Ubuntu Networking :: IBM ThinkPad T60 Ubuntu 10.4 LTS Wireless Connections?
Jan 12, 2011
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.

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 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 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.
lspci:
Code:
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

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)
Oct 27 18:58:32 username-laptop NetworkManager: <info> (wlan0): supplicant connection state: completed -> associating

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.

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 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 have been using Ubuntu for a couple of days now and I am starting to like it alot. I decided to install it on my laptop, but getting it to connect wireless is becoming a problem. I have been searching all day on how to fix this but nothing so far has helped.I had Windows 7 installed before and it connected fine.

So it snatched up this old Dell Inspiron 5100 with a WN511B wifi card. When I plug the card into the slot nothing happens and no wireless connections show up. Can someone walk me through on getting the wifi card to work?

I have an Acer AspireOne D255 netbook. I just installed Ubuntu Netbook Remix 10.10 and it looks pretty sweet.Right now, I'm on a wired connection. It's not detecting any networks, and I know at least my home wifi should show up (and usually we can get onto our neighbors!)I used to have a different model of an AspireOne (I think it was 531h but I'm not 100% sure) with UNR 10.04, and my network was detected right out of the box.
This reminds me of when I installed the desktop version of 10.04 on my iMac. I couldn't bring the wired connection to the room it was in, and my wifi didn't show up on it. I just gave up because I like my Mac so it wasn't a *huge* deal. but I definitely don't want to use this stupid Windows 7 Starter that comes on this netbook!

I went to get online on my laptop this morning, and have no connection. When i click on the icon up top in the task bar, it only shows vpn connection. It does not show ANY wireless connections at all. I checked, and the enable wireless is checked. It just does not pick up any connections.

I own an hp dv9000 laptop, it comes with a Broadcom STA Wireless card... I currently have my laptop connected to the internet through a wired connection, but there is no option at all for wireless.I've already installed the Additional Drivers to install the Broadcom STA Wireless Drivers, and after I reset, there was no difference, no option to choose wireless instead.

I'm working right now with ubuntu 11.04 on my asus ul30vt-x1, my wireless n network is working on a linksys e3000 router, my issue is basically with long file transfers. When the issue started i was reaching speeds of 100 Mbps through my wireless network even when I'm connected at 150 Mbps. However when at this speed, I don't know why, the connection is dropped after some minutes or even seconds. I made some testing on windows, I'm reaching 70 Mbps there and no problem at all with dropping the connection.
So my conclusion is that for some reason the linux driver, in my case, is not able to handle such speed of 100 Mbps. I know that a wireless network will have a throughput of aprox 60% the wireless speed. Right now im trying to apply traffic shapping to my transfers so i can get 70 to 80 Mbps, its being working so far.

So my machine is doing a bunch of strange things and I want to reload it. But I would like to save some of my settings, the most important of which to me is the wireless networks that I've configured from all my customer sites. There are A LOT of them, and I don't remember all of the settings so it would be nice to migrate those to my new install without having to redo them one by one when I arrive at a customer site.

Running Ubuntu 10.10 on a Dell 710m. Fresh install of OS yesterday. Initially I had wired connection but no wireless. So I started chasing threads & trying different downloads & commands [WITHOUT KNOWING essentially what I was doing; throw your rocks at me HERE] & now I have lost the wired connection also.
Also:
[a] If I go into System > Administration > Additional Drivers, I get "No proprietary drivers are in use on this system."
[b] As far as being able to copy a downloaded driver [using a working M$oft machine with net connection] onto an SD card & transferring that driver to the Dell laptop, I have tried formatting 3 different SD cards with the Dell, & each time I come up with various failure errors--& I have no idea why something as simple as formatting an SD card isn't working.

Can anyone tell me if there is a way to change the behavior of Network Manager, so that it will only automatically connect to certain wireless networks which I specify, and not automatically connect to others I may have previously used. For example, there are a lot of wifi networks called "linksys", and I don't want the program to automatically try to connect to whichever one it finds.If someone can tell me in which file(s) the list of these connections is stored, I might be able to write a script which will edit that list on startup.

i'm using a dell n5010 recently i installed ubuntu9.10 in my laptop and it doesn't seem to detect wireless connections, so, i googled it and downloaded a driver from broadcom and tried to install it as per the authors instructions and nothing seems to work well, the broadcom drivers are not detected in the additional drivers and when i try to install linux-wlan-ng tarballs it doesn't seem to work even, though i have gcc(i think thats it), so, i installed my windows driver through nsdgtk but it says that it is "unable to see if hardware is present" but, when i click ok on the error the wireless network applet says the hardware is present and when i click the network configuration tool it gives the error message "could not find a network configuration tool" and after configuring my network with network tools in administration it says "no wireless extensions" when i type 'iwconfig' and there is no ip address when i type "ipconfig".

I'm getting really tired of using windows, I love ubuntu but theres a big problem. I have a BTHomeHub2 and whats annoying is whenever I goto wireless connections there's only a bt home hub but its not my one. and I have tried connecting to hidden wireless network and nothing worked. I have a desktop pc with a usb plug in BT voyager that picks up the router but it will only find the one down the street not mine. It works fine when using Ethernet.

Just had an issue crop up where connecting wired network seems to stop wireless connections from getting an IP (happens on multiple networks both while the cable is plugged in and once it's been unplugged; also persists across reboots). Machine is a Dell Latitude 2120n with UnionFS running. Connection was working fine prior to the wired connection

My current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.

What I want is quite simple, I have my PC running Linux Mint 5 (Elyssa), and I would like to connect it to both an internal network, which has a file/print server, another machine and will soon host a small cluster. I also have a wireless router connected to the tinterweb.
The thing is using my ethernet I want to connect to the internal network whilst simultaneously using my wireless to deal with the internet, I want to keep the internal network off the net as it really doesn't need to be connected. I can connect to my internal quite happily and also my wireless but not both at once.

I installed Nvidia drivers according to the post in HowTos section. It downloaded a different version of the existing kernel, i guess. And the kernel using which I downloaded, when shows up GUI, looks like a Safe Mode of Windows. So I boot the kernel that it downloaded. And there the problem is that in Network Manager applet, it doesn't show me the wireless connections. It doesn't even show the Enable Wireless checkbox upon right clicking it. How to get it back?

My wireless is flakey -- dropped connections, poor speed, etc. As diagnosis, I loaded the 'wavemon' utility so that I might watch the radio and signal and noise.Things will be good, then fall off, then get better, then go away entirely. Repeat continuously and randomly. For these experiments, my laptops -- more than one -- are on a table.The table is roughly 15-20 ft laterally from the access point. The access point is also 8 ft above the floor vs. 3 ft table height.(grin) While the signal "wobbles" everything else is mechanically stable and otherwise not moving.

I'm trying to get wireless working in F10. Using pci wireless card with Atheros chipset. To be sure, I tested this hardware with a PCLinuxOS Live CD. Connects to AP perfectly.
Hardware drivers seem all OK in F10, and ifconfig shows wlan0 as expected. When I use the Wireless-Assistant 0.5.7 there's no connection.
Actually, the AP logs show numerous connections and disconnections.
Preferring CLI, I'm using a drop-dead simple wpa_supplicant.conf as follows :
