Ubuntu Networking :: Wireless Not Working In-case Of Force Shutdown?
Sep 27, 2010
i'm using Ubuntu in my office. I have to report two issues with network connectivity.1. Wireless doesn't work if come back after suspend/hibernate the computer. The work around I follow is,a. Turnoff the wifi and restart the computer. (It won't shutdown. have to do force using the power button)b. Reinstall the network-manager_0.8-0ubuntu3_amd64.deb and network-manager-gnome_0.8-0ubuntu3_amd64.debc. Restart the computer (Again it won't shutdown. Need force.)d. Now wifi will detect the networks and shutdown works fine hereafter.2. Sometimes the wired gets disconnect frequently (thrice in 2minutes). Physical connectivity is good and working well in Windows.

I've installed xUbuntu on a machine I will be using as a file server. Everything is fine except one thing. If the server suffers an improper shutdown such as a loss of power the next time the machine boots it gets to the GRUB2 boot menu and then waits for a keyboard input.As this machine runs headless with nothing connected other than a network cable and power lead and is tucked away under the stairs it's quite an inconvienience to go to the machine and plug in a keyboard so I can press enter.Is there some way I could force the machine to boot as normal without stopping at the menu ?

Everytime I try to install opensuse it locks up at the very finish, forcing me to force shutdown. Then when I try to boot up, it loads a horribly misconfigured view of another linux install. Anyone know what is going on? I posted here alsi: Opensuse install problems - linux-free-bsd-general-discussion - Linux-Free-BSD

I installed office 2000 CD using wine, I did this on Ubuntu net-book remix on a NC10 using a networked CD drive. So the installation went okay, I then came to using the software, word opened and promoted me for my product key, which I entered correctly the window disappeared for a second then repaired, I entered the key again but then this caused the whole program to shut down, I have tried repairing it , reinstalling it all apart from uninstalling and reinstalling it. Which I have tried and subsequently failed
Right I got it to work, so for any looking for the solutions simply go to /home/(username)/.wine/system.reg and change the user name and the organisation either delete it or enter something, I entered my user name but I left the organisation blank but I left the quote marks that were there. Save it and the product code thingy should not appear again.

Two or three times on a daily basis it just freezes and I do not know why. For example, I am doing some minor coding, surfing the web and just some regular stuff and suddenly, out of nowhere, it just freezes. I cannot force reboot, cannot shutdown, cannot run, cannot enter terminal, nothing. Totally helpless. Only physical reboot do the work. Never had this issue before.

If I issue a shutdown -rF now, it will force e2fsck's on all the volumes when it reboots. But once the checks automatically finish, does it restart normally? I want to run e2fsck's on all my volumes, but dont want to stay the probably 5 hours it will run, so hoping someone knows for sure what happens.

I have strange behaviour on my portable computer Asus UX30. I'm using latest Ubuntu 10.10 release. The main problem, and the most annoying, is a system freeze on shutdown, suspend, hibernate or even restart. For a week I'm trying to find a solution on the web, but no result. From what I noticed, computer freezes when a wireless card is turned off or on. Here are some basic info from wireless card:
Code:
sudo lshw -class Network
*-network

product: RT3091 Wireless 802.11n 1T/2R PCIe
vendor: RaLink

Kernel 2.6, Slackware 12.0
mkisofs 2.01
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.
Quote:
-iso-level level
.........................
With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_).
...........................
However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:
root@darkstar:~# mkisofs -iso-level 1 -o image John Smith.txt

I have one desktop PC I'd like to use as a jukebox. It's installed in the basement as a black box, with only SSH access, and it has got a minimal CentOS 5.3 install with MPD and NCMPC. It's connected to the hi-fi in the basement, so I can stream music to it when I'm downstairs. Since I didn't want to use cables everywhere, I bought a PCI wireless card, with a RT2561 chip.
Until recently this card worked OK with Linux. Recent kernel version even have out-of-the-box support for it, except of course you still have to download the firmware from the Ralinktech website.
I gave the thing a static IP configuration by editing /etc/sysconfig/network-scripts/ifcfg-wlan0, interface went up fine, I can ping the machine and SSH into it OK. Now the only problem is, when I do a shutdown -h now, the machine "hangs" while trying to bring wlan0 down. (In case you wonder: I temporarily attached a monitor to it, since wanting to know what goes on while shutting down in an SSH session is a chicken-and-egg situation :)). I actually have to hard-reboot it (by pressing RESET).

I ran "yum update" on 03-06-2009 and it updated my samba version from
3.2.8-0.26.fc10.x86_64
to
3.2.11-0.30.fc10.x86_64
My network shares then became read only!After some digging it turns out my system is not working because of Samba bug 6291, the "force user" option is no longer working.
Ideally I would run another "yum update" and that would fix the problem. Apparently the bug has been fixed in Samba 3.4.0pre2 - when can when we expect that to be released and included when I do a "yum update"?
Alternatively how do I get back to version 3.2.8-0.26.fc10.x86_64 ?

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.

I have a device that is only accessible using wireless. By default it starts an ad-hoc wireless I can connect to. The problem is there is no internet access on the ad-hoc. So I'm connecting it to my router using the commands (its a gnu/linux):
iwconfig ath0 mode managed essid "ESSID"
ifconfig ath0 192.168.1.25 netmask 255.255.255.0 up
route add default gw 192.168.1.1
I want to add it to start up script but I don't want to get locked out of the device forever if something happens to the router (its really old). Is there any way to check if the connection failed and create an ad-hoc instead if it failed?

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.

Bought this USB wireless NIC but didn't realize v3 was on the market and only for about the past month or so..Cannot use NDISWRAPPER for intended specific purpose.A Google search reveals at least one unrequited SOL user in the Ubuntu forums..I can't even find out what chipset is in this thing, doesn't seem to be published anywhere (is there a utility that interrogates USB NICs?)So, looking for suggestions before I give up on this device, BTW here is the typical reports, people might notice that the VendorID/ProdID doesn't return much info on the Internet.Is there a way to force try the driver for v2 of this NIC? I'm not familiar with a procedure that doesn't require some level of device recognition.

I used Gefoce9400GT , 190.53 nvidia driver, configuring Mulitiple X screen both CRT and TV, work fine if CRT and TV connected to card, but I hope foce TV-out output signal, means that if not connected to TV, the SVIDEO can output signal. Because the line too far, cannot detect TV connection, so I think foce output TV-out signal. I used Option "ConnectedMonitor" "CRT, TV". Can force found 2 display device, have 2 screen ok, but not display at TV if not connected TV. I do not understand why the TV has been forced output signal does not display images, they can be connected to the TV show?

In another thread I shared how my system occasionally freezes. I found a solution in which I forced the drive connected to sata port 1 (ata1) to run at 1.5 Gbps and let the second drive connected to sata port 2 run at 3.0 Gbps. I have multiple systems on this machine. When I boot into Slackware 12.2 with the 2.6.27.58 kernel.
I see this in dmesg:
ata1: FORCE: PHY spd limit set to 1.5Gbps
ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xe000 irq 23
ata1: SATA link up 1.5 Gbps (SStatus 123 SControl 300)
Looks okay. When I boot into Slackware 13.1 I see this in dmesg:
ata1: FORCE: PHY spd limit set to 1.5Gbps
ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xe000 irq 23
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
Further, when I boot into 13.1 the freezing problems return. Therefore I suspect the drive is running at 3.0 Gbps.
1. Why isn't libata.force working?
2. How can I know what speed the drive is running?

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.

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:
Code:
