Ubuntu Networking :: No DNS For Wireless - How To Start Network Manager
Apr 30, 2010
I have 10.04 installed on my HP MiniNote Netbook. If I plug it into the the ethernet directly, all is well, but if I only use the wireless, i get no DNS servers. And one of my wireless networks is on the same router as the wired connection. Also, wireless works just perfectly on my MacBook Air. So, I do not think it is the router. So why am I not getting DNS addresses? How would I set them manually? I can't figure out how to start network manager.
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 want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4 IP Address: 192.168.1.6 (This is the item I wanted to change and make static) Broadcast Address: 192.168.1.255 Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections" 3. I selected the wireless tab and then the wireless network I wanted to edit 4. I clicked on the edit button and then I clicked on the IPv4 settings tab. 5. I changed method from Automatic (DHCP) to Manual
To start off I have a Rosewill rnx-n2x wireless adapter and a Dlink 4500 router. The problem is, the wireless network manager detects every wireless router in the neighborhood, except mine. I see this persons, and this persons, but no "My router Not yours". I even tried doing the hidden network setup and still nothing.
I have read that the rnx n2x isnt supported by linux, although I've seen solutions to make it work (which didn't work, mkdir command kept getting denied during make) link to what I'm talking about: [URL]. What I don't get though, is that if the rnx n2x isnt supported by linux, wouldn't I not be getting my neighbors connections to begin with?
I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.
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've installed ubuntu 10.04 on a hp mini 110. I've used netbook remix on this same computer and had no problems with a wireless connection. In this case, network manager shows wireless disabled. I have installed the Broadcom B43 Wireless drive from Adminstration->Hardware drivers. No help! ifconfig does not show eth1 and lspci tells me that the Broadcom BCM4312 Network controller is present.
I deleted all APs in my Wireless Section of network manager. After that, the whole network manager icon disappeared. I added the icon back on the panel, but I don't think its the right one. It doesn't do the two green cicles thing when I connect my ethernet wire in. It also doesn't show any wireless AP when I left click on the icon. It doesn't even have an X mark on the bottom left of the icon when no network is detected
I recently upgraded from Ubuntu 9.10 to 10.04 (both 64-bit) and my USB WiFi adapter which previously worked fine stopped working. The adapter is a Hama USB stick based on the Ralink rt73 chipset. I've tried using the Ralink drivers that come with 10.04 (both rt2800usb and rt73usb) but neither work. When I use rt2800usb, the adapter is recognized as interface wlan0, however I can't see any wireless networks. When I use rt73usb (and blacklist rt2800usb to avoid conflicts) I no longer have a wlan0 interface and there is no wireless adapter shown in the network manager. I've pasted in the results of lsmod, lsusb, and ifconfig -a (with MAC addresses removed) below.
So, after doing a 'yum update', I minimized the terminal and completely forgot about it - so I accidentally went ahead and suspended my laptop before it had finished. I resumed my laptop and noticed that yum hadn't finished 'cleaning up' the packages. Nevertheless, yum continued and the process finished. After an hour or so use of the internet (wirelessly), all of a sudden the wireless network disconnected, and NetworkManager crashed. I rebooted my computer only to find that NetworkManager now says that my 'firmware is missing' for my wireless card.
I'm having problems with my wireless card. The network manager won't allow me to turn it on. It is working in windows and in ubuntu, but I can't get it to turn on under fedora. I'm using a Lenovo B570 laptop and it uses the Centrino Wireless-N 1000 for wireless.
Since an upgrade from 10.10 to 11.04, all wireless devices for me in the plasma network manager applet are not functioning properly on a Dell Latitude E4310. Specific problem: No wireless networks appear in the plasma network manager applet. Manually-configured networks do not connect. A separate CDMA card appears, but cannot establish a connection. The CDMA card does function on 10.10 machines, and formerly worked on this machine. The only wireless 'network' that appears in the plasma network manager widget is 'hidden network'. Manually adding a network and checking "Connect Automatically" does nothing. I attempted a fresh install after the upgrade itself failed the work. There are no networks to click on, and selecting the device itself merely shows the status page.

Neither the CDMA card nor any wireless networks are working. If I take the exact same machine and boot from a disk with 10.10, both work.
