RTL8111/8168B PCI Express Gigabit Ethernet problems Ubuntu
Okay, I had posted on here awhile back about a wireless card that was giving me trouble, but it doesn't seem like there was a good solution out there, but that's beside the point, I have now hooked the box into a wired connection ready to enjoy the internet at my fingertips again. but alas, the ethernet card does not work...
I have done some searching and the solutions i've found are a couple years old and i cannot get them to work, or they simply mean i must buy a new ethernet card... woohoo.
anyway, if i could get some help first, that would be excellent, I am running Ubuntu Studio 9.10 64-bit, the wireless card is RTL8111/8168B PCI Express Gigabit Ethernet

okay, i did some hunting, and found me a driver on realtek's site, downloaded it, and got it installed and everything, and tried to configure it using the included instructions:
<Set the network related information>
1. Set manually
a. Set the IP address of your machine.
# ifconfig ethX "the IP address of your machine"
b. Set the IP address of DNS.
Insert the following configuration in /etc/resolv.conf.
nameserver "the IP address of DNS"
c. Set the IP address of gateway.
# route add default gw "the IP address of gateway"
2. Set by doing configurations in /etc/sysconfig/network-scripts
/ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network
/ifcfg-ethX for SuSE. There are two examples to set network
configurations.
a. Fixed IP address:
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=ethernet
NETMASK=255.255.255.0
IPADDR=192.168.1.1
GATEWAY=192.168.1.254
BROADCAST=192.168.1.255
b. DHCP:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
<Modify the MAC address>
There are two ways to modify the MAC address of the NIC.
1. Use ifconfig:
# ifconfig ethX hw ether YY:YY:YY:YY:YY:YY
,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.
2. Use ip:
# ip link set ethX address YY:YY:YY:YY:YY:YY
,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.
<Force Link Status>
1. Force the link status when insert the driver.
If the user is in the path ~/r8168, the link status can be forced
to one of the 5 modes as following command.
# insmod ./src/r8168.ko speed=SPEED_MODE duplex=DUPLEX_MODE autoneg=NWAY_OPTION
,where
SPEED_MODE = 1000 for 1000Mbps
= 100 for 100Mbps
= 10 for 10Mbps
DUPLEX_MODE = 0 for half-duplex
= 1 for full-duplex
NWAY_OPTION = 0 for auto-negotiation off (true force)
= 1 for auto-negotiation on (nway force)
For example:
# insmod ./src/r8168.ko speed=100 duplex=0 autoneg=1
will force PHY to operate in 100Mpbs Half-duplex(nway force).
2. Force the link status by using ethtool.
a. Insert the driver first.
b. Make sure that ethtool exists in /sbin.
c. Force the link status as the following command.
# ethtool -s ethX speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION
,where
SPEED_MODE = 1000 for 1000Mbps
= 100 for 100Mbps
= 10 for 10Mbps
DUPLEX_MODE = half for half-duplex
= full for full-duplex
NWAY_OPTION = off for auto-negotiation off (true force)
= on for auto-negotiation on (nway force)
For example:
# ethtool -s eth0 speed 100 duplex full autoneg on
will force PHY to operate in 100Mpbs Full-duplex(nway force).
<Jumbo Frame>
Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please change mtu by the following command.
# ifconfig ethX mtu MTU
, where X=0,1,2,..., and MTU is configured by user.
RTL8168B/8111B supports Jumbo Frame size up to 4 kBytes.
RTL8168C/8111C and RTL8168CP/8111CP support Jumbo Frame size up to 6 kBytes.
RTL8168D/8111D supports Jumbo Frame size up to 9 kBytes.
but i did not get very far. down to 1c. actually... any help?

Hello.. I have a similar problem.. I'm getting the "Capabilities: <access denied>" error on the exact same Realtek controller.
Would you please let me know how you solved your problem? Even reinstalling Ubuntu doesn't help... Thanks!
EDIT: I realize "access denied" is just a permissions, resolved by sudo... Still, I'm having this error and am curious for help.. here are the basics:
Atom 330
Ubuntu Maverick 10: 2.6.32-24-generic
(same problem with 2.6.32-33 and the latest, Natty, 2.6.38-10)
Realtek RTL8111/8168B PCI Express Gigabit Ethernet Controller
ifconfig shows my device as eth0:
Code:
$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:e0:4c:68:76:0b
