Ubuntu Networking :: Wireless Connection Aspire 1640Z - Not Working
Apr 8, 2011
I have a new installation of Ubuntu 10.10 on my Aspire 1640Z, and since I have it, it's impossible to connect it to the web. I have a wireless connection on a SFR Neufbox (I'm french and it's a french box I guess). I've tried to be connected with a Sagem key. I have another computer with Windows XP, which is connected wireless with the same kind of key. When I use Network Manager, there isn't any automatic connection : "no network connection" and when I click on the logo of Network Manager, I can't click neither on "<<filaire>> network" nor "wireless network".
I also used Wifi-Radar, but there isn't any connection again. I created a new network on it, with the SSIF, code WPA, MAC.. But there's no connection and when I try "connect" it writes "could not get IP adress" (even if I'm in DHCP). I went to Syst�me > Administration > Network Tools > P�riph�riques > Interface ethernet (eth1) > Configurer > Wireless and I've writen the WPA, SSIF etc. again of my box, without any result. Here is what I have in the terminal with

I have an Acer Aspire One ZG5. 160GB HD, 1GB RAM model. I've done a fresh install and an upgrade of 10.04 and have the same problem both ways. I am able to connect to my wireless connection but it is dropped after about 5 minutes and have to wait about the same time to reconnect. I've had to roll back to 9.10 being that I use the netbook for work and school on a daily basis.

This bug has been around for years now?!? Surely this can be fixed by now, would somebody please feel this very common issue. I've installed Ubuntu 11.04 on my Acer Aspire One 110AB netbook and everything seems to work fine except the wireless - I can connect via ethernet no problem.
While the wireless can scan for networks - it seems them but they seem to be rather weak signals and also no matter never connect UNLESS I turn off ALL WEP/WPA security clearly not an option.

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

I had UBR installed and working fine for a month or so, wireless and everything. Then I did a clean re-install while trying to add WinXP to half of my drive.Anyway, with the new install, my wireless chip (BCM4312 802.11b/g) isn't switching on at all. I've tried installing the Broadcom driver that appears when I run Hardware Drivers, but that doesn't help.With the old install, the wireless switch and indicator light on the front of the netbook worked, now nothing.
Output from lshw -C network is:
*-network

product: BCM4312 802.11b/g
vendor: Broadcom Corporation

So I decided to wipe out Windows and try Slitaz. It's an awesome well featured distro for it's size. One huge problem tho: I can't get wireless to work for the life of me. I actually went as far as to manually load the ath5k module but It just refuses to recognize my wireless router, much less any nearby routers. It simply doesn't see anything when it scans for wireless networks. I have no problem with that in Puppy Lucid. But I'd really like to use Slitaz, just for it's small size and quick bootup. Can anyone PLEASE help me with that?
PS: It happened here before that I had to plea and beg for any response, so PLEASE(!!) don't let me hang like that this time.

lo no wireless extensions.
eth0 no wireless extensions.

Recently installed Ubuntu 10.04 on HP Pavillion ze5400.Wireless card is bcm94306MP. Wireless connection shows as disconnected. I am troubleshooting using the Ubuntu documentation on solving wifi problems. Ran ishw and it appears I do not have a driver properly installed. Obtained what I believe is the driver: bcmwl5.inf and bcmwl5.sys. Installed bcmwl5.inf using ndisgtk. I know its there as I can see it in System>admin>windows wireless drivers. However lshw still does not show it under configuration. I understand I must put the sys file in the same folder as where this inf file got installed. I assume all I do is copy and paste it into that folder. Is this correct? Next I need to find that folder. I tried the command find /home -name bcmwl5.inf and it did not show up. Can someone educate me just how to do this, that is find the folder and insert the sys file?
After I pass this hurdle then I will tackle trying to configure the card.

in compliance with bonekracker's advice, i have reposted my SOS. i have the result of the outputs of the commands for ifconfig, iwconfig, and etc i have uploaded it in the file output.doc. i hope this would be helpful in debugging my problem.but before that, i do notice that if i click on the icon for the Network Manager, the Wireless networks is set to 'wireless disabled'. maybe if i can make it turn on, my wireless problem will be solved.. its just that i even if i move the switch for the wifi, it still wouldn't turn on.

