Fedora Networking :: Dhclient Wlan0 - After Logoff Network Is Gone
Apr 30, 2010
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!
Having trouble with wireless and FC11, eth0 is ok. When I try to activate wlan0 through system-config-network 1.5.97, I get msg: Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0... failed. This is a compaq laptop.
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 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
I am running Fedora 13 and after my machine is booted my ethernet interface eth0 does not have an IP address. Running
At the terminal does not work, and I can see that in /var/log/messages I have the following error:
I assume that the same command was attempted during the boot process (please correct me if I am wrong) to use DHCP to get an address for eth0, but failed for the same reason it is failing after boot when I run it manually, whatever that reason may be.
I noted, however, that eth0 IS in broadcast mode:
I also noted that running
Does in fact work and will run DHCP and configure eth0 with an ip address.
It is quite mysterious to me why running 'dhclient eth0' will work, but manually running 'dhclient' does not.
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 got a full system crash each time I try to do anything with network. Been fighting with this problem for weeks now. What I did: -tried every driver for broadcom4312 and it turned out that it even crashes with cable net
-got rid of networkmanager ( Mar 11 08:01:43 geburah NetworkManager: <info> Activation (eth1) successful, device activated. Mar 11 08:01:43 geburah NetworkManager: <info> Activation (eth1) Stage 5 of 5 (IP Configure Commit) complete. ) used: ifconfig eth1 up
I have just installled fedora, and I am puzzled by dhclient-script. Because it gives the router ip as nameserver 192.168.0.1. I have had other linux distro on same machine that resolves the correct nameserver without any configuring.
Does anyone know how to get your ISP:s nameservers instead in /etc/resolv.conf when running dhclient from CLI? I have thought about edit /sbin/dhclient-script. But if that is the case. Which option should I edit?

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 Version: 01 Width: 64 bits Clock: 33MHz Capabilities: bus_master cap_list Configuration: driver=b43-pci-bridge latency=0 Resources: irq:17 memory:f69fc000-f69fffff *-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 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 am tring to get my linksys wireless router to connect to my laptop that i recently installed Fedora 10 on. Well it is actully running of an external HD. Any way when i boot in windows it connects and works fine, but when i try to activate wlan0 it says "Cannot activate network divice wlan0!" "determining IP info failed..."
The past couple days I've been attempting to use ndiswrapper to connect to my home network wirelessly and have run into a slight problem. I'm able to install ndiswrapper (of course), and install the driver. ndiswrapper -l comes up good, showing the driver is in place for my netgear wg311v3 card.
modprobe ndiswrapper I am able to get to work without errors, except, when i type ndiswrapper -ma it writes another file to /etc/modeprobe.d/ndiswrapper causing the deprecation error.
The card scans for networks, and I'm able type in my encryption key.
However it doesn't connect. | grep comes up with the error that the wlan0 link is not ready.
I think I've also been able to determine that the configuration I've put in to the card through the network manager is not actually configured.
Anyone know how I could possibly connect with the card.. It seems it should be able to work. alias wlano is also in place.
I've been able to get a laptop on Fedora 14 (126.96.36.199-48) working with a Netgear WNA1100 Once up and running, I execute "ifconfig wlan0 up" from root, and everything connects just fine and is stable as long as I stay logged in. But, I haven't found how to do this automatically on boot.
I've tried to use NetworkManager, but I cannot figure out how to get the GUI to show up - it says its running and enabled in the Services gui, but I haven't figured out how to actually use it! I checked to see if the nm-applet is running with ps, and for the user login, I see:
I'm not sure if the "sm-disable" flag is my problem, or how to change it. I'm not even sure if NetworkManager will allow me to set things up for bootup, but that is the path I ran down...
I assume this is a fundamentally easy process to set this up on bootup, but I'm not stumbling across the method. I recall doing this kind of thing years ago when I was an engineer, and before I got my lobotomy to become a manager...
i can't get a pppoe conection working over a wireless network,in windows I have to connect to the router first, and then put in my user and password to get connected, but i don't know how to do this on fedora, i get connected to the router through network manager, and ping is ok, but when i try to make a new xDSL connection i don't know how to make it work through the wireless network that is established and working with my router.
