CentOS 5 Networking :: Wireless Goes In And Out Often?
Apr 18, 2011
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:
I have recently installed CentOS 5.3 in my system. I needed some help with the wireless configuration. Actually i have configured it and it shows the wireless name but it doesnt connect to it. in solving the issue.In the /var/log/messages , the following error appears :
getting a Wireless N pci card working with Centos 5.2-5.5? I am looking for a long term suitable replacement card that is not nearing its end of life cycle.
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'm trying to follow the instructions here to get my dell wireless NIC working in CentOS. I've got to step 3 but when I run the make command.But it does exist, as a link pointing to ../../../usr/src/kernels/2.6.18-194.el5-i686.
I recently downloaded and installed CentOS 5.3 DVD media.The media check passed. I proceed to install the operating system sucessfully. After installation, all my hardware is recognized, when compared to CentOS 5.2. Anyway, when I attempt to connect to my wireless network that uses either WEP/WPA/WPA2-- I get an error message that I cannot recall (it basically only came up when I entered the key) However, I can connect to my wireless network when it is unencrypted and no open/shared key is needed.I would like to be able to connect to my wireless network when
FYI: I am using a RealTek RTL8185 Wireless Driver.Also, I use CentOS as a workstation.
I am trying to use my air card (Sprint U760), which works under Windows, on CentOS 5. I have a manual from Sprint that has instructions but I am having trouble with installing required PPP packages. The Sprint instructions say to go to Add/Remove Software and download packages KPPP and KPPPLogView. However, these packages do not appear in the list of available packages. I do have a working hard wired connection to the internet while I am get the air card working.
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've been using Linux for about 2 years now, mostly Ubuntu & derivatives, but I've also tried Fedora, Mandriva, and others. I wanted to give CentOS a try because I'm very interested in going for a Linux+ or similar certification, and so I'm looking to start learning how to configure & maintain Linux servers and so on. I have a friend who's a Linux sysadmin, and he recommended CentOS as a good learning tool.
Anyway, I've only got a wireless connection in my office at home (the actual cable modem is downstairs) so I intentionally chose a wireless adapter that would work with Linux -- it has a Realtek RLT8187 chip, for which there is support built into the kernel, or so I've read. It has worked out of the box in just about every distro I've tried, and indeed it worked OOTB when I tried out the CentOS 5.5 live CD.
However, when I actually installed the CentOS to my hard drive it no longer worked -- I have only a greyed out option for a wired connection (presumably since my motherboard has an ethernet adapter, but there is no connection). Why the wireless would work in the live session but not after install? Is there a firmware file or something I need to track down? I did look on this page, but it doesn't mention anything about RTL8187.
I have a couple of dell precision boxes running centos 5.4, that are occasionally sent to trade shows. I would like to set them up to connect to wireless networks. Question, what is generally considered the best usb wireless nic to purchase for this distro/release? Also, any opinions on the best wireless aircard and carrier to use, ie; sprint at&t, etc?
I have a desktop and a laptop. I have Netgear WGR614v9 Wireless Router connected to my desktop. Since my Laptop is pretty old I also bought a Netger Wireless Adapter for the sme model. Now when I connect the Wireless Adapter I am unable to connect to Wi-fi. I am new to Linux, after googling I ran "lsusb" command and it showed Netgear Wireless adapter and its version. Also in GUI when I open File Browser it also shows the Adapter detected but I am unable to connet the same to my router. Also the blue light on the adapter is not glowing.
I have a SSH box which is command line only and no X, this will be used remote and i'm trying to get the wireless network configured to start at boot. I'm using wpa_supplicant as the access point is secure with WPA2 At present if I send the following commands the machine will connect to the wifi and be reachable via ssh
This does not start at boot but requires manual input of the above commands. I've just come to a complete blank on geting this to start at boot time. Also I would like to set a fixed IP for this box.
I have been trying searching and reading for a few days now and I have had no luck getting a Encore ENLWI-G2 wireless pci adapter to install. I downloaded their Linux driver [URL]...and I keep getting errors on the makedrv (attached). I get a couple "make: *** /lib/modules/2.6.18-92.el5/build: No such file or directory. Stop. " errors but the modules appear to be there.
I have not touched Linux in 5 or 6 years, so pretty rusty. I have a call in at Encore support and will post their solution if they get to me first.
working to sort out the damn wireless for too long. Mine in cent05 5.2 . network manager is on and I can see the icon on tray. It list all the wireless connections too, but just won't connect. WPA encry is disabled. further details below:
I have a Sprint U760 air card that apparently works under Linux. Sprint has a guide: "Wireless Mobile Broadband Setup Guide for Linux OS" that I am using to setup the air card. When I go through the procedure in the manual for "Setting Up PPP Using KPPP" the last task is to query the modem to see if Linux recognizes it. When I do the query I get a response "unable to open modem". I have tried going back through the PPP setup but still get the same response.
installing my wireless card Atheros AR9285.I have tried to get it working with both compat wireless - Ath9k driver but I dont know exactly how to do.I have also tried to get it to work with ndiswrapper, but it is really tricky because nothing is available in centos like precompiled ndiswrapper.I used to work with Arch Linux so everything in Centos is totally new to me and I don�t understand a thing:I need to get it to work as soon as possible.What I have read the should go to just "activate" the ath9k driver with my card and it would work,
I've search for info on configuring ndiswrapper for the BCM4318 Wireless card. All I've been able to find is information on Ubuntu and Debian, which don't seem to use the same methods for configuration. Has anyone configured ndiswrapper for this or any wireless card on CentOS 5? I've installed 5.4.
I recently purchased the Linksys WMP45G wireless card for my desktop (as my router is too far for ethernet cable). I can't get it to work. The NetworkManager icon doesn't appear in the upper-right corner, despite being up-and-running. Here is some output:
[root@cwatson ~]$ uname -a Linux cwatson.homeunix.net 2.6.18-194.11.1.el5.centos.plus #1 SMP Wed Aug 11 08:19:38 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux [root@cwatson ~]$ yum list installed "Network*"
I have CentOS 5.5 and I can't install the driver for the Atheros AR5006X Wireless.The current state of my CentOS is:
*) If I run lspci, I get 03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01) (wrong model) *) If I go to System->Administration->Network, I see the wlan0 device with xlan0 name, but if I tried to active I get: (and the same when the system is rebooting)

I've only used Linux for about a year or two now and have worked through suspend esume and WPA wireless issues with CentOS and my T61p. However, I'm stumped on this one. why my T61p freezes randomly (happened once while writing this topic) with the caps lock light blinking. I'm wondering if it has something to do with my nVidia driversettings andor using my wireless card and/or switching between home wwireless and work wwired connection.
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 just recently installed CentOS 5.3 and to make a long story short I found the entry for my wireless card under the network settings but when attempting to activate the card the system locks up. I have to reboot at that point as nothing responds (keyboard, mouse, etc..).
Running the command /sbin/lspci -v reveals the following about the wireless card:
I'm trying to find a driver for my wireless card (Atheros AR928X) and I think it's ath9k what I need. As far as I know there isn't a linux driver for it, so I installed ndiswrapper to use a windows driver instead. The problem is that when I type modprobe ndiswrapper I get "bash: modprobe: command not found" (even as root). I know I'm missing something about modprobe, but I can't find any help on google. Anyway, I installed ndisgtk next, because I thought it would be easier, but when I go to System> Administration> Windows Wireless Drivers I get a message "Unknown error".Do you have any ideas on how I'll make ndiswrapper work?
