Commands as root works well when normal user is logged in and connected to net via KDE 4 network manager, but after logoff network is gone. And it is impossible to get it back because command mentioned above stops working!
I can't seem to figure out how to solve my problem. I have a HP Mini 1100 and I can't seem to get wireless working. As the title says, when I type ifconfig wlan0 up I get the SIOCSIFFLAG: No such file or directory error. wlan0 is listed in the output of ifconfig -all. Here is the output of lspci and lsmod:
Total size: 821 k Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Finished Transaction Test
Transaction Check Error: file /usr/share/man/man5/dhcp-eval.5.gz from install of dhcp-12:4.1.1-5.fc12.i686 conflicts with file from package dhclient-12:4.1.0p1-17.fc12.i686 file /usr/share/man/man5/dhcp-options.5.gz from install of dhcp-12:4.1.1-5.fc12.i686 conflicts with file from package dhclient-12:4.1.0p1-17.fc12.i686
And I see that if I uninstall the dhclient package, I will lose my networkmanager, which I also need, is there a way to have a dhcp server as well as dhclient utility on fedora as it is possible on rhel?
i wanted to learn linux, so i just installed Centos on a thinkpad x200. my wireless will not work. when i try to activate it i get this error:
Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory SIOCSIFFLAGS: No such file or directory # lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
(and new-ish to Linux in general) and would appreciate some assistance with fixing a problem I'm having with getting wireless working on my computer.Computer specs: Lenovo Thinkpad Edge 520, I5Wireless card: Intel WiFi Link 1000 b/g/n(Note: I also have a Netgear USB wireless adapter, and trying to use this does not solve my problem)I cannot activate wireless. When I go to Network Settings > Wireless, it is listed as "unavailable", and "off". When I try to switch wireless "on", it says "disconnected", but then immediately switches back to "off".Having tried to browse various forums and such for a solution, I tried looking for the file ifcfg-wlan0 under /etc/sysconfig/network-scripts, but it doesn't exist
I have two usb wlan cards. In 11.2 whenever i start connection with the second one (wlan1) via knetworkmanager, the latter also starts a connection using the first one , leading to wlan problems,
In 11.1 i had no such problems because i could select the one to be used in knetworkmanager, and only that one was used by knetworkmanager.my current solution is to
su ifdown wlan0 logout
this shuts down the first card but i have to do this manually after every restart. one thing: don't come with "deactivate in bios" - i knoe this but playing around in bios everytime i switch between windows and linux is no option. So how can i prohibit permanently that knetworkmanager uses the first one (wlan0)? putting in some place of suseconfigs a rmmod <driver>? where? /etc/sysconfig ??
I have to use ndiswrapper to get my wireless card to work (Cheap D-link usb wireless). I have never had a problem in ubuntu releases with getting it up and going, but in Fedora and now Opensuse I am struggling. I have everything setup with no errors. Ndiswrapper lists my drivers as installed and my hardware present. lsusb also has it listed. but when I modprobe ndiswrapper, I am getting no errors, but I am also not getting wlan0 to show when using iwconfig. I also noticed when modprobed the wireless card's light isn't coming on like ubuntu.
I've just a had laptop meltdown which resulted in the acquisition of a replacement (HP635) sporting a realtek wireless NIC. Found the drivers and installed them and all is well. HOWEVER, the card is not activated on wake from sleep mode. This is kind of astounding to me. Every crappy windows version that I've used can handle this situation. Many searches, however have failed to yield any help. After every resume from sleep mode I have to run ifup to start wlan0. Surely this is not the only way it can be? I have to assume that I'm not getting something simple, and someone here can point out my failing. or if you can just sympathize. running 11.4 here using the realtek 8192 driver set to start at boot time. Though none of the other settings have had any effect on this problem.
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.
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 just did a fresh install of 11.2 on my Thinkpad (previously running 11.1) and am having trouble with getting wifi to work properly. My wireless will not connect reliably. Sometimes it connects after reboot but then drops and will not reconnect. Below in line 4 of the status query you can see that it says DHCP4 client NOT running.

I am having a problem while connecting to a D-Link Access Point with Multiple ESSID. It keeps saying activating but in the end nothing. I am using KnetworkManager & there is no Encryption on the Access Point.I am able to get connected with another machine using windows.Here is my hardware info:

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.
first: PXE flawless bind to dhcp address but put next binding state to free second: when installer calls init script to reinit ethernet driver (e1000 (vmware)) binding fails 11.2 opensuse fail to reinit dhcp with log entry "no free leases" third: when manual set network install works how to preserve dhcp lease on reinit of driver?
I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4 openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108 openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67 openSUSE11232CL1 dhclient: send_packet: Network is unreachable openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0 eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
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 looked into the handbook,googled for it,but found no working solution to this "problem". Everytime I use Opensuse I must su and then type dhclient,how can I make sure my connection will be up as soon as I log in?
Earlier on my wireless is attached as eth1 and it works on to load conky except the Network section is blank. After that I had renamed eth1 to wlan0 and checked at ifconfig it is working fine.Now the conky won't load and I think something to do with my wlan0.
