I have a weird problem with wake-on-lan on my Realtek card. After turning wake-on-lan flag on (using either ethtool or NetworkManager), to make the PC responsive to wol packets I have to first suspend and wakeup it once manually (hitting any key or power button). After this maneuver, I can wakeup via magic packet from all subsequent suspend transitions AND also from the first shutdown. Then I have to repeat the manual suspend/resume cycle to make it work again. A similar problem was mentioned at https://forums.centos.org/viewtopic.php?t=71861, but the proposed solution (forcing autonegotiation on) didn't work for me. The PC is a Gigabyte NUC-like barebone: https://www.gigabyte.com/Mini-PcBarebone/GB-BLCE-4105R-rev-10. BIOS is up-to-date and doesn't show any "obvious" wol settings. Here's some infos (just ask me if more are needed): # dmesg | grep XID [ 5.738979] r8169 0000:02:00.0 eth0: RTL8168h/8111h, b4:2e:99:78:73:cf, XID 541, IRQ 126 # lspci -k (...) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
