Ubuntu Networking :: No Wireless Connection In Lucid?

May 8, 2010

I have a Dell Studio XPS desktop too difficult to reach with cable. Instead I connect through a Dell Wireless 1500 Draft 802.11n WLAN Mini-card which works great with 64 bit Windows 7.

Installed Ubuntu 10.4 yesterday (wubi) but no wireless activity! Despite Googling extensively and reading through Ubuntu Forums I've not been able to find a solution so far.

Ubuntu Networking :: Lucid: Wireless N Taking Precedence Over Ethernet Connection?

Jul 26, 2011

I have one of these nifty Atom based "net-top" boxes that has built in wireless N and gigabit ethernet. the problem I have is that even when the ethernet cable is plugged in Ubuntu seems to be defaulting to use the wireless connection. This is a problem since in some areas of the house where I have a wired connection the wireless signal is pretty weak and so the ethernet traffic becomes spotty.

is there a setting somewhere where I can force ubuntu to prefer the wired over wireless no matter what, or to disable the wireless when the ethernet is plugged in?

Ubuntu Networking :: Wireless - Lost It - 'wmaster0 No Wireless Extensions', But Then Refers To Wlan0 As The Wireless Connection

Mar 28, 2010

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.

Networking :: Use The Laptop With The Wireless Connection To Share The Internet Connection?

Feb 4, 2010

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.

Ubuntu Networking :: Flaky Encrypted Connection With Atheros AR5001 10.04 Lucid?

Jul 31, 2011

I've been having problems with the Atheros AR5001 wireless card in my EEE PC. Whenever I'm connected to an encrypted network of any description (WPA2 at home, WPA-PSK at work), the connection will drop out after some time, ask for the key again, then will drop out after a shorter time. This repeats until it's continuously asking for the key. This is no problem with an unencrypted connection. I've installed the madwifi module as per the instructions in this thread, but that doesn't seem to have helped.Ubuntu 10.04.3 LTS, 2.6.32-33-generic i686 kernel.

lspci:

Code:

01:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

ifconfig:

Networking :: Lucid Lynx Suddenly Lost Connection ?

Mar 5, 2011

All of a sudden without rhyme or reason, My Lucid Lynx install stopped connecting to my network. This was without any intervention from me as I did not modify install or change anything prior to this happening.

What I have gathered so far is that upon initial boot eth0 seems to always be disabled. So I ifconfig eth0 up to bring it back online. All the settings in the network applet seem to be intact for my manual network that has DHCP disabled. Let me re-iterate that these settings worked fine for months then all of a sudden something went belly up. The same machine will connect fine with the same settings from within Win7.

ifconfig command shows both eth0 and the loopback interface but eth0 never manages to secure the 192.168.1.3 address that it should have. ping 192.168.1.1 returns "Network unreachable" so it appears the connection is being cut off at the machine and not the router. I did check to make sure the connection was even recognized and it sees the wired connection going to the router, but nothing else.

/etc/network/interfaces only shows two lines regarding the loopback interface and nothing else; eth0 seems non-existant within this file which I find odd.

Ubuntu Networking :: Lucid - Wireless Button Controls Bluetooth / Shows "wireless Is Disabled"?

So, after installing Lucid wireless doesn't work for me. When I click on the network icon on the status bar, it shows "wireless is disabled".

With that message, I press the wifi button on my HP laptop and it turns off my blue-tooth, without changing the status of my wifi.

I found this rfkill command in another thread:

Before doing anything, after bootup:

Code:

Fedora Networking :: Unstable Wireless Connection With Broadcom Onboard Wireless?

Dec 21, 2010

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.

Ubuntu Networking :: Eee Pc 1001HA Lucid Not Even Turning On Wireless?

May 1, 2010

i updated to lucid lynx from karmic (i could not get wireless to work on that either) with the hope that wireless might actually work but it doesn't, the keys to turn wifi on don't even work with lucid there is no way to get the wireless to even give me a light that says its on. I have tried installing the rt3090-dkms package and it installed fine (took ages) however that has done nothing at all. It is kind of pointless having a netbook without wireless so anyone got any ideas this is getting very annoying I have yet to use wifi since i bought the netbook

Ubuntu Networking :: Connecting To Wireless In Kubuntu Lucid?

May 14, 2010

I'm having trouble connecting to our home wireless network in Kubuntu Lucid. I was hoping someone here might be able to help. I can connect with no problem in Ubuntu and Xubuntu; I'm having difficulty in Kubuntu only. It might just be me being unfamiliar with the KDE network management app, I don't know.

