CentOS 5 Networking :: Connecting To A Wireless Network Using Encryption?
Apr 5, 2009
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 would share my long awaited success with connecting my ubuntu laptop up to my universities (University of Western Sydney) wireless network. The rumors appeared true and they have finally implemented 802.11x authentication instead of that horrible java app netdirect. I am sure you've been cursing at its erratic stability. There is no linux documentation for airUWS-Lite nor anything more imformative than there windows/mac point and click steps found at [URL]. However with a few simple clicks you can have stable working connection.
When connecting make sure you have theses settings.
Security: WPA & WPA2 Enterprise
Authentication: Protected EAP (PEAP)
#This is the settings that does not present itself correctly
Anonymous Identity: leave blank
PEAP Version: Automatic
Inner Authentication: MSCHAPv2
Username: <YOUR 8 DIGIT STUDENT NUMBER>
Password: your regular password

I have a fairly new install of 10.04 on a Dell laptop (about a week). Everything was running well, connecting wirelessly to the interneet through my home router (WPA/WPA2). Today, for some reason, I lost my connection to the internet. The network manager tells me I'm connected to my router, but all the lines on the wifi indicator are gray and there is no internet access. I reinstalled the 2 sets of packets for my BCN4312 (bcmwl-kernel-source and b43-fwcutter ), but no change.

I'm having problems with my wireless card. The network manager won't allow me to turn it on. It is working in windows and in ubuntu, but I can't get it to turn on under fedora. I'm using a Lenovo B570 laptop and it uses the Centrino Wireless-N 1000 for wireless.

I noticed that it takes a couple more seconds before Ubuntu connects to my wireless network when it wakes up from sleep. I didn't have this annoyance when I was using 10.04, and only appeared when I upgraded to 10.10. It takes about 5-7 seconds before it indicates that it's connecting. When I was using 10.04, it only took a maximum of 2 seconds for it to indicate that it's in the process of connecting to my network.

i just installed Ubuntu 11.04 64bit on my desktop. i have a TP Link TL-WN321G (Ver 4.0) wireless usb adapter to connect to my wireless network (i used to use it with Windows XP).As expected (i'd read up a bit before installing Ubuntu), the adapter was autodetected - i could see my wireless network listed in the networks list dropdown, and lsusb showed it too.lsusb identifies "Bus 002 Device 002: ID 148f:2070 Ralink Technology, Corp. RT2070 Wireless Adapter"But i cannot connect to the network. When i select my network, it keeps trying to connect, but never succeeds in connecting.
i tried going through the forums for possible solutions, but most of them deal with how to get it working when the adapter is not detected, or when networks are not shown. Or they are for older Ubuntu versions.i use the same wireless network on my laptop (Ubuntu 9.04), and it has a WPA & WPA2 Personal security, with a password, which i've configured in the desktop as well.

I have a wireless router, but my desktop computer is connecting to it, or maybe to the modem, by an Ethernet cable. It has a built-in wireless card, so just as an experiment, I tried to connect to my network wirelessly. It didn't work. And not only did I not get any internet connection, I can't get any internet through the wired connection either. The internet works fine with Windows Vista (I'm dual-booting), as well as when I boot up Backtrack off of a Live DVD. I can still access my router's config page by going to 192.168.2.1 on a web browser, but I can't access anything else.

In setting up wireless connections I have ran into an array of problems. First, when I installed the new OS on my laptop I had to get the correct drivers and firmware for it to display and connect to any connections, had no problem here connecting to a secure wireless network (WPA or WPA2). I then installed Ubuntu on my desktop and had to find the correct driver for the Netgear WNDA3100v2 USB adapter, got it all installed with the Windows Wireless Drivers tool or w/e it is. This made all the available connections come up. I tried connecting with the WPA password I was given for the network and will not connect.
I had the guy managing the network change the one I connect to, to a WEP Passphrase Shared Key thinking this would solve my issue, still nothing. And also in doing so, now my laptop will not connect to the wireless network using the Passphrase. I do not want to go back to Windows, and I will be getting rid of my Lan connection soon so i need a solution to fix this wireless connection problem.

