Ubuntu Networking :: 10.10 - In Network Manager Can View Wifi Networks Fine But Cannot Connect
Apr 28, 2011
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 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 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 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 use network-manager-gnome to connect to my wireless networks, but I can only use it with a graphical environment, and it doesn't even work that well since it will drop the connection after a few minutes and I have to reconnect it manually, that means I cannot leave my computer downloading a big file all night since it will only download for a few minutes, does anyone know what package can I use to connect to my wireless without the need of network-manager, even if it's through command line?

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

I'm trying to search for more wireless networks but i cannot find a way to make network manager search for more wireless networks. It only displays 2 wireless networks and none of them is mine, even though I've got my wireless router at less than 1 meter from my PC.

A couple of weeks ago my laptop's wifi started acting up, to the point that it didn't function. When I click the nwManager icon to being up a list of available networks, it is empty. If I try to create a new network, with the credentials of my modem, it appears to work, and asks for the password. After I enter the password, it seems to work for about 30 seconds (much longer than normal) but then it prompts me again for the password. This cycle continues indefinitely.
I'm running Karmic on a Dell i1525. how to find out what wireless card I have.

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 have been running FC8 on this IBM T23 with a D-Link wireless adapter. Using MadWifi this has worked fine with Network Manager disabled. But now I have nuked that installation and replaced it with FC10. Network Manager is nice, and I would like to use it. And it kind-of works. Network Manager recognizes my router and all my neighbor's routers, but I can't connect.

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.
iwconfig:
wlan0 IEEE 802.11bgn ESSID:"MyHomeRouter"
Mode:Managed Frequency:2.447 GHz Access Point: 00:22:2D:06:2C:50

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 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:
Code:
#!/bin/sh
case "$1" in

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 freshly installed Jessie on my Dell Inspiron 5110, I configured the network on the installer and had no problem. I can browse the web, get updates and install software.
But I can't find new networks. It just show "No Networks".

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 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.
ubuntu@ubuntu:~$ lspci
