work better. I installed the card into my computer, and it didn't show up in my list of network adapters either, yet the driver for it shows up in device manager. I can also not uninstall this driver. What is wrong with windows? Why can I not delete a driver and just have it list the hardware under Other Devices as an unknown device? Is there some firewall setting that stops me from deleting drivers? Any help would be greatly appreciated.
