Ubuntu :: 10.04 - Could Not Detect Wireless Networks And Missing Plugins
Jul 23, 2010
I 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?

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.

I 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
There is already a pid file /var/run/dhclient.pid with pid 2438
killed old client process, removed PID file

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.

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".

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'

Right so I just bought an Acer TimelineX with a Broadcom BCM43225 BCM43225 802.11b/g/n WiFi card. 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 have a broadcom 4322 with the broadcom-wl driver on Fedora 11. It worked the first time I used it, and since then is unable to detect any networks. I've tried reinstalling the driver, and it still does not work. Any suggestions?

There was quite a bit of threads about this card, and getting it to work mostly boils down to downloading Ralink's propitiatory driver. The card uses RT2870 chipset, and Ubuntu comes with two drivers that are supposed to support it, neither of which seems to work with WUSB600N. One of the drivers included with Ubuntu detects networks operating on 2.4GHz but fails to connect to them, but does not detect 5GHz networks at all.
I was wondering if anybody knows what is so special with this card that it doesn't work with drivers that are shipped with Ubuntu? The card works nicely with Ralink's driver, but it's a bit annoying to have to recompile it on every kernel update (would be much nicer if it worked with stock drivers).

I was listening to music one day, and I decided that I wanted to watch a video on my laptop, so I put in the DVD, click play, and suddenly I'm missing the Windows Media Player 8 decoder. I try some of my other videos (of different formats, including .FLV and .AVI), and they're all missing different decoders. Also after that, and ONLY after that, RhythmBox can't find the decoder for .WMA files, yet it still plays .mp3, .ogg, .flac etc. I snooped around and downloaded various gstreamer plugins, and when that didn't work, I tried reinstalling all of them. Still no luck.
In short, I think part of my decoder and plugins folder got corrupted or deleted. VLC will play everything still. This is something I find bizarre.

I have been searching the internet in vain for the names of the packages that provide the following plugins for kdevelop in Debian Squeeze. The missing plugins are preventing me from testing the written programs.
Missing plugins:
1) C++ support
2) kdevcvs
3) make builder
4) output view
5) QtHelp
6) Subversion
The icons representing these plugins are all a question mark. I am assuming that means that they are missing. Needless to say, as it is, kdevelop is useless.

Code...
To find the appropriate firmware without knowing the make or brand of your wireless chip, you can use the command:
#fw-detect
But apparently debian package do not offer this useful tool, well, certainly for sidux exclusively.
Is there a package of fw-detect eventually?

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

I am using opensuse 11.2. The totem video player states that I am missing a gstreamer plugin. I checked to see that gst-ffmpeg plugins is loaded, also libdvdcss, libdvdnav, libdvdplay, and libdvdread are also loaded. I would like if someone could please tell me what gstream plugin I'm missing, and where to place it.

The gstreamer-0.10 good plugins in CentOS 5.4 seems to be missing souphttpsrc. I looked online and can only seem to find references to it being in the bad plugins, yet the bad plugins documentation says it was moved to the good plugins.My experience downloading rpms is that the dependencies to build anything for gstreamer require I also download about 20 other rpms.I am reluctant to download/install rpms for a different distro.Has anyone successfully installed newer good plugins (particularly, souphttpsrc)?

I am trying to make the sound quality better on my Ubuntu.
I have read some tips in this topic: [url]. This made to go to this topic: [url]
It says there this: (If you are lazy to click )
Re: NEED better audio quality
Quote:
I can tell you flat out that foobar with the secret rabbit plugin, even without any internal or external equalizer completely tears up linux sound.
No, it doesn't.
In Linux you can easily choose Secret Rabbit in SRC_SINC_BEST_QUALITY mode as your system-wide sample rate converter by adding a single line to either /etc/asound.conf or ~/.asoundrc (requires libasound2-plugins and libsamplerate0 to be installed):
Code:
Now show me how to do that in Windows.
I have both of those packages installed, but for some reason the file asound.conf and .asoundrc are not there so I cannot add the line.

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

I've Vaio P39 with Karmic 9.10(2.6.31.21). Everything is ok excluding the WWAN. It just is missing in available networks list to connect (LAN and WiFi are ok).
Searching gives that WWAN adapter doesn't start at cold reboot and it's proposed to use Win7 to switching WWAN on and then restart. But it looks like - must have Win7 only to switching WWAN on...This kind of solution for some Vaio laptops
Code:
Probably bad searching from my side but I've no solution yet. Does it exist at all?

I have a wireless network at home. My home laptop connects without any issue.I have a wireless network at work. My work laptop connects without any issue.If I take my work laptop home, it can see the network but cannot connect to it. I've checked the passphrase and that's fine, I've deleted the network from the Network Manager profile and re-created it - no luck.
The only thing I can think of is that I had to change the wireless router network channel at one point. I think that the work PC could access the network before that (but it was a while ago). I've tried changing the channel back, but to no avail. I have to keep the channel at its new setting anyway to avoid a loss of signal.What sort of things should I be checking/changing to get home connectivity on my work PC? The wired network is fine, but my wife draws the line at me looming over her desk with a red cable plugged into the back of my laptop.

I just got myself a Dell Inspiron 1440. And decided to install my favorite distro Debian. I got the installation to go with no issue and all seems to be working fine. However the wireless isn't working. NetworkManager doesnt even detect a wireless card. I followed the instructions here and installed the b43-fwcutter and then issued the modprobe b43 and modprobe b43legacy commands. Then I issued the iwconfig command and this was the output.

Also, I've been doing some research and found out about some file located /etc/udev/rules.d/70-persistent-net.rules. So I looked in mine and found out that only my eth0 is added.

I have configured a wireless pcmcia card using ndiswrapper. I'm sure that works, as with the command "iwlist wlan0 scan" gives me back
the list of detected wireless networks. At this point I was wondering: is there a way to detect the new interface (wlan0) with network manager? Even after enabling the wifi card the network manager gnome applet always finds only eth0.
