RTL8111 ethenet adapter problems

I am installing Arch linux and I can't connect to my router or the internet, it says there is an IP but there is no connection and it won't connect.

I have had a Desktop computer for about a year now, initially I installed Ubuntu on it, which worked with a wireless USB on and off for a while, but the wireless USB device cut out every 2 seconds and there was no way to fix it, the ethernet adapter wouldn't work either, the RTL8111 ethernet adapter. So I sort of gave in and installed Windows 7. The ethernet adapter worked in Windows somehow, so I stuck with it, until now, because I am sick of Windows and everything it stands for.

There are hundreds of threads online saying the only way to solve it is with the official driver, this has never worked for me and isn't really an option for me right now because I am currently trying to install Arch linux and I can't connect to the internet. I tried the wireless USB device but it doesn't seem to work in Arch at all.

Every time I try to install linux on that machine I find myself coming back to the same threads over and over and over and over and over and over again and none of them help and they all say the same thing.

There are no errors anywhere, none in dmesg, apart from link down, link is not ready, etc.
I set a static address and ran dhcpcd on it, etc, which really should have worked, then I tried installing the newest drivers which didn't work because the installation ISO doesn't come with the kernel source or make on it.

So I'm at an impass, no idea what to do or try, ifconfig says it has an IP but it won't connect to the network at all.

If you have any advice I am willing to try anything, and if you know any Linux distro where this adapter works I wouldn't mind using that instead.

Thanks.

Re: RTL8111 ethenet adapter problems

What does sudo iw dev wlan0 scan  report?  (Note, change wlan0 for whatever is the name of your network)
Can you see access points?
Are you actually associating with the network?
When you think you are ready to run dhcpcd, check the output of sudo iw dev wlan0 link and ensure you are associated with your access point. 
If you aren't, everything else is moot.

It's not a wireless device, it's a ethernet adapter.

I did, same problem, I know it's with the adapter, it's quite a common problem, also it works in Windows.
I even got on to the router company, they said they didn't support linux.
I tried editing the router settings so many times you wouldn't even know.

Damn.  I was working from false memory as to what the RTL8111 was.  Sorry for the noise.

Re: RTL8111 ethenet adapter problems

Have you check about power saving.
I assume that r8169 is the module loaded by the kernel. Try r8169.debug=16 to the kernel cmdline. Just to see more debugging informations.
Otherwise find out vendorID and productID, to search something.

EDIT
some news, see here and here.
