Windows 10: How do you configure an ethernet adapter to get internet access in Windows 11

After installing Windows 11 Pro 23H2 OS Build 22631.3737 on a Lenovo IdeaCentre 510A-151CB, I cannot get an ethernet connection to provide internet access through two different adapters. I have disabled the on-board ethernet in the BIOS and have tried a PCIe and a USB ethernet adapter with the same result. I have downloaded the latest drivers from the manufacturers with no change. I have tried the network reset function in Windows, and have tried numerous suggestions from other web sites. Device USB\VID_0B05&PID_1976\5013000001 had a problem starting. Driver Name: rtucx21x64.inf Class

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!!

 

Configure Wireless Access Point

I have an existing network using a Buffalo N300 wireless router configured as 192.168.11 and 255.255.255

I have recently purchased a Sony Bravia TV with internet capability and would like to connect a second router – the Belkin F5D-8233 – as an access point for the TV. As I already have the router, it is cheaper than me purchasing the Sony wireless dongle.

Essentially, the Buffalo is connected to my PC in one room and provides the internet access. The Belkin would be in another room, connected via Ethernet to the TV.

I have set the Belkin up to use 192.168.11.10 with the same SSID and security settings as the Buffalo. I have also set it up as an Access point.

I have connected the Belkin and the Buffalo together via the Ethernet LAN ports to try and do an initial configuration but I cannot see the Belkin when I do this even though the LAN ports light up.

Can someone give me step by step instructions on how to configure the Belkin so that it gets internet access wirelessly in the other room?

I have been able to confure the TV so that it sees and connects to the Belkin but obviously this is of little use unless it can connect to the internet through that connection.

Thanks, any help appreciated.