I am trying to do a command line installation.Finished the installation and my wireless card wasnt working.Did a "sudo ifconfig wlan0 up" and got it working.But for some reason wireless-tools is not installed thus I dont have iwconfig, iwlist, etc.The wireless works and connects fine off a liveUSB.So I am going to give info from this liveUSB run and maybe someone can suggest how I can set the right settings on the Command Line Installation I presume in the etc/network/interfaces.

I'm having a bizarre problem with FTP transfers from my CentOS 5.3 boxes, All of my CentOS boxes appear to be limited at ~10kb/s when connecting to any FTP server outside of our network. We have no network infrastructure which would cause this, however when I use a windows based machine it is able to connect fine.
I took my laptop running Vista, and rebooted it onto a CentOS 5.3 LiveCD, and same issue.
I have checked our iptables, cleared the rules, removed the kernel modules, checked CBQ/TC it looks like nothing is limiting this. Also, other protocols work fine. Both the windows and linux boxes used passive transfers for it.
Is there anything other than iptables/CBQ which would be on a out of the box install of CentOS I should check? Is there any kernel settings for NAT connections which may cause this?

I followed [URL]..to set up my wireless network with WPA2 encryption. It works now and knemo says:Encryption: active. However, "iwconfig wlan0" says Encrytion key: off:
Code:
wlan0 IEEE 802.11abgn ESSID:"blitz"
Mode:Managed Frequency:2.472 GHz Access Point: 00:25:9C:DE:D3:7D
Bit Rate=0 kb/s Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
[Code]...
So is there anything wrong with that "Encryption key: off" statement? I suspect that encryption key only applies to WEP, but not to WPA2 encryption, but I am not sure. So my question is, can I ignore that statement and assume that my encryption is fine?
Besides, where does knemo read the information about encryption from? As I mentioned, knemo detects that the encryption is active. Are there any other commands to make sure that my encryption is safe and well?

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 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'm having some trouble connecting to the wireless network here at home. The PC has a Linksys WMP600N wireless network card, which works fine under several versions of Windows. In Opensuse however, I cannot get it to find the network. Even though my laptop is right next to it, which has perfect connection to the network. The router is a Linksys WRT610N.
I've tried running iwconfig and iwlist scan in the terminal, but the scan returns no results and iwconfig indicates it does not have a connection to a network. I've turned off IPv6 as I read this can sometimes cause issues. I've also tried issuing the computer a static IP address, figuring the DHCP might be causing problems, but all to no avail.

since a few weeks I have a problem connecting to other hosts when I'm using another wireless network, which has a different DNS IP than I have in my network. I have to change /etc/resolv.conf to change the nameserver. Can NetworkManager control the nameserver? If yes, how?

enable WPA encryption on my wireless connection? Wireless networks are detected and listed, so the wireless card is functional in the most basic sense, however, when going to connect to any particular network,I am not given the option of entering a WPA passphrase, only WEP, and as my router is set to use WPA, this is a problem.I am trying to get this going on a fresh Karmic install on a Toshiba A15-S157 notebook.Thus far, I have found this: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/315489 which would seem to relate to my problem.I looked in my logs and saw this entry: Jan 10 16:06:35 cody-laptop firmware.sh[863]: Cannot find firmware file 'agere_sta_fw.bin', and have since found that file, and have downloaded it to my desktop. It seems like this may be the solution, but how to exact it, therein lies my (momentary) problem.

Using sudo iwlist scan, i will get a list of surrounding AP(s) around my laptop, is there a way to interpret the sudo iwlist scan results so that we can know what encryption type is the wireless network using?

