Ubuntu Networking :: System Hang When Using Intel Pro/Wireless 2915ABG On 10.10

Dec 16, 2010

My system hangs within a few minutes after I turn on the Intel Pro/Wireless 2915ABG interface built into my motherboard or if I boot with the interface turned on. I have been having this problem for a couple of years and tried to fix it myself from time to time. (I think that I even asked for help in the Forum once.) The wireless interface used to work fine with Ubuntu and I kept hoping that the problem would "magically" disappear with each upgrade. I also read about the recent problems with ndiswrapper and similar interfaces. But this doesn't seem to be my problem. The entries in /var/log/messages just prior to the last hang were

Dec 15 09:09:47 periwinkle rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="824" x-info="http://www.rsyslog.com"] rsyslogd was HUPed, type 'lightweight'.
Dec 15 09:09:47 periwinkle rsyslogd: [origin software="rsyslogd" swVersion="4.2.0"

[code]....

I don't know what process gdb was trying to trace. Since I was testing the system, I was only running Firefox, which has always triggered the problem. The output from "dmesg | grep -e ndis -e ipw" was

[ 19.121563] libipw: 802.11 data/management/control stack, git-1.1.13
[ 19.121566] libipw: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com>
[ 19.161180] ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq

[code]....

In previous version of Ubuntu, the messages just before the hang used to complain about the firmware in the interface being buggy. I intended to send the output from iwconfig and "sudo iwlist eth1 scan" as well. But I can't turn on the interface without hanging the system and thereby destroying this post.

I just upgraded from the 64-bit version of Ubuntu 10.4 to 10.10 over the network using the Update Manager. But when I chose the "About Ubuntu" option from the System menu, I was surprised to see it say that I am running Natty Narwhal 11.4. My system is a Linux Certified LC2464T [URL]

Fedora Networking :: Intel PRO/Wireless 2915ABG Not Working On Acer Travelmate 8100 12?

Dec 29, 2009

I have installed Fedora 12 on my laptop and subsequently spent most of the day trying to get the wireless connection to work. Looks like I am not alone with Wireless issues Through searching and reading today I think the problem lies with the fact that the wireless on/off switch is not working. Under Windows, when I press the wifi toggle switch it starts flashing orange. I haven't managed to get it to do anything under Fedora.

Ubuntu Networking :: 9.10 - Disable PRO / Wireless 2915ABG (Thinkpad X41)

Feb 19, 2010

I use this Thinkpad mostly for work while traveling, and wireless connectivity is not a big issue for me. Battery life is a big issue, however. I've just converted from Mandriva. With that, I was able to disable the wireless adapter so that it did nothing at all on boot - and only started on my instruction. This made a dramatic difference to battery life! How to achieve this in Ubuntu? The file attached gives all the info about my wireless set-up as it stands.

Ubuntu Networking :: Hang On Reboot When Connected To NFS/ldap Server Via Wireless

Jun 18, 2010

School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.

So here is what works:

1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.

2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).

3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.

What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:

Code:

The system is going down for halt NOW!

acpid: exiting
init: cron main process (1011) killed by TERM signal.
init: tty1 main process (1365) killed by TERM signal.

[code]...

If I try ctrl-alt-del at this stage, it says:

"init: rc main process (3030) killed by TERM signal"

"Checking for running unattended-upgrades: "

And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.

Ubuntu Networking :: Intel Pro / Wireless 4965 AG Frustrations

Jan 19, 2010

After wading through all of the bug reports filed regarding the Intel 4965 AG wireless adapter, trying various suggestions and not finding any solutions to my problem, I've finally decided to scrap the idea of actually being able to get my Toshiba laptop to connect reliably to my wireless network with Ubuntu 9.10. This wireless adapter worked absolutely flawlessly with 8.04 Hardy. I took the plunge once again this week and thought I'd try again to get 9.10 working on my laptop but it's a no go with the Intel wireless adapter (same problem with 9.04, it just doesn't work). You would think with newer versions of drivers and kernels that the same hardware that worked in a previous version, would continue working with newer versions.

