So I'm on Fedora 20 and my wired ethernet is stuck on "Connecting". I've already upgraded the driver to r8101. As I look at it now, the white light on it is on constantly and the orange light never is. Here is the device info from lspci:

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
    Subsystem: Hewlett-Packard Company Device 3672
    Flags: bus master, fast devsel, latency 0, IRQ 42
    I/O ports at 4000 [size=256]
    Memory at c0404000 (64-bit, prefetchable) [size=4K]
    Memory at c0400000 (64-bit, prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: r8101
    Kernel modules: r8101

Upon running ethtool, I get this:

Settings for em1:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
    Supported pause frame use: No
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/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
Cannot get wake-on-lan settings: Operation not permitted
    Current message level: 0x00000033 (51)
                   drv probe ifdown ifup
    Link detected: yes

And doing ethtool -i, I get this:

driver: r8101
version: 1.025.00-NAPI
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

Everything seems to be okay here to me, but maybe I'm missing something. Anybody have a suggestion as to what to try, or maybe another debug to dump? Any help, no matter how small, is appreciated!

Hi! Welcome to Ask Fedora! What's the output of dmesg when you plug in your LAN cable? Please edit your question to provide the information. Thanks.

In terminal, do ifup em1.

Also, try setting a static IP in /etc/sysconfig/network-scripts/ifcfg-em1.
