Ubuntu Networking :: 11.04/Thinkpad E420/wireless Not Working
May 29, 2011
I have a Thinkpad E420 and am having major problems getting the RTL8188ce wireless to work. I'm running 64-bit. I was following instructions from this thread: [URL]
I installed the drivers from the Realtek website for the updated kernel (URL is in the previous thread link). Modprobe didn't work, but it looked like wireless drivers were installed anyway after I did "make install." But I still run into this problem in the network manager: Enable Wireless is checked, but above it, Wireless Networks is greyed out with "wireless is disabled" underneath.
Later in that thread, someone posted a link to a PPA with drivers that should work. I could not get the PPA to work through terminal, but I did manually download and install those drivers. Same problem.

what it takes to get my wireless back up and working. It used to work fine under 10.4 My laptop is a IBM Thinkpad T42, that uses Intel wired and wireless nics. (correction, looks like the wireless nic is actually Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC (rev 01) )

I have Ubuntu 10.10 on a thinkpad X201. Wireless was working, but has stopped. It still works in windows, so it is not a hardware problem. iwlist wlan0 scan sees the available networks, but I cannot associate with any of them, including my own.
Last night was my first attempt to connect to a secured network, and nm-applet failed to make the connection even after entering the WEP encryption key and SSID. By turning networking off in nm-applet I was able to manually bring up the connection by editing /etc/network/interfaces and using ifup wlan0. (nm-applet seemed to be interfering as long as networking was turned on there.) Wireless was working perfectly until I rebooted. Now I can't get it to work at all. (There were some partially completed security updates which completed when I rebooted. I hope this wasn't the cause of the breakdown.)I notice that wpa_supplicant is always running. I tried killing it in case it might be interfering with the connection process, but something keeps restarting it.

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.

I have a pretty new Lenovo Thinkpad L412, with Ubuntu 10.04 LTS. I can't log in to any wireless network (I have dual boot with Win 7 and it works there). The available networks shows up in the list but I can't connect them, "no network connection" it says.

I just recently purchased a Lenovo Thinkpad e520 and I'm wanting to put Ubuntu 11.04 on it. I downloaded the 64bit iso and burned it to a thumb-drive, just before booting the thumb-drive. I have not yet installed Ubuntu, but rather I'm still running it from a thumb-drive. I want to make sure everything will work fine, before installing it permanently.
However, it doesn't appear as if any drivers for my wireless card were loaded, as I can't view the available wireless networks. I successfully installed Ubuntu 11.04 on my desktop several months ago and I haven't booted into Windows since, -not one time. Therefore, I'm hoping to have my new laptop run Ubuntu as well.

I have a Thinkpad W500 with:
Code:
Network controller: Intel Corporation Wireless WiFi Link 5300
I have Ubuntu 10.04 32bit installed:
Code:
Linux dani-laptop 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC 2010 i686 GNU/Linux
It has been working fine since I installed 10.04 but recently (end of last week I think) it stared dropping the wireless connection very often. So it will disconnect and reconnect, but I can't seem to find a pattern, sometimes it goes for hours without an issue and sometimes it does it several times in a row. Below is an extract of syslogs from when this happens. But not sure if what I need is there... the only weird thing I can see is:
Code:
Oct 27 18:58:33 username-laptop wpa_supplicant[1296]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Code:
Oct 27 18:58:32 username-laptop wpa_supplicant[1296]: Trying to associate with 00:1e:be:a6:c0:0f (SSID='accessp' freq=5280 MHz)

I tried fix I pointed here http://fedoramobile.org/Members/MrHappy/troubleshootingNetworkManager fails to see wireless networks with Intel 3945 chipsets(solution deals with the kernel module not with NetworkManager)but nothing to do. My actual problem is I can't see my wireless network but I see just those of my neighbours.I know mine is working because I can connect to using a Mac and windows.

