Ubuntu :: ESSID Configuration - Wireless Network With Static IP
Apr 3, 2011
The wireless network on my laptop is configured with a static IP. (not using nm). When I take the laptop out of the range of my wireless router the essid is becoming off/any therefore when I'm back in range the connection is not reestablished and to re-enable the connection I gotta do "iwconfig wlan0 essid <essid name>" otherwise there is no connection. Make sure that essid stays configured unless I manually want to change it?

I have a CentOS 5.5 server running currently with a Netgear gigabit ethernet card and for wifi I have a wi-fi card with the chipset: RT2860.Now I have gotten the ethernet card and wi-fi card working but my main question is: How do you bridge the connection between the ethernet card and the wi-fi card to create a wireless network with a hidden ESSID if possible and WPA encryption? (So the server basically acts as a wireless router as well as doing all the other stuff I need to do on it).

setup my static network connection Here are my details :
IP : 172.16.152.137
Subnet : 255.255.255.192
Gateway : 172.16.152.191
Primary DNS : 172.16.0.1
[code]....
but after this setup when i restart my network #service network restart while bringing up the eth0 the following message is displayed before [OK] - RTNETLINK answers : Invalid Argument now it seems either this setup is wrong or not sufficient to set up the connection, whenever i try to ping 172.16.0.1 it showing connect : Network is Unreachable

I have a desktop PC with CentOS 5 installed, and a wireless card that's working well via NetworkManager.
How would I configure the wireless card statically, e. g. by editing /etc/sysconfig/network-scripts/ifcfg-wlan0?
This would be something like :
DEVICE=wlan0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.1.252
NETMASK=255.255.255.0
ESSID=my_essid
CHANNEL=3
But I don't know how to define the WEP key here.

I moved to static Ip method for my laptop. I edited the interfaces file and it seems to work since I am writing this message from that laptop, but I have a new problem with my Debian. The mounts are not mounted during the startup anymore. Before I was using the network manager method and the nerwork mounts were all fine. Now with this method, they are not mounted and I need to mount them by firing "sudo mount -a" manually.

I have one desktop PC I'd like to use as a jukebox. It's installed in the basement as a black box, with only SSH access, and it has got a minimal CentOS 5.3 install with MPD and NCMPC. It's connected to the hi-fi in the basement, so I can stream music to it when I'm downstairs. Since I didn't want to use cables everywhere, I bought a PCI wireless card, with a RT2561 chip.
Until recently this card worked OK with Linux. Recent kernel version even have out-of-the-box support for it, except of course you still have to download the firmware from the Ralinktech website.
I gave the thing a static IP configuration by editing /etc/sysconfig/network-scripts/ifcfg-wlan0, interface went up fine, I can ping the machine and SSH into it OK. Now the only problem is, when I do a shutdown -h now, the machine "hangs" while trying to bring wlan0 down. (In case you wonder: I temporarily attached a monitor to it, since wanting to know what goes on while shutting down in an SSH session is a chicken-and-egg situation :)). I actually have to hard-reboot it (by pressing RESET).

I want my Ubuntu desktop to have a static ip-address, i have altered the interfaces file to the below and also filled the info regarding my wireless network card but still every time I reboot the desktop gets the ip 10.42.43.1, HOW is that possible???
I use a apple time capsule router, I want my desktop to run a apache server thats why I need the static ip. I also want the static ip to be set on the wireless network interface. I have an old laptop with an internal Intel pro 2200 card so there should not be a driver problem.
This i my interfaces config code...
To be on the sure side to get this to work I have configured my router(DHCP) to give my wireless-HWaddress the ip of 10.0.1.15, STILL the ubuntu desktop starts with the false address above.

I want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4
IP Address: 192.168.1.6 (This is the item I wanted to change and make static)
Broadcast Address: 192.168.1.255
Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections"
3. I selected the wireless tab and then the wireless network I wanted to edit
4. I clicked on the edit button and then I clicked on the IPv4 settings tab.
5. I changed method from Automatic (DHCP) to Manual
[code]....

I had a wireless connection to open suse from last year. I then had a problem with my Netgear 824 router.
I have reconnected to windows vista. Now I have to get opensuse working on wireless. I do not have much experience in opensuse I have read the forums and the sticky and also from wicd forums. I have checked the yast settings and it is for AR242x ath0 and Wired L2 100 eth0.

