Realtek RTL8101E Wired Ethernet Random Disconnection


Hello Everyone,
I have this wierd problem with my realtek rtl8101e ethernet. It keeps on disconnecting randomly with my router.
My computer is connected to D-link router via LAN cable.

this problem does not occur in my windows xp os.

I have to suspend and resume my Debian os (wheezy 7.6 KDE) to get the ethernet connection up everytime it disconnects with my router.

These are my ethernet details
Code:
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
        Subsystem: Realtek Semiconductor Co., Ltd. Device 0123
        Flags: bus master, fast devsel, latency 0, IRQ 42
        I/O ports at e800 [size=256]
        Memory at fdfff000 (64-bit, prefetchable) [size=4K]
        Memory at fdff8000 (64-bit, prefetchable) [size=16K]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Endpoint, MSI 01
        Capabilities: [b0] MSI-X: Enable- Count=4 Masked-

        Capabilities: [140] Virtual Channel
        Capabilities: [160] Device Serial Number 09-1b-00-00-36-4c-e0-00
        Kernel driver in use: r8101
I have already removed the driver that came with the default debian installation and installed the drivers from realtek website but the problem still persists.

Hi:

Maybe the realtek driver is not enough?

Just an idea, maybe try installing the driver for your motherboard/chip set will help.
To find that information run:
Code:
lspci
Go to the Debian WiKi that may help.
It's http://wiki.Debian.org/DebianLAN

Realtek drivers tend to do this, not sure why. Maybe a newer kernel will help.

Agreed; sometimes installing a newer version of the kernel makes performance and hardware issues fade away.
I'm not sure what kernel Debian Wheezy comes with.

However that's easily remidied by running :
Code:
uname -a
Or uname -r

When you have time; navmom,
Run uname -a to see what kernel your Debian installed with.

I'm not sure if you would upgrade your kernel or install a new kernel all together.

You may also want to post what make and model your router is so others can help and chime in.

Yes I think you are right because I have this problem with other debian based distribution such as Ubuntu and Linux Mint.Linux Mint Kde edition was the worst (just too much random disconnections) with kernel 3.13. In Debian the connection is still much stable (disconnection takes place randomly within in 2 or 3 hours.) else Debian wheezy KDE with kernel 3.2 is awesome (fast and stable).

I have also tried Arch Linux recently but same problem even on non debian based distribution.

I am not willing to install new kernel I just prefer stable kernel 3.2.0-4 I believe this problem is worst in newer kernel (say 3.13).

Report the problem to the driver developers, maybe they will try to fix it.

The newer kernels in backports are still stable, and are trivial to install.

Installed the latest kernel 3.14 from wheezy backports and 2 days of usage the problem still persists.
Its not very annoying but common this is not what is expected from realtek drivers