I have a cisco linksys wireless adapter (WUSB600n) which, most of the time, great when booting up. But mostly after some time (1min- 1hr.) it disconnects. When checking the status I can see some of the networks around me, including mine. But selecting it doesn't do anything. I searched the forums and tried:
sudo dhclient
and
sudo /etc/init.d/networking restart
But still no connection; the only thing that helps is rebooting.

I am using Ubuntu 10.04 LTS - Lucid Lynx(great interface!). But I am experiencing a very weird problem. The wireless internet works just fine at my apartment. But when I am in my school, it just stops working at all. It didn't use to be like that. It used to work in school too few weeks before. But I don't know what happened all of a sudden. I have checked with my school system administrator to know if there has been any change with the network. He said the network has always been the same.

I'm using a WUSB54GC network adapter to connect to my home wireless network. My network was not visible, so I added it and it shows connected, but when I launch the browser, I can't get a connection. I'm using Ubuntu 10.4. All other computers on the network connect fine and I disabled my firewall to see if that made a difference.

About a week ago I upgraded to Maverick from Lucid.
All networking worked fine on Lucid.
I am using an Acer Laptop with the Atheros AR928X Wireless Network Adapter.
I can connect to my home network (visible, with WPA2-Personal) fine. However, I cannot connect to my university's wireless network. The only difference I noticed is that its network is using WPA2 Entreprise with Tunneled TLS Authentication and MSCHAPv2.
I tried dmesg and I got:
wlan0: authenticate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: authenticated
wlan0: associate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: RX AssocResp frin 00:1a:1e:ef:f4:e1 (capab=0x431 status=0 aid=2)
[Code].....
Unless the driver has changed, I suspect this is not a driver issue, since it worked fine on Lucid. Is this a NetworkManager issue?

I have a laptop Acer aspire 5100. I installed Ubuntu a while ago and it was working well. Last week I updated it using Update manager and ever since I haven't been able to connect either wireless or wired connection.
I get this:
Code:
The wireless card seems to have disappeared.
I reinstalled Ubuntu and the problem persists.

I just finished upgrading from 9.10 to 10.04 via the Update Manager. My first noticeable problem is that my wireless connection with my home network no longer functions on my IBM Thinkpad T42 laptop.The Network Manager applet shows that it detects my home network (and those of several of my neighbors), but I have not been able to get it to connect to this network. I've been using WPA & WPA2 Personal settings for security, and the Network Manager applet had correctly picked up the password that I had been using under 9.10. I've searched the Ubuntu Forums for "wireless T42" and thought I'd found a solution in a posting that recommended using the "wcid" network manager, but I've been unable to find wcid either via the Synaptic Package Manager or the Ubuntu Software Center.
1. I've noticed that in Lucid Lynx the Network Manager applet's icon in the top panel is no longer the vertical bars symbol that it displayed in
Karmic Koala; instead, the icon is a radiating fan display. In the Network Manager's edit Network Connections window, this fan icon is shown on the Wireless Connection tab, while the vertical bars icon is shown on the Mobile Broadband tab.
2. The Wireless Connection tab shows, on the line in which it shows awareness of my home wireless network (as "Auto 389690") that this connection was "Last Used" "1 month ago". It should be saying something like "today".
FWIW, the Network Manager detected my wired "eth0" connection with no difficulty.Both Jaunty and Karmic picked up my home wireless connection without any problems. Now I have no idea what to try next.

I have just installed Maverick meekat on my new laptop with Wubi, and I have been trying to setup my wireless connection, but i couldnt. The first thing I tried was going to System>Prefrences>network connections, and clicking on the wireless tab. I tried to add a network think manyally, and I miserably failed.
here is the information I have of my laptop as of now after doing the lspci command in the terminal:
Network controller: Brodcom Corporation Device 4727
USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller Ethernet controller: Realtek Semiconductor Co., Ltd.
Also I have read somethings about ndis or using the windows driver and things of that sort. Whenever I am using windows, my wireless connection is working perfectly. So I dont know if there is a specific way to activate my drivers, or if my computer is just not capable of having wireless connection on Ubuntu.