Even though I am not new to Suse, I am still very inexperienced, especially when it comes to wireless. I am running Suse Linux 11.3 and I am having problems connecting to my wireless. My network controller is a RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01). I am recieving a signal from my wireless router, however when I try to connect to my ESSID via KnetworkManager It asks for a WEP key. After entering the key, Knetnetwork manager will try to connect for a minute or so and then it will ask for my WEP key again. It keeps repeating this cycle without ceasing. How to configure the WEP so that Knetwork manager will connect or a way around WEP.

I can't get my wlan running, although it already worked on my notebook (Dell Inspiron 1545) with opensuse 11.1. Then I installed debian and, I don't know how, it changed my kernel in grub from .pae to .debug (renameing in grub didn't help)
According to the messages scanning fails
My wlan-controller is:
Router is avm Fritz!Box and is working fine with other notebooks and the lan of the Dell
I loaded down and installed the driver from Bradcom (hybrid-portsrc-x86_32-v5.10.91.9.3.tar.gz)
dmesg came up with a failure: not ipv6 server found - so I deactivated it

I have wired ethernet to my laptop. I want to be able to share my network connection with my iphone.
I have set up masquerading:
I have configured my wlan0 to a static IP - 192.168.1.100/24 call iwconfig to configure wlan0
I see the network pop up on my phone, I configure my own statis IP there, 192.168.1.100 as gateway
Success - I can connect to google for about 30 sec.
If I check iwconfig again, there is no longer a essid specified but a "CELL" value instead - and this is changing every 10 sec or so.
With the above I'm quite happy that I've configured everything OK except for iwconfig - why is it dropping my config?
I've a broadcom wifi nic and I'm using ndiswrapper.

In Ubuntu 9.10 (fresh install, not an upgrade from 9.04) on an ASUS EeePC 900, I was using wireless networking at home, which worked well. I took the netbook to work a few times and did not using it at home all that period of time. I connected it as a wired network (DHCP) at work, and it "just worked" fine (no configuration was needed). Now I tried to use it at home and wireless no longer works for all users. In System > Preferences > Network connections I can access the wireless configuration and it is still there, still with all the correct settings as worked before. However, in the network manager I access from the upper panel via the antenna icon, it now only lists a Wired network. The wireless network isn't in the list at all. No upgrades were done. I do those from home and tried to do one this morning but since wireless did not work I could not accomplish it.
I could hook it to a wired network, so if fixing this needs to upgrade something, that's doable (but I'd think it should not be needed since wireless did work before). I was going to try things like delete all networks and start again, but since that might lose information about a possible bug, I'm holding off.

And still, "no wireless networks found" in Wicd.

For the past week or so, I've had my wireless connection disconnect and reconnect at seemingly random intervals. It can be anywhere from every minute to every hour, whether I'm using the network or not. I don't recall installing anything that could affect this. I'm fairly certain this isn't a hardware issue, since I haven't had any problems when using my Windows partition. I'm using a D-Link USB adapter (DWA-171).
Code: Select alljp@pyrog:~$ more /etc/*-release
PRETTY_NAME="Debian GNU/Linux 7 (wheezy)"
NAME="Debian GNU/Linux"

My wireless network is down. I got thinkpad x120e, chipset: Realtek RTL8188CE, driver: rtl819ce.
Here is what I did so far:
upgraded to 2.6.38-bpo.2-686
installed firmware-linux-nonfree
Added the firmware file from the repo since it's not yet packaged in firmware-realtek and reloaded the module.
'iwlist sc' shows: 'wlan0 Interface doesn't support scanning : Network is down'
'dmesg |tail -20' shows:
rtl8192ce:rtl92c_download_fw():<0-0> Failed to request firmware!
firmware 0000:04:00.0: firmware_loading_store: vmap() failed
I also tried the following commands:
ifdown wlan0 ; ifup wlan0
ifconfig wlan0 up
Relevant bug: [URL]
Step by step, in case someone is interested:
add to sources.list: deb [URl] squeeze-backports main
aptitude update
sudo aptitude -t squeeze-backports install linux-image-2.6.38-bpo.2-686
install this package: [URL]
get the first file: [URL]
add to driver:
mkdir -p /lib/firmware/rtlwifi
mv rtlwifi_rtl8192cfw.bin /lib/firmware/rtlwifi
modprobe -r rtl18192ce; modprobe rtl18192ce; dmesg | tail -20

I've been enjoying wireless for a long time on Squeeze (iwl3945) with KDE, but the recent network manager update stopped that. I've tried a few things, like going back to /etc/network/interfaces and ifup wlan0 that I use with Lenny, but still not working.

