Ubuntu Networking :: Wireless Adapter Not Working After Wlan.conf Update
Jan 19, 2011
I updated Ubuntu to 10.04 after which I noticed the wireless indicator lights on my HP laptop were continually flashing between blue and orange and network performance seemed slow. I did some searching and found and implemented the following change to stop the flashing:
gksudo gedit /etc/modprobe.d/wlan.conf
Copy and paste the below line:
options iwlcore led_mode=1
Since making this change the wireless connection is shut off and I can;t get it to work at all. I first tried simply to remove the change to get back wher I was, but I can;t do that. Can sopmebopdy toell me at least how to get rid of this wlan,conf file ( it was created by the above command) so I can start over?
Coincidentally since making this change my Windows Vista OS fails to start because of errors attributed to a software or hardware change, of which there were none other than the Ubuntu wlan.conf change. . It may be unrelated but I am suspicious of the coincidence. I am running Vista and Ubuntu in a dual boot configuration and all ha run very well until I did the Ubuntu wlan.conf change.
I am now attempting a complete recovery of my Vista system, since it seems irreparably broken. Again coincidence or not?

I have just installed Ubuntu 9.10 on an Acer TravelMate 290E. I've got internet connection through the Ehternet Cable, but when I plug in the D-Link WLAN USB device, although the system recognises it, it is disconnected. How can I connect the WLAN USB device adn get it to work?

(For the record, I have already read the other threads. Either they don't work for me or are too difficult.) My laptop is an Acer TravelMate 250. I have installed Ubuntu 10.10 (2.6.35-28 generic i686) after erasing Windows 7. At first, the usb wireless adapter worked. Then, I restarted the PC because of some updates and it didn't work anymore. In "edit connections" I find "Auto SpeedTouch8350DB" which is the wireless connection (on my sis's computer it works). When it tries to connect, I'm asked the password but it doesn't work.

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.

As the title reads. My wireless adapter does not work when I boot from the Ubuntu 10.04 LiveCD. The adapter in question... tricky. It's this one: [URL]...- however, aside from a mention in one of the comments to a "Ralink RT2780", I don't see any reference to a make/model.
The software that ships with this product is indeed Ralink-branded, but again there's no mention of a specific make/model. So I assume it's just a driver issue, however I've no idea where to begin in my search for one as I can't identify its model number.

I have been searching for days on end trying to get my machine to detect my Netgear WG111T wireless adapter...and I've gotten absolutely nowhere at all.Most tutorials suggest I use ndigstk(sp?), which allows me to use Windows drivers for my adapter. I've been told many times to use the wg111t.inf file, but all I've been able to come up with is the w11t.inf file. Whenever I start up the Windows Wireless Drivers application, I usually get a popup which tells me "Unable to see if Hardware is detected"--yet when I hit the OK prompt, next to the w11t.inf file, it says "Hardware detected --Yes", yet I still have gotten nowhere. I grasp some basics of Linux, but overall I'm still pretty new to it--and I have a big headache from the whole thing.
EDIT: I forgot to mention, my install is 9.04, so if 9.10 resolves this, how would I go about upgrading without downloading an ENTIRELY new disc (I have a horrid internet connection, it'd take HOURS to download the 699MB ISO, so perhaps make that a last resort)

I upgraded to Ubuntu 10.4 on my Dell Inspiron 6400 yesterday (32-bit). Everything was running great, but when I turned it on today my wireless adapter is no longer working and the hardware switch doesn't do anything. It's working in Windows fine so it can't be the hardware.Here is some information:
Adapater name: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Code:
iwconfig:
wlan0 IEEE 802.11abg ESSID:off/any[code]....
Restarting the network with 'sudo /etc/init.d/networking restart' didn't work.I've tried Ubuntu several times before but usually there is one small issue which makes me go back to Windows. I love 10.4 so I hope I can get this working so I can stay on Ubuntu!