Anyway, enough of my frustrated ranting... I need to find a replacement wireless adapter for my laptop that WORKS FLAWLESSLY with 9.10. When I say flawlessly, I mean you plug it in, boot up the laptop and it works all the time, every time. No fooling around with drivers etc... Either a PCMCIA or a USB wireless adapter that is currently available for purchase. I've waded through the sticky on the forum about which adapters are supposed to work, but I'm really hoping that someone here is using either a PCMCIA card or USB card and could please point me in the right direction. It's kind of funny, I purchase my Toshiba laptop because I read reviews here in the forum about how great it worked with Ubuntu 8.04. How all the hardware was recognized and worked out of the box. It did... with 8.04. Everything still works with 9.10 except the wireless.

Ubuntu Networking :: Intel 3945ABG Wireless Will Not Connect To WEP?

May 21, 2010

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

Ubuntu Networking :: Intel PRO/Wireless 2200BG Not Working

May 31, 2010

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.

Ubuntu Networking :: Intel 4965agn 10.10 Wireless - Can't Connect

Apr 14, 2011

I'm trying to set up ubuntu on my netbook, the brand and make is obscure, essentially, this is a no-name brandless build from china, but a pretty decent lappy. Atom N270 Intel 945GSE based. initially it was equipped with a 3DSP wifi/bluetooth mPCIe combo card, which is proprietary and didn't work on ubuntu (didn't even show up as a device), so I got an intel 4965agn based on compatibility list somewhere in the wiki.

The problem I have is that I see networks, but can't connect at home or at work or anywhere, it just hangs in the connecting status and then throws the authentication popup at me again (pw is all correct). I tried looking around at similar problems, some have wpa_supplicant related issues, but doesn't seem to be the same as mine.

I tried creating an unsecured network using my macbook's airport, and same thing happened with ubuntu... hangs in connecting status then drops, so it doesn't seem to be WPA. I don't have the device on me to do all the iflist iwlist checks for you, but if you could give me some clues, I'll post back when I get home.

Ubuntu Networking :: Lenovo T61, 9.10 And Intel Corporation PRO/Wireless 4965 AG Or AGN?

Jan 16, 2010

what is really a rant disguised as a question, but does anyone have this combination working? My NetGear router shows the connection as allowed from the MAC address in the router logs, And I can see the network I want to join in the list of visible networks from the laptop, but dmesg shows Ubuntu disconnecting with

WPA-PSK [TKIP] only:
wlan0: disassociating by local choice (reason=15)
WPA-PSK [TKIP] + WPA2-PSK [AES]
wlan0: disassociating by local choice (reason=3)

I'm sure there is a simple explantion that has been sufficiently buried somewhere but after several hours of googling and searching the forums here I can't find it. Anyone want to help out an old man RTFM?

I'm getting really disappointed here lately - things are getting worse, not better. In my case in particular I have this laptop with supposedly open and supported drivers and they don't work, however, the exact same distributuon on a Dell D830 with a broadcom NIC does. under 8.10 and 9.04 this worked out the box - just logged in, gave the PSK and away we went. I can't see the attachment I just uploaded so to include the information requested in the "how to get help" post, I'll put it all here inline...

Ubuntu Networking :: Random Wireless Disconnects - 9.1/Toshiba/Intel 3945abg?

Feb 22, 2010

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.

Ubuntu Networking :: Constant Wireless Disconnecting With Intel Based Card

May 2, 2010

This is a fresh install of Ubuntu 10.04 on a Dell XPS M1530. I'm getting very frequent disconnects to my wireless network, despite good signal. I have wicd and nm-applet running side by side, wicd doesn't work by itself and nm-applet won't get a new IP after reassociating with the AP.

Wireless connection is steady in Windows 7, so I'm guessing it's a problem with the driver.

Ubuntu Networking :: 10.04 & Intel 4965 Wireless - Can't Ping The AP Or Any Other Computer On The Network

Installed Ubuntu 10.04 on my Sony UX280p with Intel 4965 wireless. Ubuntu detects the card without issues (as far as I can tell). I can see all access points in my area and select my access point and pair with it. I get a DHCP address from the AP (if ifconfig is to be believed) and iwconfig shows the ESSID of my AP but I can't ping the AP or any other computer on the network, nor can I ping the sony from any other computer on my network. Last year I had installed 9.04 on this computer and wifi worked out of the box without any issues.
