Fedora 20 network issues

[CS DBA]

Hi all;

I'm setting up Fedora 20 on a Lenovo W540,

I'm seeing network issues :

- The wireless connections seem unusually slow and I get disconnects often
- The wired connection often will not connect at all

The wireless card is :

Intel Dual Band Wireless 7260AC

However I'm not sure why this affects the wired connection

Can anyone help me debug this?

Thanks in advance
