Ubuntu Networking :: Says Wireless Is Connected But Cannot Find Server
Mar 1, 2011
Just installed ubuntu 10.04 on my Dell inspiron 1525 laptop. Everything got installed right, and I elected to select the sta driver rather than the B43 driver. After restarting, the b43 option disappeared. The wireless said it connected, but when i went to firefox it wouldn't load and said server not found. My wireless card is a bcm4312. Any ideas as to why this is not working?
School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.
So here is what works:
1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.
2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).
3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.
What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:
Code:
The system is going down for halt NOW!
acpid: exiting init: cron main process (1011) killed by TERM signal. init: tty1 main process (1365) killed by TERM signal.
[code]...
If I try ctrl-alt-del at this stage, it says:
"init: rc main process (3030) killed by TERM signal"
"Checking for running unattended-upgrades: "
And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.
We have near about 90 RHEL servers. I want to find out which servers are connected to SAN [HP-SAN] storage???? Because many of them are having local hard disks.
I have a device (not a pc) connected to my pc via ethernet, it dose not show up in networks, I was hoping there was a way of scanning to detect for it, is there a way of seeing content of it is basically what I'm asking?
I just installed Ubuntu 10.04, 32 bit, yesterday on my Dell Latitude 6500E and I am new to Linux. I can't find my HP LaserJet 3015 on my home network, even though it is connected to a new Windows 7, 64 bit PC thru USB. The other Windows PCs find it fine, and all 4 PCs can see each other on the network. So, I installed the HP software (http://hplipopensource.com/hplip-web...all/index.html) and that went smoothly, but the printer is still invisible. I also added Samba and that works great like everything else. I plugged the printer in directly to my Ubuntu laptop's USB port and it printed instantly. Now, if I could just print to the LaserJet on the network. Anybody got this one figured out? Does Wine provide a way around this?
I desire to access a WD Netcenter network drive from Ubuntu 10.10 using NFS mounts.Several on line helps show how if you know the IP address of the drive. How can I discover the IP address of the drive. My Windows network is using DHCP, though I understand that the drive uses a static address. I know the MAC address of the drive. As a user (but not an administrator), I have much Unix experience.
I need a bash script to run ARPON for the connected network device, eth1 or eth2. (ethernet or wireless)
Arpon has an option (-o) to select the network automatically, but it only works for ethernet, hence i need this script. I've also tried running arpon for ethernet and wireless at the same time, but the arpon process running the inactive device will consume all of my CPU.
So, basically i need a script to find which device is connected, eth1 or eth2 and then to run arpon -d -i <device connected> (or something like that).
Is there an easy way to do this? code...
I've searched everywhere how to find the connected device via bash, but i couldn't find anything.
My mom has ubuntu 8.04.2, and it does not stay connected on the wireless usb cards. I tried 2 different ones, 1 azio and 1 is something else. But both get connected, but they die out after awhile. I am at work typing this, so I will probably try to move my router up higher or something, but it is weird it cuts out like every 15-30 minutes, and it starts at like 4 bars.
She is running it out of a live DVD( I Know, you shouldnt use a DVD as your main OS) but she only needs the internet, and uses google docs to save stuff or a USB stick. Anyone know what might be the cause of this disturbance in the connection. It is a cable connection, and the main modem is in my room, and we got a netgear router( maybe the problem?). I tried the same exact system/live dvd environment at my work place and it held connection pretty good, but I believe it did disconnect a few times as well.
Im using a laptop with a wireless card inside it is a Realtek RTL8187B network adaptor. I go to wireless connections in the toolbar at the top of the screen and click on my internet modem and it says its connected. So I go to firefox and it brings up google. I try and do a search and it says something and at the bottom of the page it displays a button that says "Try Again". Im booting ubuntu from the cd drive so its not installed on my computer what should i be trying?
