The above mentioned "Devices" are components which aid IPv4 and IPv6 interoperability.
If this is a home PC (or even for most small businesses that haven't switched over yet) this is not important and can be disabled.
You can check if you are using IPv4 or v6 addressing simply by opening command prompt and entering ipconfig. If the IP address is in XXX.XXX.XXX.XXX format it is IPv4. An IPv6 address will be twice as long and will also contain letters. Assuming you are using IPv4 continue with the below.
Open the Network and Sharing Centre and Select Change adapter settings. Inside there, right click your Local Area Connection and select Properties.
You should see a checkbox (Tick box) list of components your adapter uses which should contain both "Internet Protocol Version 4" and "Internet Protocol Version 6". Remove the tick from "Internet Protocol Version 6" and then restart your PC and see if that makes any difference.
It may also be worth resetting the tcp/ip stack if you have not done so already.
Open a command prompt with administrative rights by clicking the "start button" and then typing cmd. Right click on the cmd program result and select run as administrator.
Enter the following commands and please post the content of the text file created in the root of the C: drive. You may need to restart your PC again for the changes to have any effect.
- netsh int ip reset C:\netsh.log.txt
- netsh winsock reset
Let's see if this makes any difference. There are some automated tools that will reset virtually every aspect of your network configuration but I believe it is better to try a couple of the common resolutions first, though that may be our next step if the above fails.
