My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password (which I don't know). Is there any way to blacklist a wireless network so that the Network Manager will never attempt to connect to it?
View 4 Repliesi was fed up after i can't connect to wifi using ubuntu. the problem happened after my router is being replaced to a new one because the old one got struck by lightning. good thing i dual-boot my laptop so i can access the internet using Windows 7 now.
i use the default network manager to connect to wifi before, but it all seem to be failed after the replacement of router. i also used Wicd but it failed to connect either. it says in the notification "disconnected: bad password" but the password was right. my wifi used WEP password with open authentication.
i even remove the WEP password and try to connect, but it failed. all i can do is to boot in windows 7 and surf internet there. what could cause this problem? is it the router, the telephone line? i can set the router settings if i want, but i don't know what causes the problem.
I happened to Fedora 13 that the network manager does not indicate any wifi network and I had to turn off the notebook for a while and then recover, this also happened to me 2 or 3 times on ubuntu 10.04 too. my card is an Atheros AR5007EG.

I thought it was ok, since I use the wifi only for accessing the internet. However, the network manager keeps dropping the signal, and I can't understand why. I'm close enough to the router.

I have eventually (a week's work) got my Ubuntu 10.04 to recognise my Asus N13 WiFi dongle (had to compile the source from Ralink with the "y" against the two things it tells you to if you want network manager to work (source that came with dongle wouldn't compile) and then set up rules (for some reason the driver - rt2870sta - wouldn't recognise the dongle until the rule about the vendor and product ID was in place; and the drivers that come with Ubuntu wouldn't recognise it even with the rule in place)).
Big thank you to chilli555 for all of the posts that got me this far.I would like to use the Network Manager app that comes with Ubuntu, to control the dongle. At the moment it will aknowledge when the driver has been loaded (have to do a modprobe), but does not "see" any of the many WiFi routers around my house, so I can't click on one to select one.
My only guess on this is that, to get the dongle to work I copied the config file that is part of the driver source files into /etc/Wireless/RT2870, and this is getting in the way. However, I have tried removing it and the network manager still doesn't work. Or is it because the network manager needs the dongle to be called "wlan0" and it's called "ra0"? If so, can you aliase this?
I just installed F14 today, all day I have been trying to get my wifi to work, I keep running in problems I found many threads with links to download drivers. I did that and in the README file loses me. It talks about compile driver from the source code.

I have a Ubuntu 10.04 laptop that gets its Internet connection via WIFI using WICD as network manager, and Windows XP desktop with no Internet connection. What I want to do is share my Internet connection from my laptop with my desktop via a Ethernet cable. But i have no idea what to do. How do i go about doing this?

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.

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 just installed x64 Fedora, and as the title says, NM fails to detect my WiFi card. It's an Encore ENLWI-N with a RaLink RT2800 chipset. The card does show up when I run lspci, although iwconfig yields nothing.Not sure if this helps, but when Ias running Karmic Koala, Ubuntu detected the card immediately and required no configuration
View 2 Replies View RelatedI recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:

I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.
View 4 Replies View RelatedI have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
View 4 Replies View RelatedI recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.
I upgraded from 9.0X to 10.04 on my Sony Vaio VGN-TZ398U which has an internal Sprint mobile broadband card. The card operates properly along with the wireless. The problem that I am having since upgrading is that the Network Manager Applet icon that looks like a cell phone bar display does not show in the notification area at all unless there is a known wireless (wifi) network nearby.
Clarification: If I am in my car, the icon does not show which then makes it impossible to connect using the mobile broadband functions of the Network Manager Applet ( version 0.8 ). If I am in my office with a known wireless network, the icon shows and then I can switch to the mobile card.
I have tried removing the notification area from the panel and adding it again. I have done the same with the indicator applet. Neither has solved this problem.
I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.

I dual boot this laptop with Windows 7, and on Windows, I connect to the internet instantly after boot. I did not have this issue before, the only thing I have changed was installing blueman and the necessary components.

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

I often use an Ethernet cable to connect my computer to another computer for various purposes. But when I do that, I cannot use the internet even though I'm still connected to a WiFi access point. I'm presuming that's because openSUSE is trying to reach the internet through the Ethernet cable, which has precedence over WiFi.Is there a way to enable internet usage via WiFi while I'm connected to another computer over Ethernet?

How do I choose a wireless network to connect to? The Ubuntu 8.10 help tells me to open NetworkManager, but the only thing I can find is 'Network Configuration' in System>Preferences. If I try to run NetworkManager in usr/sbin as a root, nothing happens whatsoever. nm-tool lists several available Access Points for my WiFi antenna.
View 2 Replies View RelatedSo recently we switched Internet Providers. While we had Bellsouth, my laptop would connect to our wireless internet flawlessly everytime. However, we just switched to Charter because it was both cheaper and faster. But now, my laptop will not connect to our wireless. If I hook it up to an Ethernet cord, it connects just fine. I believe they gave us a new modem/router or whatever it is that sends out the wifi signal.
I have tried to connect with this laptop on Ubuntu, Linux Mint, and Backtrack 4. On Ubuntu and Linux Mint, after I enter the correct WEP key, it sits there and tried to connect for a minute or two, but then the window pops up asking for the WEP key again, even though it's still filled out.
When I tried connecting on Backtrack, it told me that it could not obtain an IP address.
when it boots it doesn't ask me for my password (not the one to WiFi network, but the one to 'default key base') and because of that I can't connect to my WiFi network. The network itself is working fine. So i restart my computer (sometimes I have to restart it 15-20 times) and finally Ubuntu asks me for my password I type it in and everything works fine. what should I do with this?
