Ubuntu Networking :: Wireless - Lost It - 'wmaster0 No Wireless Extensions', But Then Refers To Wlan0 As The Wireless Connection
Mar 28, 2010
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.

have a dell Inspiron 1501 with ubuntu 10.0.4 I want to rename my wireless card from eth1 to wlan0 as I use conkyrc and it will not read my wireless strength or my ssid cuz it thinks it's a ethernet card and not wireless card. I know this for a fact because peppermint os my wireless card was wlan0 and it worked just fine.

I used to be able to connect to the net using my laptop {Ubuntu 9.10 on Compaq nx7400.}by means of wi-fi . I do not know what I have done but I lost the facility to connect to the net.I noticed the Network Manager disappeared from the notification area. I manged to put it back. It detects the signal from the router and after entering my password it displays Connection Established but I still cannot access the net and does not load any web pages. I have the same Ubuntu 9.10 Desk on a memory stick, when I use it on the laptop it works fine.
I enclose a screenshot of iwconfig.I did sudo lshw -C network and it shows DISABLED. How do I enable it ? Are there any other info that I should supply and what and how.

I installed a clean installation of ubuntu 10.04 inside Windows 7 and wireless worked normally in the beginning that I downloaded and installed all the updates "I selected without updating Grub".On the first reboot after updates, the wireless icon disappeared from the panel and could not connect to the internet although the settings in the Networking tools were correct.

I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.
It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.

I have an odd problem in that my wireless connection is okay until I close the laptop. When I open it back up, I'm unable to reconnect. This problem first occurred after upgrading to 9.10. I can reconnect after restarting. I tried several things before breaking down and reinstalling 9.04. After installing 9.04, everything works great. Any suggestions on what is going on before I try upgrading to 9.10 again? I have a Dell D600.

I have fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.

I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.

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.

I have a fresh install of Karmic on a older compaq laptop. I initially had LAN access, but not wifi. I added a few Broadcom packages using synaptic, and then neither worked. Then I removed the same packages, but I still have no internet access, LAN or wifi. Here are some of my settings. vincentertainment@vincentertainment-laptop:~$ iwconfig

Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.

currently running karmic on an old gateway laptop with kernel 2.6.31-22-generic and, as is par for how I handle challenges, I've jumped in with both feet - which is to say this is not a dual-boot situation. I've spent some time reading the forums (and other sources of information) and am grateful for all the knowledgeable people who are willing to share what they know.
My operating system seems to be functioning properly.I can get online via ethernet, but not via wireless. I have a lucent orinoco gold PC24E-H-FC (PCMCIA) card, which the computer isn't seeing. I am trying to follow the instructions here: [URL] to install the driver. Everything is going well until I get to the sudo make line. At that point I get the following display:
make -C /usr/src/linux-headers-2.6.31-22-generic M=/usr/src/orinoco-0.15rc4 KERNELRELEASE= modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.31-22-generic'
/usr/src/orinoco-0.15rc4/Kbuild:8: *** Wireless extensions are not enabled. Stop.
[code]....
how I can fix it so I can continue on with the instructions. (For the record - if I just continue on, I can change directory in the next line, but I cannot remove either hermes or orinoco as "no such file or directory" seems to exist.)

I'm relatively new to Linux. My netbook ran updates yesterday for Ubuntu and now I am unable to reconnect to wireless network connection. I am using WPA2 encrypted security. I am able to connect via wired LAN. Also, when I went to connect using USB mobile connection, I get an error "unable to mount location". I get the same error if I try to connect my external CD drive. I am using Ubuntu 8.04 with Gnome desktop (2.22.3) on a Dell Mini 9.My wireless device is using Broadcom STA Wireless driver for an 802.11 wireless card.

i installed ndiswrapper and ndisgtk, then using my thumb drive installed my .inf file (tried in the terminal as well as ndisgtk and both worked succesfully). when i run "sudo ndiswrapper -l" my wn311b device is shown, and the chipset to be working properly. now when i run "iwconfig", Wlan0 is not listed. also i blacklisted the drivers "b43, b43legacy, ssb, and bcm43xx", could this be the issue? im running the newest build of ubuntu which i installed today on this computer for a dual boot drive with vista.

The adapter I purchased (Zonet ZEW2508 ) uses the Ralink 2070 chipset - a fact that originally excited me because Ralink seems to be fairly loving to the Linux community. However, despite my best efforts I can't get the thing to work. Initially I tried following directions to set up the driver you can download from the Ralink website. The directions I found were written February first, and Ralink updated the driver February eighth - so as far as I can tell the directions no longer work. After screwing around trying to figure that out for a while I decided to give ndiswrapper a go.
Initially this seemed promising. I just harvested the drivers from the CD and followed one of the many ndiswrapper directions available - most helpful seemed initially to be the Ndiswrapper Troubleshooting Guide found in this forum, however the solutions offered there didn't work either. When I throw an ndiswrapper -l into the terminal it looks promising at first, it tells me the driver is installed and the device is present, but it just doesn't work. When I try iwconfig, or iwlist scan it tells me "no wireless extensions," and "interface doesn't support scanning" respectively. The only devices even listed are lo, eth0, and pan0. There's no wlan0 or anything of the sort.

I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network. Tried a few bits of poking it blindly with a stick:
matthew@ubuntu:~$ lshw -C network
Warning: you should run this program as super-user.
*-network
Description: Network controller
Product: BCM4312 802.11b/g LP-PHY
Vendor: Broadcom Corporation
Physical id: 0
Bus info: pci@0000:0c:00.0

Clock: 33MHz
Capabilities: bus_master cap_list
Configuration: driver=b43-pci-bridge latency=0

*-network .....
I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either.

I have searched and have not found anything specific to my issue. I am currently using NDISWrapper to load the bcmwl15 driver and when it's active it works beautifully.Problem is sometimes at boot, the card doesn't "turn on" and I don't know how else to describe it. The OS does not even detect that the hardware is present. I have disabled wireless hotkey in BIOS. The only way to make the wireless card "active" is to reboot with the wiredconnection to the router. After doing that the wireless card "wakes up" and works awesome.Is there anything I can do to make sure the driver load at boot?mes I get the error that NDISWrapper is not modprobbed when I go to network configuration and if I wish to do i now? I don't know if that has anything to do with the boot sequence. Using the <modprobe ndiswrapper> command as root does nothing permanant

Last night I went to Synaptics (in 10.4) and typed in bluetooth and deleted 3 packages to get rid of bluetooth (which my laptop doesn't have).
Unfortunately, I lost my wireless with it, and the network connections option in Preferences.
what the 3 packages are so I can reinstall them?
Or an easy to way to reset an installation to repair this problem?

I recently bought a D-Link DIR-655 router capable of 802.11n operation, upgrading from a DIR-624 router only capable of 802.11g operation. While my overall setup uses wired connections, other people in the house prefer wireless, and the upgrade was undertaken more for a hoped for increase in wireless range, rather than the possibility of increased speed, since the router is located to accommodate the wired connections. However, to test the 802.11n operation I bought a D-Link DWA-130 USB dongle for my now 5-year old laptop, which comes with an otherwise satisfactory 100Mbs ethernet port(eth1) and an 802.11g wireless card(eth0). By checking the dmesg | grep firmware output after I plugged in the dongle I determined that the necessary firmware was rtl8192sfw.bin, which I found on the web, and downloaded into the directory /lib/RTL8192SU.
A subsequent reboot and then YaST > Network Devices > Network Settings showed the device as wlan0, but not configured. I changed the Network Setup Method to ifup (since I can see no way to do a device configuration in Network Manager), and configured the device, and at the same time deleted the configuration for the existing 802.11g wireless card(eth0). I then rebooted, went back into YaST to confirm the wlan0 device was configured and the 802.11g device (eth0) was not, changed the Network Setup Method back to Network Manager, rebooted again. Making sure that the router was set to only transmit/receive using 802.11n I then typed iwlist scan. To my surprise, the output showed first that the supposedly unconfigured eth0 device seemed to be still active, for it found my home network, and claimed that the protocol used was 802.11g. On the other hand, the newly configured wlan0 device produced the message: "Interface doesn't support scanning: Network is down".
First, should I expect iwlist scan to work for a device that shows as unconfigured? And even if it should work, shouldn't it show 802.11n as the protocol, assuming that the router is in fact telling the truth? Is there any independent means to determine if the router is only using 802.11n as it claims? Second, the overall goal is to make the wireless network in the house 802,11n only, and since the dongle is backward compatible with 802.11g, I would expect to permanently unconfigure the eth0 device and use the dongle, both here and on the road. I do not need two wireless connections on my laptopThe laptop is running SuSE 11.2 as of about a month ago.