I have an old GX 159 Dell Desktop I tried to install Ubuntu 10.10 on it and it worked like charm the problem is when I connect my Alfa 1 wireless adapter and connect to the network it won't let me connect to the internet. Well I have been succeeded to connect to the weather center, but I can't update or open the Internet even if I have been able to open Hotmail.com after 2 minutes it won't open anything after that
Note: I didn't install the driver for adapter and I don't know how to do it because I tried before and I failed adding I used it on more than one distro. By the way it works perfect on Windows?
I had the wrong WPA password.[/blush] It appeared to me that it was connected OK at the physical/datalink level but apparently that was not the case.I've set up an old PC with the latest Ubuntu desktop and am trying to set up wireless networking with a TP-Link TL-WN722N. It only came with Windows drivers but from a thread elsewhere I got it to where it finds my router and connects with the password. However, it doesn't pick up its IP details. The router is working fine wirelessly on my phone and wirefully on my other PC.
I've edited /etc/network/interfaces with "auto wlan0" and "iface wlan0 inet dhcp" but after restart the wlan0 interface has no IP details. Originally the interface had IPv6 details but I cleared that with ifconfig. Under the Network Connections Wireless tab it has "Auto" followed by the name of my wireless connection so it appears to have connected OK. Now when I click Edit for that connection nmame, the IPv6 tab says Ignore and IPv4 says Automatic (DHCP) but Addresses is greyed out and the other fields are all empty.
i am running backtrack3 with vmware station in window 7. but the problem is when i enter iwconfig it does not show my alpha awus036h. it does not detect my alpha card. if anybody can help me regarding the same??? i have already tried to set it in vmware station menu bar vm=>removable devices to get my wireless but it showing a usb device connected... not showing my wireless..
I have Hughesnet (which sucks by the way, don't get it, I hate contracts). The FAP states that i can only download 375MB or it shuts me down, however, from 2 to 7 AM you can download all you want. so naturally i use a download scheduler. The only problem is that at night when i shut my laptop lid it disconnects from my router.
I've installed Ubuntu 10.04 32 bit version(dual OS) on my 64 bit Pentium core2 duo 2.2GHz processor. Everything seems to be working fine except it's not getting connected to wireless network, although it's detected the network .It was working fine(got connected to wireless network) when I had installed the same OS via virtual machine.
The wireless usb adapter connects to my network, and the router is running on mixed mode, except that I cannot seem to get wireless 'n' connection speeds. Both are capable of wireless n. I check the connection info and it is always 54 Mbps. I have set the router wireless on N-only and I lose my connection.Is the standard driver for this usb adapter in Ubuntu 10.4 unable to utilize 'n' speeds?
I upgraded to 10.10 the day it came out, and haven't had any problems with internet stuff. My wireless card works without any proprietary drivers. Last night, the computer stopped connecting to the internet. I am still connected to my wifi network, but I can't do anything online. I had assumed that my internet connection was just down in general, and tried resetting the computer, shutting down the computer and then turning it on again, and rebooting the modem, but then my Xbox connected, and my laptop running 10.04 connected, so I'm confused as to what is going in. Any ideas?
I am running Ubuntu 10.10 on a Dell Dimension 4700 desktop computer. I just upgraded to 10.10 from the previous version after getting my D-Link wireless adapter back after loaning it out. My internet now won't stay connected. I can connect when I firstrn on the computer, with after 2-5 minutes it drops the connection and gives me the "Wireless Network Authentication Required" prompt. It won't connect again without unplugging the adapter and plugging it back in.I borrowed a Belkin wirelss adapter to try it, and it does the exact same thing. PLEASE can someone help me, I really need the internet up on the computer(Also, when I first got the adapter-- while running the old version of Ubuntu-- it would not recognize or connect at all and I spent 4 hours messing with drivers and settings to get it to work, which it did flawlessly. Until I upgraded.)
I've had ubuntu installed for a bit now and I want to start using it as my main OS, but the wireless internet will not stay connected. It will connect at first and if I'm lucky it will stay connected for around 15 - 20 minutes. I have a toshiba laptop with an AtherosAR5007EG internal network card.
I have installed ubuntu 10.04 and STA wireless driver. I am using a wimax modem, the wireless is connected (have IP addresses) but I do not have access to the internet.I also have installed a windows XP as a guest OS (ubuntu is the host) on vmware. By using a bridged network connection, I am able to access internet. So I guess the problem is related to the ubuntu wireless driver.
I installed Fedora 15 today and after a few very long hours finally got the broadcom driver to work and my laptop is now connected to my router. Yay! But now when I try going to a website in firefox it says server not found. I can ping anything inside my network but when I try to ping outside the network, for example google, it says ping: unknown host google.com. So I thought it might be a DNS problem but the network settings point to the router for DNS so I'm not sure what else could be wrong. All of the other settings look correct.
I have a WET54g bridge that I am trying to get connected to a wireless network that only allows DHCP. The idea behind it is that I would like to connect the Cat6 out of the bridge to a switch allowing multiple wired computers to connect to the wireless network. The bridge will easily connect to the network once I put the WEP key in, however, there is a kink after that. When I connect the Cat6 to my computer and request an IP for that computer, it self assigns. This tells me that it is not talking to the wireless network through the bridge.
I can not find which IP address the bridge was assigned so that I can talk to it. The sub net is 255.255.240.0 which leaves quite a few possibilities. I know that the bridge is, however talking to the wireless network because the light is steady on the front of it which indicates just that. One other thing to stack on is that I know that there is a "splash page" which comes up when any computer connects. You click on the agreement and then you are allowed onto the network. How can I get my computer to talk through the bridge to the wireless network?
I'm new to Ubuntu and i set up my wireless myself and I think I may have put in wrong settings. I looked through the forum and found these commands to put in the terminal from other posts. Could someone please see if they can fathom what I've done wrong. I have an wG111v2 netgear usb which works fine in windows but is very sluggish on Ubuntu. It worked for a while but since i have deleted and reinstalled my wireless numerous times I now can't get iternet at all. I have Ubuntu 9.10 on my machine which I duel boot with winXP.

as the titles states my wireless is dropping out but the networks manager is still saying i have a connection. the only way i have been able to be on the network every minute or so i have to manauly disconnect and reconnect to my wifi. under my windows 7 and vista installs the wireless card works fine now my card is a dlink dwa-547 and it uses the arthores chipset, it is encprtyed wifi, wpa2 aes on a n/g based network
When I turn on the computer, it connects to wireless automatically. That's good. But it doesn't stay connected very long. Especially if I turn on a p2p program or make a call through messenger. Then I get disconnected suddenly and if I want to connect again it doesn't work anymore. Network - You are now disconnected and that's it. Every time it happens I restart the system. I use an Acer Aspire 5738z laptop.
Is there away to view wireless access points without being connected. I am having trouble getting connected to my wireless DSL modem. I have no problems connecting with Windows Vista. Just can not get Ubuntu 9.10 to connect. iwconfig says no associated with access point. I can connect with ethernet cable.
Ubuntu 9.10 working great. Installed Orange 515m as per fix shared on this and other forums; however while it works great at home, it will only 'connect' once at work - on subsequent attempts it connects, but browser etc behave as though they cannot find the modem and I cannot make further connections via gmail and Firefox. I had just made the swap from Win 7 to Ubuntu 9.10 for work as well as home, but I cannot be in the position of being unable to access my emails and so swapped my hard drive back to Win 7 drive today
I just upgraded to 10.04 from 9.10 and I ran into few issues.
Laptop - Dell Vostro 1520 OS - Ubuntu 10.04 64 bit
Issue - My wifi connects to the network properly and shows connection established. But I am not able to browse. I tried ping and I didn't got any response. But I was able to get response when I use ethernet (wired connection) and I am able to browse. No issues with wifi card as my wifi is working properly from Windows and with the same network. I did a complete update again before posting this and it is yet to be resolved. Here are the output of some commonly asked outputs with wifi enabled and connected:
