    Atheros wireless usb adapter(Sorry for trying again )

    I can't post messages, I think something is wring with my internet.

    Anyway, I'm gonna copy paste what I've been trying to say...

    Hi guys, I just bought the TP-LINK Model No. TL-WN821N. It's an atheros. And I was wondering where can I find the drivers for Linux. It only includes drivers for Windows.

    I don't have much experience with networks, but I would appreciate your help guys


    I found this website, if someone think I'm looking at the wrong website let me know.

    http://en.gentoo-wiki.com/wiki/TL-WN821N#Introduction

    I got stuck in the patch section, I don't know what they are trying to say.

    They are using

    diff -urp compat-wireless-2009-02-22_AR9170_230209/drivers/net/b44.c compat-wireless-2009-02-22_AR9170_230209/drivers/net/b44.c

    They are comparing the same file, there is some code they are showing but I don't know what they want me to do.

    Please help

    The page you link to looks rather outdated since it refers to kernel 2.6.30 (maverick is on .35) and tbh you're not going to have much luck following a gentoo howto on ubuntu. Gentoo is compiled from source whereas ubuntu provides precompiled packages which is less work for you but makes most gentoo howto's almost entirely useless for us.
    I take it you've tried just plugging the adapter into your computer? You might be supprised how many drivers are included by default.

    If not you can try installing some updated drivers using then linux-backports-modules-wireless-maverick-generic package.

    btw. the forums seem to be a little overloaded these past few days which may be why you're having trouble posting.

    Well, if I have one chip already working on my laptop, how can I know if it works or not. It did came with a CD, but it only contains drivers for Windows7,Vista, XP, and 2000. But not for linux.

    Re: Atheros wireless usb adapter(Sorry for trying again )

    If if works clicking on the network manager applet in the panel will show two lists of available wireless networks (one from the internal chip and one from the usb adapter).

    In my previous post I wasn't refering any drivers on the cd the adapter came with, I was refering to drivers installed by default.

    If the adapter doesn't work straight away try clicking the package name link in my previous post to install and package which provides updated wireless drivers (its an official package from the official repos btw.)

    I installed it, but I clicked on the panel where all the routers are displayed and it only shows one list. So, I guessed it did not work

    In that case could you open a terminal and copy and past here the output from;
    Code:
    dmesg|tail
    lsusb
    immediately after you've plugged the adapter in.

    I think all you need to do is run the hardware drivers / restricted drivers manager from the system menu and activate any wireless driver you see (which tbh I should've thought of several posts ago).

    I'm attaching some screenshots. I do want to mention that the chipset my laptop has is a Broadcom. These are the two options drivers manager gives me

    Hmm seems to be no firmware package for it right now. . .
    Try downloading http://git.kernel.org/?p=linux/kerne...1_1.fw;hb=HEAD (save as ar7010_1_1.fw) and copying it into /lib/firmware rebooting and then reinserting the adapter.
