Connection Issues Basics!

Winsock Reset
Winsock, is a technical specification that defines how Windows network software should access network services, especially TCP/IP.

Windows comes with Dynamic Link Library (DLL) called winsock.dll that implements the API and coordinates Windows programs and TCP/IP connections.

But sometimes Windows Sockets or Winsock may get corrupted as a result of which you may not be able to connect to the Internet. It may therefore need to be repaired.

To reset Winsock in Windows 10 / 8 / 7, open CMD as admin, type the following and hit Enter: netsh winsock reset

Want to go further? This is not needed but doesnt hurt, you will probably be only using IPV4 when you are connected to the internet.

If you are using IPv4, type netsh int ipv4 reset and hit Enter
If you use ipv6, type netsh int ipv6 reset and hit Enter.

DNS Flush
If you are running into a lot of “Page Not Found” errors and you’re connected to the internet, you may need to flush your DNS cache.

Open the command prompt. The command to flush DNS needs to be entered in the command prompt. Accessing the command prompt is slightly different depending on which version of Windows you are running:

    Windows 8 - Press the Windows key + X and select “Command Prompt

Use the DNS flush command. Type ipconfig /flushdns and press Enter. A message will appear stating “Windows IP configuration successfully flushed the DNS Resolver Cache”.

------------------------------------
Update drivers - Go to motherboard manufacturers website, look up your motherboard spec's for the LAN you are using, You can find the appropriate Driver under "support" or "downloads" usually (Good idea to cheak for Bios updates & driver updates to install while you are there)

-----------------------------------
Upgrading Hardware - Buy a Cat6a Ethernet cable & any modern hardware.

-----------------------------------
TL;DR:
CMD prompt & type in:
IPCONFIG/FLUSHDNS (hit enter)

netsh winsock reset(hit enter)
(reset PC)
