General :: Will Not Find Wireless Networks?
Nov 17, 2010
I have an HP Netbook that has Linux MintI have absolutely no issues with awired connection, however my internal wireless will not search and find wireless networ in range. It appears I have one saved (my home network) and I can connect to that, however, if I take my laptop to school or work, it will not find any networks to connect to. On a side note, I have no icon on the taskbar indicating wireless, and I used to have one. I have no idea where it went or what happened. I can answer most questions you may have but im a relatively new linux user (but I have a coworker that "knows all" and could help answer a question that I cannot.

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 have a MSI A6000 laptop (the laptop that won't accept 10.10 because of the nvidia card) so finally I opted to get Ubuntu 9.10. I successfully installed with a dual boot.
There are two problems though that I have ran into.
1. Ubuntu 9.10 is not picking up wireless networks.
2. The Ubuntu graphics (icons, taskbar and windows) are much to large. I am guessing this has to do with the Nvidia card (nvidia GeForce 8200m G).

well traded my desktop for it and its a Dell Inspiron 1721. The Wireless was working fin when it had Windows vista on it but when I installed Ubuntu 9.10 The wireless just seemed to not exist. The LED wouldnt even turn on. So I installed wicd and then the wireless icon began working but it still won't find any wireless networks.

I like to do a lot of my tasks through the command line, and was wondering, is there a way to see all the wireless networks available in the terminal? I tried 'iwlist scan', and it said all the interfaces do not support scanning. Is there anything I can do?

I am using 11.3 (64-bit gnome) and have a new Tenda w322p wireless n card, this works absolutely fine under windows, but I also bought it due to reviews saying it worked with linux. The card appears in network settings as RaLink WLAN controller and uses kernel module rt2800pci, I have also tried typing in the network ssid etc manually but it hangs on exiting network manager (will post what it says later, after writing this) I used drivers from here:Ralink corp., and used the rt3062 one(5th one down?)
for lspci
Code:
00:00.0 Host bridge: Intel Corporation 82X38/X48 Express DRAM Controller (rev 01)
00:01.0 PCI bridge: Intel Corporation 82X38/X48 Express Host-Primary PCI Express Bridge (rev 01)
00:06.0 PCI bridge: Intel Corporation 82X38/X48 Express Host-Secondary PCI Express Bridge (rev 01)
00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02)
00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02)
[Code]....
I have also had the same problem of not picking up networks in Ubuntu, not sure if the drivers are 64-bit compatible or something.

I went out and purchased a Sabrent PCI wireless 802.11n card with the RT2860 chipset because it was on the ubunutu compatibility list and has linux driver available from the manufacturer. I was impressed that the card worked in wireless G mode out of the box, which is a great start....
However, I can't find any wireless N networks. Dual booting I can find/use my N network, but in ubuntu I can only find my G network. This is somewhat frustrating because I bought this card and a new (read: expensive) Linksys E3000 router specifically to run a nice new N network...
I have downloaded, made, and installed (reboot) the latest driver from the manufacturer, but it still won't find any N networks. I found a few posts by searching here and google that alluded to changing this line: "HT_OpMode=1" (from 0 to 1) in the config file RT2860STA.dat located in /etc/Wireless/RT2860STA/ and a reboot. It didn't work for me.
Frankly all this rebooting is starting to **** me off ... I have spent most of last night trying to setup my 180$ wireless network and its still no better than the freebie DDWRT54g based wifi it replaced. I am frustrated, perhaps someone wiser in the ways of ubuntu and wireless N can shed some light on the situation....
I forgot to mention I am on Karmic Kola, amd64 with the standard gnome.

i'm running ubuntu 10.04. i've followed these instructions:[URL]that got the light for the wireless on my laptop to light up but it doesn't seem to be able to find any networks.when i click on "connect to hidden wireless network" and enter the details + encryption code. it spends a few minutes trying to connect before asking for my encryption code again but i know that the code i entered is right.i'm using a belkin router with wpa/wpa2 encryption. but i think it's a problem with the wireless on my laptop rather than a problem with my specific network because under windows on other machines in my house i can see some of my Neighbours networks

I am fairly new to linux, I getting to grips with the offline and I am starting to be converted. The major problem I have is that I cannot get it to connect to my wireless network. I am using Fedora and my wireless card is the Belkin Wireless G Desktop Network Card - F5D7000uk (version 3000uk).
I am able to see the network and pick up the essid automatically through networkmanager or iwlist scan. I have tried to connect using Network manager:
- it picks up the information and I submit my WEP key and the icon top right shows two green dots with a blue flame(?) rotating between them for a few minutes before asking for my key again.
And using the terminal commands.
Code:
$ sudo iwconfig wlan0 mode managed
$ sudo iwconfig wlan0 essid "BTHomeHub3-12GT"
$ sudo iwconfig wlan0 key 563865428
then tried to test the connection using
Code:
$ sudo ping www.bbc.co.uk
ping: unknown host www.bbc.co.uk
Code:
sudo iwconfig wlan0
wlan0
IEEE 802.11bg ESSID:"BTHomeHub3-12GT"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B

I bought a Letux 400 mini netbook and it works fine except for wireless Ethernet. It finds wireless networks, including mine, and then pretends to connect, after asking for a password, but finally never connects. I tried reconfiguring the wireless network from g to b/g and finally to b only, but nothing changed. Cable connection works. Unfortunately all relevant Letux Web pages are hopelessly slow and certainly too slow to use the forum and ask questions there. why the thing doesn't connect and how to make it connect? If it recognises networks, shouldn't it be able to connect as well?

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 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'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 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 installed Debian Lenny on my new laptop, I uninstall network-manager and install wicd but, it looks that wicd when it scans for networks doesn't find any networks and I don't understand why. I look over my sources.list and it looks ok, then I check the lspci command and my wifi card is detected by the kernel because is an Atheros card, also I install madwifi-tools.

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 have a fresh install of Debian 5.04 Stable. It detects my wireless card with a RT61 chipset and gives me the option to select a wireless network through the network-manager icon in the upper panel, yet no wireless networks are displayed. So, how do I fix this and get the ability to connect to my network? I have tried connecting manually but it refuses to connect. No errors, it just does nothing and reverts to roaming mode.
I believe the exact model of my card is an Edimax EW 7128G.

I upgraded to Ubuntu 11.04, and the wireless was working fine until now when it does not recognize anything and says "No wireless networks found".f I plug the cable into my laptop, then it works (that's how I am communicating right now). I am not sure what the problem is, hardware or software.

I just installed Lenny and I was getting settled in. The wireless didn't work, but I have this USB adapter and was going to use it as a stop-gap measure until I get the real wireless going, especially since I could use that connection for downloading, forum search, etc.However, the USB adapter isn't working either. It seems to detect the adapter itself, since the "appendage" that appears on the right-click menu appears, but there's no detected networks. I have Jaunty dual booting with Lenny, and I know both the network and the USB adapter are working, since I'm on the Ubuntu side using both right now
