Debian Configuration :: Wlan0 Absent - Card Definitely Working

Jul 7, 2010

I'm having problems getting my wireless network working. The same problem exists in both Debian 5.04 and Ubuntu 8.04. I'm using a Sonet ZEW2500P USB wireless card, which shows up when I look at lsusb. The card works under Windows, so its not a hardware problem.

When I run iwconfig, wlan0 simply doesn't show up on the list. It doesn't go by any other name either. I've tried adding iface wlan0 inet dhcp auto wlan0 to my /etc/network/interfaces file, but to no effect. I've tried using both the rt2000usb driver and the old rt2570 driver, and made sure both are not loaded at the same time using lsmod, but this doesn't help.

I wanted to try the CONFIG_NET_RADIO enable/rebuild kernel technique, but I can't find CONFIG_NET_RADIO anywhere in my autoconf.h file!

I assume someone will want to see a log file of some kind - just let me know which one (and where I can find it).

Fedora Networking :: Bring Up Wi-fi PCI Card (ifup Wlan0 Or Ifconfig Wlan0 Up) Whole PC Just Hangs Until Power It Off

May 20, 2009

When I try to bring up my wi-fi PCI card (ifup wlan0 or ifconfig wlan0 up) my whole PC just hangs until I power it off.

I believe I have the right drivers, but cannot see what I am doing wrong.

I'd really prefer not to go down the ndiswrapper route.

Firstly, I can see the PCI card and the driver it is using :

[J@gx260-f10 ~]$ lspci -k
01:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller (rev 20)


the PC just hangs for ever. No mouse movement, ctrl-alt-del, nothing.

I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.

Debian Configuration :: /etc/network/interfaces: Ra0 Or Wlan0?

Mar 30, 2010

I had one of those random system deaths, so reinstalled squeeze (daily netinst image I think...) on my eee 1000, which uses an rt2860 wireless chip. The new install only installed 2.6.32, which I had been avoiding using because of a few problems, including it dealing with networking slightly differently. I couldn't get it to work - even without encryption - using wicd. Having had a read of [URL]... , I had a look at /etc/network/interfaces, which read; This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).


ra0 is now called wlan0, as far as I'm aware. I've read in several places that it is best to expunge this file of all references to wifi, so I removed the bottom section (after '# The primary network interface'). I still got nothing. However, if I go ahead and change the 'ra0's to 'wlan0's, it seems to work - wicd connects. Not very familiar with Debian (spent more time on SUSE. Drop your tomatoes - I like it. Any idea what is happening? Is what I'm doing wrong? Conversely, is the file wrong? Should it be reported? Against which package? Including any particular files?

Debian Configuration :: Wlan0 Gets Deactivated While Login

May 13, 2010

From yesterday on, I am not able to connect my Laptop to my WiFi Router automatically when logging in to gnome desktop.

The following is the message found in /var/log/messages.

Its Lenny 5.0.4 and I can see my wifi LED ON till the gdm login page. After the login, while loading my desktop, the LED goes OFF and I have to restart the network-manager for enabling the wifi again. Why is this happening? Do I have to change the configuration settings in /etc/dbus-1/system.d/ to fix this. I really don't know what change needs to be done there and where.

The same day when this problem started while logging in I got an error message from nautilus. The screen-shot is attached with this mail. Does this error have anything to do with the network issue?

Debian Configuration :: Creating A Network Bridge From Eth0 To Wlan0

Jan 18, 2016

I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.

Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:

(The WiFi is secured with WPA2 Enterprise)

Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d


The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?

I've installed firmware-iwlwifi I've modprobe -r'd and modprobed the iwlagn module I CAN scan, using iwlist wlan0 scanning, and I can see my essid, hovering in the distance. it is definitely broadcasting.

I use wicd and wicd-curses. No wireless show up in wicd-curses. ifup wlan0 gives me no dhcp offers received and slumbers again. from iwconfig:

Ubuntu :: Wireless Card Named Eth3 Instead Of WLAN0

Mar 17, 2010

I have managed to get everything MOST of the way setup...Come to find out though that I cant get conky to function 100% due to my wireless card being named eth3 instead of wlan0...I can get everything to work except for the signal strength, since ubuntu thinks its an ethernet cared. (although it show up as wireless connection in the network interface on the top right of ubuntu control bar). It's not a BIG deal but I was wondering if anyone had a fix or work around for this. BTW it is a Broad 4311 using Broad STA drivers if that makes any difference at all...

