Ubuntu Networking :: Connecting To A Secure Wireless Network (WPA Or WPA2)
Sep 1, 2011
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've recently installed Lucid Lynx 10.04 on my Dell Studio which uses an internal BCM4315 wi-fi card to connect to the internet. I was hoping it would work upon the install, but deep down I knew I'd have to tweak it a little bit to get it up and running the way I wanted. The card was instantly recognized but, at first, wasn't detecting wireless networks. This was quickly and painlessly fixed using System > Administration > Hardware Drivers, which I used to install Broadcom B43 wireless driver (b43-fwcutter). I rebooted and could not detect the local wireless networks.
I entered my password to my home network (correctly, I quadruple checked) but, unfortunately, it continuously tries to connect to the network with no successful. Occasionally I'm prompted to re-entered the password and the process repeats. The network I'm trying to connect to is a WPA/WPA2 network which I've heard to be troublesome. I haven't yet tried connecting to a WEP network but I'm fairly certain it will work and I will get back to this post when I test it in a few hours.
I'm curious if this question has been answered or if the problem has been solved and I just simply don't have the google skills to find it.

My brother is trying to connect his laptop to his university's secure wireless network and is running into some problems.
He is receiving the following error messages with private info removed:
kern.log
=========
Code:
Jan 13 09:42:52 laptop kernel: [ 91.744131] wlan0: associate with AP
Jan 13 09:42:52 laptop kernel: [ 91.746454] wlan0: RX AssocResp from REMOVED (capab=0x421 status=12 aid=0)
[Code].....
Also, in my research it appears that people that have Wireless problems often install the linux-backports to see if this fixes the issue.

I keep getting a "bad password" error message when trying to connect via wpa_supplicant to a wireless network (Apple Time Capsule WPA/WPA2 mixed).
Here's my wpa_supplicant.conf:
Code:
And the relevant line in the /etc/network/interfaces file:
Code:
The Time Capsule log contains the following error message--
Code:
So perhaps the password is somehow getting lost in translation from Ubuntu to the Time Capsule?

I've been having a network problem that I've been able to temporarily solve by rebooting the router, but even that can be shaky at times, and it can sometimes disturb others' internet activites, so I'd really like to tackle this while I can. I had an old thread about this, but it's ancient history by now, and plus which, I've got a bit more Linux experience and patience than I did before.
The basic problem is that NetworkManager will associate and connect to my home wireless network, but a) it won't let me ping the router or anywhere else ("Destination Host Unreachable"), and b) the connection lasts for maybe a couple minutes at most. If I reset the router, however, 9 times out of 10 it will associate and connect successfully and I can get online, but I have to run a constant ping to the router with a 10-second interval, otherwise it drops the connection, unless I'm doing a lot of other heavy network activity.
ping 192.168.1.1 (the router):
Code:
I've tried wpa_supplicant, but this is what I get (it's apparently unsuccessful...? ESSID/MAC addresses censored where necessary):
Code:
The last prompt line is included because I cancelled it myself; it didn't abort on its own. If left unmonitored, it basically keeps doing this over and over, with no visible network activity at all.
With NetworkManager, I can keep selecting the network's ESSID over and over, and it seems to reconnect, but I still can't ping out anywhere. I'm using a Netgear WN111v1 wireless adapter with ndiswrapper and the Windows drivers. I have no idea what the chipset is, and I doubt that Linux drivers exist for it, even if I knew what it was. The router is using WPA2 security (hence my trying wpa_supplicant)
lsusb:
Code:
ifconfig wlan0 (while connected; IP/MAC addresses censored where needed):
Code:
ifconfig wlan0 (while not connected; IP/MAC addresses censored where needed):
Code:
Code:
I only include this for format checking purposes. The commented out "psk" is the actual text passphrase, while the uncommented one is (presumably) a hex representation of the same key. Is this correct? I've never done this with wpa_supplicant before, I've only used NetworkManager (which is a pain in the @$$ because it requires X to run, and so it disconnects any time I log out/back in ).
Is there any hope of getting my wireless connection permanently working, so that I don't have to reset the router every time I need to reboot or log out/back in?

I have a Dell Inspiron 8600 laptop on which I recently installed Ubuntu 9.10. Most things work, but the wireless will not connect to my home wireless network (a Linksys WRT54G). (Cannot see any other WIFI antennas from here, so I don't know if it works on other networks). Ubuntu says I have an Intel PRO/Wireless 2200BG, Kernel Driver ipw2200.
When I try to look for a wireless network, Ubuntu doesn't see any. (Every other computer in the house does, Macs and PCs). I tried Connect to Hidden Wireless Network > New > and filled in the name and the WEP password that the Linksys gave me.When I select Connect to Hidden Wireless Network and select the network that I entered all the information for, the Connect button is always grayed out.

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 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.

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 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?

