Ubuntu Networking :: Wireless Networks No Longer Detected
Jan 29, 2011
I have a msi netbook with ubuntu netbook remix installed and it was working great until yesterday when suddenly it stopped detecting my home network. There are no problems on my two other machines, so I'm sure the problem is the netbook. I have no idea how to go about troubleshooting this. I was hoping someone could help me by giving me a place to start.
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:
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 have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.
I'm dual-booting Ubuntu 9.10 (upgraded from 9.04) and Windows 7 on my Dell Inspiron 1525 laptop.Ubuntu doesn't recognize any wireless network (both in 9.04 and 9.10); my Windows OS works perfectly well with wireless, as does my wired Internet connection with Ubuntu and Windows.I've had this problem on previous installations of Ubuntu (I've removed and re-installed it several times) but I can't locate the solution anywhere. I've tried numerous fixes that I've found online, but none of them have worked.System>Administration>Hardware Drivers tells me that the Broadcom STA Wireless driver is activated and currently in use
I've tried every fix i could find. I'm on a Dell Inspiron 1420 running Ubuntu 10.10 lucid lynx using a BCM4312 LP-PHYi've tried everything to get my wireless networks to connect but nothing works. I finally got my computer to recognize my wireless card but it doesn't detect or connect to networks. Before i was able to at least see the networks but not connect or stay connected once i disconnected the ethernet cable. i will post the output of ifconfig, iwconfig, iwlist scan
I've used this computer to connect to a wireless router before. I recently moved and for some reason it isn't working.I have a too long of an lspci output to type (I'm on a different computer).
I have ubuntu 11.04 installed. I have a D-link USB Wireless Adapter. Ubuntu detected it and it worked fine. I have a Beetel 450TC1 Router which broadcasts my internet connection. Ubuntu recognizes it, and keeps on trying to connect.It asks me for Authentication again and again.( Don't tell me to check the password again, it does work on everything else )And its not the router problem also, as I tried broadcasting through a laptop I have, Ubuntu again detected but couldn't connect and kept asking me for Authentication
New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.
I'm running ubuntu 9.10 on my desktop.Wireless networks appear on the dropdown menu but when I try to connect to my home network the authentication box appears, after typing my password the box disappears and it continues to connect but nothing happens and after a while the authentication box appears again. So.. no internetz connected.
I am running debian testing dist-upgraded to sid with the latest gnome-shell. All is fine, I have recently moved to a new house and noticed that network manager wont detect my home wireless network. It does scan for networks and locates SSIDS from other local networks including my neighbours wifi where I can connect but will not detect mine. The modem router used is a zte quite popular in Greece and I have the broadcom wl driver installed. By the way since it is a dual boot machine - nasty win7 connect just fine and so does my mobile phone...
My wireless network is being detected but it refuses to connect to it. I am entering the accurate passcode and I have tried doing various commands for it to work, but it is being stubborn.
Also, it would help to know which WEP Index to use and type of Authentication.
I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.
I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue.
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.
I installed ubuntu and i installed it using the install as a program inside windows options but when I boot into ubuntu it does not detect any networks I tried the command sudo pppoeconf it says ethernet card is not there and then it asked me to try modconf and when i try modconf it says that modconf is not installed How can i set internet connection in ubuntu 10.04 I get address assigned by DHCP
No wireless after upgrading to linux kernel 3.0 in opensuse 11.4. I'm using Kde and gnome 3, everything was working fine under the 2.6.39 kernel, but now both only detects my wired connection. Any help resolving this would be greatly appreciated. I have a Netgear WNDA3100 adapter that uses the Atheros drivers. It also is no longer detected in my Fedora 15 after upgrading the kernel, but it still works in Mint 11 with the 2.6.38.8 kernel.
I have a Realtek gigabit onboard ethernet (RTL-8110SC/8169SC)It was working in 9.10.After upgrading to 10.04, the connection dropped to 10MB. Now, lspci -v shows the card, but Ubuntu no longer recognizes eth0!I have no connection on the machine. I've been digging around the forums, but can't seem to find what I need.
I have an absolutely bizarre hardware issue (concerning the Atheros AR8132 PCI-E Fast Ethernet Controller) that has been giving me quite a bit of grief for a while, and having completely hit a wall on this one, I'm a reasonably-experienced Linux user of several years, and have been running Ubuntu 9.10 on an Acer AOD250 netbook for several months out. I know that this model has wireless issues out-of-the-box (easily fixed), but it did not have any noticeable ethernet issues. That is, until I attempted an installation of Arch Linux.
