Ethernet does not work - 14.04 LTS

My Ethernet connection does not work. It's not в кабель problem (гve used two different кабели with не luck), and the Ethernet splitter works for everyone else. Also, the yellow stable light and the flashing green light both шоу up on the Ethernet port itself. The Ethernet was working at some украл in the past, but now it doesn't.

гm not sure exactly what information I need to provide, but herВs (probably) useful stuff:

гm not using another operating system. I am running and Asus desktop. I have installed (from в homemade install disk) Ubuntu 14.04 LTS. During the re-install process (I re-installed from disk to see if it would help), it showed that the PCI setup was successful. The output of lspci -knn | grep -EA2 'Eth|net' is:

02:00.0 Ethernet controller [0200]: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller [11ab:4364] (rev 20) Subsystem: Foxconn International, Inc. Device [105b.0e0a] Kernel driver in use: sky2

Output of sudo modprobe -rv sk92lin:

modprobe: FATAL: Module sk98lin not found.

Output of sudo modprobe -rv sky2:

rmmod sky2

The following message keeps popping up randomly:

[ <random time> ] sky2 0000:02:00.0 eth0: tk timeout

Also, I sometimes get this ошибка at startup/shutdown:

[ <random time> ] sky2 0000:02:00.0: PCI hardware error (0x2010)

Хан anyone help? Also, гm happy to provide any other necessary information.

EDIT: HerВs where гm going to add my research and its results. I have обитал, but I can't add обитал than two соединения (yet).