I've been running Ubuntu 10.10 on this ThinkPad for a couple of months now, with absolutely no problems at all.The wireless was working fine earlier today out at a coffee shop. When I got home and turned the computer on, the network applet just showed a "Wireless is disabled" message.I poked around for a while, mucking with whatever I could (limited, unfortunately, I don't have great linux-fu) and doing the ritual reboot to see if that would get things going.I then spent some time reading through forum threads here, but didn't find any answers.Below are the results of the various commands as described in HOWTO post a Wireless issue (ticket) sticky threadMachine brand and model

Edit: after upgrading everything using a usb to ethernet port converter ndiswrapper is working perfectly
I do not have internet access on a laptop I am trying to upgrade. It has no ethernet port. I may resort to buying a USB to ethernet adapter but I spent more than I would like to have already. I have tried every command in the HOWTO for wireless difficulties and posted the output.

I recently installed ubuntu 10.4 LTS on my IBM T60 ThinkPad, (Love Ubuntu! Will Never go back to Windows)
But now the problem is as followed.: When i'm at work where they have an open (Non protected) WiFi spot i have no problems connecting at all. But as soon as i'm at home or with friends which have WEP/WPA/WPA2 encrypted routers it is impossible to connect, to none of them. not Linksys, not Dlink not Thomsom, simply none. For days i've been hunting the internet for information about this problem but it is impossible for me to find the solution. I've read the Wireless troubleshooting manual from Ubuntu and did all the checks and tests and everything seems fine. The card is an Intel 3945ABG, and in the new Linux Kernels its already pre-installed. It's so frustrating not beeing able to use the internet in a proper way..
Note:
I installed wireshark to experiment at my workplace but its finding nothing at all even though its connected to the internet/LAN Etherape works fine though.

I want to switch my laptop from XP to Ubuntu, but right now, i cant risk installing it. i dont want to have it partitioned so i can dual boot, so for now i only run the try-it-out mode.Before i consider installing though, i want to see if i can get everything to work ahead of time, that way im not regreting instalation. I have a Compaq Presario V2000 laptop, with 55GB hard drive and 516MB ram. So far, the trial mode is working great, but the wireless will not work. Ive tried to install the driver, but i am unable to do so. I have looked this up, and i have tried many things, and so far, none have worked.I was wondering if it was just part of the trial thing or not, but it is a Broadcom Wireless BCM4318 driver

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

For some reason, i just cannot get my wireless to work in xubuntu. When i click on the network-manager applet, it only has the wired network tab and VPN connections, there are NO wireless networks displayed. I have also tried iwconfig, which returned

Having problems with getting wireless to work on my laptop. My problem is that the plasmoid-network manager shows that I am connected to my wireless network (with SSID "Fatty"), but I can't get onto the web. Browser, chat application, twitter client - nothing is able to connect. Followed the instructions given by the stickies at the top of this forum. Here is what I got.

I have just installed openSuse 11.4 KDE 64-bit on a Dell M1330. When I click on my networking panel, it says WLAN interface is unavailable. I've followed the steps in the stickied post and found the WLAN hardware info, a screenshot of which is below:Uploaded with ImageShack.usNext it says to do this - you need to look at the logs, in particular the info in /var/log/boot.msg. To see this, you need YaST => Miscellaneous => System Logs and select boot.msg.In YaST there is no such option for system logs under miscellaneous, so I can't do that. The results of the sudo /usr/sbin/iwlist scan command produce the following:
root's password:
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