I am running Ubuntu 9.04 as a partition with windows 7 on a acer aspire 5742, I would like to connect to the internet in Ubuntu, wirelessly, but I am unable to turn my wireless on in Ubuntu, and network manager says "no network connections available". I have the following network adapters:
Where I can get my wireless network running by typing the following lines of code:
Code:
But I have to do this every time I boot the machine. Ideally, I want the machine to do this on it's own at startup.
Also, I'm totally new to linux and I don't really understand what the 1st line of code is doing? The 2nd is just to check that the 1st line worked, and the 3rd does the settings for the wireless network I'm connecting to.
If you want to get into why I have to do this every time, then look at my original thread. But I started this new thread just to find out how I can get these lines of code done automatically at startup.
I am using an Acer Aspire 5536 AMD dual core laptop with a 64bit installation of Susie 11.4. Using 11.2 I had no problems connecting to the wireless router. As soon as 11.4 was installed, clean install, and the laptop rebooted, network manager failed to start, until manually invoked and then enabling networking through the system tray. Even after this it will not connect to a wired or wireless network sometimes for more than 30 minutes.
I have just installed opensuse 11.3. I am absolutely new for Linux and for this forum. I have tried to open Network manager to configure my wlan. But its not starting. How to start network manager and configuring my wlan.
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 looking to replace network manager on my laptop with another wireless program. iv been looking at Swscanner, Rutilt wlan manager, and wicd network manager. iv had trouble with network manager not being able to connect or losing connection fairly easy. im using a gateway m6843 running ubuntu 10.04 32 bit os.
I was editing my wireless network connections when all of a sudden the network connections .. i have tried everything from reinstalling to removing and installing . nothing has worked. i tried installing wicd but i cannot configure wireless networks in it ..
Our corporate wireless network uses continuously changing passwords with RSA tokens.So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked.Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked.Is there some way to prevent it from storing my password for that network?
I recently installed OpenSUSE 11.2 and everything works fine except wi-fi card, of course. The problem is that after installation the system recognized the card (is was listed in network devices in Yast) but I was unable to enable it through network-manager applet. Though the device could make scanning through terminal (found article in docs but didn't fully understand wpa_gui). Then i was stupid enough to delete the device from Yast list to try to reinstall it. So the problem is that i simply can't do this cause i see no way to re-detect. That is the goal is to at least turn back to post-install system state and try to enable wifi card again.
When I attempt to connect to a wireless network, the network manager asks me for the network's password, then says 'setting network address' for 20 or so seconds, then asks me for some random Hex or ASCII key in the same type of window I put the password in (Secrets for Noel -- KDE Daemon). Since a key is already typed into the window, I press OK, which then causes the network manager to go back to 'setting network address', then the window pops up again and keeps repeating itself.
I'm running Opensuse 11.4 with KDE, and my driver is ath9k. I don't know much about linux so please don't tell me to 'recompile this' or 'change this setting' without explaining how to do it. Please help, I've been unable to connect to wireless in OpenSUSE for 2 weeks now.
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.
All settings are correct as far as i can tell. The wep key works on all my windows boxes. When i have connect automatically enabled it never tries to connect. if I go to edit it it pops kde wallet up i put in credentials. wallet goes away then nothing happens. if i double click connection to my router also nothing happens. I have the wep key in there and i even made it visible to make sure.
Recently i was fixing a permissions error on my home folder. In the process i ran accidentally chmod 777 in the root directory. BIG mistake. Now i cant run sudo, or start network manager. I am currently on vacation and made a bootable version ov ubuntu on my flash drive, but i wouldn't boot. I think it is because i chmod'ed the grub folder (with is in the root) I have a boot CD a home, but is there anyway to fix it beforehand?
These problems just started the last couple of days but I have been using Lucid 10.04 for a month now. My wireless Signal varies in strength wildly. I sitting at home, not 20 feet from my router. I never had these problems before Ubuntu Lucid Lynx 10.04. I am running both Network Manager and Wicd.
Errors: 1. Wicd states "Wrong Password" which is not true. 2. Dropping off-line for no reason, sometimes 3 or 4 times a minute and sometimes it works fine for hours. 3. Firefox 3.6.3 Automatically Checking "Work Offline"!?

I have the Proper Wireless Drivers. I have not changed my wireless settings, channel or WPA for 8 months now so I know thats not it.
