Ubuntu Networking :: Wireless Not Working After Suspend?
Jun 17, 2010
After upgrade from Hardy to Lucid, wireless card (Atheros Communications Inc. AR5212 ) was extremely slow and not really functional. I installed the madwifi driver following the instructions from Ubuntu Wiki and wireless works now. But, after suspend Network Manager nor Wicd could scan for any wirelss networks.
I found a workaround: in console, run "dhclient" and, magically, while the scan for Ip address is going on, suddenly also Network Manager starts connecting to my default access point!
I've got a Dell Latitude 131L with Broadcom B4311, running Ubuntu 10.04. Wireless networking generally works just fine, but I lose my connection when the computer is suspended, and I have to reconnect manually from the drop down menu.
I cannot see any wireless networks after waking the computer from suspend. Wireless works fine on boot. I've tried restarting the network service, but I still don't see any available wireless networks.
I recently installed Ubuntu 10.04.1 LTS and have it set to dual-boot with windows 7 on my gateway tablet PC. Since installing, sometimes when I suspend or reboot, my wireless does not work. To be more clear - it is working fine, then I either suspend/reboot, then I come back and no wireless networks show up at all. I can still connect with ethernet cable though. I can solve it by rebooting multiple times (usually around 1-5 times) and then it (magically) seems to work again. I have also tried switching from network-manager to wicd, but the problem persists. With both network-manager and wicd, I've tried simulating a reboot for the wireless by using the command 'sudo modprobe -r iwl3945 && sudo modprobe iwl3945' (network-manager) and 'sudo /etc/init.d/wicd restart' (wicd), but these do not seem to work.
I have FC 12 install on a Compaq nx9600 that comes with a Broadcom BMC4306 wireless card. I'm not sure what my kernel is, but I have all of the updates for FC 12.Whenever my laptop resumes from Hibernation/Suspend my Enable Wireless check box in the Network Manager is greyed out and it will not come back till I reboot the computer. Is there any one out there that can help with this problem, as I do not want to disable my Hibernation/Suspend as I tend to forget to turn the laptop off for a few days on end, and this beast sucks a lot of power so it is a drain on my power bill.
I am currently using Ubuntu 10.04 Lucid Lynx. Although it has worked fine for the past couple of weeks, I have recently encountered a problem with my wireless card. It is an Atheros AR928X card on a Toshiba satellite U405D-S2874 model laptop. Recently, I attempted to put the computer into suspend mode for the first time. The computer failed to wake up, and I performed a hard reboot. After this, everything seems to work except for the wireless card. I am now unable to connect to any wireless network with my laptop, and the wireless manager doesn't seem to be working either.
A few months back, my Lenovo IdeaPad Y510 stopped connecting to my wireless network after coming out of Suspend (it had worked fine previously). Wireless networking is simply disabled, and I have to reboot in order to get it back. I tried upgrading my OS from Intrepid all the way to Lucid, but the problem persisted. I also tried changing my 00sleep_module as suggested in this thread, but to no avail.
I want to switch my laptop from XP to Ubuntu, but right now, i cant risk installing it. i dont want to have it partitioned so i can dual boot, so for now i only run the try-it-out mode.Before i consider installing though, i want to see if i can get everything to work ahead of time, that way im not regreting instalation. I have a Compaq Presario V2000 laptop, with 55GB hard drive and 516MB ram. So far, the trial mode is working great, but the wireless will not work. Ive tried to install the driver, but i am unable to do so. I have looked this up, and i have tried many things, and so far, none have worked.I was wondering if it was just part of the trial thing or not, but it is a Broadcom Wireless BCM4318 driver
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
For some reason, i just cannot get my wireless to work in xubuntu. When i click on the network-manager applet, it only has the wired network tab and VPN connections, there are NO wireless networks displayed. I have also tried iwconfig, which returned
lo no wireless extensions. eth0 no wireless extensions. and lspci: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:01.0 PCI bridge: Intel Corporation Mobile 4 Series Chipset PCI Express Graphics Port (rev 07) 00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03)
I can connect to the internet with wired connection. The switch for the device is on but this command "sudo lshw -C network" has the following results:
I have a compaq nc6400 with the intel Pro/Wireless 3945 ABG card. It fails to find any wireless networks.the IWL3945 driver was installed automaticallyBut when searching for networks none are found, even though on any other computer in the house the network is found.According to https://help.ubuntu.com/community/Ha...sIntel#miniPCI
I have just installed openSuse 11.4 KDE 64-bit on a Dell M1330. When I click on my networking panel, it says WLAN interface is unavailable. I've followed the steps in the stickied post and found the WLAN hardware info, a screenshot of which is below:Uploaded with ImageShack.usNext it says to do this - you need to look at the logs, in particular the info in /var/log/boot.msg. To see this, you need YaST => Miscellaneous => System Logs and select boot.msg.In YaST there is no such option for system logs under miscellaneous, so I can't do that. The results of the sudo /usr/sbin/iwlist scan command produce the following:
root's password: lo Interface doesn't support scanning. eth0 Interface doesn't support scanning.
I use KnetworkManager for wireless. Works great except that if laptopgoes into suspend the wireless does not work after resume anymore.NetworkManager log

i just installed Gosalia mad monkey on an old dell d520 latitude but cant get wireless working? i found how to set up my wireless connection butits asking for the default keyring password to unlock?i never set a password for this as it never askedi found this but i still dont understandit states" Typed in all the details, clicked Add and... �Enter password for default keyring to unlock�. Huh? I didn't set that... Tried the root password, tried the user password, none worked. The answer: Gosalia's team remastered Ubuntu with their password locking the keyring. Quite a funny situation.