I have a problem with my wireless connection in ubuntu (natty with amd64bit) There seems to be intermittent disruption in my connection. Havent seen a pattern as yet, though it happens once a day. After that I cant get it to work at all and only restarting + reconnecting the USB device helps. Dont know what is going on.I have already read these pages : Commands and Wireless Troubleshooting.Here is my line of though1) Given that I am able to connect other devices to it while I am not able to connect through this desktop, I think the router is OK.2) I am able to work with it after restart + re-connection . And so the driver is OK and is loaded. The driver seems to be oK and loaded even while I am not able to connect.So why is this happening and how can I get this under control without having to reboot and re-connect the device everytime.Here are the output for the commands which will give you a more detailed idea of the process. Before reboot while I was not able to connect:

I have a very strange problem with Fedora 12 and my wireless Broadcom 4311 card.After the installation of Fedora 12 the wireless card was visible but not activated. I did an extensive search in Internet and finally I got everything done. The card was visible and activated. I found my home network; the strength of the signal was nearly 100%.The problem is that although the card is visible and activated my browser is not working well. I can say that it is not working at all. Even now I am using other computer to write this message because Firefox cannot load any web page at all.
The strange part of the problem comes with the fact that when I open terminal window and when I am using yum everything looks OK. The speed is very low though.Does anybody have some ideas about the problem and its solution?When I use Windows on the very same computer everything is fine, the Internet speed is close to the maximum limits of my provider's speed which is 10 mbps.

I have a dual boot (XP Pro and F13) laptop. This laptop has a Ralink RT2501USB Wireless Adapter which works perfectly fine on XP. But when it comes to F13, adapter only works properly when I am physically next to my router. When I move few feet away the strength of the connection drops from 100% to around 40%. But even though 40% should be okay for slow connection to internet, I can't get any internet access at all. I have tried three different routers with same results on each.
When I boot same machine with windows XP, all works fine. I can move to any part of my house and I will still have the connection without any issues.I can see that RT73 driver is installed if I check in add remove program under system.I am not an expert but to me its seems that the drivers on F13 for RT2501USB are not as good as on windows?

I'm using Archlinux with NetworkManager to connect to the internet. When I'm in my room, I've an ethernet cable and still receive the wireless signal.Sometimes (like when we have a power cut, somebody is rebooting the router or simply something wrong with the provider), I'm disconnected during a few seconds, NetworkManager ask me again the password of the wireless (even if it remembers it), and then I'm ok.But when I'm not in front of my computer, while I haven't push the button "ok", it doesn't connect, even with the wired connection.That's not very normal in my opinion as there is supposed to have two different and independent connection. No ?
I intent to install an ssh server on my computer but if I cannot access it every time there is a problem that won't be very useful.

I have ubuntu 9.10 and my wireless connection has been working perfectly until a few weeks ago when I updated my laptop. I can connect to the internet using my wired cable but not by wireless. There is nothing listed under my wireless list. I am new to this and have been unsuccessful in getting my wireless connection going again. I don't even know were to begin. I have a 2wire modem also.

I've been using a RealTek 8190 PCI wireless card on my desktop in Ubuntu 10.04. The net819xp driver worked fine in ndiswrapper. Then my housemates got a new router and switched our wireless SSID & password. In network manager, I can see the SSIDs, but when I try to connect to our SSID, it continues trying to connect but never does connect. Something related to the router change and router firmware upgrade created this problem and i'm sure i need to fix it on my computer. All my windows7 flatmates are connecting with no problem. Right now I'm using my laptop, so i can't copy & paste results from terminal commands,

I recently installed ubuntu in my laptop using a usb stick. everything seems to be working fine except the wireless connection. the notification area doesnt show wireless network at all. i tried browsing many forums n folled the steps suggested but in vain. with the command
sudo lshw -C network i get result as:
unclaimed
so, i tried using windows wireless driver (its Broadcom). i cannot install the ndisgkt package from the package manager. The package is shown but when i try to install, the package manager shows 'In Progress' and nothing happens. Hence, System → Administration → Windows Wireless Drivers is not displayed at all.
If a driver can be downloaded n installed, how to do that. I would download the wireless driver from my windows OS n install in ubuntu.

I buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.
Notes:
- I have another PCI Wireless adapter which works fine.
- The problematic adapter works great on windows.
- A driver CD came with it, including a linux driver which I wasn't succesfully installed.
- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.
It took me dozens of surfing the web hours, and too many restarts,

I'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.
I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.
