I just added a 2 port network card to a system that is running Fedora 11, but it is INACTIVE. I open the Network Device Control to activate it but there is no network ports in Network Device Control. It is empty.It looks like the system recognize the card and loaded correct driver.

I just brought up FC12 on our VSphere to begin testing..The nic did not configure properly for some reason.. I was able to go to command line, and do an "ifup ifcfg-eth0" and DHCP got an address. Go into GNOME - System-Administration - Network , or system-config-network the "Activate/Deactivate" is greyed out. Also, GNOME - System-Administration - Network Device Control show NO device..

I just did a clean install and ran system-config-network from command line to fix my IP settings. Everything works but when I reboot, my NIC is gone from #ifconfig -a
I have to login to the GUI and go to System --> Administration --> Network --> "Click on my NIC" --> check the box that says "Activate device when computer starts"
Once this box is checked, everything works fine. - I have turned off NetworkManager and just use the network service to manage my ip settings.
I was wondering if this "Activate device when computer starts" can be done through the command line without having to access the GUI?

The problem I'm having is on a CentOS4 machine. I don't use CentOS regularly (Ubuntu and Mint, yes) so I'm not sure if this is something that is particular to CentOS or not. I have this workstation that controls a microscope controller. The drives in this computer are some POS Seagate drives where the data storage drive has already conked out more than once. I think this time there was a problem with the OS drive that caused a lot of filesystem errors. I wasn't able to boot the OS at first but I ran fsck from a liveCD and was able to fix the (hundreds of) errors and the OS can now boot from the drive. The problem ave now is the ethernet does not work. I know there's not a problem with the ethernet controllers because I can access the internet through the liveCD. When I try to activate eth0, or eth1, I get the following error:Quote:
Cannot activate network device eth0!
network-functions: line 180: ip: command not found
WARNING: /lib/modules/2.6.9-89.0.9.ELsmp/modules.symbols line 1: ignoring bad line starting with 'GROUP'

Code:
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!

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 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've been running F10 since it first came out, and I was happy to see it was the first Fedora release that automatically recognized my Atheros wireless card. I have to run system-config-network and press the "activate" button when I start the machine, but that's ok and no big deal. But today, for whatever reason,in system-config-network, the "activate" and "deactivate" buttons are grayed out and I cannot start the device so I have no network access. When I boot the machine into Windows, it works fine.

I installed Fedora 11 last night, and it seemed to go OK. The trouble is, I cannot get a wireless connection to the internet. The system seems to recognize my wireless USB adapter, but the buttons to activate the device remain grayed-out no matter what I try. I ran through all of the steps in the help menu (still grayed-out); I tried deleting and adding the device (no go); I tried to run the installation disk that came with the USB adapter (wouldn't run); I pulled the drivers off of the installation disk (Fedora couldn't recognize the file type); I changed it from "wlan" to "eth0" to "eth1"... but still no love!
This doesn't seem like a problem between the adapter and the router... the USB adapter and my PC can see each other, but can't "talk" to each other.
Info:
PC - Dell Optiplex GX50 (circa 2001)
OS - Fedora 11
USB adapter - Linksys WUSB54GC
Wireless Router - Linksys WRT54G (reflashed with dd.wrt)

Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig

I have downloaded and installed Fedora 10.Now I am setting up the network and in the 'network configuration' it finds the wireless device (ralink) in the 'hardware' section of the configuration - I set this to eth0 (it originally set itself to wan0 and I still had the same problems, now it doesn't give me the option to put it back to wan0).Now I goto the devices tab and try to set up the device with eth0 - which it seems to find.But when I goto activate the device it tells me that eth0 cannot be found

I had installed Fedora 12. I am using 4 LAN Cards. All these cards were configured using network manager, but i am not able to acivate /deactivate these cards using acivate /deactivate buttons since they got disabled. I could activate the cards by running /etc/init.d/restart network. Anyone knows why the acivate /deactivate buttons in network manager are disabled .

I have a desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.

I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?

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 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

Clock: 33MHz
Capabilities: bus_master cap_list
Configuration: driver=b43-pci-bridge latency=0

*-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.

New to ubuntu. I love the OS. Everything works great except for the network connection. It tells me I need to activate the b43 drivers with fwcutter, but here are the following problems:
1) I can't download and install the drivers b/c I can't connect to the internet wired or wireless.
2) I can't find the website to download the appropriate drivers (I've looked for hours)
3)I'm not too sure how to install them since I don't have a background in coding.
I really like ubuntu, I just need network working.

My Network manager is missing (it is usually has a short-cut on the desktop-bar, which are monitor pictures, next to the sound short-cut). Does anybody know how to activate it again (terminal-based command or etc)? See my attachment, i made a circle sign on the missing network-manager.

I have installed a new network multifunctional device Samsung CLX-3185FN using the drivers provided by the manufacturer (Samsung Unified Driver). The printing over the network works fine, I can administer the device using browser. The only problem I have is using scanner over the network. It works fine if I disable firewall, but is blocked with firewall enabled. I can not figure out which ports or port-range I must enable for this scanner. Do you have any information on this one or how can I found out the necessary ports to open?

Installed Fedora 11 yesterday and was trying to use the Admin->Software Update but initially it complained about no connectivity (this is happening even though I was able to browse the web via FireFox!). So I went to Admin -> Services, and restart the Network Manager. It was then able to download about 250 updates. However, when I clicked on Install after the download, it says it was disconnected. When I went into Admin->Networking, I found out that the eth0 interface is Inactive. However, the Activate button is greyed out. I have been searching in the User Guide, the FAQ, the bugs section and have been unable to find out how to fix this. If I goto the command prompt, and typed in "ifconfig" I can also see that there is no IP and no packets transferred.

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.