I've been following this guide for squeeze: [URL] After getting the wireless-tools and firmware-ralink packages installed with no internet, I managed to installthe driver using modprobe rt2870sta (the 4th step). With the module loaded and the device plugged in (a RangePlusWireless Network USB Adapter with the WUSB100v2 chipset), iwconfig returned something like

and then ifconfig wlan0 up returned ERROR while getting interface flags: no available device

I am doing network config of my laptop. I'm new to Fedora, so I'm not sure how it goes ...
I have an Ethernet device (eth0) and a wireless device, wlan0
Status in system->administration->network:
Tab devices:
eth0 : active
wlan0: inactive
Tab Hardware:
eth0: system
wlan0: configured (description: b43)
Double clicking on the wlan0 line gets you to Network Adapters Configuration, where adapter b43 grayed out) is associated with device wlan0. So far, so good (I did all the fwcutter stuff, so I assume this is the result). When I installed the system (from installcd, then update, then install broadcom-wl, ...) I configured it to be started up with network manager, automatically on startup. I managed to get it working exactly once in that session.
Problem is, it doesn't start up and the wireless is not even visible when you click the network manager icon. For that matter, eth0 does not start automatically either, but at least there is a button to start it in network manager. Coming back to the tab devices, clicking on wlan0 allows you to click on the activate button ... but there it says: Cannot activate network device wlan0! b43 device wlan0 does not seem to be present.

I'm trying to setup a wireless AP with my old asus eeepc, so it can act as a repeater to connect my android device on the other end of the apartment. I've already created the Wireless Access Point using hostapd. It took very little configuring, just changed from mode 'a' to 'g' and changed the channel from 60 to 1 and It was all set. Next I setup a dhcp server. Also simple enough using yast.
Up to this point, I was able to connect my android device to the newly created wireless network. However It doesn't have internet access. I guess I have to configure iptables for this, but I find it incredibly confusing! Here are a few specs to help with any examples: The laptop is connected to the internet through eth0 with IP 192.168.2.120 Hostapd is using wlan0, and I'm pretty sure it created mon.wlan0 So, to sum up, when I connect my android device to the network I can, for instance, see what ever pages apache is currently serving on the laptop, but can't access the internet.

I am currently using Debian Testing, managing my wireless connection with NetworkManager and the Gnome nm-applet. Both have just been updated: network-manager from 0.8.1-6+squeeze1 to 0.8.2-6 and network-manager-gnome from 0.8.1-2 to 0.8.2-4.On installation of the new packages, I have no problems. However, on a reboot, I can no-longer connect to any wireless connection. I am not prompted on start-up for the password to unlock the Gnome keyring and when I left-click on the nm-applet icon and then click on a network to connect to it, nothing happens.I do not think this is a driver or NetworkManager daemon problem. If I run "nmcli dev wifi" or left-click on the applet icon, NetworkManager seems to scan for wireless networks properly and returns a list including the one I wish to connect to.

I upgraded from lenny to squeeze on a notebook and I can no longer connect to the wireless network. The computer is an LG notebook and the network card is ralink rt2860. I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked
$ lspci|grep Network
08:00.0 Network controller: RaLink RT2860
Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.

This may fall under the "ain't broke don't fix it" category but it's driving me nuts. I've got the Broadcom 4322 wireless adapter in my laptop and it works fine with broadcom-wl driver and kmod. However there is no ifcfg-eth1 file and the card does not show up in system-config-network.

I'd like to have a set up where my Ethernet card has a static IP set up but my WiFi card doesn't.Currently I have a profile for this set up in Network Manager, however on boot up and every time I replug the cable Network Manager chooses the default "auto eth1" profile. I manually have tochoose my own profile for the Ethernet card every time. How can I make it default??I know the workaround would be to use ifup but then I lose the ability to quickly change access points for my WiFi card so that's not a solution for me

New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.
Firewall
Disabling the firewall makes no difference.
Not using a network manager (can't see how to assign fixed address if I do - all greyed out).
ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'
(not sure why the warning - eth0 is assigned to external in the firewall setup).
