Networking :: Wireless Network Times Out - Will Not Restart Without Reboot

Nov 1, 2010

I had been manually starting my wireless network with "sudo iwconfig wlan0 essid "my wireless router id". The network would start and work flawlessly for weeks at a time. I can't ask my wife to find the essid in the terminal and then start wireless manually when I'm not here. She hates and fears the terminal. So I downloaded gnome network manager for a point and click interface on gnome panel.The network would start fine but shut down after anywhere from one to six hours. It would then refuse to restart manually or otherwise. I completely uninstalled network manager and tried wicd instead. The same basic problem is happening. The network will restart if I reboot the computer. My system:

Desktop computer acting as proxy server for the internet. Internet connection is by a dial up modem. This computer uses a wireless pci card connected to a dedicated hub. This is for file sharing via nfs. The OS is ubuntu 9.10. My wife's computer sharing the internet using a proxy to my computer. File sharing via nfs and a wireless card. Also running ubuntu 9.10. This same basic system worked flawlessly under Ubuntu Hardy.My desktop was updated recently with new hardware which created the need to move to Ubuntu Karmic. Some hardware was too new for hardy to deal with.

Networking :: Samba Needs Restart On Reboot?

Jan 20, 2011

running Ubuntu 10.10, generally with no probs. After the upgrade to 10.10, and several updates, I still have a problem. Namely when ever I re-boot, which now more often than I'd like, due to a machine failure. It starts, but accross the network can't "see" tux, pop to root term, and


root@tux:~# stop smbd
smbd stop/waiting
root@tux:~# start smbd
smbd start/running, process 3682

and that fixes it. Whats wrong with the startup script?

Networking :: Wireless On Slack 12.2 Used To Work Now DHCPCD Times Out

Jul 14, 2011

I know questions of the form "wireless not working on <blank>" abound, but here is another! I can't cut and paste since I don't have a connection on the computer I am having trouble with but I will paraphrase the best I can.

lspci output:
0c:00.0 Network controller: Intel ... PRO/wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
lsmod output (relavent line):
cfg80211 33680 3 iwlagn, iwlcore, mac80211

iwconfig shows wlan0 up and running, and iwlist scanning shows the router. I used to be able to just run dhcpcd wlan0 and connect, but now I get a

"timed out waiting for a valid DHCP server response"

Same deal running /etc/rc.d/rc.inet1.conf (which might be the new way Slack connects to things).

Not sure if it's important, but I have a little indicator light on my laptop that tells me if wireless is running. Before I try dhcpcd, the light is on. After it times out, the light goes out and I have to redo everything (ifconfig wlan0 up etc....) in order to get the light back on.

General :: Having To Restart Ubuntu Several Times A Day

Aug 22, 2010

I hope someone can help me. Been using Ubuntu for over a month now (My first foray into Linux) and I love it...BUT I'm having an intermittent problem that seems to be getting worse:Ubuntu will be working fine....then I'll go to open a program (like Chromium or Thunderbird) and it won't open. If I already have Chromium open, it might become unresponsive. If I'm downloading something, it will start acting weird (Like last night- I was downloading c.600MB file and Ubuntu went into dysfunctional mode- and said it was downloading a 2006453 GB file!)

Also, when it goes into dysfunctional mode, any dialogue boxes that come up (like the shut-down confirmation box) will be blank- just pure white- with no text or buttons visible.I can't even run any terminal commands when this happens, to try and diagnose the problem, because either terminal won't open, or if it does, it will be blank like the dialogue boxes- i.e. the purple background will just be replaced by pure white, with no cursor or text).I'll then restart the computer when these things happen, and then I'll get the "The disk for /tmp is not ready yet or not present" and have to press "f: to fix it- then it will boot up and work fine- sometimes for the rest of the day...sometimes for 5 minutes.

Since I don't see anyone else complaining about such behavior, I assume the problem is with my 'puter or my installation? If anyone has any ideas, please help. I really don't want to have to switch to a different distro- as I love Ubuntu///and I don't want to have to reinstall - as I have it configured the way I want it and plus it's on a partition (Still need to keep Win-D'ohs around just for when I want to use Magicjack)This is starting to happen several times a day...HELP...can't. Go. On like this![My 'puter's specs: Compaq Presario SR2170NX P4 3.0Ghz 1G Ram 150GB HD -all I usually do these days is email and the web]

Ubuntu :: Restart Several Times The Bios And Boot Loader?

Jun 17, 2011

First off, i have ran 10.10 for the past 6 months without any problems. Then last week i decided to try 11.04. I installed using Wubi. Now the problem is the computer only freezes when I am using a web browser (firefox). it completely freezes where I can do nothing, so I will kill it with the power button. When i try to restart, not even the bios will boot up, just a blank screen with the num/caps lock key flashing.

But after trying to restart several times the bios and boot loader will eventually come up and will start up normally until the same thing happens. I decided to reinstall using wubi so when i tried to boot itno windows, the windows partition was corrupted. I fully restored windows and installed 11.04 with wubi again only to have the same freezing problems.

I will be trying 10.10 again and see if it just a 11.04 issue, but thought this problem should be out there if anyone else has a similar experience

Ubuntu Networking :: Wireless Connection - Takes Upward Of 10 Minutes And Over 20 Times Of Me Clicking 'Connect'

Jun 20, 2011

I have been having trouble with Ubuntu 11.04 when connecting to the Internet via Wireless Networking. It will connect, and has good speed once it connects, however it takes upward of 10 minutes and over 20 times of me clicking 'Connect'.

Is there a way to connect to a wireless network quicker? My network is unsecured and without a keyring. It is not only slow connecting to my network, but the network of other's.

Ubuntu Networking :: Wireless Networking Quit After Reboot?

Feb 27, 2010

I've had my wireless networking (on an Acer Aspire laptop) working perfectly well for at least six months.Now, quite suddenly, after a reboot I get the message from wicd, "No wireless networks found". I probably was running a week or so before that without needing a reboot. Windows wireless is fine (I'm using it to send this post).In addition, my sound stopped working and I see a fleeting message to the effect that the sound system is reverting from analog to digital.I'm running Kubuntu 9.10. My guess is that something in a recent round of updates knocked me out of the box. How can I proceed to set things aright?

Ubuntu Networking :: Wireless Works Until Restart To Complete Update / Fix It?

Oct 22, 2010

Here is my problem: I am using ubuntu 10.10 64 bit installed on a HP tx2 1274nr laptop. I can get my wireless to work on both the Broadcom B43 wireless driver and the Broadcom STA wireless driver. Though only one can be active at a time.

My problem lies in I can activate either driver until I reboot the laptop. then it becomes inactive.

Is there a fix for this problem. I would like to have my wireless active after restarting.

Ubuntu :: How To Restart Network Adapter (not Service) Without Restart?

Mar 13, 2010

I have a suspend problem in my laptop. Sometimes, when resuming from suspend, the network adapter is down (that is, the network does not work and the light of the network adapter is off). Restarting the network service doesn't work, because I think that the system forgot about the hardware, and probably the driver should be reloaded.Does anyone knows how to do that?(ps. /etc/init.d/networking restart does not work, because the hardware driver is not being recognized anymore).

Ubuntu Networking :: Need To Reinstall Wireless Driver After Reboot

May 28, 2010

I've been searching forums like for 2 days, but couldn't find any similar problem.
First of all im running Ubuntu 10.04 desktop version on my netbook Acer aspire one (AOD150)
Every time i turn off my netbook and after turn it on, in "Hardware drivers" it says that driver for wifi is not in use, also button for switching on/off wifi is not working.
So everytime i start up i have to go into "Hardware drivers", remove driver for wifi, and then activate it again. And everything is working gr8 after. Its just too annoying to do it everytime.

Ubuntu Networking :: Wireless Down On Reboot - No Hardware Present

Oct 1, 2010

i installed linux on this laptop around 2 years ago (hp g6000 laptop) with internal wireless card and was unable to get the internal wireless card to work under ubuntu. so i purchased a linux supported usb wifi stick, which worked perfectly (connected automatically on boot) each time. however, i moved house recently and lost this usb wifi stick. i am currently using a ethernet connection to my hub and have updated ubuntu to the current version. all software is also up to date. since i lost my old wifi stick, i have used this connection, however, yesterday when i was on videos, all of a sudden (without me having done anything {intentionally anyway}) i see the wireless connection graphic at the top right of the screen! both green dots lit and the connection was live! so i disconnected the ethernet and used the wifi all night without a hitch.

i was extremely happy with what had happened and could not work out why it had decided to work (having not been aware to doing anything, except sit and watch a videos video). so i shut down, go to bed, go to work the next day and come home looking forward to browsing the web from my sofa, and guess what, no internet connection once i logged in! i just think 'if it worked last night, it can work now'. i have ndiswrapper and i have the .inf driver file for the internal card installed in ndiswrapper. i have opened that tonight and it looks okay - except it says 'hardware present: no'. i do not understand what has happened at all. (also there is a wifi 'on off' switch on the front of the laptop, with an orange led but neither position makes any difference to the card working or not and it hasnt changed positions since i moved house (to the best of my knowledge anyway).

Ubuntu Networking :: Wireless Fails After Reboot / Suspend

Dec 30, 2010

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.

Ubuntu Networking :: Wireless Randomly Disconnects - Only Works Again After Reboot

Jul 3, 2010

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.

I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.
