Internet keeps cutting off atleast 3 times a day. Network Adapter isn't detected Windows 7 either.

For the last long while, I've been suffering from this annoying issue where my internet would just cut off suddenly on this PC, while all other devices/computers in the house would run it fine. The only way to fix this problem quickly and temporarily would be disconnecting my modem and router which is quite the pain. I've looked around the internet and everyone says to go into Device Manager and find your network adapter and untick the "Allow the computer to turn off this device to save power." I was able to do this, to no avail, but the weird part about this is that the network adapter was not found under the "Network Adapter" tab. In fact, there is no "Network Adapter" tab at all. The adapter, Realtek PCIe GBE Family Controller, is found under the "Unknown" tab in the device manager. Is this a common issue that can be fixed? Also, is it the reason for my constant disconnections? I'm not sure what to add, so please tell me if you need more information, which you probably do. BTW I rushed this so forgive me if it's hard to understand.

My Router is D-Link DIR-615.

It's listed as "unknown" because you don't have the network drivers installed on your computer. Usually it won't connect to the internet at all when that happens, but it must be half-working on a generic Windows driver. You should be able to download the correct network drivers from your motherboard manufacturer's website.

Under Device Manager, DELETE the device. Reboot to force it to refind and reinstall the driver. Check under Device Manager and see if it is under Network Adapter now, if still under Unknown, then your driver is corrupt (FYI the Realteck PCIe GBE is your WIRED connected NOT your WIRELESS).

Make sure you aren't WIRED AND trying to connect WIRELESSLY at the sametime. That confuses Windows, you can only be WIRED *OR* Wireless. I would suggest turning off the wireless (some switch on the side if this is a laptop or just right click in Device Manager the Wireless and select disable) if this is the case.