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 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 another slight issue. On a clean install of Ubuntu Studio (10.10), I have installed network manager (manually, using .deb packages, one at a time, including all the extra ones it required) and I can only connect to non-secured networks. If I try to connect to our home network (which has WEP security), it sits thinking about it for a while (with the wireless light flashing, indicating it is doing something), but after a while, it asks for the WEP password again. it works fine if I turn the security off

After updating to 10.04, I was able to connect easily to my network. However after getting a new router "Linksys WRT610Nv2", I was initially able to set up my wireless "WPA & WPA2 Personal"-encrypted network, but for whatever reason it stopped working completely.
My Asus EeePC 1000H does recognize my network, but its does not want to connect anymore, whatever I try. If I use no encryption, or go wired, everything works well. If I go on other networks everything is ok. I even reinstalled Passwords and Encryption Keys. Other computers (Windows-bad XP and Vista, laptop and desktop [sorry, but working on it to get rid of them!]) have no problems, either wired or wireless connecting with my network. Booting under 9.10, everything works ok as well. In Ubuntu 10.04, going into Network Connections and Edit my network, this is what I see:

The university I go to uses a WPA2 wireless network that requires a netID and password to connect too. I installed wicd but I can't seem to connect to this network, is there a way to add this functionality to wicd, and if so, how do I do that (links to a how-to or guide would be nice, I've yet to find one).
Also, I spend most of my time on campus in the command line, so I'd like to know if there is a way to use command line utilities to connect to this network (again, a guide or how-to would be nice)
I can get online through my fedora live USB just fine (w/ network manager) but I'd rather get on directly from slackware.

Well I recentelly read some tutorials about "cracking" wep networks, and seems like it's kind of easy ( I Haven't tried'em out since I don't have my laptop right now, but i'll try them as soon as i get it back )So i'd like to change my network protocol to wpa2, but I REALLY GOT NO IDEA on how to do this.Does someone knows about a tutorial on how to do this?

I've got a BCM 4312 card on a Dell laptop running 10.04 and an Apple Airport network. Since I configured the Airport to use "WPA2 Personal" Authentication, my connection is flaky: it drops for no apparent reason and sometimes I can't connect at all. When authentication is turned off, the connection is rock solid.
Here's an example from the syslog of a failed attempt to connect:
Code:
Oct 26 19:31:24 firefly NetworkManager: <info> Activation (eth1) starting connection 'Auto Rittenhouse'
Oct 26 19:31:24 firefly NetworkManager: <info> (eth1): device state change: 3 -> 4 (reason 0)

I wanted to run a little media server in my house, shared with my laptop only, so I could free up space on my laptop drive. I took one of my Linux boxes out of my render farm and loaded up a minimal install, command line only of Ubuntu Lucid from the mini ISO (32 bit). I had to plug in a lan cable to install, but I wanted to move my box back out to the "farm" that doesn't have wired access to my intranet.
After much research, trial and error, this is what worked for me. My wireless card uses an Atheros AR5001X+ chip, and it works with the desktop cd out of the box. I found the "just works" desktop install uses the ath5k driver that is now included in Lucid, but I'm not using a desktop or window manager. I haven't tried this on server version, if you do, let others know what you had to install to get it to work.
The things I do tell you about, I instruct you as if you are a newbie, however I have left out some things that users should know or be able to lookup easily, like if you want a static address instead of using dhcp. You may not need all of the steps or you may have to do more research and troubleshooting.
Find your wireless card (you may need to lookup what to do if it is not recognized at all)List all pci devices, only show network devices (-v verbose, -vv very verbose): >>lspci -vv | grep Network List all hardware (| less lets you pause at each page - arrow keys, page down/up to navigate, q to quit) >>lshw | less

My college runs a WPA2 LEAP secured wireless network, and I am having problems connecting to it under Ubuntu. I can connect to it just fine under Windows, just not under Ubuntu. Under Ubuntu I can connect to other networks such as my home WEP secured wireless network, so it shouldn't be a hardware or driver issue.
When I do connect to the WPA2 LEAP network it recognizes the network and tries to connect, it pops up the login box for me to enter my username and password, but after I click connect it pops back up again about 10 seconds later. It pops up like this about 3 times total, then after the third time it stops trying to connect and the Wireless Network Disconnected message is shown.

I just installed Ubuntu 10.04, everything is fine, but the wireless. When I try to connect to my WPA2 protected network, it is grayed out. SO I click Connect to Hidden Wireless Network, and this window pops up. I put in my network name, the security type, and password. It acts like it is connecting, the wireless icon is going up and down. But then another window pops up, saying Authentication required by wireless network and the down arrow is grayed out.

I am using the Fedora 13 Live USB on my Gateway MT6451 laptop. All the major things you want to work on a laptop with linux actually work! Even my Broadcom wireless card! But even though I can see wireless networks and connect to ones that are open with no problem, I can't actually connect to my Hidden WPA2 network. I put all the information in and it connects, shows a good signal, but doesn't acquire the correct IP. I have a 192.168.X.X address range on my network, but it shows a 10.X.X.X ip and no Gateway address.
If I can get this one thing working I will definitely be installing Fedora.

O currently have 2 USB WiFi adaptors: a Linksys WUSB54G v4 and a D-Link DWA-110. Both these USB adaptors worked extremely well in Windows: they could connect to any network: unsecured, WEP and WPA1/2I have tested these adaptors in DreamLinux, OpenSUSE and Mandriva: in these 3 distributions, i could use both adaptors to connect to my home's WPA2 network.Both adaptors also work well in Fedora 10.In Fedora 11 Alpha though, its a different thing: only the D-Link is able to connect to the home WPA2 network. My Linksys WUSB54Gv4 can 'see' the network, but when i enter in the WPA2 key, it takes forever to try to negotiate a connection before timing out and disconnecting.

I have a problem with my RT2860 in my Eee PC 901 running F13. It connected fine in F12 when I installed the akmod-rt2860 driver. I enter my WPA key, then it tries to connect, but the WPA key screen appears again saying that I may have typed in my WPA key incorrectly. However, I checked and it is the right WPA key.
