Ubuntu Networking :: Unable To Scan Or Access Any Wireless Networks - 10.04
Jun 7, 2011
Machine is an MSI U130 netbook running Ubuntu 10.04.2 LTS 01:00.0 Network controller: RaLink RT3090 Wireless 802.11n 1T/1R PCIe interface
Code:
wlan0 RT2860 Wireless ESSID:"" Nickname:"RT2860STA"
Mode:Auto Frequency=2.412 GHz Access Point: Not-Associated
Bit Rate:1 Mb/s
[code]....
I realize that Ubuntu recognizes the card, but I'm not sure why it's not picking up any networks that are around and says "disconnected", even though I've made sure that the wireless network light is enabled on the netbook.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

I've configured the device for my network's settings in YaST's Network Settings tool. Is the card turned off by the kill switch? Where do I find the kill switch?

I have configured a wireless pcmcia card using ndiswrapper. I'm sure that works, as with the command "iwlist wlan0 scan" gives me back
the list of detected wireless networks. At this point I was wondering: is there a way to detect the new interface (wlan0) with network manager? Even after enabling the wifi card the network manager gnome applet always finds only eth0.

New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.

Right so I just bought an Acer TimelineX with a Broadcom BCM43225 BCM43225 802.11b/g/n WiFi card. With this card I am not able to detect any wireless networks and after googling around I found out other people have had similar issues. But my problem is kind of unique in the sense that I'm using Backtrack as my Linux distribution (I'm not a blackhat or anything, more of an enthusiast with no malicious intentions) Also I'm not a God at Linux so if you have any solutions please be verbose! I tried the following: [URL] But the Makefile spits out a syntax error. (Makefile:29: *** missing separator. Stop.)

I'm trying to install Ubuntu 10.04 on my Toshiba A200-12U laptop (with an Atheros AR5007EG wireless card), but networking is being problematic.I entered Network Configurations and tried to get 'Auto eth0' working -- I went to Edit > IPv4 settings and filled in 'Addresses' with the details of my connection:
Address: 192.168.1.254 (the local IP of my router)
Netmask: 255.255.252.0
Gateway: 94.195.208.1

I bought this wireless card because alot of people said it worked out of the box and it almost worked... Ubuntu recognizes it and the wireless module is activated I just can't seem to scan for networks or connect to them... So I am listing some outputs for you guys and hopefully there is an easy fix.

I have installed Ubuntu for netbooks on my four year old laptop and of course the wifi card is unable to search for wireless networks when I'm booted into Ubuntu. I do have the driver software on a recovery disk. Would installing it in Ubuntu fix my problems?

I have a Linksys AE1000 wireless adapter and I used the post found here to install the drivers.I've figure I installed the drivers successfully because when I use "iwlist ra0 scan" I get a listing of available networks.The problem is, I can only connect to unsecured networks. For instance,
Code:
sudo iwconfig ra0 essid "unsecure network"
The above command connects me but the one below doesn't

While staying at a hotel that offered wireless Internet connection connection I was not able to access their network. I contacted their technical support 800 number and was told that the north building server had been down for 26 hours. I moved to a south builing room. Same problem. I went to McDonald's, which had wi-fi connection. Same thing. My laptop was not able to make a connection.
My question is as follow:
How do I find out:
1) whether it is a problem with my new Ubuntu version (10.04)?
2) my wireless card in my laptop is no longer working? Are there any tests that I can run?

I set up an older computer with Ubuntu 9.10 and tried to get my Linksys AE1000 Wireless N adapter to work. My first mistake was not checking in advance to see if this adapter would work, but I have taken the leap and I am intent on making it work. I ran lsusb and it gives me a device number (13b1:002f) so I know it can be seen and I have also installed indisgtk the GUI for Wirless drivers. I have tried some suggestions from other posts to no avail.

I am having trouble connecting to 1 particular wireless hotspot. It used to work in Ubuntu 10.10, but after upgrading to Ubuntu 11.04 it sees the Access Point, tries to connect but never succeeds. I can however still connect to my home router. Both use WPA2, both have a good signal. I have an ASUS UL30a laptop with a (output from lspci): Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) NIC I was thinking of installing the linux-modules-backport-net package?

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:
Code:

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.

My wireless network is being detected but it refuses to connect to it. I am entering the accurate passcode and I have tried doing various commands for it to work, but it is being stubborn.
Also, it would help to know which WEP Index to use and type of Authentication.

I am unable to access wireless network from my notebook. My configuration is Dell i5, 4GB RAM and 1397 W-LAN and I have F13. I can still access Internet through Ethernet using a LAN cable but the network monitor doesn't show list of Wireless networks which my room mate's windows 7 machine easily detects.
If anyone needs more info please provide me the steps to perform to find that out

1) I connect to the internet on a wireless router from my isp.
2) I use an older router for my media server (pc) to my ps3. The router given to me from my isp is the only one I can use to connect to the internet, yet it has the worst UPnP support (ie: none).
So with this current setup, I have to disconnect from the the wired network to be able to access the internet. So how can I access the internet while still connected to the wired network?

I have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.