Just upgraded to the newest version of Ubuntu(unity), and my wireless isn't working. I have the 14e4:4315 Wireless Card so I followed this posts [URL].... And still have no wifi, when I click the icon in the menu bar it says under "Wireless Networks": "wireless is disabled by hardware switch", which ins't true because on my Vostro 1520, there is only one switch and it is in the on position. I've tried 3 versions of ubuntu and none of them work with wifi getting tired of it.
Karmic 2.6.31-22-generic, Asus M3N78-EM, MCE remote with USB/IR dongle, latest Bios, Bios PM enable and set for suspend S3. IT will suspend but I need to depress case power button for it to resume. I want to use my remote control, I also can not get it to resume from Keyboard/mouse (See Note Below). Only suspend and power button work.

I just built my new desktop yesterday, I got elementary Jupiter (built on Ubuntu 10.10) installed and running fine on it, everything works... except for when I tell it to suspend
Upon selecting suspend, the monitor goes black for all of about a second and then comes straight back to the lock screen, pretty damn irritating.
After suspending my computer, the battery icon doesn't work anymore (nothing happens when I put my mouse over it and it doesn't detect wether the computer is plugged in or not). Also, the brightness of the computer doesn't change when I plug/unplug the computer. All of that works fine before i suspend the computer.
Computer is an ACER Power F6, BIOS AMI F6, XPPro installed, C only 80 Gygabites, 2 Gyg RAM, 3000MHZ Pentium4.today I installed 10.0.4 from Canonical 32 bit, all was ok,I followed the suggested dual boot partition and proceedings,which gave XP 44 Gyga and Ubuntu 37 Gyga ,successfully finished install,rebooted and began updating and customizing with great zest as I was really happy about this new version. then I decided to make a break of an hour and thought : 'let's try now the suspend function as i read about it not working properly sometimes'.....so an hour later i tried to revive from suspension,but the pc remains utterly insensitive and black.Tried Del to get into BIOS,F12 to get to boot config,BART PE disk i made for an XP machine in the past, and tried to boot again from the live Ubuntu Cd .....all in vain.I suspect it might be the fact the BIOS was set by me for
1st Floppy 2nd CDROM 3rd HD or PenDrive
as this machine I inherited since a few days dates back to 2006 and has no burner only CD-DVD reader and Floppy is disabled in BIOS.After Ubuntu install the machine stopped for a long time on a black screen with white reading about errors during install,then I reset it and it seemed like a good install anyway.Apart from checking if the HD is still ok,what can I do or try in such a situation?
When I try either one I just get the lock screen where I have to enter my password to return to my session, but the computer never suspends or hibernates.
I have two problems, that I can live with, but they are just annoying for tha afact that I don't know how to fix them.1. My suspend does not work. Hibernation works - after I turn on after the hibernation, screen is blank, I have to move the mouse for the login window to appear. For Suspend, I get to the black screen, but then nothing happens - when I move the mouse or Ctrl+Alt+Backspace, nothing. It is a laptop, if that makes a difference.2. When booting, I get a table of choices - the new kernel, the old kernel, memtests and the long gone windows partition. There is no /etc/grub/menu.lst and I've got no idea how to change this.
EDIT: I found my problem--the box next to headphone box had been unticked, and I feel like a total doof for not having found that during my first two hours of trying to fix this. But I could still use some help figuring out my suspend problems issue--I've heard constantly turning a compy on and off is bad for it somehow.
A couple days ago I attempted to put my computer into suspend mode. When I used regular Ubuntu, this seldom worked. My hard drive would continue spinning, and the computer would not come out of this state until I cut the power and restarted. I thought it might be worth giving a try in Xubuntu, but I ran into the same problems, only this time, the audio would not work when I booted up.
I'm using the 64-bit version of Xubuntu, and this is a relatively fresh install (within the past two weeks) from the version 10.10 DVD, so I haven't had too much time to fudge up the settings yet, so I think it might not be entirely my fault. (: I've checked the hardware, and everything is plugged in and turned on, and I'm getting sound when I boot up Windows.
I may have done something afterwards, though. My first attempt at fixing the problem was to follow these instructions, but I really didn't understand entirely what I was doing. I tried fiddling around with the alsa mixer, but that didn't help me at all, and now it has even disappeared from the upper right-hand corner of my screen--on the toolbar. (If there's a way I could get that back and restore the default settings, [EDIT: I found alsamixer in the applications menu.]
I'd like to have audio working again, but I'm not really sure what's wrong or how to fix it. I'm still reading through Introduction to the Command Line, but as my previous attempt to solve this issue shows, I'm not smart enough to be afraid of entering commands in that I completely do not understand (yet).
In the wake of a spate of posts complaining that wireless is not working in 10.04 here is mine. I'm on a (relatively old) AMD Duron 1.5Ghz, 1.5G memory with a VIA KM-266 motherboard. Wireless worked fine in 9.10. With a fresh install of the new 10.04, the usb wireless adapter is not detected, the tab to add a new wireless connection is grayed out, starting the KNetworkManager (did I got the name right?) does nothing (that is, no application starts), etc.note: if you are wondering how I am accessing the internet, I just fired up the 9.10 live CD, which as you can imagine is not the most practical thing in the world.Here is the info. The commands lsusb and lspci spit the following:
