General :: Intel 3945abg Wireless Not Working?
Aug 5, 2009
I'm new to linux and I install ubuntu on my wifes laptop since it will hopefully slow down the amount of problems I have to resolve.I ran the live cd of ubuntu and wireless was working all ok, showed my wife around and she was like ok install it.I used the GUI and install ubuntu, and updated (apt-get update) after that the wireless is not working.I see the device, but have no idea whats wrong. Please could someone inform me as to which things to post in order to get it sorted. Since this seems to be the only issue.

What do you think? Wife just bought a new Compaq 610 series laptop. These are the wireless specs:
Code:
10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
30:00.0 Ethernet controller: Marvell Technology Group Ltd. Unknown device 4357 (rev 10)
Strange thing is when I ping the router, I get this, pings one time then dies:
Code:
anna@katie:~$ ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.
In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.
I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

I clicked "Network Settings", and I found that the ip address was wrong, which is "192.168.1.10/24", and netmask field is empty, so I modifed the configuration file located in /etc/sysconfig/network, named ifcfg-wlan0, added one line(NETMASK= '255.255.255.0'), saved it and reboot the system. After rebooting the system, I still found the ip address is wrong and netmask field is empty, so I have to use ifup command to activate my card manually every time the system starts.

I have an IBM Thinkpad T60, running Ubuntu 10.04 (Lucid) with a dual boot of Windows XP. I am having trouble getting it to connect to my home wireless network, which uses WEP. It connected fine at my university when I first installed Lucid, but has not connected at home. I can see the network in the panel applet, with a good signal strength, but when I try to connect it repeatedly asks me for my key and never actually connects. I had this problem shortly before I installed Lucid, though it was working for a long time previously. I'm not sure what update caused it to stop working because I was at my university at the time, and it works fine there even now, so I didn't realize it right away.
I doubt this is a hardware issue because I can connect to the same network when I boot into Windows. I have seen posts about similar problems on the forums, but couldn't find any solutions that helped me.
Below is the information the wireless help guide said to post. Machine Brand and Model: IBM Thinkpad T60
Wireless Brand, Model, and Wireless Chipset: lspci -nn | grep 'Wireless'

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4227] (rev 02)

I am unable to get my intel pro/wireless 3945abg connected to my router. The firmware has been installed and at first was even able to connect, but now the access point doesn't even show up in network manager. I am currently able to connect using a USB wireless adapter, but for certain reasons, would prefer to use the former. I've looked over this page with no results.

It's also because I've never had any big problem. The last openSUSE I used without problems was/is 11.2(I still use it as main desktop because of problems since 11.3).The problem is - the DL speed is repeatedly drops down to around 156KB/s albeit my top speed of router-NIC combination is at 21-22MB/s. When this happen and open network manager and click/reload my wifi or restart wireless or even computer, the speed is back at the top. But after few seconds, minutes it drops down again, and so on. I made some images(to see it on the network manager draphs):after that drop-off:and restart wireless:Best chance to see it is when downloading more files with FreeRapidDownloader or JDownloader. Upload speed is OK. The first time I've seen this problem in 11.3, which i've skipped in hope that 11.4 will be ok and now, as the EOL of 11.2 is coming I'd like to go on.It's also desktop and installation media independent(Gnome works similar, DVD, LiveCD).I've checked many other distributions and none of them had this problem. But openSUSE is my love, so i need and want to solve it

I have my laptop dual booted between Ubuntu 9.10 and Windows 7. In Ubuntu I randomly lose connection to the wireless network. It always works fine when I first boot into Ubuntu but after a while my wireless connection will go down. The signal strength meter will go to zero bars and the black popup message will appear that my wireless connection has disconnected. At first, if I just wait a bit, the connection will come back. However, after about 4 or 5 times of doing this it will then ask me for my password, and inputting the password does not reconnect me to the AP. I am finally forced to reboot. Then it works OK for a while again and the cycle repeats.
It works fine in Windows7 all day, every day. I have the Release Candidate of Windows7 so it's going to expire soon. I would really prefer to make Ubuntu my everyday OS on this laptop rather than pay for a Windows7 license but I cannot tolerate a flaky wireless connection.
I had 8.1 on this laptop at one point and I never had any problems with the wireless then, that I can remember. I had no Ubuntu for a while but then I came back with the 9.1 and was loving it until the wireless problem reared it's ugly head.

My wireless is not working after a fresh install of OpenSUSE 11.2. I cannot connect in KDE or Gnome. I installed cnetworkmanger and I can't get anything to connect. My wired network card on this laptop has been down for a long time. All I have is wireless. I have to roll back today to 11.1 if I can't fix it, but I really have been looking forward to 11.2 for some time. This is really a stupid bug to have in supposedly production ready software. Maybe I should add that in KDE knetworkmanager does not load by itself. I have to load it manually via console every reboot. I get this:
> knetworkmanager
Object::connect: No such signal QTreeWidget::itemDoubleClicked(QTreeWidgetItem*)
Object:: connect: (sender name: 'twNetworks')
It puts the icon in the system tray, and annoyingly hides it, so it took me a while to evern realize it was there. When I point my mouse at it, it says "Networking Information Not Available". When I click it, it says Network Management Disabled. cnetworkmanager spews out a bunch of errors and finishes by saying it can't find any .service files. I configured the device via 'Network Devices' in YaST. Hardware info says it is using the iwl3945 kernel driver. Everything was fine in OpenSUSE 11.1 and 11.0.

I recently installed F10 x86_64 on my Lenovo T61 laptop, and while I'm quite pleased with F10, I am having a difficult time with my wireless card. I spent most of yesterday searching for a solution, but none have presented themselves. Scenario: I am trying to connect to a HIDDEN SSID with NO ENCRYPTION (work Wifi, don't ask) using network-manager and its associated applet.
Symptoms: I left-click on NetworkManager, select "Connect to Hidden Wireless Network", enter my information, NetworkManager does a few things, and finally I'm told that NetworkManager cannot connect to my network.

I have some serious trouble getting the Wireless connection working, using Fedora 13 on a Dell XPS M1710 laptop which has an Intel Pro Wireless 3945 ABG adapter. I have previously tried an earlier version of Fedora I think it was version 10, where it worked flawlessly out of the box, but all versions since then, simply wont work properly. I got the Fedora 12 64 bit working at some stage, after using hours and hours trying to get it working, and suddenly it did. Don't know what suddenly made it work, since I haven't made any new changes, just re-checked the old ones. But I needed to use Skype which is only in 32 bit, so I had to reinstall to a 32 bit version, and then couldn't get it working again.
I can get it to work with any Windows version, no problems. I have also tried with PCBSD version 7.x, 8.0 and today I tried the new 8.1 just to see if that worked to, an no problemos, it works perfectly out of the box, I could set it up in 5 minutes, even though I don't have any previous knowledge of PCBSD, other than a few short trial installs.
It has to be said that I am a newbee to any Unix/Linux, so I don't know how to troubleshoot properly, and have only tried a few things which I have picked up from other forums. But unfortunately nothing seems to work. The first thing I did after a clean install was I looked in the Fedora 13 documentation, that says I should check that the NetworkManager is controling the interface, I tried to start up NetworkManager but nothing happens, no reaction what so ever. I tried rebooting and then restarting NetworkManager, but no matter what I try, I won't work, not even if I am using the root account.
I noticed right after the install, that there was a choice of connecting to a hidden network in the lower right corner of the screen, but while I have been trying to get the NetworkManager to work, it has suddenly disappeared (I have disabled SSID broadcast on my Linksys router. I've tried to run lsmod and it seems like the right firmware is running, I think it was called IWL3945 or something like that. I think there were around 3 such modules running, plus a Dell module.
Another important note, before I even touched the the WIFI, I connected to the Internet via my normal fixed LAN connection, and installed all the updates that were available and rebooted the system. I am using an LinkSys WAG354G V2 ADSL router, where I have disabled SSID broadcast. Is there a kind soul out there, who has a good idea of what the problem is, or a good idea of how to troubleshoot it ? since a laptop without a WIFI connection is not of much use to me.

I've always wanted to learn this branch of computing, and I do think it's rather interesting. So, I was following in unison both this and this, which so far just tell me to download ipwraw-ng and extract it, but when I cd into the folder, and say make, I get this:
Code:
ibo@ibo-laptop:~$ cd Desktop/ipwraw-ng/
ibo@ibo-laptop:~/Desktop/ipwraw-ng$ make
WARNING: $SHELL not set to bash.

Have been using Arch for about one year. Everything works great until a few days ago. My wireless card couldn't connect to my router.
kernel: 2.6.32-ARCH
wireless card: Intel 3945ABG
wireless card driver/firmware: iwlwifi-3945-ucode 15.32.2.9-2
[code]....
The wireless card:
Code:
#lspci -vv
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Subsystem: Intel Corporation Device 1010
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+
[code]....
Since the card works in scanning mode, I assume it's OK. I have other devices in the house that also connect to the same AP. Everyone works except this laptop.

I've just installed F12 64bit on my notebook. Everything works great. Only problem I'm having at the mo is my WLAN is slow at DNS resolution. On wired it works fine. I know it's not my access point as it is part if my router and I've rebooted it a few times. My other wireless notebook (Windows 7, Intel 3945ABG) doesn't have the same issue, and this notebook didn't when on Windows 7. I'm using OpenDNS as my forwarders.When I open a URL in Firefox (3.5.5) it opens the site immediately on wired. On wireless it will sit for 3-4 seconds before opening the site saying looking up .................. Once on the site browsing behaves normally.Anyone else having similar issues?