Ubuntu :: Wireless Card Won't Stay Connected - Iwconfig Says Wlan0 Is Interface

Jun 11, 2010

having trouble with my asus 1000 rt2860 wireless n card and WPA/PSK/WPA2 connections. Funky thing is it worked in the 2.26.32-21 kernel (iwconfig shows ra0 as the wireless interface), but when the kernel was updated and pushed through in the ubuntu updates to 2.26.32-22 the wireless card won't stay connected and iwconfig says wlan0 is the interface. I checked the proprietary drivers and they said that the driver for my card was active, but not in use. How do I use the ra0 instead of wlan0?

how do i use the driver that's listed as not being used? I'm having to boot up lucid with the older kernel now, it's annoying, lots of programs aren't running as expected as a result. I've tried manually installing the driver from the RaLink website as detailed in many other posts concerning this wireless card. It seems to work for some people, but not with me.

Debian Configuration :: Change Gfx Card

Sep 20, 2015

I have debian latest stable and have been using a geforce gfx card which has now failed.I have removed the gfx card and activated the on board gfx in bios and I can boot to the grub screen.The onboard gfx is on my i5 4600.After I select debian from grub I end up with a blank black screen and a small cursor in top left hand corner but I cannot type anything with this cursor. From this screen I can only ctrl+alt+del for reboot or physically turn off the pc.I think this is a driver issue but wouldnt debian just use a default gfx driver automatically in this situation so I would at least get to a console or desktop? If this is the case what is the process to enable the required driver? via rescue disk?Mobo is gigabyte GA z87 hd3 and im wondering if this might be something to do with uefi or similar?

Debian Configuration :: How To Get Wireless Card To Work

Jan 21, 2010

I'm having trouble getting my wireless card (RNX-G300LX, from Rosewill) working with my Debian install. I had it working at one point in time, but (apparently) something has gone wrong, as it no longer connects. The network I'm trying to connect to uses WPA2. When I try to start up my wireless card as follows:
# ifup wlan0

I get the following response:
wmaster0: unknown hardware address type 801
wmaster0: unkown hardware address type 801

auto wlan0
and /etc/wpa_supplicant.conf looks like this:
proto=WPA2 }

I should also note that running wpa_cli -i wlan0 tells me that it is "trying to associate" with my router, but authentication times out each time.

Debian Configuration :: Wireless Card Name Changed After Reinstall

Jul 10, 2015

I use Debian Stretch and I've installed it twice with the same ISO on the same laptop. First just to test a few things, then freshly installed it again.

The first time the wireless card was named wlan0 (as always for me, I've never had another name), the second time though it was suddenly named wlp3s0.

How did this occur and may I change it back to wlan0?

Debian Configuration :: Wrong Name For The Wireless Card On Reboot

Feb 17, 2016

A couple of days ago I asked why my pc changes the wireless card name.It switches between AR9285 ( right) and AR5008 ( wrong). Well, it is not the case. When system identified with AR9285,it loads ath9k and I can connect to the router. When system identifies my card as AR5008, no kernel module is present at all ( lspci -k). The wrong card name occurs only when system rebooted. If I gracefully shut down the system, it always comes up with a right name for the card( AR9285). So, how to force the system identify my card right no matter if I reboot or shut down?

Debian Configuration :: Transfer Existing System To CF Card?

Apr 18, 2010

I have a lenny system up and running, my CF-card reader is supported and I can mount a 1GB card. My PC _can_ boot from CF cards, I verified... My Linux resides in sda3 (other partition is XP). How would I transfer the partition to a cf card? I tried using dd if=/dev/sda3 of=/dev/sdb1, but as that doesnt work I have the feeling there's more to do... Maybe install GRUB on the CF-Card? Change some paths after copying?

Debian Configuration :: Install The Driver For Mi Wireless Card?

