Realtek Ethernet Limited to 10mbps

[Mithallas]

I used a wireless connection for a couple years. I moved and now I want to use a wired connection. The adapter just says "network cable unplugged" with the newest(2015) Realtek driver. The only way I can get a wired connection is by rolling back the driver to previous(2013) version and change speed and duplex to 10mbps.

I plugged the 25ft cat6 into my roommate's computer and successfully connected @ 100mbps.
Observation: When my roommates computer successfully connected, it displayed the custom network name that I set. When using the 10mbps on my computer, the network name is generic Linksys578

I would like to get internet without bottlenecking myself.

Any help is appreciated
