Ubuntu Networking :: No Wifi Networks Showing Up?
Feb 27, 2011
got a dell inspirion 15r (i think), and it comes w/ win7 (I HATE Win7) so i made him let me dual-boot with ubuntu maverick meerkat. (he wouldn't let me get rid of win7 cuz thats what his parents use.) It installed successfully, so we booted into it, and there was no wifi networks. I thought it was because wifi was disabled so i press the button i think its F5 but still nothing. I thought it might have been the comp but i booted into win7 (Que the Beethoven's fifth)... and it worked in win7 (thats a first) can someone help me. Oh and i forgot i used that terminal command to unblock wifi

I just bought a new toshiba c655 laptop and had windows 7 on it. i made the dual boot partition on it, yada yada yada, anyway, on the windows partition i can see two networks at my house. one is mine, one is my neighbors. but when i go to the ubuntu side of things not a single wifi network shows up. i did a little combing of the forums and decided to try installing the ndisgtk package which i obviously need internet for. i thought i would plug it into an ethernet cable running straight from the modom and i could connect and download no problem. however. this has turned out to be quite a mistake. ubuntu does not even recognize the fact i have an ethernet cable plugged in. this may or may not be related, but niether my ipod or my cell phone does not show up when i plug those in and when i try to mount them i get an error message that says they could not be found. Im running 10.04.

I have ubuntu 10.10, and at my house I primarily used wired, and it works fine, and under windows earlier today I was able to locate networks, so my wireless card is working. I'm currently at my girlfriends house, and trying to connect to her wireless internet. When I try to connect, I can't find any networks. I've made sure her network has sharing and discovery enabled, however in my wirelss manager it comes up as blank. There's the option to add wireless manually, but do I really need to go through the trouble of finding the routers mac address and all that, it should just show up?I could switch back to windows to see if I can connect, but I'm almost positive it's just the linux wireless manager..

I arrived in the Central African Republic only to find that my wireless (on an HP Mini 5102) wasn't working -- it didn't detect any wireless networks. So I wiped off Windows and installed Ubuntu 10.10, Luckily, it did! (Partly.) At first, I still didn't get any wireless networks. I messed around with all the various things you have to do to get Broadcom wireless drivers working. Finally, following a forum suggestion, I installed Wicd -- and this did the trick. Not knowing any better, I kept Network Manager alongside Wicd, but Wicd is what works much better. (Is there a reason to un-install Network Manager?)
However, when I try to connect wirelessly to the network at this country's one cafe with wifi (which usually works really well, by CAR standards), the network doesn't appear. At the office, when I open Wicd, it includes a box with the message "<connection name>: obtaining IP address", and bit by bit it connects. But when I open Wicd at the cafe, this doesn't happen -- it just gives me a list of random signals from nearby offices (all secured and low-signal), none of which I can connect to. Any ideas how I could get the cafe network to show up?I'm at the office now, and so it's working. However, in order to get it working I had to restart three times -- Wicd only seems to work about half or 33% of the time. Sometimes I get the message: "Connection failed: unable to get IP address" and sometimes I get the message "No wireless networks detected." Then I try again and eventually it works. So far.

I can normally connect to most wifi connections, but for some reason I can't connect to my broth's-gf-parent's network. Windows 7 can connect to it just fine, but not Ubuntu. Once in a while I'll go to a cafe, and this will happen there too.hough, like I said I can normally connect to all other wifi networks with no hassle

DELL Inspiron 1501 Broadcom BCM4311 is the wifi adapter.The problem I am having is that I cannot get to search for wifi networks. It looks like the driver and everything is there but the wifi is disabled for some reason.I installed the drivers provided by the "Additional Drivers" application and they do not work.I also followed this fix and I could see in the menu that the wifi was added but I was not able to click it or look for wifi's URL...

