December 21, 201312 yr Hi all I am having an issue connecting to the network switch (linksys se2500) at 1 Gbp/s, it will only connect at 100 Mb/s. I am using unraid 5.0.4 on an Asus A85XMA which utilises the Realtek 8111F NIC. The cables are not the problem as when I connect the lan cord into a PC next to the server it successfully connects at 1 Gbps. Any suggestions are much appreciated Thanks Thermo NIC info (from ethtool) Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes NIC driver info (from ethtool -i) driver: r8168 version: 8.037.00-NAPI firmware-version: bus-info: 0000:03:00.0 Ethernet config info (from ifconfig) eth0 Link encap:Ethernet HWaddr ac:22:0b:75:13:31 inet addr:192.168.0.8 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:26312070 errors:0 dropped:1 overruns:0 frame:0 TX packets:12065205 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:715087944 (681.9 MiB) TX bytes:715862410 (682.6 MiB) Interrupt:47 Base address:0xe000
December 22, 201312 yr The PC network adapter may be more tolerant of the poor quality network cable than the one on the MB. Try a different cable.
December 22, 201312 yr From my commentary in the motherboard section describing the issues I had maintaining a gigabit connection with this board. I replaced my switch and this appears to have completely resolved the gigabit LAN issues at boot and wake. Now the on-board Realtek nic consistently works as it should, as does the PCI express Intel nic. Neither of them are degraded now when the USB flash drive is connected to rear ports. NIC bonding also works fine with both nics at 1000 mbps. [My] new switch is the inexpensive and well-reviewed TP-Link SG108. It meets IEEE 802.3u and 802.3ab standards while the old 3Com switch is just 802.3 compliant. Possibly that is the difference-maker or perhaps the old switch was just failing. I'd suggest checking the specs on your Linksys switch, and upgrading if it doesn't meet the more recent standards.

Tried 3 different cables - 2 claiming to be cat5e and a cat 6 - the cat 6 worked Based on Lewcass's experience, this NIC seems to be very temperamental indeed! Thanks for your help Thermo
