Problem whith timers

Hello everyone!

I have a problem in my project.
I'm using the Shield WiFi CC3000 from Adafruit and his librarie Adafruit_CC3000 for connect to WiFi network.
This part is OK, but in the same project I try to control a lamp intensity, and for this a need to use timers, but i think the WiFi connect use timers too, because when the board connect with network, the timers who control the lamp stop to work correctly.

Someone know the priority in the timers or somethink about?

Sorry for my very bad english.

I would suggest posting your code to see how you are using the timers, like are you using Interrupt Service Routines or what?