I was on a car trip earlier, but we were stuck in traffic. The stop-go stop-go kind of BS. I pulled out my 9.10 laptop and figured I'd scan for wifi networks and see how good America was at securing their networks. (I work in IT support so it's one of those things I preach to no end yet people rarely listen).
I was using wifi radar, and picked up a truckload of networks every time we'd stop. But something didn't sit well with me. When I click on the network manager icon in the top gnome panel to see what networks were available, it never seemed to refresh.
Example - the first 5 networks I saw were 1, 2, 3, 4, 5. We would stop-go more and more and miles later when I'd see more networks in the area show up in wifi radar, yet hit my network manager, I'd STILL see networks 1, 2, 3, 4, 5 and not 30, 31, 32, 33, etc like I expected.
What kind of refresh time or cache or whatever does network manager have? I just didn't understand why I was seeing the original networks from 15 minutes/miles ago and it never seemed to update.

I'm using Ubuntu 10.04 - 64bit install with an A215. The wifi was working fine until today. Ubuntu seems to detect the hardware, and it shows the interface as being 'up', however no networks show up in either the network manager or 'sudo iwlist scan'. I'm not sure if it's a driver issue, or if the hardware itself died.Here is the output of lspci:
ubuntu@ubuntu:~$ lspci
00:00.0 Host bridge: ATI Technologies Inc RS690 Host Bridge
00:01.0 PCI bridge: ATI Technologies Inc RS690 PCI to PCI Bridge (Internal gfx)

I have no problem with my wireless network at home, or visiting friends, but it won't connect to public, open, unsecured WiFi networks, eg hotels, trains, ships.I'm using Ubuntu v9.10, NetworkManager applet v0.7.996, on a Dell Inspiron 1750 laptop.If I left click on the NetworkManager, the available wireless networks are displayed and I can see the relevent open networks, named as expected and shown without the lock icon. I click on the relevent entry, watch a spinner for 30 seconds or so and then it drops off and I have no connection. This happens for "all" open connections.If I look at my defined Wireless Network Connections now, I can see, eg, "Auto Internet@Sea, Last used: never". Editing that connection:

SSID: Internet@Sea
Mode: Infrastructure

Fedora 10 (dual boot w/ XP) on Dell Optiplex with a Dell wirelessntennaI am on a university campus with campus-wide wifi network (so no router). I have a wireless HP printer that I want to be able to print to using an ad-hoc connection. The wireless antenna, networking, and wireless printing are all working in Windows XP (so hardware is OK). However, on the linux side, the wifi is really really finicky.
When I first boot up to fedora, it usually connects no problem to the campus-wide wifi network. If I try to switch to the ad-hoc printer network (which it sees), will not connect and, furthermore, it will no longer connect to the campus-wide network (and sometimes it doesn't "see" this network at all). It seems that restarting the Network Manager service sometimes helps to reconnect to the campus-wide network, but not always and I can't connect to the ad-hoc regardlessNOTE: I'm just barely a linux user, and I didn't set up my system - don't assume that I did anything that would be common sense and, if you can, walk me through your suggestions.

I have been an Ubuntu user for a year or so. My level is still ultra n00b but I am trying. Whenever I update Ubuntu there is always a WiFi problem, always. So now I am having problems getting wifi to work in 10.10. In Network Manager I can view wifi networks fine but I cannot connect. I tried with wicd also but I got as far as "getting ip" and then it would hang up.

Code:
I am not sure what driver I am using as I don't know how to exactly ID my driver. I know there is a way to ID the driver using airodump-ng but I have yet to find it.
I have a feeling this is a driver issue as one time I was able to establish a connection that then dropped a few minutes later. I have a feeling I should be disabling/removing the current driver and replacing it with ipw3945 or possibly a driver ndiswrapped? The problem is I cannot figure out how to remove the current driver.
I was going to switch back to 9.04 but I thought I would try to manually figure this one out instead of taking the easy way.

I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.

I have installed Ubuntu for netbooks on my four year old laptop and of course the wifi card is unable to search for wireless networks when I'm booted into Ubuntu. I do have the driver software on a recovery disk. Would installing it in Ubuntu fix my problems?

