Ubuntu Networking :: Iwconfig/iwlist - No Wireless Extensions And Interface Doesn't Support Scanning?
Mar 11, 2010
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 just upgraded my system to Fedora 14. One thing I noticed after running some applications on it is that it is not possible anymore to figure out on what frequency a wireless interface is using. If I set a wireless interface to monitor mode and perform the iwconfig or iwlist command, in the past, I could see the frequency used on the interface, but now, this information is not present anymore. My wireless interfaces are in monitor mode.
Has the frequency information been removed from iwconfig or iwlist commands? If it has, is there another way to report this information?
I have only just got my first netbook and when I first installed 11.2 on it it would detect local networks and ask if I wanted to use any of them. Since they belonged to other people and I use a wired connection at home, I declined. I then took my netbook on travels and tried to connect to freely available networks there, but to my surprise it no longer detected them. I tried to go through YAsT and see what needs to be changed but no matter what I tried the wireless option was never offered again.
I have now come back and decided to get to the bottom of this. Here is what I get from iwlist scan:lo Interface doesn't support scanning eth0 Interface doesn't support scanning.It is as if there has never been a wireless capability. Can anyone advise on what to do to fix this?
I am using an HP G60 laptop with a built in wireless NIC but am unable to get the wireless connection working. I have followed the advice in the sticky messages above and have included the information below. I know the wireless modem is working as I have got a spare USB wireless dongle running on the desktop (ironically - I can only get it working where it is not needed!!!). The same dongle will not work on the laptop. So it is a config thing and not a hardware issue On a trivial level, left clicking on the Network Manager icon shows the "enable wireless" greyed out. Desktop and laptop are running SuSE 11.3 and KDE4.4.4. I have tried the traditional method as well as knetwork manager and have no success with either. Here are the technical details.

I just installed Slackware 13.1 on my Asus 1215T, and I've been trying to get it to connect to my wireless network in my home. When I type iwconfig I get no wireless extensions, and ifconfig returns only lo, no wlan0. I read the Slackbook wiki and tried to configure the inet1.conf and wireless.conf but still no luck...
I wanna see the wifi signal strength.But when i run the command iwconfig , it tells me 'no wireless extensions'.By googling I found that I need to enable config option CONFIG_NET_RADIO.I see that this has to be done in boot which has config files.So I typed the command grep CONFIG_NET_RADIO /boot/<config-188.8.131.52-127.fc12.i686> (my fedora version is 184.108.40.206-127.fc12.i686).But I got the error as "bash: syntax error near unexpected token `newline' ".I dont know the reason.I also want to know if I have to install driver(ndiswrapper)for viewing wireless signal strength.I thought that the drivers will present default(am not sure).
Ubuntu 9.04 with working wlan. I had to restart router & wap. It doesn't seem to ever retry to connect. I know my router & wap are good, I have wireless working on other laptop (running Puppy) I had to go into 'edit connections' in drop down and use 'wireless' tab then edit 'wireless connection 1' and hit 'apply' is there a better way to do this? also, no connections show up with command 'iwconfig' edit: with ifconfig, eth1 si showing data my ip address and packets sent & rcvd. I think I'll try do duplicate this event and use 'ifconfig eth1 down' and then up again to see if it reconnects.
having trouble with my asus 1000 rt2860 wireless n card and WPA/PSK/WPA2 connections. Funky thing is it worked in the 2.26.32-21 kernel (iwconfig shows ra0 as the wireless interface), but when the kernel was updated and pushed through in the ubuntu updates to 2.26.32-22 the wireless card won't stay connected and iwconfig says wlan0 is the interface. I checked the proprietary drivers and they said that the driver for my card was active, but not in use. How do I use the ra0 instead of wlan0?
how do i use the driver that's listed as not being used? I'm having to boot up lucid with the older kernel now, it's annoying, lots of programs aren't running as expected as a result. I've tried manually installing the driver from the RaLink website as detailed in many other posts concerning this wireless card. It seems to work for some people, but not with me.
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.
left to its own devices my wireless connects at too low a speed. I have a 20meg internet connection and my wireless is slowing it down to like 3meg. When I reboot into windows it's fine. When I run iwconfig eth1 rate 11M or even 24M the connection is much faster and runs fine, why won't it automatically go higher? Is this the fault of the driver? I am running Broadcom's driver compiled from source. Also, how can I set it to 24M at boot?
Edit: I guess I can put iwconfig eth1 rate 24M in rc.local, but I'd still like to get auto running higher, especially as my signal should be pretty good. Output from iwconfig white rate=auto:
eth1 IEEE 802.11 ESSID:"honeypot" Mode:Managed Frequency:2.417 GHz Access Point: xxx Bit Rate=1 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thrff Fragment thrff Encryption keyff
In our family we have an Eee PC / in Windows7 and openSUSE 11.4 everything is working. In Mint 10 Gnome 64 and 32 bit and Fedora 14 Gnome 32 bit we don t have wireless with persistent USB. iwconfig > no wireless and Networkmanager does not show wireless.
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
I updated my system from FC13 220.127.116.11-66 to 18.104.22.168-68 for both the kernel and the kmod-wl RPM's. After doing so, iwconfig wlan0 key 1234567890 no longer works. I get an error indicating 'invalid argument'. If I reboot using the previous kernel/wl.ko module, it works The size of the wl.ko module increased in size by almost 30%. Did I somehow get the wrong RPM?
I have an Asus U52F laptop with the Intel 6050 network adapter. Code: # lspci | grep WiFi 02:00.0 Network controller: Intel Corporation WiMAX/WiFi Link 6050 Series (rev 5f)
I've downloaded the Intel firmware and dropped it into the correct location according to the README. Code: # ls -l /lib/firmware | grep iwl -rw-r--r-- 1 root root 469780 Jul 10 13:18 iwlwifi-6050-5.ucode
I am using the current module from compat-wireless. When I modprobe iwlagn, I get no error message, and the module shows up in lsmod. Code: # lsmod | grep iwlagn iwlagn 158054 0 mac80211 179615 1 iwlagn cfg80211 139799 2 iwlagn, mac80211
However, no wireless devices show as being attached to my system! Code: # iwconfig lo no wireless extensions. eth0 no wireless extensions.
I also see errors in dmesg. Code: # dmesg | tail iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: iwlagn: Copyright(c) 2003-2011 Intel Corporation iwlagn 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:02:00.0: setting latency timer to 64 pci_resource_len = 0x00002000 pci_resource_base = ffffc90016384000 HW Revision ID = 0x5F pci_enable_msi failed iwlagn 0000:02:00.0: PCI INT A disabled iwlagn: probe of 0000:02:00.0 failed with error -1
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: Entering directory `/usr/src/linux-headers-2.6.31-22-generic' /usr/src/orinoco-0.15rc4/Kbuild:8: *** Wireless extensions are not enabled. Stop.
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 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.
This is probably the 1 millionth post about WIFI issues. I have tried many sources on the internet but cant get my wireless to work. I have been using another version of linux for long time. But recent edition of that particular linux does not support my wifi any more. Just recently i have tried SuSE and almost fell in love with it. The only problem, WIFI.
I got a Linksys WUSB54GC USB wifi stick which uses RT2800USB native driver. I installed SuSE from the scratch and it found the wifi stick installed the drivers. My only problem is it does not scan for wireless networks. I haev two wifi networks around here. I can connect to them with windows computer with the same wifi stick.
I have tried iwconfig iwlist ifup but i am stuck exactly what to do.
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.
So I installed Ubuntu Server 10.10 64-bit for testing purposes. But when I went to connect it to my wireless network at home, it showed that iwconfig wasn't installed by default like it did in 10.04. Does anyone know how I can either connect my system to the network without using iwconfig, or how I can get iwconfig and install it from a flash drive or some other form of digital media? And I can't do apt-get since I can't get on my network. And I also can't plug in a ethernet cable because my network port is broken.
I have a server with 3 interfaces. Only one of them comes up after boot tho (the one with the cable plugged in). When I start dhclient the others show up in ifconfig... Could it be just cause there is no cable plugged in them? Or then how do i bring them up automatically without having to issue dhclient myself after boot?
I recently installed the XFCE spin of Debian (amd64) on my Lenovo L440. I tried installing it before, but apparently the 3.2 kernel that ships with Wheezy doesn't properly support the proprietary firmware for the wireless card, blah blah. So I wound up using Windows 8.1 for a bit, and then Fedora (boo). Anyway, with the wheezy-backports kernel (3.16.7-ckt4-3~bpo70+1) everything works like a charm. Everything, that is, apart from the sound card — the entire system is completely mute. Well, apart from the system beeper. I searched the forum and found another thread, but that guy was (for some reason) just running dwm — I figured XFCE might feature a more complete sound system. But maybe the output he gave will be useful in my case as well:
I have two simultaneous active mobile connections through my two mobile phones and USB data cables. Yet I can only send/receive with one connection.
Each of the phone modems have a node in /dev, namely ttyACM0 and ttyACM0. So the modems are detected correctly. After setting up two dial-up connections with the two modems I have two ip's. Ifconfig-a confirms this:
