Also having this problem on Ubuntu 10.04.If I do "iwlist scan" I can pick up networks on wlan0:

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
...

[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've looked everywhere and tried everything. All I want to do is set up a static ip with my wireless network interface wlan0.

I have managed to configure a wireles PCI card on CentOS 5.3 and it seems to work fine. It is a off brand (Hercules) with a Ralink RT61 chipset. I installed the most current driver (RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) from the rt2x00 Open Source Project. I now have a question that might be very simple for one or more of you to answer. When I issue the command "shutdown -h now", the machine starts to come down and brings down eth0 cleanly, but when it attempts to bring down wlan0, the machine hangs and never brings down the interface OR powers off the box. The only way to complete the power off is to "hard" power off the machine.

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 got a problem while accessing the /etc/sysconfig/network-scripts/ifcfg-wlan0 file, CLI's throwing: "Stale File Handle" - there's no access to this file. Problem is the same regardless wlan0 interface is up or down.

I was using ndsiwrapper with XP driver, but always prefer to Linux drivers if they are available. So, I emailed Realtek web support and they sent me latest drivers for Ubuntu 10.04. I followed their instructions and it works great! With, the exception of, I have to run ./wlan0up each time after I login to start the wireless.
I seem to remember having to modify a file some place, which was very easy to do, but for the life of me I cannot seem to remember what it was or what to put into it? and also, how do you tell if your wireless card is making use of the "n" speed, if the network your are on has it available?
I have a wired connection going to my router, which is encrypted with WPA2-PSK. That works fine. I hooked up a WUSB54G v4 (Linksys USB Wireless Adapter), and used ndiswrapper to install the drivers from Vista to make it compatible with WPA2. Also configured the /etc/network/interfaces with the wpasupplicant lingo to make it all work. So if I do that, my eth0 will not work anymore. Also on a side note my network manager stops with displaying in the top panel. Not a problem I can run /etc/init.d/networking (re)start and dhclient eth0 (wlan0) and all the other commands that are necessary to make it work.
Back to the problem, so I hook up wlan0 with the settings and eth0 stops working. I want to use the wlan0 solely for the purpose of my media server. The eth0 is there for my internet and that is it .
How can I keep 'em separated?
I recently upgraded to ubuntu 10.04 after not using linux on my PC for a few months. After the upgrade, everything worked fine except my wireless card no longer works. It seems to have disappeared from my available interfaces. Here's the output from lspci:

I've been through posts about similar problems that did fixes using things like blacklist and modprobe, but none of these worked. I've searched the RaLink webpages for more up to date linux drivers but found nothing that worked - I downloaded the RT3090_LinuxSTA_V2.3.1.6 driver and followed the instructions to try and build it, but this didn't work.
I just installed Ubuntu 10.10 on a Sony VAIO VGN-NR110E.Literally, every other time I boot the wlan0 interface is missing. I saw that there used to be some problems with network manager in the past. My NM is running fine. When this happensCode:sudo ifconfig wlan0 upreturns:wlan0: ERROR while getting interface flags: No such deviceIf I reboot the wlan0 comes back up
View 2 Replies View RelatedI'm running Ubuntu Server 10.10 on a 64 bit laptop (also have GNOME installed just for convenience), and have a website up using apache2. I am wondering if it is possible to configure both eth0 and wlan0 to the same local static IP address? I would like to walk around my house and do stuff when I want and still have the website accessible, but also be able to jack my laptop back into the router when I am away, just for peace of mind.
Is this possible? If it is, do I need to do some configuring in apache2 to tell it to use another device? Is this even a smart way to get what I want done?
I have an Ubuntu server installed at home, on an older machine. Unfortunately I am to far from my router to run cat5 and solve this issue. But I want to be able to have the wireless come up if the server restarts as then i could log in remotely.