Apr 22, 2010

I'm trying to install the driver for mi wireless card. The instructions say that to build the tar.gz file, I have to:

# mkdir hybrid_wl
# cd hybrid_wl
# tar <path>/hybrid-portsrc.tarhybrid-portsrc-x86_64.tar.gz

The third step i don't understand. I want the folder of the driver to be located in a folder inside home called "Programas" so what I did was to open the terminal, went su, and then did cd Programas. Then I followed instructions 1 and 2, but I don't know what to put where it says <path>.

Debian Configuration :: Connect To Internet Through Wireless Card?

Jun 9, 2010

I am currently trying to connect to internet through my wireless card, after half day's effort I reached to this point:

/******The following error appears in the dmesg kernel ring buffer output:

ipw2200: Unable to load firmware: -2
ipw2200: failed to register network device
ipw2200: probe of 0000:02:03.0 failed with error -5*********/

I found a solution from Intel website saying that the problem might be: "firmware in wrong location or wrong firmware version". So I proceeded to download the firmware and placed it in /lib/firmware. Also I tried to use menuconfig to enable loading firmware via hot-plug, but I think I have done something wrong when I was configuring the hotplug and firmware.

Debian Configuration :: Can't Unmute HDA Intel Sound Card?

Aug 3, 2010

According to HDA Analyzer, my sound card is muted; however, I can't unmute it through HDA Analyzer or anything else. According to alsamixer, everything is unmuted, though. According to the ALSA documentation, there's no 'model' id for my codec -- Conexant 5069 -- so I don't have an option to put in /etc/modprobe.d/sound.conf. What can I do to unmute the card???

Here's the hardware: cat /proc/asound/cards:

Debian Configuration :: No Wireless In Squeeze With Broadcom Card

Oct 30, 2010

I just installed fresh Squeeze to my new hpmini 210-1100 netbook. No wireless. I have checked and I have Network Manager installed already.

I also compiled and installed Broadcom driver from here[url]

I followed their instructions and compiled the driver. I did get a wl.ko driver and installed it insmod wl.ko after modprobe lib80211

I noticed after rebooting neither wl.ko nor lib80211 showed when i did lsmod. So I did modprobe and insmod again. Still no wireless. Here are output of some commands that I thought would be relevant.


I see only 2 computer icon in the system tray but not the parallel bars. When I went to System>Administration>Network, I was not able to add my wireless network name. The Add button was grayed out.

Debian Configuration :: Upgraded 7.8 Aetheros AR9565 WiFi Card And No RDP

Apr 25, 2015

Because of workers here in my company I need a very secure operating system for laptops so I have chosen Debian 7.8. The laptop is Acer Aspire E11 (E3-112-C4NE). This laptop has a built-in wifi card Aetheros AR9565 :

lspci -nn
02:00.0 Network controller [0280]: Atheros Communications Inc. AR9565 Wireless Network Adapter [168c:0036] (rev 01)

Basically the stable 7.8 distribution cannot handle this wifi card, so I read on forums that I should upgrade my operating system. So I did as I read on the forum:

nano /etc/apt/sources.list
deb wheezy-backports main contrib non-free
apt-get update
apt-get -t wheezy-backports install firmware-atheros
apt-get -t wheezy-backports install linux-image-amd64

After this the oprating system recognized the wifi card and loaded the "ath9k" driver. In the Grub the default operating system became :

Linux 3.16.0-0.bpo.4-686-pae

Because I want to restric the workers to access anything else except the designed inner network, I have uninstalled the Network Manager and set the network interfaces in the "/etc/network/interfaces" file as shown below:


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface

auto lo
iface lo inet loopback

[Code] ....

This works, when the operating system boots, it automatically connects to my hidden SSID wiofi network. I can ping other computers on the same IP subnet (

This computer should connect to an XP running under virtualbox, having the IP address of But it does not. On another laptop, running Ubuntu 14.05, having the same network configuration, ( connects to the same XP under virtualbox with no problem....

For Ubuntu nothing is required to be installed on virtualbox, no extension pack, no guest addition, nothing. When I want to connect to XP via rdp, it asks for username and password and after that only a blue or black blank screen and nothing else... Even on the XP I see no sign of any activity that somebody would like to connect.

Checking the network traffic (tcpdump, nast) I see that the two computers are communicating but after a while the communication stops. The rdp XP its in another IP subnet, but Ubuntu can connect without any problem, Debian not...