I am having some trouble getting my computer to connect to my wireless network. There is a wireless icon in the system tray. When I click on the icon I get a list of SSIDs associated with available wireless networks. To connect to one of of those networks I move the cursor over the SSID, the SSID is then highlighted, I select the highlighted SSID, then my computer connects to the selected network.
Sometimes the SSID associated wth my wireless network does not show up on the list. Sometimes it does. Normally the SSIDs on the list are in bold lettering. When the SSID of my network does appear it is in shaded lettering. When I move the cursor over the SSID it is not highlighted and I cannot select it. So you see it is not possible for me to select the SSID of my network and connect to my network.
The computer I am running is a ThinkPad R40. This is the wireless controller on the computer. I got this with "lspci". 02:02.0 Network controller: AIRONET Wireless Communications Cisco Aironet Wireless 802.11b

I am having trouble getting my wireless card to connect to my network. I believe I have done everything correctly. Here is my wpa_supplicant.conf file:
Code:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
[Code]....
I have never connected to a wpa network using slackware before, so I am not entirely sure how to use wpa_supplicant. I have altered the conf file, then tried dhcpcd and it times out.

I just bought a new USB wireless adapter for my openSUSE 11.3 laptop, a TP-Link TP-WN727N. I can't get the new card to connect to my home wireless network, which is named WRT320N in the screenshot. KDE prompts for the key repeatedly but never connects successfully. Part of the problem might stem from the fact that this laptop now has 2 wireless cards: one build into chipset (PRO/Wireless 3945ABG) and the new USB card. Both show up in knetworkmanager but no clear distinction is made between them visually. Strangely my wireless network shows up twice in knetworkmanager as in the screenshot. Once per wireless card? As my wireless network is N-only I don't see why it would do this.

Just moved over to openSUSE 11.4 (KDE) from Ubuntu, yesterday. However, I'm having some trouble with my wireless connection.
I have a wireless network with a hidden SSID and WPA2-PSK security. I entered all the nescery information into the KDE network manager, but it couldn't find my network. So I ran the usual command:
Code:
su -c iwlist wlan0 scanning essid [My SSID]
At which point, the network manager immediately found, and connected to, the network. However, it seems that I have to run this command (as root) each time I log in, before my laptop will connect to the network. The network manager has no problem find the plethora of unsecured networks as well as those that are secure, but broadcast their SSID.

I am running Fedora 13 and using Ndiswrapper with my pci wireless card. my router is a netgear wgr614v9 wireless router with wpa2-psk. When I try to connect to my network the only options I see for security are dynamic WEP (802.1x) and WPA &WPA2 Enterprise and for authentication all I see is TLS LEAP Tunneled TLS and Protected EAP (PEAP). I can connect to my network when I drop security on the network but other wise I am stuck. I have been trying to fix it for about a week now by myself to no avail

I've spent 29 hours trying to figure this out. And I'm about to blow my brains out. Fresh install 11.2. - 64bit but tried 32 bit and same thing. Dell studio 1734. Broadcom wireless and wired. Installed broadcom drivers (b43) through yast. Wired eth0 works. Wireless eth1 works. Surf with Firefox fine. BUT. Kmail will not connect through wireless. Nor can I access repositories through wireless.
Tried blacklisting B43 in ssb no change. What in the hell is going on? I've searched forum after forum and tried everything and CANNOT make this happen.

I run Ubuntu, and it has a nice GUI widget thing that connects me to my home wireless network when I boot. I don't have a problem with that. But suppose I don't start X, and boot to a recovery console for some reason, like I did recently when my graphics were broken after installing Karmic. In that case, my computer won't be connected to the wireless network until I log into X normally. So I can't apt-get anything or anything. It's very annoying. And I don't know how to connect to my wireless network.
I know my wireless network SSID, and I know my WEP key or WPA passphrase. How can I log onto the network with commandline tools? Is there some basic program that I can just run "networkmanager <myssid> <mywepkey>"? I looked at the iwconfig man page and I honestly couldn't figure out how to simply connect to my network. Once I figure out how to connect to the network with command-line tools, where can I put an "autoconnect" script so that it will connect during startup, like it should anyway?
What I don't understand is, why the Ubuntu network manager nm-applet, doesn't just work as a front-end for more basic networking stuff. I don't see any reason why it should require you to start X before working; it could be a daemon that runs at startup, and there could be a config-file somewhere, but it doesn't even start running until I log onto gnome.
