I know similar questions have been asked in the forum in the past, but I cannot get the exact answer I need: hence, resorting to a new question.
A month ago, my system with r1869 driver module worked properly without any problems. However, now, it doesn't - no network connectivity on eth0 (wired). I solved this by the normal method of going to the Realtek website and installing their module (r8168). Now the system works normal again.
I am sure I had some or the other change which triggered the behaviour but cannot, for the life of me, remember what was the change.
My question is this - what could have possibly caused the r8169 module to stop working? Kernel updates? Any recent Ubuntu patches? (though I do not install any updates as I want stability on a working setup)
