Ubuntu Networking :: No Wireless Connection After Upgrade To 10.04?
May 5, 2010
NOTE: My upgrade wasn't smooth. Now everything is extremely slow. However if I boot from the disc to try without installing, the connection problem is still there. There is an exclamation mark on the connection applet, right clicking shows that Enable Wireless is unchecked and unclickable. I've included outputs of common network commands which might prove to be useful.
Code:
[~] ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:33:60:f0:3c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I have an odd problem in that my wireless connection is okay until I close the laptop. When I open it back up, I'm unable to reconnect. This problem first occurred after upgrading to 9.10. I can reconnect after restarting. I tried several things before breaking down and reinstalling 9.04. After installing 9.04, everything works great. Any suggestions on what is going on before I try upgrading to 9.10 again? I have a Dell D600.

Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.
I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.

Ok, so I upgraded my acer aspire one to the new Ubuntu 10, and at first everything was working fine, except the audio. Now, for some reason, my wireless and ethernet ports have died. I can't get online by either method. I can do ifconfig <device> up and it will show up if i do iwconfig or ifconfig, but the wireless isn't associated with the AP. Currently I'm trying to load some drivers for my atheros card, and we'll see how that works outReally I was wondering, how come the modules don't load at boot time, and how can I fix this? I've been a Linux user for quite sometime, however I've been more of end user

A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.

I've got an old Compaq Armada E500 laptop (850mhz PIII, 512mb RAM, 30GB HD) that I've been running OpenSUSE 11.1 w/Gnome desktop. My wireless adapter (Linksys Wireless-G, model WPC54G ver. 2 w/acx-111 chipset) worked well with this setup, but no that I've upgraded to OpenSUSE 11.2 w/KDE, I've got to start all over. I tried doing what I did before, which was to copy the firmware file into /lib/firmware.

Can I upgrade from Fedora 9 to fedora 10 from a wireless connection? What I want is to upgrade without using a cd or usb device. I would like to use yum or packagekit. Can it be done? I just don't have any device or cd/dvd with me.

I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.

I have a Dell Mini 9 with a Broadcom wireless adapter. I've had it working for months on Debian Sid, but recently I updated the entire OS to get KDE 4.4 (I also went from a 2.6.30 to a 2.6.32 kernel). Something in that upgrade caused wireless to cease to work properly. The problem is similar to the one described in this thread, but no resolution is mentioned there: viewtopic.php?f=5&t=50892 I've gone through all the steps to install the STA drivers/wl module for it, and it basically appears to be working. Using wicd, I can see all the wireless networks in the area.
The problem occurs when trying to connect. When I try to connect to my WPA wireless network, it eventually fails claiming a bad password. When I turned the wireless network into an unsecured network, it eventually fails claiming it's unable to get an IP. I've also tried at the command line with wpa_supplicant and it initially appears to work but in fact it hasn't. I've also got Kubuntu 10.04 installed on this machine, and it can connect without issue (using the proprietary driver that Ubuntu's hardware driver manager allows one to use).Does anyone know what has caused this? I even tried the earlier kernel, so that's not it.

I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.

Just updated to 11.04 Natty Narwhal on my Dell Inspiron 1501 this morning and I bumped into a problem. The DSL connection I used to connect to before the update doesn't work anymore. When I was running 10.10 I had this DSL connection set up via Network Manager (right-click on the network notification area=>edit connection=>add new, using PPPoE method and user name and pass from the ISP). Now I still get the AutoEth1 connection that is created (automatically), but when I try to connect to the DSL connection, it just doesn't connect. I tried deleting the connection and creating a new one, then rebooting, but still cannot connect. Another problem is that first time I ran 11.04, after beeing prompted to reboot at the end of the upgrade, I had my wireless on and while I was trying to get the DSL connection to work I switched it off (Fn+F2). Now if I try to turn it on again, it won't start. The network manager applet is looking also different now, wheter I left-click or right-click on it is the same (used to be different in previous releases), and this makes me even more confused.
I know I probably shouldn't have rushed into upgrading without getting aquainted with the changes and the possible issues, but to be honest I wouldn't want to downgrade now to 10.10 (unity looks kind of interesting and I am looking forward to see it improved in the future) and I really need to fix this DSL connection problem on my laptop (using my desktop now)

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

Today installed Ubuntu 10.04. The problem is that I cannot connect to the internet, which was no problem with the previous version (9.10). I use WiFi for my internet connection. My network is shown in Ubuntu. However Ubuntu cannot connect to my network. After some time trying it says : wireless network disconnected

My old PC has new life thanks to Ubuntu 9.1. However, a few small problems still remain:
1. D-Link wireless adapter: My wireless connection percentage never seems to get higher than 70%, even though the wireless router is right outside the door. And to top it off, I can see other neighbor's networks and the signal strength is higher! I am running ndiswrapper if that helps, and the connection is WPA/WPA2, speed of 130 Mb/s which is great, but can I improve the signal?
2. If I leave the computer on and come back after a while, the monitor is black, and I can see that the wireless connection is still going, but I can't seem to "wake up" the computer. I have messed with the settings, but have not attempted anything in the terminal. Can someone provide a simple fix? I would like to Suspend or Hibernate, but they don't work (meaning, I can wake up the computer). So I have resorted to simply logging off each time, which works.
3. Watching streaming video using RealPlayer, many times the screen freezes, and I am unable to navigate to anywhere else on the computer. Meaning, the mouse moves, but cannot open, close, change, do anything on the computer. Ctrl-Alt-Dlt doesn't even work to pop up anything. Is there a less abrupt way to Force Quit than holding down the power button on my computer and restarting the whole thing? I am sure that is not too good for the computer.

I had no problems using my dell mini with ubuntu wireless UNTIL i did a direct connect into my home network to download some updates. Now the wireless connection option has disappeared and only shows a wired connection in "network". Does anyone know how to get it changed back. Terminal no longer shows an eth1 but lists eth0 as the wired connection on ifconfig.

Hi - I am new to Linux and Ubuntu so I have no idea how to fix or problem solve unfortunately I installed Ubuntu 9.10 from scratch recently on this laptop and all was good. I connected to my WIFI network no problem. It's WPA PSK encrypted, DHCP enabled. I just set it up in Network Manager and it was all fine. Then after a few days I installed a printer and some packages and updates via synaptics. The network connection started dropping after 20 mins or so. Only a reboot would restore it - auto connects at first, runs fine till it drops then never will reconnect. I posted on here, someone gave me some lines to put in a config file. I tried that. I didn't seem to help much, problem remained. Yesterday I checked for updates and there were a whole bunch so I just installed them all. Now I cannot connect at all. I have deleted and recreated the connection in Network Manager but it doesn't help. It tries to establish a connection but never achieves it. I am connecting to the internet now on the same laptop booted into Windows, so all the hardware is fine.
Can anyone who knows about ubuntu networking help? Do I need to do a complete reinstall? Seems a bit much, but it worked when I initially installed the OS. I want to like Ubuntu, but something as basic as connecting to the internet is pretty vital so reluctantly having to start using Windows again...

I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential
cd ~/Desktop
sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz
That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on:
cd rtl8192se_linux_2.6.0100.1012.2009_64bit
[Code]...
this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.

Since I've updated from 9.10 to 10.04, I'm having some difficulties to use the internet. Even though I can connect to my home wireless network, the connection is really slow. I've got a Dell Inspiron 1545, and here comes the configuration:
Code:
sussa@sussa-laptop:~$ sudo lshw -C network
[sudo] password for sussa:
*-network
description: Wireless interface
product: Wireless WiFi Link 5100
vendor: Intel Corporation
physical id: 0 .....
Apart from that, I must say that Ubuntu 10.04 is fantastic. Easy to use, elegantly designed and working perfectly on my PC