My wireless network is down. I got thinkpad x120e, chipset: Realtek RTL8188CE, driver: rtl819ce.
Here is what I did so far:
upgraded to 2.6.38-bpo.2-686
installed firmware-linux-nonfree
Added the firmware file from the repo since it's not yet packaged in firmware-realtek and reloaded the module.
'iwlist sc' shows: 'wlan0 Interface doesn't support scanning : Network is down'
'dmesg |tail -20' shows:
rtl8192ce:rtl92c_download_fw():<0-0> Failed to request firmware!
firmware 0000:04:00.0: firmware_loading_store: vmap() failed
I also tried the following commands:
ifdown wlan0 ; ifup wlan0
ifconfig wlan0 up
Relevant bug: [URL]
Step by step, in case someone is interested:
add to sources.list: deb [URl] squeeze-backports main
aptitude update
sudo aptitude -t squeeze-backports install linux-image-2.6.38-bpo.2-686
install this package: [URL]
get the first file: [URL]
add to driver:
mkdir -p /lib/firmware/rtlwifi
mv rtlwifi_rtl8192cfw.bin /lib/firmware/rtlwifi
modprobe -r rtl18192ce; modprobe rtl18192ce; dmesg | tail -20

Just installed 11.3 on an aging IBM Thinkpad X40. But the network (and xdm) does not work. I saw in the logs the cryptic message nl80211 driver does not support authentication/association or connect commands. This machine worked on 10.3, so this is a confusion. What should I try next?

Huh? I didn't set that... Tried the root password, tried the user password, none worked. The answer: Gosalia's team remastered Ubuntu with their password locking the keyring. Quite a funny situation.

This is completely baffling me..I have a Lenovo Thinkpad X301, which has been running OpenSUSE 11.1 for a while, with vanilla kernels from kernel.org, built and installed in the standard (i.e. not SUSE) way.
A week ago, I dupped to 11.2, and also installed kernel 2.6.38.4 . This was compiled with the gcc-4.3 available under 11.2. Everything worked fine (after the necessary messing around to get X working again).
This weekend, I dupped to 11.4 (via 11.3, of course). After more messing around to get X working again, things were working ok - using the same 2.6.38.4 kernel I'd built under 11.2. I then re-built the kernel. It appears to compile and install ok, and I haven't changed the configuration or the grub configuration. However, it doesn't load. Normally, I just get a blank screen after grub starts it loading. If I boot in basic VGA mode 0, then I get a few lines of messages before it hangs - it hangs complaining about APIC not connected to io bios, and if I boot noapic, it gets a few lines further before hanging after some message I don't know about (allocating 4 HET). I don't suppose that's relevant, anyway.
I've tried three different gcc versions, and two different linux versions (2.31 as well), and the same thing happens. This sounds like something going badly wrong with ld or as or something - but I don't see how anything could have happened that wouldn't have been noticed by thousands of others.

Just upgraded to the newest version of Ubuntu(unity), and my wireless isn't working. I have the 14e4:4315 Wireless Card so I followed this posts [URL].... And still have no wifi, when I click the icon in the menu bar it says under "Wireless Networks": "wireless is disabled by hardware switch", which ins't true because on my Vostro 1520, there is only one switch and it is in the on position. I've tried 3 versions of ubuntu and none of them work with wifi getting tired of it.

In the wake of a spate of posts complaining that wireless is not working in 10.04 here is mine. I'm on a (relatively old) AMD Duron 1.5Ghz, 1.5G memory with a VIA KM-266 motherboard. Wireless worked fine in 9.10. With a fresh install of the new 10.04, the usb wireless adapter is not detected, the tab to add a new wireless connection is grayed out, starting the KNetworkManager (did I got the name right?) does nothing (that is, no application starts), etc.note: if you are wondering how I am accessing the internet, I just fired up the 9.10 live CD, which as you can imagine is not the most practical thing in the world.Here is the info. The commands lsusb and lspci spit the following:
Code:

I just upgraded to Ubuntu 10.4.2. The wireless worked perfectly in 9.04, but did not not work at all in 9.10, and now 10.4.2. I'm running a Planex USB wireless dongle on an ancient ShuttleXPC SN41G (circa 2003) - the wireless dongle is an XLink Kai GW-USMini2N. I'm connected right now on the Shuttle via Ethernet cable, but would really like to get the wireless up and running again. Here's all the info I could get as per the pinned topic instructions:
