Fedora :: Run The Command Iwconfig It Tells 'no Wireless Extensions'
Apr 9, 2010
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-2.6.31.5-127.fc12.i686> (my fedora version is 2.6.31.5-127.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).

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...

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 installed SATA driver recently...Even if i can use wifi but i could'nt find any ath0 interface in ifconfig or iwconfig commands....My wifi is taking place through eth1 interface why it happens.....The reason for asking this in order to use aircrack for wep key it says that the injection process only applicable for Athelon interfaces but mine is eth1...I was just trying aircrack-ng...

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.

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?
Here is an output from iwconfig on my system:

A friend of mine have just migrated to Linux, and as recommended by me, He's trying Fedora 15 KDE. Everything runs just fine, he loved the OS, but there's a sad problem, his network card seems to have no "wireless extensions", which makes the system impracticable to use. I've tried searching around which card JMC250 is a single-chip PCI-Express Gigabit Ethernet Controller
with lspci
and which driver for this card
JME
is installed, with modprobe list
I've tried loading this driver with modprobe jme, no errors. And I've also tried compiling a driver I got from the manufacturer. No changes.

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.

I was running an update on my computer (running Ubuntu 10.04 Lucid) and something must have been transferred incorrectly as every time I open synaptic, I get an error message that tells me to type a command into the terminal:

After doing that, it displays this:

Unfortunately, when I try to install Debian off the DVD, the wireless gets disconnected right when it tells me to choose my method of connecting to the net. It then gives me three choices of connecting - wired, unknown, and wireless. I must be missing something, because when I choose wireless, it says it fails, and cannot find anything to connect to. I input the SSID and password manually and it says its not there. So I quit the install and go back to the desktop and reconnect no problems.

I am trying to connect to a wireless network. I got a problem with network manager. So I try to connect manually
I found wireless network around by using "iwlist scan" command.
I want to connect to a network with ESSID "MCC(Mandalay)" and Key "mdymcctraining"
Here is my problem The output of "iwconfig" command is
Code:
What does it mean "invalid argument"? It means that my wireless pre-sharedkey is not correct? I am sure the key is valid. It is used by any others with window 7.

I've beenhaving some trouble getting my wireless network card working on my Slackware 12 box. Currently it identifies the card and can scan for networks, but I can't seem to join a network. Here's some output:
{8:46:29}gibson:/lib/modules/2.6.33.4-smp## iwlist wlan0 scan
wlan0 Scan completed :
Cell 01 - Address: F8:1E:DF:FF:DA:39
ESSID:"MasterControl"
[code]....
It doesn't seem to be accepting the essid setting, and it's giving an error for the key setting. Also, I'm noticing an inconsistency in the wireless protocols. The AP claims that it's 802.11g with rates up to 54 Mb/s. But it should be 802.11n. It's an Apple Airport Extreme and the Radio Mode is set to Automatic and displays "802.11a/n-02.11b/g/n" on the Airport Utility. The interface also claims that it's 802.11g, though shows a rate of 300 Mb/s. It's a Belkin "Play" Wireless USB Adapter (F7D4101).
(Note: I'm using ndiswrapper and the WinXP drivers which were installed from the Belkin software.)

I still cannot access to internet. May I know why?
Is it due to the Error for wireless request "Set Encode" (8B2A)
The step i did:
1) iwlist eth1 scanning
2) sudo iwconfig eth1 essid shabana key s:xxxxxx
3) invoke firefox ... cannot surf
Do I need to set dhclient? how should I set? DO I need to enable wpa_supplicant?
iwlist eth1 scanning
sound like I was able to connect to ESSID:shabana. Is it true?
The linux is Centos 5.4

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

I have a directory of a load of files without extensions. I know what the filetype should be, so is there any way of batch renaming the files to append a given extension onto it. i.e. text would be renamed as text.txt?

Im actually using Fedora 11 in Dual Boot with VistaI used to have Fedora 11 and then I installed Ubuntu and it (and myself) screwed my partitioning, and Just linux used to run.Ubuntu wrote the boot sector over the NTFS like it was ext3.I tryed everything the get beck my windows partition booting.Reinstalled a Fedora 11 clean, to see if it could help me (thinking in reintstall it later).Using testdisk application I managed to have back access to my disks files, but no boot working. I tryed a lot of things in testdisk and Windows Vista Recorvery, with no work.
So I ran the Acer Recorvery Disks, that reseted my NTFS with Vista to a brand new installation from Acer.Now I want a Full Fresh Fedora Install from DVD but anaconda tells me (in pt-br): "Error in processing the disk sda. Maybe it would be necessary to reinitialize. YOU WILL LOOSE AL THE DATA IN THIS DISK."I really cannot reinitalize it becouse my NB have some recorvery partitions that I use to reinstall the windows to its factory settings, and Im scared of reinitalizing it becouse maybe it could just screw everything and make it not work as well, now with no OS running.The GNOME Partitioning Software just detect a full unpartitioned hard drive. I think the problem is that I changed the LVM to something wierd that anaconda dosent recognizes.Some hardware information (my fedora is in PT-BR):Quote:

I installed it and all works great except there are no active wireless extensions.My laptop have an internal wifi adapter (bcm43xx) I tried to load that driver using legacy OS network wizard but didnt work, the other is a external wireless card with a rtl8187 driver, this last one is the one I want to be up. I also tried to use ndiswrapper but can't set it up either.

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.

Just bought a netbook, ASUS Eee PC 1001PX, and got rid of the crappy XP pre-installed. first i put netbook remix on it, and tried many downloads and ndiswrapper to fix the wireless problem. then i went ahead and put another form of ubuntu on it thinking it might have the right drivers need to use the built-in wireless card, nothing. i dl all updates and bug fixes. i went to atheros to download the only driver they have for linux in the AR8132 class but still not helping. although i am not sure if i even installed. once dl it only extracted itself. i couldnt figure out how to run. if someone has this type of netbook it would be awesome. everything works on it except wireless and headphone jack. i know its just cosmetics but it would be nice if all hardware worked.
