Thank you for opening this bug and helping make Ubuntu better.
Unfortunately, you did not provide enough information for us to be able to determine what happens.
At a minimum, we need:
* Ubuntu version
* a more precise description of what you are trying to do: "the antenna does not activate when starting nor when driving the switch" does not help: I do not know which antenna, what is it you mean by 'activate the switch' and, in fact, which switch is this.
Right now this sounds more like a support request than a bug.
Thanks to try to help me, I am usuary useless level and one crowds to me.
I have a HP-Compaq-6735s, with processor AMD Sempron SI-40.
The antenna is a 4312 Broadcom BCM 802.11b/g LP-PHY.
The installed version is Ubuntu 11.04
Before the last update the antenna worked with privative controller, but after updating and reinitiating the antenna does not ignite and in the controllers it does not appear to me nor like option.
I believe that with the actulización one has changed to 64 bits, because I cannot either see videos, requests me that it updates pluguin of adobe flash and when going to the update is the one of 64 bits.
I am going to see if with himself install the version to me of 32 bits and to see again that it happens.
This is not a docs problem, removing ubuntu-docs from affected packages.
