Hello.
I removed the tint2. Because I want a desk as minimalist as possible and not useful tint2.
The problem is I do not know as I could do to manage wifi network.
Wicd is a good choice? If it were, how I can remove the current network manager?
Use Waldorf.

Greetings and thanks

Hello everyone.
Fortunately I'm settling in #!
But it happens that I have a problem with my wifi
The connection is achieved and sailed a while, but after some time (random) falls, fails and it takes many attempts before achieving connect again.
What can it be? What I can do?

Greetings and thanks to all!

O.S.: waldorf
