I have a dell Inspiron 3847 running W8.1/64. My realtek network adapter(Realtek PCIe GBE family controller) quit working. I did a system restore but the problem it's still on. I had a similar problem with my old computer(dell inspiron W7/64)and to resolve the problem, back then, I uninstalled de realtek network adapter then restarted my pc. The adapter then automatically reinstalled itself and problem solved. However, when I tried to do the same thing on W8.1. the uninstall meter kept running for about 25 minutes. If there's one thing I know is that no program uninstallation takes 25 minutes or more. Can somebody give me any suggestions in how to reinstall this adapter or how to fix and get it working again.