I just switched from Fedora 13 to openSUSE 11.3 on my laptop and so far love it...well...not quite. I'm having some major network issues. As in...no networks.
I installed everything and booted up for the first time. Everything worked great, I had wireless through wlan0 and could connect directly to my home router via eth0 with no problems. Installed a few applications and ran into some problems with hibernating/suspend modes. I rebooted and like magic, NetworkManager said networking was diabled. My WiFi light was off. Network switch on the computer didn't do anything.
I thought alright, I'll connect my ethernet cord and can go from there....problem is that won't work either. I tried searching for drivers online on my desktop, found some and transferred them via USB with no luck. They won't install. I have no idea why, or whats going on but I really need my laptop for school on Monday so it would be AWESOME to have it working by then.
Here is what I have:
Intel 5150 WiFi card
Dell Studio XPS M1640 laptop
OpenSUSE 11.3
Recently, I've set up Ubuntu Server 9.10 x86_64 (no GUI). I have two NIC cards in this machine. One is a wireless card that I would like to set a static IP address to. The other is an integrated NIC. Everything works just fine when I have everything set up under DHCP. I can ping both NIC cards with no issues. But as soon as I change over to a static setting, things work unexpectedly...
Things to keep in mind:
-All machines are running under the same subnet
-All machines are connected to a wireless router (freshly flashed with the latest firmware)
-This is a fresh install of Ubuntu Server 9.10 x86_64
--Static IP address on the WIRED (eth0) NIC works great. No issues. Can ping from my wireless laptop, and can ping from the machine to the outside world (ping google.com) as well as the gateway itself with excellent response times.
If I then turn on the WIRESLESS (wlan0) NIC after setting up a static address for it in /etc/network/interfaces, then turning the wlan0 on by issuing "sudo ifconfig wlan0 up", wlan0 shows up, but does not have an IP address associated with it, even though I set it up as static. I also cannot ping wlan0 from my laptop. I assumed that was because I needed to restart the networking service. So after issuing "sudo /etc/init.d/networking restart", I am able to ping wlan0 from my laptop with no issues.
Here is where things get strange. Lets say that I physically pull the plug on eth0. After dong this, wlan0 stops responding to the ping request that was initiated by my laptop at the same exact time. If I plug the cable back in, both eth0 and wlan0 begin to respond once again. But soon after I try to SSH to wlan0, wlan0 decides that it no longer wants to respond to the ping. I should note that it does ask me for a username and a password, but after I entered my password, the ping stops responding. Why should the wlan0 be affected in any way if something happens to eth0?
This all started when I set the server up with only a static configuration on wlan0. It appeared to be working well. I was able to ping the machine from my laptop as well as SSH into the machine. I went to bed and the next morning, I was no longer able to ping the machine. I let the ping run for a small amount of time with a few responses here and there. Then after a little more time of letting ping run, it tends to respond. Almost like I bothered it enough to decide that it was appropriate to start working again.
Ideally, I would like to have ONLY a wireless connection. But if I need to have eth0 up, it would be great to have option work as well. Bottom line is that my wireless is flukey. And I would like to find out why.
I'm running Linux Mint 10 . I have a wireless PCMCIA card (Linksys WPC 11 ver.3) that I've put into master mode, and I'm trying to set up my laptop as a wireless hotspot. I am very confident that I want to do this and have no interest in using a wireless router....I say that because that topic inevitably comes up with posts like this. The problem I'm having is I don't understand how to get wlan0 and eth0 to "talk" to each other...That is, I don't know how to set it up so that traffic from wlan0 goes through eth0, so that devices that connect to my hotspot can access the internet.I've seen a few guides about this, but they were either much broader in scope (i.e. much more complex), or for other distributions, etc, and it's too much for me to follow as a linux .
View 6 Replies View RelatedI have a strange issue that I cannot put my finger on. Recently,I installed a new Ubuntu 10.04 server. No extra software yet, apart from openssh-server. The wired connection (eth1) works fine. I then added a wireless card with chipset p54pci, which appears to work with the wext driver. Configured /etc/wpa_supplicant, and /etc/network/interfaces as well:
This is wpa_supplicant:
Code:
This is interfaces:
Code:
After a reboot the machine comes up with both NICs active.
If I do a ssh from another Ubuntu machine to this machine (to 192.168.2.100, so the wired address) it takes about 30 seconds before I get the login as: prompt.
If I change the interfaces file so that wlan0 is not started (I comment out the line auto wlan0, and reboot), connecting from another machine with ssh alsmost instantly gives me te login prompt.
I tried switching the order of both NICs in the interfaces file. Also tried changing the sshd config file so that it only listens on the wired ip address. Both did not help.
Does anyone have a clue why logging in with ssh from another machine is very much slower in response with wlan0 activated than without ?
p, li { white-space: pre-wrap; } Laptop connects to a (wired) ethernet port on a DLINK DIR-625 wireless router using dhcp. All works perfectly.
Using the same laptop connecting to the same wireless router, but using the wireless adapter and dhcp instead of wired ethernet, I can ping IP addresses on the LAN and also WAN IP's to/from anywhere on the net. I can perform reverse name resolutions (ip to host name), but not forward lookups (host names to ip addresses). I can use the DNS server obtained from dhcp or specify, by ip address, a DNS server to perform the lookups. This makes no difference.
Web pages (LAN server pages or from the internet) are not accessible by site address name or by ip address specifically.

