Ubuntu Networking :: Unable To Connect To Secure Networks
Nov 12, 2010
I have been using Ubuntu for quite a long time and I never got around fixing this particular wireless problem. I have tried Network Manager as well as Wicd. I am never able to connect to a secure network (WPA). When I use Network Manager, it just tries for a long time and gives up. As for WiCD, it again tries for a long time and finally says "Bad Password". Of course, the passkey is correct. When I connect to an unsecured network, it goes through just fine. I have a Dell Inspiron 1545 which uses a Broadcom 43xx Driver.
I recently ubgraded to ubuntu 9.10 from 9.04, but I had the same problem there. I can see the secure connections, but when I try to connect to them, it tries to connect, works at it for about a minute, and then asks for the password again. This just started a week ago or so. I am new with ubuntu, so while I know that there are terminal outputs I should probably post, I don't know which ones.
I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
I've managed to install my WUSB600N on 10.10 (which was NOT easy!!) and I can see all my local wireless networks, but I can't connect - it attempts to connect then disconnects after what I guess is timing out.I know that you can place these cards in broadcast mode (I think), where you can see networks but not connect. Considering that to get this card working I had to attempt about four different sets of instructions to get this far, could I have placed the card in a broadcast mode? I've been at this for about three days, and unless I go out an buy another network card (I'm currently connected using it through windows) then I'm going to have to give up on Linux, which I really don't want to
I have a Toshiba NB300 netbook that has an Atheros AR9285 wireless chipset and is running Ubuntu 10.04 Lucid Lynx. At my University there is a FreeRadius authenticated wireless network (called "UCC") that I would like to connect to. Using NetworkManager I have created an automatic profile called "Auto UCC" that contains my user details for the connection. When attempting to connect to the network, the NetworkManager icon spins for a couple of minutes and then presents me with the authentication dialog. If I re-enter my details (and disable the CA cert prompt), it repeats the process seemingly infinitely (spin-spin-spin, auth box) Attached is a copy of the syslog from first attempting to connect to stopping the connection attempts. The wireless card's 'lspci' line is
New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.
I'm trying to install Ubuntu 10.04 on my Toshiba A200-12U laptop (with an Atheros AR5007EG wireless card), but networking is being problematic.I entered Network Configurations and tried to get 'Auto eth0' working -- I went to Edit > IPv4 settings and filled in 'Addresses' with the details of my connection:
Address: 192.168.1.254 (the local IP of my router) Netmask: 255.255.252.0 Gateway: 94.195.208.1
I'm running ubuntu 9.10 on my desktop.Wireless networks appear on the dropdown menu but when I try to connect to my home network the authentication box appears, after typing my password the box disappears and it continues to connect but nothing happens and after a while the authentication box appears again. So.. no internetz connected.
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
While staying at a hotel that offered wireless Internet connection connection I was not able to access their network. I contacted their technical support 800 number and was told that the north building server had been down for 26 hours. I moved to a south builing room. Same problem. I went to McDonald's, which had wi-fi connection. Same thing. My laptop was not able to make a connection.
My question is as follow:
How do I find out:
1) whether it is a problem with my new Ubuntu version (10.04)?
2) my wireless card in my laptop is no longer working? Are there any tests that I can run?
I installed wheezy on my Acer Aspire One netbook and am unable to connect to wireless networks.Output of lspci shows this as my wireless card:

02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) I installed the firmware-atheros package to get the card up and running. Output of iwconfig shows I have a working interface:Quote:

My wireless network is being detected but it refuses to connect to it. I am entering the accurate passcode and I have tried doing various commands for it to work, but it is being stubborn.
Also, it would help to know which WEP Index to use and type of Authentication.
I have an hp dm1z and ubuntu 10.10 64bit. After I suspend (close the lid) and wake it up (open the lid) at a different location with a network connection (wired or wireless), my system always fails to connect. I need to reboot and then it sees the network and connects fine. I have tried /etc/inet.d/networking restart, but nothing changes. The only exception to this rule are two networks that have WPA security settings and are stored. I can always switch between those two. I have tried ifconfig eth0 up & down and restart networking. I have also tried to connect manually (dhclient) and no success. None of these work. I am including the output of lshw -C network.
I have an MSI Wind U100 netbook running Maverick, and it has a Realtek RTL8187SE Wireless controller according to lshw. My computer can "see" some wireless networks where they are present, meaning when I click on the little network icon at the top of my screen it shows the available networks. But when I click on them to connect, the icon does its little "connecting" motion, but I never receive any message saying "Connected" and when I open Firefox and try to browse to google.com, it says "Server not found"
I have an ethernet card connected to my LAN and a USB cell modem internet connection. I am running ubuntu 10.10. The problem is this: I can use either network, but only am connected to one of them. If I connect to both at the same time my speed drops to zero.f I disconnect one, the other starts working. I have done a lot of searching and reading, but it looks like I don't know how to find what I am looking for.My LAN was setup as 3 WinXP computers peer to peer. One of those computers was replaced by this one that I am having trouble with (computer A). Another one was replaced by one that is not yet on the network (computer C).Computer B dual boots Win XP and ubuntu 10.4. Mostly it ns xp for Quickbooks and BobCAD, also it is connected to the printer. My router is setup for DHCP
I used to be able to connect to my uni secure access vpn by navigating to the appropriate page, logging in and clicking "start" by "Network Connect" etc. etc. After an update to firefox it had been failing, giving me a "session timeout" MsgBox. I have tried clearing history etc and reinstalling firefox. I have also tried different browsers with no success.
So, I have since upgraded to 9.10 and now I get "Setup Failed, Sorry" in the bottom left of the screen (where "Done" is displayed once a page has loaded)...
I am now trying a different approach. I have downloaded ncui-6.5R2.i386.rpm and unpacked it fine. I have tried running it, without success and have also run the diagnostic - I will post results below:
When I try and run ./ncsvc I get the following:
Code: ncsvc> Failed to setuid to root. Error 1: Operation not permitted
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.
We have two networks,one is 10.0.0.* with mask 255.255.255.0 & the other 20.0.0.* with mask 255.255.255.0 and one linux(RHEL5) PC with two network interface eth0,eth1.(configured as Router) eth0 is 10.0.0.1 and eth1 is 20.0.0.1 we have enabled IP_Forward using "sysctl w net.ipv4.ip_forward=1" cat /proc/sys/net/ipv4/ip_forward is 1 but unable to ping from one network to other network.
two networks are connected to Linux PC.(10.0.0.1 & 20.0.0.1)
still wht configuration required to establish the connection between two networks using LINUX PC.
from router(linux PC) both network PC's are pinging but not from one network to other network.
1) I connect to the internet on a wireless router from my isp.
2) I use an older router for my media server (pc) to my ps3. The router given to me from my isp is the only one I can use to connect to the internet, yet it has the worst UPnP support (ie: none).
So with this current setup, I have to disconnect from the the wired network to be able to access the internet. So how can I access the internet while still connected to the wired network?
I have a machine running Xubuntu [2.6.22-14-generic]. I have been trying to get this machine connected to wireless for ages, and I'm having another stab at it. So far I have install ndiswrapper and loaded the driver for a Linksys wireless adapter. The output of 'ndiswrapper -l' reports:
So as far as my newbie knowledge goes, I believe that step to be completed, correct?When I turn on the machine is type in
Code:
sudo sh modprobe ndiswrapper
to get the card running to where it will appear in the iwconfig dialog.The commands 'iwlist wlan0 scan' will list all the wireless networks around me, but I have been un-able to connect to any network, even unencrypted ones. I have tried to connect both through Wicd and command-line to no avail. For command-line I have used:
Code:
sudo ifconfig wlan0 down sudo dhclient -r wlan0 sudo ifconfig wlan0 up
[code]....
With the final 'dhclient wlan0' commands, the following is returned:
Code:
There is already a pid file /var/run/dhclient.pid with pid 134519120 Internet Systems Consortium DHCP Client V3.0.5 Copyright 2004-2006 Internet Systems Consortium
[code].....
I have attempted to go ahead a step further and connect to an encrypted wireless network, however, I receive the same message, as well as another error message upon trying to enter the key, with the following code:
Code:
iwconfig wlan0 key s:"thekey"
Error for wireless request "Set Encode" (8B2A) : SET failed on device wlan0 ; Invalid argument.
I have an Atheros AR242x card. It can see my wireless network (WPA2). When i attempt to connect to the network it asks for the WPA2 passphrase. After entering the password it begins connecting but hangs up for about 3 minutes before saying wireless disconnected. The wireless worked for one day on a fresh install (Ubuntu 10.04)and then started doing this.
I have a WLAN Driver Azure Wave AW-NU222 Wireless LAN Card in my Medion computer.
After installing Ubuntu it seems to detect the wireless networks in my area. However, when I try to connect to my network, it tries for several minutes and then times out with no error message. I have set up the credentials and also tried removing the encryption (WPA-PSK) from the network itself, but it still doesn't connect.
Connect via an Ethernet cable is fine, and I know that the network is good because I can connect via my Windows Laptop and various other wireless devices.
I suspect it's due to drivers, but I'm having trouble downloading a driver which I can try and install using Ndiswrapper. The Medion website just a windows executable when I try and download the driver specific to my machine when I really need the .inf file.
Here is a situation I have never come across (though I have only been using linux since 2004).I am running ubuntu 10.04 and using Wicd Network Manager.I can connect to my WPA encrypted home network, but if I go to my coffee shop to use their unencrypted wifi - I cannot.Even using the terminal. I think it is the way the device sees the network - but I don't know how to fix it.I have a screenshot with wicd here:And one with connecting to the essid here:Afterwhich, dhclient was unable to obtain an ipaddress - just like wicd above.
My iphone connected to this network easily without encryption or needing to use the browser to authenticate, etc.Any ideas on how to fix this?Specs:Samsung NC10lspci:
I have a HP Mini1000 and recently switched over to Ubuntu. I followed the directions found here:[URL] However, I still cannot connect to wireless networks though my card seems to be scanning for them and finding them. I have tried connecting to open networks and ones that require authentication.
I have an Eee PC 1015PEM with Ubuntu 10.10, I believe the wireless card is an rt3090 (though sometimes I see references to rt2860).I had problems getting this to connect to any wireless network originally but eventually was able to fix this by blacklisting a number of modules.However I am still unable to connect to hidden networks and have not been able to find a solution.
Got Ubuntu 11.4 installed on my Lenovo Thinkpad X220.Except very very rare cases i'm not able to establish awlan connection.Scanning is possible at all times, monitor mode works as well.Network Controler (lspci)
So I was the one who couldn't get their ethernet port to function properly. Most likely, this was the result of bad hardware since none of the community's suggestions for software fixes did anything. I believe this is probably true.Indeed, when I bought a cheap $10 wireless USB dongle, it immediately worked better than all the previous things. It detected networks, displayed network strength and even allowed me to attempt login.
The only problem now seems to be that it cannot login. I've rechecked the password countless times, but it just shows the 'connecting to wireless' animation for a minute or two and then poops out and says, 'disconnected'.I assume if everything is getting me this far, the driver is not the problem with the device. Is this a safe assumption?
