CentOS 5 Networking :: Cannot Get Wireless To Work ?
Apr 5, 2009
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.
Wireless networking doesn't seem to work. When I try to create a new network interface with system-config-network, my wireless card doesn't show up. The following comes from dmesg:
I saw a post about this elsewhere and downloaded some firmware drives from [URL] and installed then. But, I'm really out of my league when it comes to this kind of stuff.
I am a linux newbie, I spent more than 3 days trying to set up the drivers for my Intersil Prism 2 Wi-Fi adapter on CentOS 5.5. While trying to Make the driver source I receive errors of missing libraries. Is the hostap driver included in the Centos Kernel? I tried with insmod hostap but it didn't work..? Is there a kernel patch with the hostap drivers? I will be glad if someone can give me ideas or directions for setting up the driver properly.
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 :
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
Recently I have installed Fedora 14 on my other laptop. It's a dual boot with Windows 7. Everything worked perfectly fine, networking included, until my friend didn't accidently turned off the wireless by pressing a wireless button on the laptop. Since then the wireless on Fedora doesn't work. It does on Windows thought. I've tried restarting the laptop few times, but the wireless still doesn't want to work again.
i installed ubuntu along side of xp, and i cannot get my wireless to work. the drivers that are installed in xp work great, and i can access the internet, but do not work in ubuntu.
I have a Belkin Enhanced Wireless USB Network Adapter Model # F6D4050 v2. The drivers are for windows but the windows wireless drivers app doesnt work. I see a tutorial for a linksys that appears to have the same chipset, but I am not sure if any of the steps need to be modified, also my kernel is a bit different. Here is my kernel:
I can't get my card Intel Wireless 5300 AGN to work. I'm running Slackware 13.1 and it's a full, fresh install.I get to show up with lspci -v:Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection...But it will not show up with 'ifconfig' which will only list the local loopback (yes we have have a eth problem as well but one thing at a time).
I am trying to set up an unused machine as a web server for my students.
I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.
1) The built in Realtek RTL8139 configured as eth0.
2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.
I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.
When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?
I'm in a hurry to get the wireless to work on my Toshiba A205. Link to system data: [URL]. Didn't have to use anything like ndiswrapper on ubuntu, so thinking its an easy todo here - just need a little prod or two in right direction. In the meantime I'll take a look at the data myself and see if I ain't smarter than I think.
I have a Centos 5.2 VM running under Windows 2008 Hyper-V. If I add two "legacy Nic's" and bridge them, everything appears to work fine. However, if I remove the legacy nics and replace them with two synthetic nics (linux integration components), the nics seems to function fine UNTIL I add them to a bridge.This VM will eventually be used as a DansGuardian/Squid transparent proxy for a local library. The logical layout is represented by the attached jpg image. I have also included the ifcfg- scripts for the adapters and bridge for both scenarios.It would also be useful if someone else has Hyper-V with the integration components and dual physical nics to see if they can reproduce my symptoms on their box.Legacy Adapters:
This will be a little long (having read Phil's 'how to ask questions' FAQ). I'm trying to get OpenVPN working between my CentOS server and some Windoze laptops running XP. There seems to be plenty of sample config files available, but to date, none of them have worked for me. Pulling out my trusty Wireshark, I've found some clues,
BACKGROUND: My local subnet (NAT'ed by my gateway router) is 192.168.52.x. My router has been configured with a conduit (port-forward) for port 1194 (the standard OpenVPN port), which points towards my CentOS server.The CentOS server is .52.112, and the supplicant is .52.110. I have tried the lient both inside and outside my local subnet, with no difference in events or outcomes.
I got myself a shiny M305 Logitech mouse for my laptop. It comes with a littlee USB wireless dongle. When I plug in the dongle, DMESG shows me that the system notices the dongle:
usb 5-1: USB disconnect, address 6 hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. usb 5-1: new low speed USB device using uhci_hcd and address 7 usb 5-1: configuration #1 chosen from 1 choice input: Logitech USB Receiver as /class/input/input15
I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.
I am trying to use CentOS 5.4 to set up a secure laptop, largely because of it's SELinux functionality. Unfortunately I couldn't get wireless to work properly using the default NetworkManager so I installed wicd. Initially it buggered up my whole installation but after relabelling files using SEL I can now use my system again. but.. I can't use it with SELinux enabled, as it denies the required accesses for wicd to work. I also get similar SELinux denials for wpa_supplicant. A couple of snippets from /var/log/audit/audit.log -
How to get my wireless to work. I'm currently running Ubuntu 9.10 on a Dell Inspiron 2200. The wireless adapter I'm currently using is a Linksys WPC54G ver. 3.
When I enter iwconfig lo, eth0 and wmaster0 have no wireless extensions. wlan0 says
I tried following the instructions here:[url]
But when I enter sudo ifdown eth0 it says internet eth0 not configured. then wlan0 it acts like it doesn't even exist.
I'm very new to Ubuntu and Linux in general. I installed Ubunutu NBR on a HP Mini 2140. After some wireless issues and a bad decision, I deleted the ssb.ko files. Now the wireless won't work at all. How can I repair the SSB modules or reinstall those files?
I've installed Ubuntu 9.1 on my Acer Aspire One ZG5 that was previously running Win XP with the wireless working fine. In ubuntu,though, i can't get the wireless to work at all and I don't really even know how to troubleshoot it. I've opened a terminal and used sudo to update various packages, but still nothing. It does appear as though the system recognizes the card since I can configure it, but I'm not keen on playing wi8th the BSSID and MAC address stuff because I just don't have any confidence that it will change my situation. Has anyone had any success with this setup (ubuntu 9.1 and acer one)? Is there a step-by-step wireless troubleshooting/ configuration process that's generic to ubuntu?
Let me start off by saying that I'm a complete Linux-noob. I just installed Ubuntu 9.10 and I'm really enjoying it. I was planning to install it for quite a while now but now that I have my own computer, I actually could make it happen.That being said, it's a whole difference with Windows though and sometimes it's hard to find my way in this new system. My main problem is that I can't seem to get my wireless connection working. From what I've read online this problem is not uncommon with Ubuntu 9.10?
I tried searching for my wireless card drivers in 'System > Administration > Hardware Drivers' but that didn't really work out. It did find a wireless card driver but when I try to activate it, it returns an error message. All the other drivers seem to be installed so I can't really see what the problem is. Can anyone help me with this?BTW, I think I also have a problem with the graphics card driver. When I try to active the 'extra' desktop effects is says this can't be activate. I already tried installing Compiz and the Composite Manager.
I've installed Ubuntu 10.04 on a computer I can't get the wireless to work. I looked into it, and I believe the problem is that I don't have the right driver to work with the wireless card, but I wasn't able to tell what my wireless card is properly. And when I got the bcmwl-kernel-source package and installed it, the driver still didn't appear under "hardware drivers". Compounding the problem, I can't use any sudo commands for some reason because when it prompts me to enter the sudo password, the keys other than "enter" don't seem to work. I probably don't have the right information up there.
my friend loves ubuntu but he doesnt want to switch because he wireless doesnt work he entered all the right details wpa 2 personal and the key but he did not pick up
I have a problem with my laptop's wireless card. My laptop is Grundig GNB-250D. According to lspci my wireless card is a "Marvell Technology Group Ltd. 88w8335 [Libertas] 802.11b/g Wireless (rev 43)".
I can browse the internet just fine if I use an ethernet cable. Also the card worked perfectly on Windows Vista. I tried installing the drivers using Ndiswrapper and it didn't seem to work By the way I followed this guide: [URL]
