View 1 Replies View RelatedI am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them). I googled quite a bit and talked to a human about this but could not fix it. We tried dhclient ra0, which returned

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.
I just downloaded and installed ubuntu netbook 10.4 on my samsung n130 netbook...love it, except for one little thing: it won't detect any wireless networks. this is how i connect to the internet at home so using an ethernet cable is not an option.i tried putting in "ifconfig wlan0 up" in the terminal, but all it gives me is "permission denied".

With this card I am not able to detect any wireless networks and after googling around I found out other people have had similar issues. But my problem is kind of unique in the sense that I'm using Backtrack as my Linux distribution (I'm not a blackhat or anything, more of an enthusiast with no malicious intentions) Also I'm not a God at Linux so if you have any solutions please be verbose! I tried the following: [URL] But the Makefile spits out a syntax error. (Makefile:29: *** missing separator. Stop.)

I installed fedora 12 for the first time last night, and I have been having a lot of trouble with my wireless. It is a Dell 1395 WLAN mini. I followed the instructions from [UR], but I still can't see any networks. Moreover, when I boot into windows I can no longer detect any wireless networks.
View 6 Replies View RelatedI have just downloaded Ubuntu 10.04 Desktop version and browsed the trial version without installing it onto my laptop. OK, I love it. I have decided to get rid of Windows 7 and install Ubuntu as the sole OS. However, I have got three questions before I do it.
1) Ubuntu couldn't detect any wireless networks. Was that because I run only the trial version? I am really concerned about it as I am a frequent Internet visitor.
2) Ubuntu preloaded movie and audio players couldn't play anything from my external HD. I got warning that plugin MPEG-2 System Stream demuxer was missing and couldn't be found (as I couldn't access Internet, I guess).
I suppose I will be able to download the missing plugins. This leads to question
3) Once I download the necessary missing plugins, what am I supposed to do with them? How to install them?
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
I've read through the stickied thread about troubleshooting my wireless and I've made it to step IV 'Making a connection.'I installed the firmware that my BCM4306 required, then tried 'sudo usr/sbin/iwlist scan'

Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB
I have had ubuntu about a month now and everything has worked great up until now, I was surfing the web and all the sudden I lost connection. I tried to connect to the signal but got nothing so I did a reboot. After the reboot my wireless signal didn't show up. i right clicked the connection icon on the top taskbar and the enable wireless is blacked out to where i cant click it.
View 7 Replies View RelatedJust recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.
However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

I'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.
Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.
It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.
Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.
I'm using a different computer to post this thread, so I'm manually writing the output.

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

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 HP Mini 5105 SSD netbook, runing Ubuntu 10.10 with 2Gb RAM. My wireless card is a Broadcom BCM43224 802.11a/b/g/n. Its driver is enabled and running. The wired network connection runs fine too. The problem: Wireless stopped working. When I right click on the network icon, the enable network option is clicked, but the "enable wireless" option is listed in dark grey and cannot be clicked on. I have recently updated my kernel version to 2.6.35-24-generic. What I have already tried: this one too I got to know there seems to be a problem with the 2.6.35-24-generic kernel. I have gone into the GRUB menu (it took some time to find out that you have to keep the Shift key pressed during startup for the GRUB menu to show), chosen the older kernel version (2.6.35-23-generic) and then removed the faulty one. Nevertheless, nothing has changed. I still cannot enable the wireless. The outcome to lshw -C network is:

I'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.
View 3 Replies View RelatedI go to the icon and it says "wireless is disabled by hardware switch", well I didn't press any hardware switch. My laptop is a Dell L501X, the "hardware switch" is the Fn button and F2. I've tried pressing this but nothing happens.
Is this a bug with the latest linux version? Cos everything was working fine until my laptop updated.
The version I have now is "Linux 2.6.38-10-generic"
I'm running 11.04 64bit.
Here is some info from console :

I am having problem with wireless networking my fedora 12 since i opened network manager yesterday. But to my notice i haven't done any changes. But still i am not able find any reason for the wireless network not to work. When i try to restart the network servies it gives the following msg.

Did i do something wrong with the network manager or did something go wrong with fedora.
Today my wireless has stopped working. I have a laptop hp6720s with network controller: Intel corporation PRO/Wireless 3945 ABG [Golan] Network connection (rev 02), dual boot vista/ubuntu 9.10, fully updated (kernel 2.6.31-17). I use a router edimax BR-6204 wg to use the net with other laptop. Till now i have using wicd for controll wireless without any problem, internet was quick and responsive. (Quick connection without any failure).
But today the internet was very slow and wireless starts to connect and disconnects intermitently, doing it unusable. This was what occured when i upgraded from jaunty to karmic and used the network manager from gnome, but then i fix the problem installing wicd. Now wicd behaves in the same way as gnome-network-manager. If i connect directly the computer to the router by wire, i have internet and everything works perfectly. How i can fix the wireless?. How i can do it works with ubuntu 9.10 and?.
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??).

Like many others it seems, my wireless has stopped working since a recent upgrade The answer does not lie in analysis of logs, settings etc. but surely with those who did it - they should provide a fix. I cannot believe everyone expects each individual users to go into their own analysis of why this is no longer working as it is clearly widespread. I have been using Ubuntu for 18 months without this problem on the same dual-boot laptop, and it still works on Windows as before, only Ubuntu 10.4 has recently stopped my network card from working.
I need to know when this will be fixed. I have been embarrassed by promoting Ubuntu to many colleagues who now also cannot work at home on their wireless networks. Seriously disillusioned I may start looking for a more stable alternative to Windows.
I have an EEE 1000 that successfully connected to WPA networks until yesterday. I tried re-installing the RT2860 drivers that had been previously modified and did not have success.
Additionally, I just installed 10.04 on a Gateway laptop that's a few years old. It immediately connected to the WPA network and I ran the updater. Lo and behold, after updating it no longer connects to the network.
I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...
I recently installed 10.04 and everything Just Worked.Before Lucid, I was using 9.04 and had successfully gotten my Broadcom 4306 working perfectly... which is why I think the Lucid install went so perfectly.Well, after a botched hiberation (Dell Inspiron 9100), my wireless is dead in the water.I've tried "ifdown", "iwconfig", "/etc/init.d/network restart" and "force-reload", 'modprobe -r b43'
View 1 Replies View RelatedI'm using Maverick and since yesterday, my wireless hasn't been working. It was working before with Maverick and I don't recall doing any updates that might have changed wireless configurations.
By "doesn't work" I mean it doesn't recognizes any networks, as if the wireless was turned off (there's this button on laptops, but it's turned on). I had that problem some time ago, but rebooting solved the problem, which, now, didn't.
My laptop is a HP dv6420la.
Where to start?
