Ubuntu Networking :: Wireless Connections Not Found
Nov 10, 2010
I have an Acer AspireOne D255 netbook. I just installed Ubuntu Netbook Remix 10.10 and it looks pretty sweet.Right now, I'm on a wired connection. It's not detecting any networks, and I know at least my home wifi should show up (and usually we can get onto our neighbors!)I used to have a different model of an AspireOne (I think it was 531h but I'm not 100% sure) with UNR 10.04, and my network was detected right out of the box.
This reminds me of when I installed the desktop version of 10.04 on my iMac. I couldn't bring the wired connection to the room it was in, and my wifi didn't show up on it. I just gave up because I like my Mac so it wasn't a *huge* deal. but I definitely don't want to use this stupid Windows 7 Starter that comes on this netbook!

I have been using Ubuntu for a couple of days now and I am starting to like it alot. I decided to install it on my laptop, but getting it to connect wireless is becoming a problem. I have been searching all day on how to fix this but nothing so far has helped.I had Windows 7 installed before and it connected fine.

So it snatched up this old Dell Inspiron 5100 with a WN511B wifi card. When I plug the card into the slot nothing happens and no wireless connections show up. Can someone walk me through on getting the wifi card to work?

I went to get online on my laptop this morning, and have no connection. When i click on the icon up top in the task bar, it only shows vpn connection. It does not show ANY wireless connections at all. I checked, and the enable wireless is checked. It just does not pick up any connections.

I own an hp dv9000 laptop, it comes with a Broadcom STA Wireless card... I currently have my laptop connected to the internet through a wired connection, but there is no option at all for wireless.I've already installed the Additional Drivers to install the Broadcom STA Wireless Drivers, and after I reset, there was no difference, no option to choose wireless instead.

I'm working right now with ubuntu 11.04 on my asus ul30vt-x1, my wireless n network is working on a linksys e3000 router, my issue is basically with long file transfers. When the issue started i was reaching speeds of 100 Mbps through my wireless network even when I'm connected at 150 Mbps. However when at this speed, I don't know why, the connection is dropped after some minutes or even seconds. I made some testing on windows, I'm reaching 70 Mbps there and no problem at all with dropping the connection.
So my conclusion is that for some reason the linux driver, in my case, is not able to handle such speed of 100 Mbps. I know that a wireless network will have a throughput of aprox 60% the wireless speed. Right now im trying to apply traffic shapping to my transfers so i can get 70 to 80 Mbps, its being working so far.

So my machine is doing a bunch of strange things and I want to reload it. But I would like to save some of my settings, the most important of which to me is the wireless networks that I've configured from all my customer sites. There are A LOT of them, and I don't remember all of the settings so it would be nice to migrate those to my new install without having to redo them one by one when I arrive at a customer site.

Running Ubuntu 10.10 on a Dell 710m. Fresh install of OS yesterday. Initially I had wired connection but no wireless. So I started chasing threads & trying different downloads & commands [WITHOUT KNOWING essentially what I was doing; throw your rocks at me HERE] & now I have lost the wired connection also.
Also:
[a] If I go into System > Administration > Additional Drivers, I get "No proprietary drivers are in use on this system."
[b] As far as being able to copy a downloaded driver [using a working M$oft machine with net connection] onto an SD card & transferring that driver to the Dell laptop, I have tried formatting 3 different SD cards with the Dell, & each time I come up with various failure errors--& I have no idea why something as simple as formatting an SD card isn't working.

Can anyone tell me if there is a way to change the behavior of Network Manager, so that it will only automatically connect to certain wireless networks which I specify, and not automatically connect to others I may have previously used. For example, there are a lot of wifi networks called "linksys", and I don't want the program to automatically try to connect to whichever one it finds.If someone can tell me in which file(s) the list of these connections is stored, I might be able to write a script which will edit that list on startup.

i'm using a dell n5010 recently i installed ubuntu9.10 in my laptop and it doesn't seem to detect wireless connections, so, i googled it and downloaded a driver from broadcom and tried to install it as per the authors instructions and nothing seems to work well, the broadcom drivers are not detected in the additional drivers and when i try to install linux-wlan-ng tarballs it doesn't seem to work even, though i have gcc(i think thats it), so, i installed my windows driver through nsdgtk but it says that it is "unable to see if hardware is present" but, when i click ok on the error the wireless network applet says the hardware is present and when i click the network configuration tool it gives the error message "could not find a network configuration tool" and after configuring my network with network tools in administration it says "no wireless extensions" when i type 'iwconfig' and there is no ip address when i type "ipconfig".

I'm getting really tired of using windows, I love ubuntu but theres a big problem. I have a BTHomeHub2 and whats annoying is whenever I goto wireless connections there's only a bt home hub but its not my one. and I have tried connecting to hidden wireless network and nothing worked. I have a desktop pc with a usb plug in BT voyager that picks up the router but it will only find the one down the street not mine. It works fine when using Ethernet.

My current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.

What I want is quite simple, I have my PC running Linux Mint 5 (Elyssa), and I would like to connect it to both an internal network, which has a file/print server, another machine and will soon host a small cluster. I also have a wireless router connected to the tinterweb.
The thing is using my ethernet I want to connect to the internal network whilst simultaneously using my wireless to deal with the internet, I want to keep the internal network off the net as it really doesn't need to be connected. I can connect to my internal quite happily and also my wireless but not both at once.

Just had an issue crop up where connecting wired network seems to stop wireless connections from getting an IP (happens on multiple networks both while the cable is plugged in and once it's been unplugged; also persists across reboots). Machine is a Dell Latitude 2120n with UnionFS running. Connection was working fine prior to the wired connection

I installed Nvidia drivers according to the post in HowTos section. It downloaded a different version of the existing kernel, i guess. And the kernel using which I downloaded, when shows up GUI, looks like a Safe Mode of Windows. So I boot the kernel that it downloaded. And there the problem is that in Network Manager applet, it doesn't show me the wireless connections. It doesn't even show the Enable Wireless checkbox upon right clicking it. How to get it back?

My wireless is flakey -- dropped connections, poor speed, etc. As diagnosis, I loaded the 'wavemon' utility so that I might watch the radio and signal and noise.Things will be good, then fall off, then get better, then go away entirely. Repeat continuously and randomly. For these experiments, my laptops -- more than one -- are on a table.The table is roughly 15-20 ft laterally from the access point. The access point is also 8 ft above the floor vs. 3 ft table height.(grin) While the signal "wobbles" everything else is mechanically stable and otherwise not moving.

I'm trying to get wireless working in F10. Using pci wireless card with Atheros chipset. To be sure, I tested this hardware with a PCLinuxOS Live CD. Connects to AP perfectly.
Hardware drivers seem all OK in F10, and ifconfig shows wlan0 as expected. When I use the Wireless-Assistant 0.5.7 there's no connection.
Actually, the AP logs show numerous connections and disconnections.
Preferring CLI, I'm using a drop-dead simple wpa_supplicant.conf as follows :
Should Ipost some debugging output from wpa_supplicant -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d

I recently installed ubuntu 10.4 LTS on my IBM T60 ThinkPad, (Love Ubuntu! Will Never go back to Windows)
But now the problem is as followed.: When i'm at work where they have an open (Non protected) WiFi spot i have no problems connecting at all. But as soon as i'm at home or with friends which have WEP/WPA/WPA2 encrypted routers it is impossible to connect, to none of them. not Linksys, not Dlink not Thomsom, simply none. For days i've been hunting the internet for information about this problem but it is impossible for me to find the solution. I've read the Wireless troubleshooting manual from Ubuntu and did all the checks and tests and everything seems fine. The card is an Intel 3945ABG, and in the new Linux Kernels its already pre-installed. It's so frustrating not beeing able to use the internet in a proper way..
Note:
I installed wireshark to experiment at my workplace but its finding nothing at all even though its connected to the internet/LAN Etherape works fine though.

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 installed Lubuntu yesterday on an older Dell laptop and the installation went fine. The only thing not working after the installation was the wireless. After hours of searching, I was finally about to get it to recognize the wireless card, see wireless networks, and connect successfully by running these commands.code...

I'v tried to uninstall and reinstall wubbi 4 times already. Before the OS even start up it says that it cannot find the wireless kernel and then it boots me up into that start up with the *configuration wizard* and that fails as well and asks me to reboot.How can i get my wireless transfered to Ubuntu without using a flash drive or CD? I thought that Ubuntu would automatically detect my wireless but i see no options as such.

I have been trying to get my Belkin FD8233-4v3 wireless-n usb adapter to work in Ubuntu since 8.04. It has worked with ndiswrapper under 32-bit (never the 64-bit) versions in the past, but has never been able to be configured directly. It uses the Ralink RT2870 chipset, but cannot seem to be configured using the drivers from the Ralink website.
With Ubuntu 10.04 64-Bit, everything has changed. I have high hopes that this adapter may finally work correctly and without ndiswrapper. As soon as I first booted 10.04, for the first time ever, Ubuntu recognized the IF automatically, reported my wireless router, allowed me to enter my 128-bit WEP hex code and tried to connect up. It is failing miserably, but it is making a valiant effort.

Ubuntu 10.04 x86. Yesterday I installed 10.10 and had lots of trouble with wireless stability. I formatted the partition and installed 10.04. My wireless router does not show up in the available routers list. Neither in the list that immediately shows or under the More networks submenu. Lots of other routers from adjacent homes show up, but not mine in the other room.
Why? It shows up on all of my other computers. My MacBook, Windows 7 (different partition on same box), my older Ubuntu netbook,and it showed up on a previous install of 10.10 (though it could not maintain the connection longer than 5 minutes). It will not show up on Ubuntu 10.04. I've tried manually entering the information to connect, but it doesn't see it. I don't know what to do.

I remember that I did configure my desktop PC for wired and wireless connections since openSUSE 11.2, 11.3 and 11.4. Currently I have openSUSE11.4 x86_64 KDE. Today I happen to notice that the icon for NetworkManager in the taskbar has been replaced with a red X. I discovered that Network Manager only shows VPN tab, whereas Wired and Wireless tabs are greyed out. The strange thing is I still have Internet connection with the CAT5 cable being plugged in. I can still configure wired and wireless connections via YAST but I cannot fix Network Manager settings.