I tried getting a Belkin USB Wireless adapter:N150 to work in a fresh installation of 10.4 with no success. After reading several forum posts I tried both solutions with ndiswrapper and the XP driver and with the Ralink native driver with no luck.

I have a Toshiba MX35 laptop it's a little old but does the job. I'm have a problem getting the wireless to work. I can boot a live CD either Ubuntu 10.10 or Fedora 14 and they will see the wireless card. The card is Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01).
I have Ubuntu 9.10 installed and that is the OS that is having the problem seeing the wireless. The computer will not handle Ubuntu 10.10 (at least it won't handle the desktop effects under Ubuntu 10.10) but handles them just fine under 9.10 and that's why I have 9.10 installed. I really need the Wifi to work because I'm going to travel in a few days.

I'm not a new user to ubuntu but I'm stuck with a driver issue on a wireless adapter upgrade for ubuntu 10.04 lucid lynx. I'm running an acer aspire am1201-e1622a with amd athlon x2 64 bit processor, however i'm only running the 32 bit version of lucid lynx. The following are a few outputs of some commands that might assist in finding the proper driver. Before though i will tell you what i have done.
I have installed a few different drivers from windows wireless driver installer such as the xp and vista 32 and 64 bit versions with no success in the computer actually recognizing that i have a wireless adapter installed. The windows wireless driver installer said that hardware was present but i was unable to scan for networks or even see that i had a choice to do that. This meaning that it didn't show i had wireless capabilities in my network manager. i tested this with gnome network manager which is the default manager for 10.04 and also with wicd with no success.
Following these tests i attempted to install a driver from source following the instructions on another forum. This allowed me to manually turn on the wireless adapter but i was still unable to find any networks. This meaning that wicd was able to see that i had a wireless adapter installed but it for some reason was unable to see any wireless networks around. I'm 100% sure my router is in range and that it is configured correctly. I have 5 other computers connect to this router along with some of them being ubuntu.

I buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.
Notes:
- I have another PCI Wireless adapter which works fine.
- The problematic adapter works great on windows.
- A driver CD came with it, including a linux driver which I wasn't succesfully installed.
- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.
It took me dozens of surfing the web hours, and too many restarts,

As the title says i updated my system which then needed a reboot. I also installed Mixxx djing software to try it out. So i thought id just restart the system. Usually when i boot into my desktop wireless automatically can connect to my router but not this time, wired only for now... i know theres tons of wireless issue threads but some more experienced users will be able to get straight to the point and run through some diagnostics with me.

This is my startup routine:
I log on and Network Manager shows no wireless adapter.
I go to System > Administration > Network:
There are two entries in the Devices tab: Wireless and Ethernet
As soon as I double click the Wireless device and the configuration pops up, the device starts working (no changes to the settings are made)
I have the following set to ON:
- Controlled by Network Manager
- Activate device when computer starts
- Allow all users to enable and disable this device

My PC has a broadcom wlan adapter. When I clean installed Fedora 15 about two weeks back, the wifi wasn't working on its own. I searched the internet and found out that installing broadcom-wl and akmod-wl would solve the problem. I tried it, and the wifi started working after that.
Wifi not working means there is no wireless option in the network settings and the wifi indicator light is off.. when wifi started working both of these got fixed
Now i did a yum update yesterday, after which my wifi has stopped working again. No use of reinstalling broadcom-wl, akmod-wl, or even kmod-wl...
Code:
lsmod
gives

I configured my Xubuntu laptop to work with my Netgear Wireless router to connect to the Internet. I was able to connect, and downloaded Hardy updates of 184 MB. After installation of the updates, the system prompted me to restart. The Wireless network is not working since then. Tried reconfiguring, but to no avail. The proprietary drivers for my wireless network card have been downloaded and installed... remember, it worked well enough download the updates! Posting this from my Windows partition using the same wireless network A previous thread [URL]...k+Hardy+update) with the same issue seems to have hit a roadblock...
