Arduino yun newbie

Just got a new yun and everything was going well until I updated the new wrt and the wheels fell off. I should have stayed with the older and played around before I tried to update. However. now I have no wifi connectivity:(

Im also learning linux at the same time so I'm a sucker for punishment. Im trying to get off the microsoft bandwagon.

I have tried to access via the network through the adrino ide but keep getting an error message evertime i mess around with a connection. I'm using the manjaro linux destro.

I have messed around with this for 3 days looking at the forms and google searches and no luck.

Can anyone point me in the direction of some easy to understand direction or some videos to help me get back on track with this yun? Ive been through the posts but not understanding the input.
