CentOS 5 Networking :: ZyDAS Virtual Media For 802.11bg - Wireless USB Device Not Working
Jan 12, 2010
I just installed Centos 5.4 on the 2nd partion of my hard drive. I have an ethernet card in my machine (a 3Com Corporation 3c905 100BaseTX [Boomerang] card), but I need to be able to use my wireless USB device I bought from my local phone company (Qwest)...because I will not always have the luxury of plugging in to a hard-wired connection. The USB wireless device works fine in Windows, but I need to be able to use it on my newly installed Centos 5.4 partition.
Here's some info:

I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.

i have some basic knowledge about device drivers.can any one tell how to write drivers for virtual modem, Actually my project is to implement communication between the two PCs by using two virtual modems. so for that i need to write the code for the virtual modem which it should understand all the AT commands exactly as physical modem and it should send/receive call and SMS.

I have spent considerable hours searching forums and googling. I have yet to find out what "lm-sensors acpitz-virtual-0 Adapter: Virtual device temp1:" is actually looking at. I have an Abit IP35 motherboard with Ubuntu 9.04 installed.
Here is the output from sensors:
Virtual Device Temp 1 keeps going up to 121 degrees and the computer shuts down. None of the others overheat. Also, my bios does not show my voltages to be set like it lists above. The bios in the motherboard is the latest from Abit.

The computer networking works fine with a normal static setup, but adding a USB wireless device is not successful. It is my own network so the wpa-ssid and wpa-psk are known to work with Lenny and a previous wireless device.The device is recognized (lsusb) and the driver is confirmed to be in the kernel (lsmod). Here is the iwconfig output:
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
After typing: ifconfig wlan0 192.168.1.144 up I can ping that address, but it is not working. I have just done a fresh install of Sid so that I could get the 2.6.35 kernel which contains the ath9k_htc driver for the USB wireless device that I am using. The firmware is ar9271.fw but my source of that is questionable because it does not seem readily available. I am temporarily using a PCMCIA wired connection which is what I am using to connect to the computer via telnet. (This is just for convenience so as to avoid getting up all the time.) Here is the ifconfig output:
eth0 Link encap:Ethernet HWaddr 00:40:05:07:d9:11
inet addr:192.168.1.122 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::240:5ff:fe07:d911/64 Scope:Link
[code]...
That file works with the previous USB wireless device under Lenny. Am I doing something wrong or is the driver and firmware just not up to snuff yet?

My HP laptop has a wireless network device, Atheros AR5007 802.11 b/g Wifi adaptor. I was previously running Vista on this machine, and today loaded CentOS 5.5. In system-config-network, this device shows up properly in Hardware and in Devices. Hardware device shows the right mac address. In General, I set Activate device when computer starts, Automatically obtain IP address setting with dhcp, and Automatically obtain DNS information from provider. I've left the DNS and Hosts page blank.When I try to Activate the device, I get
"Error for wireless request "Set Mode" (8B06):
SET failed on device wlan0; Invalid argument
Determining IP information for wlan... failed."
I have tried nfs restart, to no avail. (When I do this restart, I get the usual OK on seven of the messages but Shutting Down NFS services " shows FAILED.) I know the wireless router is working because I am connecting to it from another machine.

I am new to Linux and after a lot of research I settled on CentOS to be my OS for Linux. But I am having trouble with sound right now as I can not play audio. The command system-config-soundcard opened a gui for audio configuration saying following device is detected - Intel Corp. 82801(ICH9 Family) HD Audio Controller.
Ouput for some commands are given below::
[root@localhost ~]# lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) .....
[root@localhost ~]# uname -r
2.6.18-164.el5
[root@localhost ~]# cat /etc/redhat-release
CentOS release 5.4 (Final)
Clicking on the volume icon gives me message that either Gstreamer plugins are not installed or sound card is not configured.
While Trying to install gstreamer using YUM, I got following message:
[root@localhost ~]# yum install gstreamer
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile .....
Setting up Install Process
Package gstreamer-0.10.20-3.el5.x86_64 already installed and latest version
Package gstreamer-0.10.20-3.el5.i386 already installed and latest version
Nothing to do
[root@localhost ~]#
So I guess gstreamer are installed but how to configure the sound card or is there any other problem.

I am doing some experiments comparing the performance of wireless under 3 different cases:
(i) without media sensing (carrier sensing).
(ii) with media sensing but no RTS/CTS
(iii) with media sensing and RTS/CTS
I know RTS/CTS can be controlled by iwconfig interface rts {N|auto|fixed|off}
However, what about media sensing? Can it be disabled? If yes, how?

I want to add more than one Virtual IP to my CentOS machine. I was able to add one ver easily by creating a file ifcfg-eth0:1 and editing the IPADDR field. But I cannot create more by creating a ifcfg:eth0:2, for example.

I have a Dell Inspiron E4300 provided to me by my employer. I have installed CentOS 5 without much of a problem. The only issue is the wifi isn't working (doh!). I've had much experience with this kind of thing in the past (FreeBSD/ndiswrapper) with successes.
Here are some details:
[Code]...
The device does not appear in dmesg :(I have installed ndiswrapper (dkms-ndiswrapper and ndisgtk from RPMForge) and provided it with the correct Windows XP driver. It has installed the driver and ndisgtk tells me that the hardware is present.