I am running openSUSE 11.3 updated with all the latest patches and I cannot connect to my wireless router. I am running Linux Mint 10 on the same type of notebook HP Compaq 6910p and it worked right after the install. If I take off the security WPA & WPA2 Personal I can connect. lspci -v | less shows this for my wireless card.
10:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
Subsystem: Intel Corporation Device 1000
Flags: bus master, fast devsel, latency 0, IRQ 29
Memory at e4000000 (64-bit, non-prefetchable) [size=8K]
[code]....
I am using the same settings for both notebooks just can't figure out why openSUSE 11.3 won't connect. I get the prompt to key in my password, I've even checked the box to show password to make sure I was keying it in correctly. Everything was good but it just goes right back to the password prompt after it fails trying to connect.

I followed the sticky about setting up wireless and I have come to an issue where the WLAN switch which is on this computer can be pressed, the light comes on, but no WLAN. When I looked in dmesg, this is what I get:
ipw2100: Detected Intel PRO/Wireless 2100 Network Connection
firmware: requesting ipw2100-1.3.fw
eth0: Radio is disabled by RF switch.
When running iwconfig wlan0 heres what I get:
home/j-dub # iwconfig eth0
wlan0 unassociated ESSID off/any Nickname:"ipw2100"
Mode:Managed Channel=0 Access Point: Not-Associated
[code]....
Notice it says that the 'Radio is disabled by switch' in dmesg. I can press that switch until the end of the world comes and it does absolutely nothing but make the WLAN light put on a light show. And it shows the wlan to be unassociated with any clients. So, what are my options to get this Wireless up and working?
Computer/OS info:
Fujitsu-Siemens Amilo M7400

The wireless on my 64-bit openSUSE-11.2 installed on my Dell Studio 1537 laptop stopped working some time back (possibly more than a one or two months back). I just discovered this last week when on business. I have not used the wireless under openSUSE-11.2 for a while so I am not certain what broke it, but I am suspicious of an update. I note openSUSE-11.3 milestone-7 works great with the wireless (on a liveCD). I note possibly two related threads, although I note no failed request for firmware in my case:request for firmware file 'iwlwifi-5000-2.ucode' failed [INTEL 5300 AGN] [OPENSUSE 11.2] - openSUSE Forums, and I see another thread here: Suddenly No Wireless Network Card - openSUSE Forums... but I can not tell if what I have is the same problem, so I did not add to those threads. In my case I can scan for the network, and see the SSID. An ip address is assigned. But a ping does not work.
Some details, the wireless is:
Code:
04:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235]
Subsystem: Intel Corporation Device [8086:1121]
Kernel driver in use: iwlagn
In terms of installed apps:
Code:
rpm -qa '*wireless*'
wireless-tools-30.pre8-5.1.x86_64
wireless-regdb-2009.09.08-2.2.noarch
[code]....
I know the router wireless network is good, because I can connect to the router via wireless with another laptop (old Fujitsu-Siemens Amilo 7400M with older Intel wireless), and the router wireless also works with this Dell Studio 1537 PC (with same hardware) but with openSUSE-11.3 milestone7 version.

I have an Intel 3945ABG WiFi card in my Laptop (Dell Inspiron 6400). The problem is that I'm not able to get my card detect the Wireless Network. I'll list the prolem more specifially below. O.S. Fedora 12 x86-64
1. The Network Icon on the Taskbar (is it what it is called here in Linux??) shows Wireless is Disabled under the Wireless Networks. Wired Net works fine.
2. If I goto System->Pref->Network Connection the Network Tab is empty.
3.Under System->Admin->Network Config I can see two Devices; one is eth0 (active) with a checked check box. Second is wlan0 which is Inactive and has a checked Checkbox. The Activate and Deactivate buttons are disabled for both these. If I go and see in the Properties of the wlan0 it says controlled by Network Manager checked but the Network Manager comes up empty.
4. This forces me to remove that "controlled by network manager box" which enables the activate and deactivate buttons. Now I can Activate my wlan0 adapter and the light on the Laptop for WiFi starts up. During startup (activation I get this error in the pop-up box:
Error for wireless request "Set Mode" (8B06):SET failed on device wlan0 ; Invalid argument.). But the popup eventually closes auto. The Network Config box now shows it active but the Taskbar Icon still shows Wireless is disabled. And still the Network Connections has an empty box under Wireless tab. I donno what to do next. The card worked fine with Ubunto 9.04, openSuSE 11.2 (both 32 bit btw) and Fedora 11 again 32 bit.

I'm running Ubuntu 9.10 on a Gateway M520 laptop, and after failing to get the Broadcom wireless chip that came with it working I swapped it out for an Intel PRO/Wireless 2200BG. Unfortunately, I haven't been able to get wireless to work. The chip doesn't appear to be turned on (it is detected though), and the hotkey to switch wireless on/off (Fn+F2) doesn't work in Ubuntu. I also am not sure if I have the proper drivers to get the chip working with Ubuntu, and I'm not sure how to figure that out.
Since I've noticed it's asked for a lot, here's the output for iwconfig:
lo no wireless extensions.
eth0 no wireless extensions.
eth2 radio off ESSID:off/any
Mode:Managed Channel:0 Access Point: Not-Associated