I am having a problem trying to transfer large file (~700MB) from one station in my home to another. I have 3 PCs hooked up through a router. 1 is wired to the router and the other two are wireless. One wireless is a laptop that has a built-in Atheros wireless card that was supported during the FC13 install. The other wireless has a plug-in wireless card made by Belkin (F7D1101). I had to use ndiswrapper to get it to work on FC13.(BTW all PCs are running FC13)
The one with the Belkin card is, I think, the problem. The one with the Atheros card will transfer files at a rate of about 8MB/sec to the one with the wired ethernet connection. The one with the Belkin card will not transfer at rates over 300KB/sec to either of the other two PCs. I have tried file transfers both encrypted and not and it makes no difference.
I'm new to this forum site and I was wondering how can I bridge a network between the eth0 and wlan0 connections?my eth0 NIC is a RealTek RTL8111B 10/100/1000 Ethernet Card (OnBoard) and my wlan0 NIC is a RealTek RTL8187B 802.11b/g WiFi USB Adapter Card.Are there any utilities, such as bridge-utils that I can use, except for Firestarter since Firestarter states that the eth0 connection is not established, or do I right-click on the network icon and select Edit Connections and go to Auto eth0 and under the IPv4 Address setting and select Shared to other computers and run a live connection there?The main reason is that I need an Internet connection for my Xbox 360, which is connected to my Linksys WRT54G 802.11b/g Wireless Router, that has DD-WRT firmware installed and 4 WiFi hotspots for any wireless device, such as my PSP, DS, DS Lite, Wii, Laptop(s), my brother's PC (needs a WiFi card), and my dad's PC (needs either a WiFi card or an Internet connection from my brother's computer to my dad's PC)
Here are my Computer Specs: ECS nForce6m-a Motherboard 2GB DDR-800 PC6400 Memory
Since 188.8.131.52-170.2.35.fc10.x86_64, dhclient wlan0 doesn't seem to work any more.
However, bizarrely, dhclient eth0 does (to the same D-link wireless router).
The AP shows connected - tail /var/log/messages
No working leases in persistent database - sleeping.
WINXP connects just fine. This (B43) has worked nicely ever since FC10 came out, and I was able to use the WiFi at all kinds of places on a recent trip. Other than a couple of yum updates, I don't think anything else has changed since. Other devices on the wlan are getting their DHCP requests satisfied correctly.
Is anyone else having this problem since about a week ago? Perhaps there's something really obvious I'm missing. I can manually assign an IP address to wlan0, manually edit the routing tables and edit /etc/resolv.conf, and then Wifi seems to work OK, so it doesn't seem to be b43 itself unless it is dropping DHCPOFFERS. If this isn't a regression, does anyone have any tips about how to debug this?
client <--> wlan0 <--> computer <--> eth0 <--> internet
i have 2 network connections eth0 wired connected to internet wlan0 wireless (work fine) i have installed hostapd with madwifi and so on oki when i run hostapd the clients see the hot spot oki clients connect with wpa oki network manager run at demand not automatic (keep it for internet help) now i'm a bit lost what do i need is wlan0 give the client an ip (dhcp demand) create a bridge between wlan0 and eth0 steps to create a permanent bridge between wlan0 and eth0
I have setup hostapd and a bridged setup with br0 bridging eth0 and wlan0. The setup works but unfortunately not on bootup. The reason is that the bridge can't add iface wlan0 because it is down for some reason at this time. When hostapd is running (after the network script) the interface is up and can be added to bridge via
Just installed f14 on my Toshiba laptop, which has a realtek ethernet card. i installed the drivers from the realtek site with no issues (also, i know the card is good, i had it working on suse a while back). No matter what I try, i cannot seem to get the computer to recognize there being a wireless connection (tells me no such thing as wlan0).ifconfig shows the following:
Code: # ifconfig eth0 Link encap:Ethernet HWaddr 88:AE:1D:F4:AD:88
While i am configuring network setting on backtrack4. i was running my backtrack on vmware workstation and NAT is bridged to physical mem like it was said on the tutorial that watched. i typed ifconfig eth0 up, and hit enter, as well as dhclient eth0 up, but resulted in different output. it says "no such device" is written and i would like to configre this problem.
