I need some body give me insight in this issue:

i have damn toshiba satlellite C850-A989 with ubuntu 13.10 installed, the wireless card work fine. BUT the ethernet controller not working. and i dont know if i have problem in my preinstalled (default) driver or not.

this is a output of:

:03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller

I downlaoded the RTL8101E/RTL8102E driver from official realtek website from this link:

and I start installing the driver from source code, but ending with error

make[3]: *** [/home/manee/Downloads/r8101-1.024.00/src/r8101_n.o]  Error 1
make[2]: *** [_module_/home/manee/Downloads/r8101-1.024.00/src]  Error 2
make[1]: *** [modules] Error 2
make: *** [modules] Error 2

I looked into and I found there is a patch must be putted in src folder, I putted the patch but the same error still there.

What's the output of sudo lspci -nnk -s 00:03:00.0? Also dmesg | grep -E 'eth|too' and nm-cli. Edit your question and add the information. – Braiam Dec 8 '13 at 11:33
Please edit your question. – Braiam Dec 8 '13 at 11:57
From the this morning i start over again, but ended with a bug in the 3.11.0-14-generic kernel, the bug says the r8168-8.036.00,(which is the patch) fails to compile under 3.11.0-rc7 – Manee Osman Dec 8 '13 at 12:06
This is patch name put it in google to see more details about this bug r8168-8.036.00-kernel-3.10.10.patch – Manee Osman Dec 8 '13 at 12:13

To expand on my previous answer (comment), I suggest that you either (a) verify that the realtek adapter is working fine with a different OS (e.g., windows), or (b) assume that your initial attempt to set up the system with default drivers has corrupted the internal settings of the adapter and will require a loss of power to reset. In case of (b), remove (or disconnect) the battery from the system for a few minutes, then hook it back up and then try reinstalling the driver, with the patches in the proper location, etc.