1. I click on the network icon in the system tray, and choose "manage connections". I click on the "wireless" tab, and click "add".

2. I enter the name of our network in the SSID field (our router doesn't broadcast its SSID; however, if I click "scan" the neighbors' wireless networks do appear in the list) under the "wireless" tab, then I go the "wireless security" tab, and choose "WPA/WPA2 - personal" and enter the password. I click OK.

3. Now when I right-click on the network icon and choose "create network connection", the new connection for our network that I just made shows up in the list, but it has an icon showing a pen on paper instead of the broadcasting signal icon that appears next to the neighboring networks. It also says my connection is "insecure", even though I chose WPA and put in the password. (Neighbors' networks do say WPA, WEP,etc.)

4. I select my network connection that I created above, and click connect, and nothing happens. No connection is created. how the KDE network app works; I've used mostly XFCE and GNOME in the past, but I've heard good things about Kubuntu Lucid and really would like to take it for a spin. However, this computer has only a wireless connection, so I really need to get it working.

Ubuntu Networking :: Lucid Not Recognizing TP-Link USB Wireless

Jun 13, 2010

my card is not recognized in any way by ifconfig or iwconfig as shown below, but is visible via lsusb. It is 54Mb usb, and has a detachable antenna with the Atheros chipset shown below. I have removed (by #) the ath_pci from the blacklist under /etc/modprobe.d but cannot seem to start this still. I used compat-wireless-2010-06-01 (06-12 appeared to have errors I could not easily overcome). The lspci -nn command only shows my internal broadcom which I am not currently using. My goal is to do wireless research so I need the atheros (among others)...

my hw: Dell series n, TP-Link's TL-WN422G USB wireless stick

$ lsusb | grep Ath
Bus 001 Device 004: ID 0cf3:1006 Atheros Communications, Inc.
$ lsmod | grep ath
ath9k 71145 0

[Code]....

Seems to me that their should only be one ath9k driver, but several are loaded. Are all required for functionality perhaps?

After upgrade to Lucid I have experienced intermittent wireless disruptions.

I use the 64 bit OS, and this problem did not appear prior to the upgrade.

Ubuntu Networking :: Missing Wireless Rt3070sta Drivers In Lucid

Has anyone managed to get wireless Ralink rt3070 drivers working in Lucid? Before in Karmic, you could "sudo modprobe rt3070sta" as they were "stagging" drivers already in the kernel, but apparently they're missing from the kernel in Lucid as reported here [URL]... I get errors when compiling the latest drivers from Ralink (DPO_RT3070_LinuxSTA_V2.3.0.2_20100412) and they don't seem to work.

Ubuntu Networking :: Broadcom Wireless Stopped Working In Lucid?

May 5, 2010

after having tried out almost all suggestions found here and elsewhere on the internet, i'm somewhat at my wits end The situation: I'm running Kubuntu 32Bit Version (at the mom 10.4) on a HP-Compaq 6735s (AMD Processor, Vanilla 32Bit Install). My first Install was last year with 9.4 and the Broadcom 4322 wireless worked like a charm after installing the proprietary STA-driver under System -> Hardware Drivers. As the update didn't work out really without glitches, i did a fresh install and lost my wireless. I tried various combinations and tutorials but to no avail. My card is found, the driver installed, but i cannot access my access-point. I can SEE the access point (and all my neighbors'), but knetworkmanager does not seem to do anything. To be sure, I installed wicd (nice tool by the way). Trying a connect here told my my credentials were bad (incorrect passphrase for my WPA2 Personal auth), which is not true. I tried connecting without security, didn't get an IP. So it seems somehow the card is working, but all functions needed for passing information to the access-point are unavailable.

This is what I tried:

both broadcom-drivers
fw-cutter
installing the driver by hand

Installing the driver via Hardware Drivers produced the same results as any other, viz the card is working, but not connecting. Unfortunately knetworkmanagers error messages are a bit sparse, or rather non existant. My guess is that somehow the firmware is not properly loaded (or the wrong type??).

I need to download something that will fix it (possible update if one has been released) to xp (partition) then access xp partition from ubuntu and install it.

Ubuntu Networking :: Intermittent Wireless With Atheros AR5001X+ On Lucid?

