5th Fix (Replace Your Network Adapter)

All of these support fixes will be able to help you if ever your computer is experiencing a Realtek software related issue.

If all of the above methods didn’t work, then it’s not a software related issue anymore – it’s more of a hardware issue.

In that case, you’re going to have to buy a new PCIe network adapter as your old one is most likely worn out already. You can buy one from computer stores for a very reasonable price. The technicians can even install it for you.

Of course, you should only do this once you’ve already confirmed that the Realtek issue is a software issue.
