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?

sorry to keep posting but i believe i have found the problem, but i do not know how to fix it... i ran an lspci -v and noticed that for every output i got a "compatibilities: <access denied>"... how can i resolve this?

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:
