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. -- Scott Henion