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.
change my WLAN0 MAC address in my Kubuntu Natty 64 bit at every boot. I have done quite a bit of searching and found some procedures that appear to have worked back in 9.04 and before days but I have been unable to get anything to work for me in my 11.04 install. I have tried adding a script to if.pre-up.d and also tried adding a bootmisc.sh and either I did them wrong or they are not working. I want to make sure that every time I bring the wireless up in Kubuntu that I have the changed MAC address. I usually keep wireless disabled and turn it on just when I need it.
Background so you don't think I am doing something nefarious... I am going on a cruise soon. The cruise line sells wireless internet subscriptions for the duration of the cruise but they tie it to a MAC address. I am bringing my CDMA android phone that unless I use VOIP will be unable to call at all or at least with very high charges. But I also want to be able to browse the internet with my laptop. I figure it will be easier to spoof my phones MAC with the PC than the other way around. I just need to turn one device off if I am using the other. I need the MAC address to be semi permanent so I don't turn it on by mistake and have forgotten to change the MAC.
just wondering if I could get a hand with bridging my eth0 and wlan0 connection. I'm using Ubuntu 11.04 if that helps at all.
View 1 Replies View RelatedI would like to pose is very specific to a system I'm assembling. I have ask for assistance from other forums and people, however the answers receive were too vague to implement.
As for my background, I am a network user able to write TCP Linux client/server applications quite easily. At a Linux system level I do not understand the necessary combination of applications and services to affect the following;
Network components;
- WiFi access point/router with four ethernet ports
- Laptop (user computer) cabled directly into the access point via a physical cable
- Second computer running Ubuntu 10.04, with one WiFi (wlan0) and one ethernet (eth0) interface. Eth0 is configured as a DHCP server with the following;
IPaddress 192.168.252.1
broadcast 255.255.255.0
Eth0 is physically connected to an IP camera via a Cross-over cable. The camera is configured as a DHCP client. This connection works perfectly from the Linux box with a KVM attached.
Wlan0 is connected wirelessly to the access point and the Laptop can access the Linux box and vice versa.
My objective is to have the
- Laptop via the access point/router connect directly to the IP camera on the Linux box via the wireless link.
- I would prefer not to make any configuration or routing changes/entries on the access point/router.
The type of response I'm looking for;
- is this possible at a macro level
- what facilities/server are required on the Linux box (I would like all configuration applied to this computer only)
- what commands need to be executed and in what order. If possible a brief explanation of why the command is needed and where it fits in the grand scheme of the solution.
This is probably a gigantic request outside what the forum usual activity.
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..."
