Fedora Networking :: Ifconfig And Iwconfig See Wlan0 But Network Manager Does Not
Aug 22, 2010
I just installed Fedora 13 from the Live CD. FIrst off I read the guide and the first step doesn't even work for me. System>Administration>Network does not exist. If I go to System then Preferences I see a Network Manager but it looks nothing like what these screen shots look like. [url]
No wireless card show up in the wireless tab of Network Manager. How can I fix this since my card is listed in ifconfig and iwconfig. Wifi card is a Zonet zew2500p

When I try to bring up my wi-fi PCI card (ifup wlan0 or ifconfig wlan0 up) my whole PC just hangs until I power it off.
I believe I have the right drivers, but cannot see what I am doing wrong.
I'd really prefer not to go down the ndiswrapper route.
Firstly, I can see the PCI card and the driver it is using :
Code:
[J@gx260-f10 ~]$ lspci -k
...
...
01:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller (rev 20)
[Code]....
the PC just hangs for ever. No mouse movement, ctrl-alt-del, nothing.
I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.

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

*-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 can connect to the wireless at my school, but the connection drops frequently and regularly. Network Manager still shows bars indicating the network strength and shows that it's connected to the network in the dropdown. Selecting the network again causes it to indicate that it disconnects and reconnects. At this point I have wireless until the connection drops again. Possibly relevant details: This is the Purdue PAL2.0 network, which can be tricky to connect to, particularly for Linux users. It's a hidden network using WPA2 and PEAP. My computer is a Dell Inspiron 1420n laptop, circa August 2007.

I installed squeeze on my eeepc 1015ped and downloaded the correct firmware-brcm80211 drivers but every time I scan for my network using iwconfig wlan0 scan or wicd, my computer completely freezes. I previously had a solid install running xmonad, and wicd was working like a charm (using the same broadcom driver) but i tinkered too much with it and decided to do a fresh install. I haven't quite run into a problem like this before.

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.

I've been trying now for 2 days to get my WUSB600N v1 adapter installed on 10.04. I'm a bit of a noob but have been able to follow some posts on here on getting it set up. This is what I've done:
Installed the Ralink RT2870 drivers. Changed the config.mk to enable some parameters. Compiled and installed. Added some entries to blacklist.conf. Updated network/interfaces to include my wpa settings and passphrase. Restarted/rebooted/reinstalled about 100 times!
Here's what happens: iwconfig shows wlan0 with an ESSID:"" and Nickname: "RT2870STA" iwlist wlan0 scan shows my router fine (although does not show Cell 02 which should be the 5GHZ range). So basically it's not connecting to my router. Not sure if I missed any steps. Will gladly provide some extra output if needed. Pulling my hair out over this now ready to throw the adapter in the trash.

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

I just installed Ubuntu 10.04 on a my laptop with a built-in wireless card. I also installed drivers using "ndiswrapper", but I can't make the card work.
When I type "iwconfig" in the Terminal, I don't have the wlan0 listed. In the wireless network drivers, I see the driver I installed and it says: "Hardware present: Yes"

I have recently converted my old desktop computer into a server (using the ubuntu server 10.10 install disk), installed xubuntu, and have installed the driver for my WPN111 usb antenna using ndiswrapper. I then installed wicd to connect to my home network (with a WPA2 passkey). Anyways, it works great... with one major annoyance � whenever I reboot (with "sudo reboot") the computer, the wireless configuration isn't detected at all.
Code:
$ iwconfig
lo no wireless extensions
eth0 no wireless extensions
The only time it works is when I turn my computer off and manually turn back it on... and then "iwconfig" gives me a third entry: wlan0. The wireless then (and only then) works like a charm. The problem is, I want to be able to access this server away from home, and of course in that situation I cannot manually reboot it.

I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,

I recently installed fedora 12 in my server where I had a page published in my local net by tomcat, and I was looking on the Internet how to set up an static ip address and this is what I did
on /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express
#
# File: ifcfg-eth0
[code]....
then I can access via ssh by two addresses the one I got from dhcp (10.17.148.223) and the static one (10.17.148.26) I put ifconfig and and 10.17.148.223 appear on eth0 I restart my server and I just can access from 10.17.148.223 I have to put
ifdown eth0
ifup eth0
Again...to access by my static ip, y can access my page by its dns on my server, but I cant access from other computer...so, I guess when my static adress appears on ifconfig I would be able to access my page from other computer...

