Ubuntu Networking :: Can't Connect To Wifi Using Any Network Manager
Dec 26, 2010
i 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 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 can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
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?
I've got a Belkin F5D8055 v1 wifi usb adapter. I use the rt2800usb driver for it. Strangely it uses only 54 Mbit/s instead of 300 Mbit/s. 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 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 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.
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 just installed 10.04, just migrating to linux. I can't see the network manager anywhere. I have the applet installed. I can't get the wifi adapter enabled. The chipset iwl8345 shows on the output when I run config. It seems to me that I need to get the NM up and that should doit. here is ishw:
I 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.
So 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.
about 90 percent of the time, i cannot connect to the internet. i click on the icon and select the network, but for some reason, instead of saying, "connection established", it says, "you are now disconnected."
I just installed Ubuntu on my laptop and I found that I cannot connect to my school's wifi network while i have no problem connecting using windows. Also I can connect to my home's wifi network. The details of the wifi network are as follow:
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
I have a Fedora Box with chillispot loaded for a captive protal wifi network. I am needing my office lan to connect to a controller on the WIFI network. I have tried many different firewall rules and have only momentarly able to ping something on the other network. here's some configuration info and my firewall rules that I thought should work.
FC 4 ETH0 - WAN (office lan 192.168.24.201/24) ETH1 - LAN (brought up as 192.168.10.1/24) tun0 - chilli 192.168.240.1
Im trying to connect to my wireless network via terminal. My wifi network has a WPA2 encription. Im running ubuntu server 10.04. wifi interfaces are active, i can "see" my network with airodump. The only thing is i dont really know how to configure my iwconfig to connect to it.
I got my netbook in the mail yesterday, opened it up, logged in, and Windows 7 was installed. Being a Windows hater my whole life, I followed a friend's advice and downloaded Ubuntu netbook, made a USB drive, changed the BIOS settings, all that. Here's when the stupidity occurs--I decided to go ahead and install Ubuntu without trying it, and to delete Windows to do so. A couple minutes later I realized that was a really, really stupid idea, so in a panic I turned my netbook off. I turned it back on and it was still on install but not really moving, so I powered off and on again and went back to the "Try Ubuntu" or "Install Ubuntu" choice screen. I chose "Try Ubuntu" and found that it did not recognize my home wifi network or ask me to join--or any wifi network, for that matter.
Now, it did recognize my wifi network the few minutes I spent on Windows 7, so I tried to change the BIOS settings back to where I could just use that until I figured out the problem. But no matter which setting I tried (HDD/SDD just gives me a black screen, and FDD and LAN do the same as the USB drive), I can't get back to Windows, so I guess I did delete it. Which leaves me with a netbook that can only connect to the internet via ethernet cable. Which kind of defeats the purpose.
Questions I should answer:
1. How am I trying to get online? My home's wireless network. We have a router. All the other laptops in the house connect fine.
2. Who is my internet service provider (and in which country?) COX, United States.
3. Can you get online with any other method? Yes, the internet works fine with an ethernet cable.
4. How am I getting online to post in this forum? My parent's laptop.
5. What hardware are you using? Toshiba N505 netbook and a router. I can give more information about the router if you need it, but I doubt it's the program since the other laptops are fine.
Give me one moment and I will add some code that it gives me when I put in the commands this website tells me to.My two final questions are:
1. Is there any way to recover Windows without buying it again?
2. How can I get Ubuntu to connect to my home wifi network?
EDIT: Here's some code. I have no idea what it means, but hopefully you do.
To run a command as administrator (user "root"), use "sudo <command>".See "man sudo_root" for details.
I'm running Ubuntu Karmic Server with Xfce desktop, the problem is the network manager, it says it is disconnected, even though I am connected to my network and getting an internet connection. It wouldn't normally bother me, but I'm trying to setup a VPN using the network-manager-openvpn plugin. I put in the required details for the VPN connection, but as soon as I tick the "apply to all users" box, the information is lost. The information will remain if I don't tick that box, but it will not connect. when I try to select the VPN connection I just setup, nothing happens.
