Repetier Host Random Crashes

Hi All

Not really a power linux user, but I can get around.
I inherited a fairly nice laptop and want to use it to run my printer.
However Repetier Host keep crashing randomly.

I saw this post, and tried the 3.13.0-46 kernel and the 4.1.12 kernel.
The 4.1.12 kernel didn't fix anything and the 3.13.0-46 kernel causes both my wired and wireless network adapter to not work......
Seems this laptop is new than those kernel versions so the adapters aren't supported?? But im not 100% sure.

Any suggestions would be really appreciated.

Thanks
