Ubuntu Networking :: NM Connects - No Icon / Choice Of Wireless - Error Could Not Connect To Wpa_supplicant
Sep 15, 2010
First- clean installation of Ubuntu 10.04, with default network manager installed, I had a taskbar icon, and it could see the available wireless networks, could not connect to them, even the ones with no security. Purged all network manager files suggested in various threads here, Installed wicd- it could see all available networks, could connect to unsecured networks, but not to my own secured network. Password was correct in the wicd/configurations file. Removed wicd, and reinstalled network manager from synaptic. I have to network manager applet. When I try to add it to the notification area with alt-f2, applet-nm, I get a brief flash of something in the notification area, but no applet.
System=>Preferences=>network connections shows no wireless connections, but I'm obviously connected to something (probably my neighbors unsecured network) since I"m reaching this webpage. I tried to run sudo wpa_cli from the terminal to see what network the computer is connected to, and it gives me this error:

3 computers in the house run various windows based programs and everything is fine with them connecting to the internet as far as putting in the security password to log in and get online.My old back up computer that I use in the basement that has Ubuntu 9.10 was working fine with the secured network situation up until today.I booted up the computer this morning and it automatically connected as it typically does and I was reading some email and then the computer froze, which on rare occasions it does.
Upon reboot I got a window that asked for the password for the Network Manager Applet which I supplied and then it asked for the password for the secured internet connection which I supplied.It would not connect. After numerous tries of disabling the wireless and enabling the wireless and entering the Network Manager Applet password and the secured internet password I still get no connection.
I notice that when it is trying to connect, the window comes up on the screen that shows that there is reception from the modem, but there is also a little "lock" icon like I'm locked out of the connection.I finally found a way to get rid of the Network Manager Applet password problem but that still didn't alleviate the connection problem.

When I run wpa_gui I get a "Failed to open control connection to wpa_supplicant." message and an endless stream of "PING failed - trying to reconnect". I'm sure wpa_supplicant service is running, it also seems to be working correctly (program logs show activity when I connect to a wpa secured network via gnome network manager).
The location that ctrl_interface (in /etc/wpa_supplicant/wpa_supplicant.conf) points to (/var/run/wpa_supplicant) is an empty folder. I'm able to connect to a simple WPA network at home, but the one at my university needs special configuration and I couldn't get it to work by editing the .conf file. That's why I need the gui. My network card is Atheros Communications Inc. AR928X Wireless Network Adapter, the driver is ath9k.

I am trying to connect to my home network which is wpapsk when i click on the networking item in the tool bar at the top it shows my network and when i click on it to join the network it asks my for my security and it only lists wep 40/128-bit key or wep 128 bit phrase or leap?? or dynamic wep(802.1x)
there is no choice for wpa. but when i set up a new network or attempt to edit the network listed under wireless i can see wpa but the system does not connect i have tried looking around for info all with instructions on "enabling" wpa by using wpasupplicant which is there but nothing happens in fact when i try the code sudo gedit /etc/network/interfaces i get command not found which in all the techniques i have tried require this line.

I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

My wireless connection always worked. When I log in, I already have internet access.I went on holiday and connected to several other networks.Now the laptop will not connect anymore. Sometimes after 5-10 minutes.When I forse to connect ("Connect to hidden wireless network), the laptop connects after several seconds. But not automatically.My wireless modem uses WPA2, MAC filtering and has a hidden access point.I use Ubuntu 10.4 on a HP Probook laptop. In "Network connections", under "Wireless", the "Connect Automaticly" and "Available to all users" are selected. When connected, the signal strenght is very good.

I have a Compaq Presario CQ42-195TX laptop with Ubuntu 10.04 (64-bit) installed on it and fully updated. It has a Realtek RTL8191SE wireless chipset which I am having trouble with - its wired connection is working perfectly.After starting up, I am able to see and connect to wireless networks. Once connected, the wireless functions correctly for a very brief period (under 10 seconds) in which I am able to access the Internet and so forth. The connection then stops working - although it doesn't get disconnected. When I say it "stops working", I mean I can no longer access the Internet and trying to ping the router gives me a "Destination Host Unreachable" error. If I disconnect from the network I cannot reconnect, nor can I connect to any other network.- though I can still see the list of available networks.
I thought that maybe this was a 64-bit issue, but I tried the Ubuntu 10.04 32-bit live CD and experienced the same problem.Please note that while this thread is about the RTL8191SE chipset, the RTL819xSE chipsets all use the same driver.Below are the results of various commands while connected to the network but after the connection has stopped functioning correctly:lspci -nn | grep "Realtek"

I've recently installed release 11.04 and am trying to get wireless networking operational. I'm using a netgear wg111t usb wireless adapter. I've installed ndiswrapper and have got the netgear windows drivers installed ok. My problem is when I try to connect wirelessly I get a system crash, think it tends to be called a kernel panic in linux. The network connection is confirmed and about 5-10 seconds later the crash happens. I've updated the linux kernel to 2.6.39-0-generic but thats not helped.
I can connect with a cable but that is somewhat limiting.

I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet

I am using Fedora 8 on my laptop, newly installed, I can see the network card(Linksys WPc54G v2) and Network Manager sees the wireless router, however as soon as I tell it to connect my computer freezes and I have to restart. I searched for solutions but all I found was Ubuntu problems.
Actually it seems that the trigger is when the keyring comes up and asks for a password. As soon as I start typing the pass it locks.

The computer connects wirelessly to a router. The router is connected to the internet and that is working well. (If i use a cable connection to the router, I can reach the internet).
Why wont the wireless connection reach the Internet? It is a strong connection. It worked before wirelessly. I am on 10.04 beta, with the recent updates installed.

Wireless connects fine, then disconnects regularly. I thought it might be an issue with the rt2870sta driver, so I blacklisted it, and it uses rt2800usb now:
Code:

I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.

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 have Ubuntu 10.04 installed on a laptop of mine, and also a desktop. On this laptop, it's a clean install and I'm having a weird issue with the panel on the top of thescreen.ometimes when I start up the computer and login, I get two noticeable quirks. Instead of having the wireless icon in the tray next to the volume, I have two volume controls next to each other.The one icon, that takes place of the wireless icon, is not functional.The other volume icon functions as normal.
The other quirk is that my power button, used for choosing to logout, shutdown,etc,isappears. Instead, it shows two of my username next to each other (one is the legitimate one that lets you set your away status and such). And in place of the power button, is another username menu, but it is cut off by the edge of the screen and doesn't function.Has anybody had this problem before? Is there some kind of package I can update or reinstall to try fixing this? Sometimes the power button will be fine, but the volume icon will still double up.

I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.
I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue.

My wireless (Toshiba laptop, 10.04 64 bit) is just hanging when trying to connect. It was working fine but now nothing. My Wireless antennae is on and my other laptop can connect with no problems. I have restarted the router and the laptop twice.

There's an exclamation point next to my wireless icon up at the top which concerns me. I've just installed Ubuntu 10.04 yesterday - absolutely love it. The only problem is that I'm having trouble with staying connected to my wireless network... When it is connected, there is an exclamation point next to the wireless icon.
I have Broadband internet, Belkin N Wireless router, and an Acer Aspire 5741 with the wireless device built into the laptop. This normally runs fine with Windows 7, but it doesn't automatically connect with Ubuntu 10.04...

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 -