I'm trying to get WiFi up and running on an older desktop PC. lspci gives me the following information about the WiFi card: 00:0d.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01) Is there an RPM package for the driver that I need? If no, what should I do to install the driver manually? The PC in question doesn't have any other form of direct internet access. It does have an Ethernet port, but the WiFi router is too far away to hook it up to the access point directly.

I'm running Linux 11.04 and my wireless network was working just fine until today. I cannot connect to WiFi - it acts as if the device wasn't there. The hardware switch led isn't working. No matter how much clicking on it, it won't work.
iwconfig:

Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.

I have freshly installed ubuntu 9.10 and moreover i am completely a newbie to Linux. The problem now i am facing is, i am not able to configure my wireless router. I tried finding drivers for it in System->administration->hardware drivers. But it showed me none. Then i checked out one of the threads in this forum and came across the 'lspci -nn' cmd. This gave me the info abt my wireless network controller and it was : 'Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)'.

I've tried to install Linux systems have been failures. Trying to make this work, trying to get on the right wagon, and it's frustrating as all get-out.
Installed netbook remix onto a HP Mini 1000 (1116NR?) and everything seems to be working alright, except no wireless networking. I tried a couple of things and now it shows "device not ready" instead of "disabled", so I figure I'm getting somewhere.
The device is:
Broadcom Corporation BCM4312 802.11b/g (rev 01)
I want in. This is my 3rd try over the years of running Linux and I always hit snags like this that I can't fix because I've never gotten to play with it enough to learn what I'm doing and generally don't have a 2nd computer like I do right now.

It's been ages since I've been on here I've been messing around with BackTrack. I've come back to Ubuntu but seem to be having some problems getting my wireless network thingy working. Here are the specs of my system. Any advice on fixing this would be very very apprciated.
02:06.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01)
02:08.0 Ethernet controller: Intel Corporation 82562ET/EZ/GT/GZ - PRO/100 VE (LOM) Ethernet Controller Mobile (rev 01)
10:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
On another note I'm trying to run debain I've got no startx on there or anything like that it's feeling very basic atm. I want to keep startx outta there but I can't connect to the Internet and run apt-get install to grab handy things.
I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?

Not sure if this is a networking issue or not but I have a Buffalo drive NAS device that I have my mp3 on. I can see it from my Ubuntu laptop, I can see it from my windows laptop. However when I go to my centos system and the networking option under the places menu nothing comes up. I do see a workgroup and a network option. I tried both but just opens a blank folder. How can I get this drive to mount to my centos system?

HeI just started up my netbook (Medion Akoya E1315), and for no apparant reason, the little icon in the top-right corner (the Network Manager) says "Device not ready" in grey. So, after looking on a million forums and websites, I decided to go for a complete re-install of Ubuntu (9.10 netbook remix). I took the same driver that always worked before (RTL8192), and installed it with succes: I had wireless again!But, of course, as these things go, after a restart of my laptop, the same problem occured. So the obvious question: What is this problem?
Here's what I did: I downloaded the tar.gz from Realtek. I downloaded RTL8192se, untarred it and gave the "insmod" command. And that worked before.I also downloaded WICD as an alternative to Network Manager, but that just gave no for an answer.

I want to switch my laptop from XP to Ubuntu, but right now, i cant risk installing it. i dont want to have it partitioned so i can dual boot, so for now i only run the try-it-out mode.Before i consider installing though, i want to see if i can get everything to work ahead of time, that way im not regreting instalation. I have a Compaq Presario V2000 laptop, with 55GB hard drive and 516MB ram. So far, the trial mode is working great, but the wireless will not work. Ive tried to install the driver, but i am unable to do so. I have looked this up, and i have tried many things, and so far, none have worked.I was wondering if it was just part of the trial thing or not, but it is a Broadcom Wireless BCM4318 driver

I've run into a problem gathering usage for my xen virtual systems. With my old model I used to gather all network usage via my cisco devices using the the counters for each port. Each system had it's own port on the switch, and I tracked network usage accordingly. Now that I'm using xen for virtual systems, and multiple vm's share the same switch port, i'm not exactly sure what my best option is for tracking usage.
I thought I may be able to setup vlans on the switch, and bind each vm to a different vlan using vconfig... but it seems like there has to be a better solution than that.

I have just installed openSuse 11.4 KDE 64-bit on a Dell M1330. When I click on my networking panel, it says WLAN interface is unavailable. I've followed the steps in the stickied post and found the WLAN hardware info, a screenshot of which is below:Uploaded with ImageShack.usNext it says to do this - you need to look at the logs, in particular the info in /var/log/boot.msg. To see this, you need YaST => Miscellaneous => System Logs and select boot.msg.In YaST there is no such option for system logs under miscellaneous, so I can't do that. The results of the sudo /usr/sbin/iwlist scan command produce the following:

eth0 Interface doesn't support scanning.
