Windows crashed yet again so I thought I'd switch to Ubuntu. Install of 9.10 went flawlessly, everything looked great and worked perfectly. Next day after restart the wireless wouldn't connect. I looked around for solutions and used a wired connection to install wicd and suddenly wireless worked again. But next day after restart wireless wouldn't connect again -
I keep getting a popup asking for my WPA key despite the fact that I know the key is entered correctly. I decided to install 10.04, thinking maybe that would help. It didn't look like wireless was working but after a restart it worked and it worked again after another restart! Fantastic! But today, I'm back to square one. Using Windows again.
TL;DR - Wireless won't connect to the network which it can definitely see - repeatedly presents "Enter WPA key" prompt despite key being correct and wireless working flawlessly under Windows.

Wireless worked fine on live cd, but for some reason not after install. I think maybe the driver is not loading, but I am a pretty much still a noob, so my opinion isn't worth much. If it is the driver not loading, I don't know what to do to fix it. Here is my wireless output information.
Code:
linux:/home/linux # lspci -nnk

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.

how to make intel 3945 to work on RHEL5 ? Apparently that hardware is not officially supported by Red Hat so they do not provide drivers. what happens on my PC is after login I do not have the wireless card led is off and when I try to start the wireless connection I get
SIOCSIFFLAGS: No such file or directory
I'm not a real linux expert but I do use it since long time.

I've the Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) Ethernet Controller also a wireless slot (I've the wireless card DWL-G650+) When I turn on the pc and I go to "Ethernet Device", I see set: peth0 (Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) ETHERNET CONTROLLER) and also set "Bind to MAC address": fe:ff:ff:ff:ff:ff I've set manually the IP address (I'm under router). Status is "Active" but can't go on the Net. When I change to "eth0 (Intel EtherExpress/100 driver)...sometimes become "Active" an other times said that the MAC address is different or to check the cable because can't find the IP. What can I do?

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

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.

I cant seem to understand what happens to my wifi networking, i just installed ubuntu 10.10 today (completely erasing windows) on my toshiba satellite m645. Seems like my wireless card (the specs say its intel 802.11a/g/n wireless LAN) will only randomly detect the available networks or will connect only for a few seconds just after i just turned it on, then it will disconnect.

I had to send my laptop back for repairs, so I have an older Dell 1720 laptop that I threw the Hard Drive into, similar specs, just the wireless card is different. So what i need to do is somehow activate the driver for the Intel 3945 wireless card in this dell laptop.

I want to inject my card (Intel pro 3945 ABG) by using ipwraw-ng-2.3.4-04022008.tar.But I got a problem during the installation that driver.I want to use the driver in BackTrack4. But I can't connect to internet with BackTrack4, so I download it from Window 7 and copy to my thumb drive, and past to the desktop of BackTrack4.
Then I open terminal, decompress the tar file.
Another folder(ipwraw-ng) is appear on the desktop.
Then I change to the "ipwraw-ng" directory (cd /ipwraw-ng)
Then I compile with command (make) and the error start.

Wireless networking doesn't seem to work. When I try to create a new network interface with system-config-network, my wireless card doesn't show up. The following comes from dmesg:
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.0kmprq
ipw2200: Copyright(c) 2003-2006 Intel Corporation
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ipw2200: ipw2200-bss.fw request_firmware failed: Reason -2
[Code]...
I saw a post about this elsewhere and downloaded some firmware drives from [URL] and installed then. But, I'm really out of my league when it comes to this kind of stuff.

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 only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.

I just changed over from Ubuntu to Debian Squeeze and now my WiFi doesn't work. My computer is a Toshiba Satellite and the wireless card is Intel 2200bg. I think that's the name of it. That's the driver, anyway. My router is using WPA2, and using iwlist scan, I can see the network just fine. When I try to connect, though, it starts to connect for a while, says it's validating authentication, then says it fails. I've triple-checked my password and it's right.
