Re: Realtek RTL8111C Controller Compatibility
said by ozar  :said by ozar :I took it out and replaced it with a card that uses the 8139 Realtek drivers, and that worked. Had that failed, I was going to try the old standby, Linksys LNE100TX card that I have on hand. I'm finding that Realtek chips and Linux don't mix well at all, at least for me. Let's be fair, they don't work well in any OS.  I'm still using the Realtek on my Gigabye EP35-DSL until it gives me a reason to replace it, but everywhere else it's Intel's e1000 (PCI or PCI-E). 3com's 3c905 series were hot back in the 100 Mbit days, as well.

lol... the LNE100TX is working great for me, at least so far!
I'll probably keep using it until it gives problems, or until I get the onboard controllers to work.

I have had no real problems with realtek cards (other than the old 10mbit ones.)
My 2 r8169 cards work with no problems other than an occasional problem on warm boot (reset switch fixes issue.) My PC's are rarely restarted. They even support NAPI.
All my 10/100 realtek cards work flawlessly.
Gigabit cards have been a problem until recent kernels. the drivers are new. My Marvell Yukon did not work for a long time in linux.
PCI-E is also new.
Oh, the LNE100 is buggy, don't even attempt it. I find them to be the worst cards made.
What do you mean by "connection issues". Like I said I had problems with the realtek cards restarting on a warm boot. Switching between compiled-in vs module usually fixed it. Powering dow/up the switch seem to usually fix it (unplugging/plugging the cable did not.) They always worked on a cold boot.

The Realtek driven network card that I employed to temporarily fix the original problem started giving me connection issues, so I've now moved on to the Linksys card described above and all is well, at least until the real issue is fixed.
This last week of pure frustration has taught me to think carefully before purchasing any more hardware for my Linux box that is driven by Realtek drivers. When, and if they begin to show better support for Linux, I'll have another look at their efforts.
Thanks to all that replied!

Update...
I've tried just about everything I can think of, but nothing works. I've also found a patch to supposedly fix this, but it's for the 2.6.26-rc6 kernel:
»userweb.kernel.org/~romieu/r8169/2.6.26-rc6/
In the interim, I've finally got internet under Linux again, but the real problem (8111c chip & r8168/r8169 driver) remains unsolved.
After digging around in my spare parts box, I put a Cnet Pro200WL card in that uses the 'tulip' driver, and it didn't work. It showed as UP in ifconfig, but nothing would go up or down across the connection. I took it out and replaced it with a card that uses the 8139 Realtek drivers, and that worked. Had that failed, I was going to try the old standby, Linksys LNE100TX card that I have on hand.
Now all that's needed is a fix so the redundant card can be removed and I can use the default controllers on the new motherboard.
