I installed CentOS 5.4 on my desktop yesterday after facing crashes from Ubuntu 9.04 Everything worked fine and few didn't which I could resolve, but this problem is absolutely strange to me. I've USB wireless adaptor Belkin F5D7050 v4000 which uses a zydas zd1211 chipset. The problem is that I've not been able to connect to internet or even in the local network. (I've this another Laptop (Windows Vista) which can connect to internet and thus I can post and download stuff.)
I read the CentOS wiki [URL] to setup the wireless network and it asked me to download a firmware for it.. I downloaded and installed the firmware from the specified location but to no respite and I can't connect to network. now the strange thing is the result of iwconfig which was here even before installing the firmware. iwconfig shows

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 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 have installed CentOS 5.3, and updated with yum update. I have kernel 2.6.18-128.1.10.el5xen.
I can't get my wirelss network to work, I have AR928X wireles network adapter.
Do I need to install a newer kernel and install ath9k or can I just downlad a driver without updating the kernel?
I'm new to CetOS and Linux so I hope someone kan give me a step by step guide to what I can do!

I configure the wireless connection. It works. I restart, and and doesn't automatically even though it asked my if I wanted to use the profile next boot and I said yes.. How do I get it to save? I tried several times.Maybe there's a terminal command? The computer is for a COMPLETE newb who only wants it to browse web, but they're not going to know how to connect every time even if I explain.

So, after installing Lucid wireless doesn't work for me. When I click on the network icon on the status bar, it shows "wireless is disabled".
With that message, I press the wifi button on my HP laptop and it turns off my blue-tooth, without changing the status of my wifi.
I found this rfkill command in another thread:
Before doing anything, after bootup:
Code:
$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

I'm releaving a HP Probook 4710S from it's native Vista) First of all let me say I'm happy because CentOs 5.6 handles it's Ati Radeon graphic flawlessly, unlike other Distro's I tried on this type of machine. So thumbs up for CentOs! But now I've come to a stop on the wireless card.

I've been having some issues lately with my wireless connection going in and out. I'm attaching some of /var/log/messages that I think would be relevant. It kind of repeats after the first couple hundred lines.The first issue I see is on line 79 of the file:
Apr 18 11:53:44 cwatson NetworkManager: <info> (wlan0): device state change: 8 -> 3
Apr 18 11:53:44 cwatson NetworkManager: <info> (wlan0): deactivating device (reason: 11).

wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.

I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.

I am having a little trouble connecting to my wireless network. Running Fedora 10 32 bit.I'm trying to connect to a hidden wireless network. I updated the firmware for my driver but apparantly the driver is still not working. Broadcom has a driver from their website for Linux 32 bit systems. Should I attempt to install it? I read a post where the driver is built into the system kernel. If so I would need to blacklist the one of the drivers. Correct?
[justin@justin ~]$ iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
wmaster0 Interface doesn't support scanning.

I have just installed CentOS 5, and am new to Linux. So I don't know much about the terminal commands or much of anything else for that matter.
I'm able to get online when I plug an ethernet cable directly to the computer, but cannot get it to recognize my wireless(which I do have the drivers for, and did work previously on Windows).
The card is a Linksys WMP54GS.
I downloaded ndiswrapper-1.54 but still cannot figure out how to get this to run. As I said, I'm new, so I'm not sure what information other than that to provide, and how to access it, so you may have to guide me through that.

i didnt find a solution to a display problem im having. my server mobo is an asus k8n-dre with built in video. after the install(using built in video) the screen dosnt display fully as in black sections on the left and top of the screen. from the searching i did i found something about an "xrandr" command that would let me change the video settings but it didnt do anything with the black areas when i tried it. i also have a nvidia geforce 9500gt video card so i changed the jumper to boot from it and tried again. the black sections are still there but the centos display covers much more of the screen now. theres still about a third of an inch gap on the left hand side and about 1/4 of an inch on the top. ive also tried updating the software to see if it may be a driver issue but no luck. anyone know how or if it can fit to full sceen? the screen displays up to 1440x900 if im not mistaken but with the built in video it gave me lots of display options including the 1440x900. after changing to the nvidia card it only shows 800x600 and 640x480.

I installed Debian Squeeze on a new Acer Timeline.
lscpci gave me this
I used the Debian Wiki [url] to get the wireless working, but it's not happening.
iwconfig gives this:
The Network Manager shows (under Wired Networks) ifupdown(eth0) - I've never seen the "ifupdown" here. Wireless shows as disabled.
When I boot I see a few of these:
But I get No DHCPOFFERS received. So, Wireless is disabled.
