Ubuntu Networking :: Laptop Unable To Connect To Wireless, Wired Networks?
May 28, 2010
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 am a beginner to ubuntu. I have installed ubuntu 10.04 on my laptop using wubi.When I am trying to edit the IP address using network editor,apply button is not highlighted.I managed to give IP as well as netmask through command prompt.But I am not able to give gateway and dns IP.Please help me configuring this.
My laptop has been working fine with ubuntu 10.04, and earlier today it shut down after running out of battery. I came to use itr and discovered that the wifi icon had disappeared from the panel bar, and it won't connect to the wireless networkor via a wired connection.I have had a play around with this, tried ping -c5 google.comresult was:ping: unknown host google.comand ping -c5 4.2.2.1result: onnect:etwork is unreachable.I have other computers connecting to this network and know that it is working fine.
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."
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 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 am unable to connect to any network, wired or wireless. Network-manager and wicd are both gone, as in no longer installed. Please don't tell me to apt-get anything. I have no network connection. I have tried downloading packages for nm onto a usb stick only to find myself in dependency hell which ended with the impassible error "Requires installation of untrusted packages".
i have installed fedora 15(lovelock) on my lenovo z560 ideapad laptop. in fedora 15 lovelock internet is not working by wire or wireless. Network controller: Broadcom Corporation BCM4322 803.11a/b/g/n Wireless LAN Controller (rev 01)

There are two networks in house I rent with other roommates. One wired, the other wireless (two separate routers), long story of why it worked out that way. For some reason, I am getting the same ip on eth0 and wlan0 even though both connections come from two separate routers, see below:
My setup is above, I hope it comes out OK on this forum, and someone can understand what its supposed to be! My problem is I am not sure how to get [PC] to be able to see [Internet]. From [Laptop] I can get both networks to work, and have tried using brctl to bridge them, but as soon as I do "ifconfig br0 up" neither network... works anymore (cant ping either router).
I have recently installed Ubuntu lucid lynx and at my old house I had a regular cable modem (no wifi) and never used wireless internet. I would simply unplug the ethernet from the windows desktop plug it to my laptop and I was good 2 go.have recently moved and my roommate has a cable modem w/ wifi capabilities. When I plug in I am told that I am connected but......Nothing. dont know if the problem is due to the modem having wireless capabilities when my old one did not or the fact that my roommate has a win7 laptop that is connected via wifi etc. There have been a FEW times that I have walked out plugged in and everything has ran well. when I do plug in I look under connection information and I am told that I am connected at 100Mbps but whenever I try to visit a page I am out of luck. I define newbie (as far as Linux distros) and I have tried everything including going to work w/no sleep because I'm going through massive trial & errors
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.
After upgrading from 10.10 to 11.04 and running an update ubuntu can't connect to any wifi networks, although it can see them perfectly (and potentially unrelated, the windows partition is having major dns issues with the wifi too).
I've looked around and can't find an obvious fix, just a bunch of posts from people with the same problem that wasn't solved. I got frustrated and was about to install 10.10 again but I noticed I couldn't connect to the wifi on the liveCD either. I then tried the 10.04 liveCD, and the internet worked aswell as when I installed it. However before when I upgraded from 10.04 to 10.10 I had no problems with the wifi, so it leads me to suspect that there was something installed/some setting in 10.04 that is missing from the latter version.
I've just installed 11.04 Natty on an old Laptop (Dell Lattitude C400) and am unable to connect to my home network (wired LAN connection, no wireless). The laptop previously had WinXP installed and was able to connect (I have also double checked the cables and ports and they're all functioning ok).
in linux world and have recently downloaded and installed ubuntu desktop 10.10i cannot connect to both wired and wireless ethernet on my laptopit tries to connect but fails in 30 seconds , it says"disconnected" while i am able to connect to the same in windows i have broadcom 4315 and i have tried both fwcutter and ndiswrapper but the problem persiststhe device id is 14e4:4315
I want my netbook to connect automatically to both the office wired/static network and to the usual wired/DHCP networks.
wicd is wicked but netsearching hasn't revealed how to configure it for both wired/static and wired/DHCP except by manually switching profiles.
wicd's profiles can use pre/post(dis)connect scripts but I don't know how to integrate them into wicd when they are upping/downing connections on cable (un)plugging.
If it is not practical to solve this within wicd, I'll explore standalone scripts to configure eth0 on cable (un)plugging, as detected by ifplugd.
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'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 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.
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?
I have not been able to get an internet connection wired or wireless on my laptop. I downloaded the drivers from Acer's website and tried installing them using ndiswrapper. Still no luck.
