Hi!
I follow the instruction from the README.Debian file in r8168-dkms_8.048.03-1_all.deb. This is a HP laptop connected to a 150 Mb/s. The HP service claims the card should be working with the speed up to 300 Mb/s. Both tests and Setting show the speed of 100 Mb/s only. For videoconferences the difference can be quite essential.
