Ubuntu Networking :: Wireless Connection Lost After Closing Laptop After 9.10 Upgrade
Jan 16, 2010
I have an odd problem in that my wireless connection is okay until I close the laptop. When I open it back up, I'm unable to reconnect. This problem first occurred after upgrading to 9.10. I can reconnect after restarting. I tried several things before breaking down and reinstalling 9.04. After installing 9.04, everything works great. Any suggestions on what is going on before I try upgrading to 9.10 again? I have a Dell D600.
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
I had the Wireless Broadband working. It stopped working after I closed the laptop (suspend). Also the wifi will not connect until reboot. Now the entry for the Wireless Broadband is gone, and the tab for it is greyed out as well.I would be happy to submit this as a bug and assist with the debugging process.
My wife's laptop is Dell Inspiron 6400 running 11.04. Wireless has recently stopped working. Running rfkill list all shows dell-wifi hard blocked no soft blocked no. The fn plus F2 keys toggle status between blocked no and blocked yes, but network manager still can't see network. I've tried removing the Broadcom STA driver - no joy.
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
I used to be able to connect to the net using my laptop {Ubuntu 9.10 on Compaq nx7400.}by means of wi-fi . I do not know what I have done but I lost the facility to connect to the net.I noticed the Network Manager disappeared from the notification area. I manged to put it back. It detects the signal from the router and after entering my password it displays Connection Established but I still cannot access the net and does not load any web pages. I have the same Ubuntu 9.10 Desk on a memory stick, when I use it on the laptop it works fine.
I enclose a screenshot of iwconfig.I did sudo lshw -C network and it shows DISABLED. How do I enable it ? Are there any other info that I should supply and what and how.
I installed a clean installation of ubuntu 10.04 inside Windows 7 and wireless worked normally in the beginning that I downloaded and installed all the updates "I selected without updating Grub".On the first reboot after updates, the wireless icon disappeared from the panel and could not connect to the internet although the settings in the Networking tools were correct.
I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.
It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.
I have fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.
i have a sony vaio VGN-NW150J laptop that was running lucid and had wireless no problem but when i upgraded to maverick i lost all functionality of my intel 5100 agn wireless card. when i run iwconfig this is what i get
Code: iwconfig lo no wireless extensions. eth0 no wireless extensions.
and on bootup it flashes something about no suitable unicode found i can't get a good look at it maverick boot up too fast.
I am new to Ubuntu and I am having problems connecting to the Internet wirelessly. I recently installed Ubuntu into my HP laptop and ever since I did my laptop does not get any wireless networks.
I am looking for information on how to set up my laptop (running ubuntu 10.04) as a wireless access point for other wireless computers, through a mobile broadband usb device. My reason for wanting to do this: i have a mobile broadband verizon usb device for connecting to the internet when a regular wifi connection is not available. however, my wife does not, and it would be nice if she could use her wifi to connect to my laptop wifi and subsequently share my mobile broadband connection. Independently, I have no problems with wireless connectivity using wifi or mobile broadband, I am simply unable to figure out how to configure the two to work together in such a way as to create a wireless access point via my laptop.
I've recently installed ubuntu 10.10 32 bit on an external HDD in order to use it as a portable operating system. An issue I have is when running on my laptop (Samsung R580) the wireless connection drops out however the nm-applet still shows it's connected. If I disconnect and reconnect it keeps asking for the access password. The wireless card on the laptop is the RTL8192E (not SE!). I have used the install on a couple of other machines with different wireless cards and no problems. Linux Kernel version is 2.6.35-22-generic. I have searched around and see that the drivers are in early development. If I tried installing the windows driver via ndiswrapper would this affect the portability of the operating system?
I have not been able to get an internet connection wired or wireless on my laptop. I downloaded the drivers from Acer's website and tried installing them using ndiswrapper. Still no luck.
My laptop has been working fine with ubuntu 10.04, and earlier today it shut down after running out of battery. I came to use itr and discovered that the wifi icon had disappeared from the panel bar, and it won't connect to the wireless networkor via a wired connection.I have had a play around with this, tried ping -c5 google.comresult was:ping: unknown host google.comand ping -c5 4.2.2.1result: onnect:etwork is unreachable.I have other computers connecting to this network and know that it is working fine.
