Debian Configuration :: Wlan0 Troubleshooting Using Iwlwifi For Intel 5100?
Oct 1, 2010
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:
wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
from lspci:

I have recently installed the intel-wireless-tools and now my laptop detects my wireless router and connects to it but when I go into a browser I can access the internet. If I connect to the wired network no problems(same router) no go on Wireless.

I'm a new Debian user but I've been around Linux for awhile. I wanted to try Debian because I wanted something stable and that I could set up myself from a minimal install. However, I'm having issues with my WiFi connection. I'm running KDE and connected to the network, but I can't access any webpages or ping, for example, google.com. I know the network is working because I'm connected to it on my phone and my wife's Macbook. Here's the output of lspci:

I installed linux-image-4.1.0-trunk, when I boot into the kernel there's no wireless available. Dmesg indicates seems like the firmware is loaded, although firmware-iwlwifi is installed:
...

Have been using Ubuntu Desktop Amd64 for 6months, on a dual boot alongside Vista64. Since first installing the OS, I have switched over to Ubuntu & use Windows only for heavy multimedia edition & the occasional gaming.I just bought a netbook and installed Ubuntu 10.04 LTS NBR. Works great, except for wlan. No propriety drivers available for my Intel Wifi Link 1000BGN.
I've spent hours trying to install iwlwifi, but the process is somewhat complicted for a noob such as myself.After much reading and trying, I've managed to download and install iwlwifi-1000-ucode-128.50.3.1.tgz, (following the http://intellinuxwireless.org/?p=iwl...=howto-iwlwifi instructions)and am now working on installing the mac80211 subsystem (following the http://intellinuxwireless.org/?p=mac...howto-mac80211 instructions)When running

I want to build a custom system and I need your opinions. I have an old laptop which I want to configure as a system for troubleshooting purpose, my idea is to have multi-boot system with multiple root file systems, e.g. one root file system has only BIND to work as DNS server, another root file system has only Samba, etc., and I can choose which system to boot into from grub, or a custom menu after booting grub.
I thought of setting multiple partitions and install a full system on each one, but I thought that there might be a better way to do this, I'd like to hear your opinions.

My Lenovo laptop has an Intel Pro 4965 Wifi adapter,here is the "lspci" detection:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
So installed the needed "firmware-iwlwifi" kernel module, which is a correct kernel module for this adapter.
Then "modprobe -a iwlwifi"........no complaints !
However,
#iwconfig wlan0
wlan0 No such device
and
# lsmod |grep iwlwifi

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).
[code]...
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?

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?

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).

during advance graphical debian squeeze installation, it displays the following message Detect network hardware Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as a USB stick or floppy.
The missing firmware are: iwlwifi-5000-5.ucode iwlwifi-5000-4.ucode iwlwifi-5000-3.ucode iwlwifi-5000-2.ucode iwlwifi-5000-1.ucode If you have such media available now, insert it, and continue.

how to set up wireless networks. The technical language is foreign to me. My notebook maybe described as follows:
Make and Model: SONY VAIO FW490
Processor: Intel� Core™ 2 Duo Processor P8700 (2.53GHz)
RAM: 4GB DDR2-SDRAM
Graphics card: ATI Mobility Radeonâ„¢ HD4650 graphics card with 512MB vRAM.
[code]....
It came pre-installed with Windows Vista Home Premium but now I have Fedora 11 (w/ Gnome) as the only OS. The router that I am using with an Ethernet cable connected to my laptop is a Netgear 54Mbps Wireless Router WGR614 v7 connected to a Motorola Surfboard Cable Modem. Both worked right out of the box and now I have wired Internet access. RCN is my ISP. I would like to avoid using the Ethernet cable connecting my laptop to the router.
This is what I have done so far:
1. Gone to System>Administration>Network
2. Clicked "New" then chose "Wireless connection" from the list
3. Chose Intel Corp. Wireless WiFi Link 5100 (wlan0) from list. The other option was "Other Wireless Card".
I don't know what to do after this. What should I choose in the windows entitled "Configure Wireless Connection" and "Configure Network Settings" ? I chose Ad-Hoc for mode and entered an SSID name even though I have no explanation for taking these actions. As for the other settings, I simply went with whatever was already selected. At the moment, I lose Internet access when I disconnect the Ethernet cable. I see other wireless networks when I click the network icon on the top right corner of the screen. I don't know how to make my router appear on that list if that's necessary.