During the Arch Linux installation, the ethernet card was initially detected, but unable to be used (because of a bad module in the kernel released with the installer). As I didn't know the fix for this at the time, I decided to reinstall Ubuntu 9.10. This time, however, the system failed to recognize the wired ethernet whatsoever. Instead, the external activity lights for the port (green and orange) are ALWAYS on, yet the device doesn't function.
I have done a successful install of the latest drivers directly from Atheros for the device and have them automatically loading with the kernel during boot, but as the device isn't recognized, the drivers aren't doing any good. Relevant information:
I have a ZTE HSUPA USB Modem Model:MF636 which used to work great and then is not longer detected.
I am using Fedora 12 and was having problems with the modem not been properly detected and filed a bug, which turned not to be a problem of NetworkManager, but an issue with udev. https://bugzilla.gnome.org/show_bug.cgi?id=603433
I followed instructions to edit /lib/udev/rules.d/61-option-modem-modeswitch.rules and then it worked fine.
Now the modem is again not properly detected. Here is a copy of the results from dmesg code...
I have tried restoring the file that I edited. It was back to the stated previusly reported. I also have tried to run an older kernel. Then I updated to the latest kernel available for Fedora 12. Nothing seems to work.
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 am using Ubuntu 10.04. The Tata Photon+ card Huwai EC1260 was working flawlessly. However, I recently did a firmware upgrade on the card that was provided by Tata Indicom for it to work on Windows 7.
After that, the card is no longer detected as a mobile modem in Ubuntu. If I try to add a new connection, all options are disabled (whereas earlier Tata Photon card would appear automatically).
The product ID has changed. What change can I make to Ubuntu to enable it to detect the card again.
The problem with my wireless network. I have Dell DV6 Pavilion 2115 eg laptop and i installed Ubuntu 11.4 and internet and wireless worked, until i reboted my system it has disapear. I cant no longer to connect to a wireless network. It dont shows me any wireless network. My wireless card is Atheros AR 9285 802.11b/g/n Wifi Adapter
I am using a Toshiba Laptop model P205D-S7802 with an atheros wireless card. Since I upgraded to 10.04 I am unable to connect to the internet unless I use an ethernet cable. I have been surfing the threads for a fix and have tried what has been posted but to no avail.

I'm running Ubuntu 10.04 64bit on a Thinkpad T61, and I keep running into some issues with the wireless networks. For a while, the connection works fine (sometimes several hours, sometimes 15 minutes or so--there doesn't appear to be an event associated with it). Eventually, though, the connection disappears; first, though the widgets say I'm connected, nothing will go through, and soon after, it realizes I'm not connected and, moreover, it can't find a single wireless network, despite the fact that it was just fine a couple of minutes beforehand (and other devices still have access to the WLAN, so I know that the router hasn't crapped out). I've tried using wicd, but the same thing happens.
I am quite new to Ubuntu, so please give me easy to follow steps.So, I have just installed Ubuntu 10.10 x64, but cant get my wireless to work. It detects my networks and tries to connect to them - infinitely, whithout success.I have tried it on an unprotected and on a WPA2-personal protected network with the same results.My card is a RaLink rt3090.
I have a pretty beat-up laptop, on which the inbuilt wireless doesn't work, and so I now have an ASUS WL-167g, which is acting up!It almost always connects to the required networks without an issue, but then once I'm connected it's REALLY slow on some of them! For example, while I'm at school, it works flawlessly! And at a couple of friends' houses, it works too! however, at home, and at a couple of other places, despite the fact that it connects, its so slow, that google takes like 5 mins to load and searching for anything on google leads it to time out!! This happens whether I'm right next to the router (full signal strength) or 2 floors up (at like 3 bars strength)!
It's getting pretty frustrating to have to swap my lan cable between my desktop and laptop constantly, and also to not be able to use my laptop away from my desk!Does anyone know what might be going on??Also, while i have you guys here! I have another problem -- with the inbuilt card.. Initially, it wouldn't work at all.. but more recently, it has started to function (it connects and works on my home network fine) the only problem is that about 10 mins after I turn the wireless switch on on my laptop, it hangs! (EVERYTIME) (if it's relevant, my laptop is a SONY VAIO VGN-S46GP). Again, any input would be appreciated!!