I have Lucent Technologies Orinoco Silver 11 Mbps PCMCIA wifi card. It worked perfectly in Fedora 10, but after updating to Fedora 11 it stopped finding any wireless networks. The updating were done with automatic updating utility. The card works perfectly in Windows, I tested it today.
My laptop is HP nx6110 if that matters.
Here is the situation:
When I plug-out the card, the Network Manager disables wireless networking as it should. When I plug-in the card, wireless networking is enabled, so the system seems to recognize the card in some way.
If I try to connect to "Hidden wireless network" (because there isn't any wireless networks listed in the Network Manager) system tries to connect for a couple of minutes, and then asks wireless settings again. Orinoco card's lights DOESN'T blink normally when connecting to the network (one light should blink rapidly and one should light continuously, but both are blinking rarely or doesn't blink at all).
In System->Administration->Network in tab Hardware (hope those names are correct, I use Finnish version of Fedora...) is:
It seems that the card is detected right.
Here is what I have done to get the problem solved: In System->Administration->Network I have tried to connect to the wireless network manually (disabling the Network Manager). I can't get the connection. It gives me random error messages, sometimes "Check the cable" or something like that, sometimes just timeouts IP determination.
I have tried to connect different wireless networks, no connection. All tested networks worked with another computer.
No matter if I reboot or service network restart or plug-out plug-in the card... the problem still appears.
Tried to find (and reinstall) drivers:
Code:
No Matches found
Code:
Here is the output of lspci. The output is the same if the wifi card is connected or not.
Code:
LAN connection is working just fine.

I have been working on this problem for a while but might be narrowing the options. This is an HP laptop running Ubuntu Koala. Until last week, the wireless had been working perfectly but suddenly it lost the wireless connection (to a Bell modem/wireless router) and all local wireless networks had disappeared. These two command listings below may hold a key but I know nothing about wireless and not much about Ubuntu. What seems odd is that "lshw" shows the wireless interface as logical name "wmaster0" but the iwconfig shows a "wlan1" as the wireless. The ethernet wired interface shows as "eth1" on both commands. Could this be causing the problem. Also, I was wondering what the "ACPI handle has no context" means.

I upgraded to Maverick over the weekend from Lucid, and at school yesterday, I could no longer connect to the campus wifi network in my office. I have no problem connecting to the wifi network at home, and my phone still sees and connects to the campus wifi network, so I think the problem is with my laptop (Gateway T-6345u), which doesn't even detect the campus network. As of last week, it connected automatically, and now it can't even see the network.

My server name, salamander, is not showing up in windows networking or in the networking items on linux computers. I have checked, double checked and tried several samba settings to see if I can make it work, but to no avail. Its shares can be accessed by any computer by going directly to 10.10.1.101, salamander's fixed IP.
My workstation, bear, shows up. I edited hosts to read: "10.10.1.101 salamander"
Any machine can access the share on salamander using the ip address, but not even Bear can connect directly with the computer name.
When I go to networks in Salamander, all it views is itself and a windows network. Inside the windows network is only salamander.
Bear shows up in the list of servers, and also has samba running. Eagle and Bearcub are also ubuntu without samba and do not show up in the list either. Understandably so.
Here is my smb.conf:
Code:
[global]
workgroup = WILDLIFE
server string = %h server (Samba, Ubuntu)
security = SHARE

I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.

following a new motherboard install I've just done a clean install of 10.10. At first, I was using the default network manager wifi to connect to my router - I had the upturned radar beam type icon in the top panel showing me the strength of the signal and access, by right clicking on it, to things like Enable Networking, Enable Wireless, etc. I read that installing WICD via synaptic would install wicd and remove the default network manager, so this what I did. My wifi is OK but I still have my upturned radar type icon and a new WICD icon in the top panel. I was expecting the upturned radar icon to disappear - is this correct? If I right click on the radar icon I can click on the Edit Connections option and change things - it appears I have both the default network manager and WICD working at the same time.

I have FC 12 running and everything was working fine for about 2 weeks or so. Then today after I put my Daughter to bed, I booted up the laptop and it could not find any of the many WiFi networks that are present in my area, and when I tried to get it to connect to my home network through a saved configuration in the Network Connections Manager it kept asking for my WPA2 Password but it would not connect. So I got out my delopitated Cat-5 cable and tried to do an update and see if that would solve the problem. But alas it did not work (hence the posting of this tread ).
I even tried to unload the "B43" driver using code...
But that did not do the trick either. Is there any way to get it to work again without doing a re-install of the entire Operating System? I already had to do that, and it is a big pain in the A$$ because of a defective ATI Card in the laptop.

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.