I've tried the exact same configuration on another desktop, running Ubuntu Karmic with Gnome desktop, the network manager works fine, my ethernet connection is showing as connected, and I can connect to the VPN no problem, the problem lies with the network manager in Xfce. Is there anyway I can get it to show as connected? it wont allow me to connect to the VPN otherwise, it's silly, because that adapter has a full working network connection.
I'm trying to use wicd instead of network manager because I want a "no fuss" way to use wireless on wmii. However, wicd will not find any networks unless network-manager has been run and has connected to a network since startup. If it hasn't connected to a wireless network, the wicd will find no networks, and iwlist won't provide a list of networks either.
This seems to mean that network-manager is doing something to the interface when it connects that needs to be done to make it usable, but I'm not sure what it is or how exactly to find out. I do know that the interface (eth2) will not appear in ifconfig if network manager hasn't connected, which I assume means that it hasn't been brought up. ifconfig eth2 up makes it show up, but I still can't connect with wicd. What can I do?
I'm running Ubuntu 10.04, generic 2.6.32-22 kernel, MacBook 5,5 using the Broadcom STA driver. (more details below)
I followed (or at least tried to follow) tutorials on doing this. I installed network-manager-pptp and tried to configure network manager to connect to a VPN. In the settings when I select MPPE with 128-bit encryption, after I've selected it and applied it, I check the settings and it's invariably unchecked. I tried using KVpnc after getting frustrated with network manager, and I can't seem to get that working either. I've been trying to search for info on this, and I can't seem to find anything on why I can't select MPPE with 128-bit encryption. That seems like it might be why I'm unable to connect to the VPN?
I have a problem with network manager. I use Ubuntu 10.04 on a Dell Latitude D530. I used to have the same problem with Ubuntu 9.10 before I upgraded. I typically connect to two wireless networks: HOME and WORK. Both networks are set to automatic connection mode. I am at work, I connect to the network WORK. At the end of the day, I just close the lid and go home. At home, I open the lid and have the following problem: network manager still displays the network WORK whereas it is clearly out-of-range and it automatically tries to connect to it. It does so until network manager asks if the password is correct.
If I want to connect to HOME, I have to tell network manager to do so. Then, I receive a notification that I am disconnected to WORK. Next morning, I go to work, and I have the same problem, network manager tries to automatically connect to HOME. What I would expect from network manager: when I am at home, NM automatically connects to HOME and does not display WORK, when I am at work, NM automatically connects to WORK and does not display HOME.
I have ticked the box Connect Automatically in the OpenVPN setup I configured in the gnome network manager but it doesn't connect on startup. It connects perfectly ok if I manually select the VPN but i'd like it work immediately on launch.
I have autologin on Ubuntu but since there is no VPN password to decrypt I don't see why it should be a problem.
I am running Ubuntu 10.10 Netbook Remix on a Toshiba Netbook NB300. After performing an upgrade I find myself unable to connect to my wirless network and have lost the wifi icon in the task bar. Ethernet connectivity is however working.
iwconfig shows: wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off ifconfig shows
I need to take to bring back wireless connectivity to my netbook and restore the wifi icon to the task bar.
I am trying to connect my Asus EEEPC to an option icon 431 usb modem.
I have successfully installed the HSO driver however am unable to connect through network manager. I have successfully connected through Rhel Beta 2, Fedora 13 and Ubuntu 9+, however, desperrately want to be able to use centos 5..5
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 WvDial (apparently) but it has no icon or launcher to start it by default, how do i get it to run? I also need basic set up how to. I am running Ubuntu 9.10 (Karmic) and network manager doesn't seem to be able to use my modem to connect to the internet (set up wizard works, appears connected, but then I get page not found error). Hence I wish to use WvDial to try to connect instead.