In simple, I have tried everything I can find on this issue, but I am still unable to get it working on my HP DV4 laptop. My laptop has a Intel 5100 wireless card, and it always says that wireless is disabled. Ive tried booting with the wireless switch off, with it on, ive reinstalled the driver and did everything in a post I found here (cant find a link) that basicly had me reinstall the driver from intels site, then reload the network manager, to no prevail. Im running ubuntu 10.4.1 (just installed), and this is really a big issue 4 me.

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
[code]....
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'm trying to get my Dell Latitude work with wifi speed >54Mbit/s, and up to now without any success. The router is a Dlink DIR-635, it has 'n' enabled and working (got an apple laptop connecting at 130Mbit/s, can't test the actual throughput though, since it's the only high-speed device).
Here's the device data:
0c:00.0 Network controller: Intel Corporation WiFi Link 5100
Subsystem: Intel Corporation WiFi Link 5100 AGN
Flags: bus master, fast devsel, latency 0, IRQ 43
Memory at f1ffe000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
[Code]...
I'm running 11.4, added the compat-wireless recently to be able to run the newes firmware (iwlwifi-5000-5.ucode , firmware version 8.83.5.1 build 33692), but still all I get is 54Mbit/s. I'd like to know if ANYONE ever got the 802.11n speed on linux, and in particular with these intel cards.

I have seen tons of threads on the internet about Ubuntu 10.04 having wireless issues but none of them have lead to me fixing the problem so I decided to come here. I have been able to connect to access points before but sometimes I have to reboot or reboot twice just to be able to see the wireless points and the enable wireless is always greyed out. And if I am connected to an AP or hardwire the connection drops frequently.

I just did a dual boot with OpenSuSE 11.2 and Windows 7. They both work perfect but for some reason the wireless (intel wifi 5100 AGN) and my wired network card (Atheros AR8131 Gigabyte controller)do not work in opensuse. Now the problem is that I do not have a clue about linux and therefore I don't know how to fix the problem. I searched the forum and I tried these commands "sudo /sbin/ifdown eth0" and "sudo /sbin/ifup wlan0" and both says something like device not connected/present (can't remeber exactly).

I moved to Berlin recently and I got wireless internet through an access point. I'm supposed to use the laptop's built-in wireless netcard to access the internet. This usually works in windows (connection falls out from time to time), but I have yet to make it work in linux. I'm using OpenSuse 11.3 64-bit and the Knetwork manager. Most of the settings in the network manager are correct, but it keeps wanting to use system certificates for the server. By that I mean it keeps checking 'Use CA System certificates'.
So I can't choose the CA-certificate supplied by my internet provider. I keep removing the check-mark and pointing it to the 'hotzoneCA.der' certificate. I also got a 'personal' certificate, in lack of a better word. Its called 'jacob_collstrup.p12'. The Knetwork manager seems to accept the 'jacob_collstrup.p12' certificate, but not the other one.
I just put the certificates in a folder like this /jacob/home/hotzone/zertifikate/ I can see the network fine using the Knetwork manager, and the signal strength seems ok. Not too good, but it shouldn't be a problem. I might have messed up the system, since I first tried this guide, prior to experimenting with Knetwork Manager:
1. (had to run this one as su)
Code:
wpa_supplicant -w -i wlan0 -c /etc/wpa_supplicant.conf -Dndiswrapper -dd �t
2. (This was supposed to be put in a wpa_supplicant.conf file)
Code:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
opensc_engine_path=/usr/lib/opensc/engine_opensc.so
pkcs11_engine_path=/usr/lib/opensc/engine_pkcs11.so

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
When I boot in Windows, wifi works fine.

I have a Dell Latitude E6500 running Opensuse 11.3. As far as I can tell the module for my wireless card is loaded correctly and it's working:
Code:
sudo lspci | grep -i wifi
0c:00.0 Network controller: Intel Corporation WiFi Link 5100
Code:
[ 556.642557] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:d
[ 556.642560] iwlagn: Copyright(c) 2003-2010 Intel Corporation
[Code].....
The funny thing is that it works fine in a Fedora installation, which has an older kernel and older drivers, on the same laptop. The fact that the indicator light doesn't come in when the physical switch is turned on suggests it's something to do with that switch.
