EDIMAX EW7811un installation

[praseodym]

Did you unplug the stick and create a new wireless connection? Check:

dmesg | grep b43
lsmod
iwconfig
rfkill list

Obviously, some firmware file missing. Install the package "linux-firmware-nonfree" and try again

[rhyssarge]

how do i do this?? Is there a command that I need to write? thanks again for all this help man

[praseodym]

Either via Software-Center or via terminal

sudo apt-get install linux-firmware-nonfree

[mikewhatever]

I am pretty sure that EDIMAX EW7811un has nothing to do with Broadcom 4312. The former is a USB wireless adapter, while the latter is an internal wireless card.
You can get both working: Edimax, Broadcom.

[praseodym]

I know that

The Realtek driver can be updated later. I was wondering about the module b43 showing up...

I have done this, now what?

Ah, ok, thought I'd mention.
b43 shows up because the OP installed firmware-b43-lpphy-installer, probably without internet access, so there is no firmware.

im not gonna lie Mikewhatever, i have no idea what any of this means :\ im at the learning stages. Any help from both of you would be greatly appreciated.

cheers,