I have a laptop with Ubuntu 11.04. Failed to connect my home wireless network, which is composed of a modem and a Netgear router.
ifconfig showing:
wlan0 Link encap:Ethernet HWaddr 00:24:d6:07:2b:a2
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:30238 errors:0 dropped:0 overruns:0 frame:0
TX packets:24005 errors:0 dropped:0 overruns:0 carrier:0
[Code]....
I do not quite understand how the virtual interface wlan0:avahi appeared. My guess was, my request "sudo dhclient wlan0" failed to get a valid ip, although I did not get any error message from running that command. I executed "sudo dhclient wlan0" again, but still no error message or network connection.
Later today, I tried to connect to a public wireless network. Still got the same error. But when I reboot my machine, no such problems.

I'm running fedora 8 and i have a TEW-424ub. I recently ditched windows, and the only disk i could get was a Fedora 8 dvd. I used ndiswrapper to get my driver installed, then I used the iwconfig commands to hook myself up to my wireless. However, every time i do the command
Code:
My comp freezes up. I then decided to use the GUI to set it up, as it might be less aggravating. It found my network, i input the key, double-check, and it atttempts to connect, then asks me once again.'
Also, if I go to Network Configuration, and activate my ndiswrapper device, it gives me the error & my comp freezes up "Set Encode" (8B2A) SET failed on device wlan0:0 ; Invalid argument.

I updated my FC10 just a day back. The problem is that Netwrok Manager has disappeared. And in spite of re-installing it, it doesn't appear on the panel when i enter 'NetworkManager' as root in the terminal.I have a USB modem right now. Update was made through a broadband connection. Ethernet works perfectly well but this USB modem of mine doesn't work at all. And I have to use USB not Ethernet.

I have got DHCP issues with Network Manager. Whenever I try to connect using static IP it works, but when I use use Netowork Manager with DHCP, it seems to try to connect and soon says "Network Disconnected"..I've managed to connect to wlan and eth using network, so there shouldn't be any hardware/driver issue.

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:

I just installed Fedora 13 on a new Dell XPS desktop and some of the networking files are not created/missing. The computer has Broadcom Gigabit wired card and Asus PCE-N13 wireless card. When I type lspci, I see that Network conroller: RaLink RT2860 and Ethernet controller: Broadcom BCM57780 Gigabit Ethernet. So, somehow they are being detected by the OS, but I am not sure if the drivers are installed or why some of the network files are missng.

I have run Fedora 9 and 10 on my Dell Inspiron 640m for about 6 months now and generally experience very few issues with it. Specifically I've been running Fedora 10 KDE 64bit since it was launched. Up until I had to reload it a couple of weeks ago my Vodafone Huawei E172 3G dongle worked perfectly with Network Manager. Since the reload the dongle is detected by the OS (lsusb lists it correctly, etc) but nothing I do will make it appear in Network Manager.
I've tried manually configuring a GSM connection then plugging it in, but no joy. I've also tried using it in my Acer Aspire One which runs Fedora 10 XFCE and it work, but when I try it in another Dell Laptop running Fedora 10 KDE 64 bit it doesn't. I'm assuming that a recent update must have caused some issue as it has definitely worked in both Dell laptops in the past. As mentioned I've reloaded recently but the other laptop hasn't been.
I'm unsure where to go from here. I haven't been able to get Vodafone's beta drivers working under F10 (although I did under F9) and can't find any posts on this issue. The version of Network Manager that I'm running is NetworkManager-0.7.0-1.git20090102.fc10.src.rpm, which was released shortly before I reloaded. Chances are I just didn't try my dongle between the update coming out and the reload, so didn't notice the problem before hand.

I'm running Fedora 10. My Network Manager settings are all grayed out. They are uneditable. I can see the detected settings, but not change them. All of the settings fields are disabled.
Is there a way to enable these, so that they can be edited?
Starting with the menu in the upper left corner of the GNOME screen: System/Preferences/Internet And Network/Network Connections
The Network Manager window appears correctly.
I see all automatically generated settings that were created for my various devices:
In particular, I want to be able to edit "Auto vmnet8", for VMware usage.
I know about the workaround of going back to the manual network configuration as used in older versions of Fedora, such as editing the files in /etc/sysconfig/network-scripts/ifcfg-* and then enabling the old "network" service and disabling the "NetworkManager" service.
However, this workaround really won't work in this situation. The VMware interfaces, vmnet1 and vmnet8, are virtual interfaces that *only* exist when the VMware services are running. The VMware services are started *after* the old manual network configuration would be applied. So, at the time the scripts in /etc/sysconfig/network-scripts are processed, the vmnet1 and vmnet8 devices do not yet exist! I'm hesitant to change the numbering of services, lest other things break (VMware on Fedora 10 is rather fragile already).
I love the feature of NetworkManager to be able to automatically apply settings to newly materialized network devices (such as vmnet1 and vmnet8 when VMware is loaded). However, I need to also be able to edit those settings.
Is there a solution that will make my Network Manager "Edit" window not be entirely grayed out? I can see the settings pages just fine, but unfortunately, they are all disabled and I can't edit them at all.

I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.