NOTE: My upgrade wasn't smooth. Now everything is extremely slow. However if I boot from the disc to try without installing, the connection problem is still there. There is an exclamation mark on the connection applet, right clicking shows that Enable Wireless is unchecked and unclickable. I've included outputs of common network commands which might prove to be useful.
Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.
I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.
Does anyone know what could be causing a Remote Desktop connection to a 10.04 box to be closing after some period of time? I have three systems all running 10.04 with Remote Desktop enabled. I'm using UltraVNC on Windows 7 to connect to them. If I open a connection and leave it open for a long time (like overnight, for example), when I come back in the morning, I still see the VNC window but as soon as I click on it, it closes. I can immediately open a new connection to the box but it now shows two active connections. At first I was thinking maybe there's an idle timeout value but given that Ubuntu still seems to think that the original connection is active, maybe the problem isn't on the Ubuntu side but on the UltraVNC side?
Everything was working when I was on Ubuntu 9.04 but after I upgraded to 9.10 via their upgrade utility. The upgrade failed at the last point of installation (when it tried to install daemon I think). Nevertheless, after the reboot I was on ubuntu 9.10. But the sound stopped working as well as the mouse trackpad on my laptop. I remember that during the installation when it asked if I wanted to keep the old sound configuration file, I clicked yes. So is there I way to fix/reinstall the sound driver and the tackpad? In the sound hardware setting window, no device is listed. I'm pretty sure that my hardwares work on ubuntu 9.10 as the sound and trackpad work fine using the ubuntu 9.10 live CD.

Ok, so I upgraded my acer aspire one to the new Ubuntu 10, and at first everything was working fine, except the audio. Now, for some reason, my wireless and ethernet ports have died. I can't get online by either method. I can do ifconfig <device> up and it will show up if i do iwconfig or ifconfig, but the wireless isn't associated with the AP. Currently I'm trying to load some drivers for my atheros card, and we'll see how that works outReally I was wondering, how come the modules don't load at boot time, and how can I fix this? I've been a Linux user for quite sometime, however I've been more of end user
Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.
After having updated unconditionally all packages in Kde-desktop-factory-repository to get the latest version 4.4.4, I can no longer connect to the Internet through Knetworkmanager. I receive the the following message from a pop-up window when clicking on the Knetworkmanager icon
Code: KNetworkManager cannot start because the installation is misconfigured.System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution.KNetworkManager will not start automatically in future.I tried opening Knetworkmanager in a terminal as root user through 'su' but received the following message:
Code:# knetworkmanager knetworkmanager(2331): KUniqueApplication: Cannot find the D-Bus session server:"Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
New and ignorant here. I got a new System 76 netbook, love it, went to upgrade Ubuntu and since, have not been able to get wireless to work. Wireless light is off, no switches work to activate. Unit has no CD drive, can't get on internet without connection. Not sure this is the correct forum.
I'm relatively new to Linux. My netbook ran updates yesterday for Ubuntu and now I am unable to reconnect to wireless network connection. I am using WPA2 encrypted security. I am able to connect via wired LAN. Also, when I went to connect using USB mobile connection, I get an error "unable to mount location". I get the same error if I try to connect my external CD drive. I am using Ubuntu 8.04 with Gnome desktop (2.22.3) on a Dell Mini 9.My wireless device is using Broadcom STA Wireless driver for an 802.11 wireless card.
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.
I just installed ubuntu 10.04 on my laptop. everything was working fine until i installed firestarter. i didnt like it and uninstalled it. when i did that i lost my wireless signal icon at the top of the screen, firefox starts up in offline mode, and limewire says that network connection is lost. i just want it back the way it was before installing firestarter. please help, i dont want to reinstall ubuntu if i dont have to.

My latop has suddenly lost it's ability to see my main computer. I have changed nothing other than updates and a few non-network related program installs. The laptop is an HP Pavillion DM3 running 10.10 and the PC is a Dell XPS400 running 10.04.01. I have both Samba and folder sharing in use. I have checked all the permissions etc on the shares and in Samba and everything is as it was and should be. So I am confused. How do I get it back and why did it go away?
I've got an Asus G50 and when I try to connect it wirelessly there's no connection setup. I try to setup one and I get nothing. It will connect wired though.So how do I get it to see my wireless router?