Sep 12, 2010

I have an old Tatung tablet pc, with touchscreen, stupid speakers and an atheros wifi card (AR5001X+). With XP, everything works reasonably well, and wifi connectivity is rock solid. I know I'm asking for trouble installing *nix on this machine, but if the wireless worked, I'd be happy. However... With an updated Lucid install, I can see and connect to open, WEP, and WPA(1/2/tkip/aes/whatever) networks. I get good speeds with every network I've tried, but after a minute or two, my connection speed drops to zero, only to recover after another few minutes. A few minutes later, the wireless dies again, then reconnects....

Both the router and the tablet show that I still have a connection, and the connection speed recorded by both does not change from the 'working' condition. I get nothing in the logs (router or tablet) and no indication (aside from transfers stalling) that there's any problem. The 'network history' part of Gnome system monitor shows the data rate dropping to zero, but a network monitor applet on the gnome panel shows transmissions and (later) recieves. Reported signal strength remains constant, and seems to have no bearing on the frequency or length of the dropouts.

I've tried the stock lucid drivers, the lucid wireless backports, and madwifi (currently on madwifi) with no change to symptoms. I did think that it may be to do with scanning for networks (iwevent showed completed scans as the dropouts ended) so I removed network manager and tried static configuration with /etc/network/interfaces . The problems persited (although iwevent is now silent) and I am now using Wicd with no change.

lscpi:

Code:

sudo lspci
00:00.0 Host bridge: Intel Corporation 82852/82855 GM/GME/PM/GMV Processor to I/O Controller (rev 02)
00:00.1 System peripheral: Intel Corporation 82852/82855 GM/GME/PM/GMV Processor to I/O Controller (rev 02)

[code]....

I see nothing toobad in these, so I ran a longer test - I bash'd a while loop to ping the router, run ifconfig and iwconfig, and spit the results into files. I concurrently ran a wireshark capture. All of these contain a lot of text/data, so I've attached them here. I can't see any connection between the output of ifconfig/iwconfig/wireshark while the ping drops, but I'm no expert.

Ubuntu Networking :: Lucid Freezes With Compat Wireless Patch

Nov 23, 2010

I've got an atheros ar9287 based card with the ath9k driver from the base install of lucid and I installed a compat wireless patch via this thread: [URL]... to fix the issue of the card being stuck on a given channel when using aircrack. Now, my system freezes up after about a minute or two. If I leave the wireless card off, everything runs fine no problem. I uninstalled the compat wireless driver via the readme just make uninstall in the compat-wireless folder, but I still get the freezes. So I assume it has something to do with the patches. I have no idea how to remove the patches. Can anyone help me with this or is there a way to get everything up and running so the original problem of being stuck on a channel is fixed?

Ubuntu Networking :: Kernel 2.6.38-x And BCM4328 Wireless Card On Lucid?

Feb 23, 2011

I am having some issues getting the broadcom sta driver installed on Kernels 2.6.36 up through 2.6.38.

Before I continue, I'll list my specs
Release: Xubuntu 10.04.2 LTS (64-Bit)
Wireless Card: Broadcom BCM4328
Kernel: 2.6.38-x (Any version), and 2.6.36 and above

EDIT: Yes! Yes! I got it to work, for those that are having issues, install this packages. Disregard that it says that there is an older version available in a software. The bcmwl-kernel-source for Natty works on Lucid![URL]... Install one of these and check your Hardware Drivers, they will probably say that the Broadcom STA driver is installed but not in use. If you then proceed to restart it should be up and running, this way you can use kernels 2.6.36+ and still use the Broadcom STA driver!

Ubuntu Networking :: Lucid Wireless Disconnects For No Reason And Can't Find Password

So I installed Lucid again from scratch and now everything seems to work fine. The only thing I didn't do was install the 'restricted drivers'. This was only one driver for me which had to do with my modem. Wifi works perfectly now. I hope it stays that way .reinstall Lucid and DO NOT install the 'restricted drivers' for your modem

I am having a problem setting up my wireless on Ubuntu 10.04 (Lucid Lynx) on my desktop computer using a Linksys Wireless-G Portable USB Adapter WUSB54GP.

The wireless has run fine on my Thinkpad X60s laptop running Lucid and with my desktop and the same USB adapter in Karmic (9.10). When I installed Lucid as an upgrade on the desktop, I could not see the adapter listed at all and could not connect wirelessly to the internet.

if I need to install drivers, edit a file, or do something else to get this working I couldn't find anything useful to actually solve my problem after searching for a while.

This should be all the important desktop system specs: Linksys Wireless-G Portable USB Adapter WUSB54GP -- not found; can't connect to wireless internet
Lucid Lynx 10.04 (straight install from CD from Canonical)
