Ubuntu Networking :: Source Code For CB21AG Wireless Card?
Jul 3, 2011
Two Questions:
A: Can you tell me which code belongs to CB21AG code? In the directory debian/debian/drivers/net/wireless/ath/ath5k/ I can see two modules written
1. pci.c and
2. ahb.c
Not sure which one to look for!!
B: If I want to build ath5k.ko module by making some changes then how to build it? If I go to directory debian/debian/drivers/net/wireless/ath/ath5k/ and give make then it doesnt goes through sudipto@sudipto-ThinkPad-T61p:~/kernel_workspace/Development/source/debian/debian/drivers/net/wireless/ath/ath5k$ make make: *** No targets. Stop. sudipto@sudipto-ThinkPad-T61p:~/kernel_workspace/Development/source/debian/debian/drivers/net/wireless/ath/ath5k

I'm setting up my first Linux laptop with Ubuntu 11.04 and my CB21ag wireless card works, but won't achieve speeds over 11Mbps (maybe not "doing 802.11g rates for some reason?) I guess this cardbus card is manufactured by Atheros for Cisco so I maybe that's why I'm seeing two wireless connections - the one with the "airo" driver gives me 11mbps, the other with the ATH driver would only get me 1mbps so I deleted that. The card seems to disconnect/reconnect periodically too - messages pop up frmo the wireless icon ...
lsmod says "airo" and "ath5k" are loaded
So to get 54Mbps (802.11g speed) I'm wondering if theres maybe a different driver module for the CB21ag card or some configuration I need to tweak. More info - security is static WEP, lshw -C network returns some "wierdness" about network 0 ?
-laptop:~$ lshw -C network

Does anyone have a driver for Cisco Aironet PCMCIA AIR-CB21AG-A-K9 wireless adapter that works with Ubuntu 11.04? Ubuntu does not see the card when plugged into the PCMCIA slot. I thought that if Ubuntu had a driver installed, it would pick up the device.

I intend to attach WLAN PCMCIA card to my embedded system to connect to a wireless network. However, my embedded system uses a strangs OS that not supports the card driver. I think that I can investigate on how Ubuntu control the card to find out the way to control it in my system. The WLAN PCMCIA card that I can buy is:TP-Link TL-WN510G,Linksys WPC54GSCan any one tell me, how can I have the source code of WLAN PCMCIA driver and how can I find out the way Ubuntu control this card?

Has somebody used DAFS (Direct Access File System)?I've found a lot of literature about this file system,where the comprassion tests promise a ~20-50% faster packet transmission,than in the strandard NFS.But I can't install DAFS,because the source code is for old kernels 2.4.Does anyone know,why did the research of this file system stopped in 2003 year,and there are no newer versions?

I read that xinetd listens on the service port and passes incoming traffic to the service (ftpd) via stdin. However, the ftpd source code reads its input from a socket not from stdin.
Am I to conclude that in order to be managed by xinetd, the source code for ftpd (or telnetd etc..) must be modified or recompiled to take its input from stdin??

I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.

Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.

I have lenovo thinkpad, T61 with Intel 4965AGN wireless card. It is a N card, it works under N mode in windwos, but not in Ubuntu (10.10). I installed ndiswrapper and got the windows xp drivers for this card. the issue is that i got an error when installing the drivers and since then I cannot use wireless.
The error i got is: Code: Module could not be loaded. Error was: FATAL: Could not read '/lib/modules/2.6.35-24-generic/kernel/ubuntu/ndiswrapper/ndiswrapper.ko': No such file or director I unistalled the driver, but now under network connections no wireless connections appear, nothing. I cannot use wirless anymore.

wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.

I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.

My wireless was working fine for about a year using 9.10 until I installed an update about May 28 2010. After that my HP laptop did not recognize any wireless routers including my Netgear. In early June I upgraded to 10.04. My HP laptop has: product: AR5001 Wireless Network Adapter vendor: Atheros Communications Inc. Dose the following apply when looking for the source of my disabled wireless found at: [URL]
Setting wireless regulatory domain via module option no longer supported. Ubuntu 10.04 LTS enables the CRDA wireless regulatory framework for controlling which wireless channels are usable and visible in a particular location. If you previously had to use the module option similar to that below in /etc/modprobe.d/options.conf to allow access to certain channels in your locality then you may find that wireless will not function at all: options cfg80211 ieee80211_regdom=EU You should remove this kernel module option on upgrade from releases earlier than Ubuntu 9.04 and use the iw*reg command instead. (This change was made in Ubuntu 9.04.) Here are the results for the Code sudo lshw -C network

I downloaded wine from a windows laptop, but because you have to have a computer running Linux to download it as a .deb package, I had to download the source code as a tar. bz2.
Does anyone know how I compile it and make it executable?

I was trying to install VPN client for my Ubuntu 9.10 64-bit. During the installation process the terminal reads:
"Directory containing linux kernel source code [/lib/modules/2.6.31-21-generic/build]"
On that I pressed enter for the default option (in bold). After a few more steps I reached the following error:
Making module
sh: Can't open ./driver_build.sh
Failed to make module "cisco_ipsec.ko".
[/lib/modules/2.6.31-21-generic/build] is the location where the installer expects the kernel source to be (I am guessing). So unless I correct the terminal (by providing the location of the kernel source), I think I will keep on getting the same error message.
So to get the kernel source I visited: [URL]From there I copy pasted the command:
sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
apt-get source linux-image-$(uname -r)
Everything went fine, but even now I don't know if at all I have a kernel source and where it exists on my machine.
