Ubuntu Networking :: No Network After Suspend Mode?
Feb 10, 2011
I have never had a working suspend. But ... every year or so I try it DOH!!! to see if the updates have solved itI used suspend mode today, and when I woke the system up , all seemed fine untill I tried to browse the internet.It told me I was offline. no ammount of clicking "go online" would work.So, then I noticed the network connection was broken.I did a few things to get connected, and I want you all to tell me what I need to put back again ! IPV4 and IPV6, I unclicked the box to require this for connection to complete.Somewhere else, there was a list of servers to ignore. I removed them all. (I think there werre 3) one was localhost another was similar, and the third was a number.I just want to know what these should be set at, because just because it works - doesn't make it right

After fixing an issue with sleep mode, my WiFi is automatically disabled on my Ubuntu installation on boot while the switch is on. For some reason, it seems that Ubuntu has an issue communicating with my BIOS. As a fix to this problem: I disabled the C4 sleep state. My Ubuntu installation now boots up fine but the LED on the WiFi indicator glows orange, indicating that it's off; while in Windows it glows blue, indicating that it's on.

I just performed a clean install on a desktop (older IBEX model) that is connected directly to a Cicso router; this is a DSL service. I configured the Network during the install, and all went well, the installation script downloaded many software modules, I was able to set up my mail accounts, etc. Now, if I suspend this machine and log back on I notice that I am no longer connected to the Network. Clicking on the Network icon brings up the configuration pane, and the original network appears to be there, but I cannot figure out how to make it reconnect without rebooting.

Is there a way to check what caused Ubuntu to wake from suspend mode?
Ubuntu 10.10 on a desktop.
Have tried disabling all BIOS wake events (and WOL).
Have ensured mouse doesn't move.
Need a way to know what caused it to wake. Happens 90% of the time, usually 3 seconds after it suspends.

Disclaimer: I have very little linux desktop experience...I've only used command line stuff for work in my previous life. I am joyfully coming off of a long addiction to MS but am having a bit of a hard time adjusting.
ISSUE: I can't seem to figure out how to turn off suspend mode. I have turned every setting I could find in the power management to "do nothing" and I have turned off all of my power mgmt options in the system bios. A "friend" suggested I remove HAL...which caused me to lose my secondary internal HD and all of my usb devices...and the issue persisted. Every 20 minutes of no action the screen blanks and my monitor goes into standby mode which is making watching movies in bed a less than relaxing experience.
Some background that may or may not be useful: I installed kubunutu 10.04 (2.6.32-28-generic) from cd on a fresh HD. Initially I had issues with the wireless network and alsa/pulse sound. I worked through those through much trial and error but the suspend issue persists. I've uninstalled and re-installed lots of packages I probably shouldn't have been messing with and would really like to avoid a reinstall as this seems to be the final fix I need to get things running the way I want them.

Title says it all. I close my laptop lid. It goes into suspend mode. I open it up again, the computer powers up... and I see a black blank screen. No key combinations seems to bring anything back.

I have ubuntu 10.04 installed. I have a problem when my usb IR receiver is connected, than suspend mode isn't working. System will jump into black screen and that's all. Only hard reset works. I tested this problem also on ubuntu 9.04 and situation is the same.Is there any way how to force suspend mode without "looking" on this device? Do you need any log file to trace reason of this problem ?

I was thinking, is it possible to keep the internet connection on while in suspend mode? i mean that you could maybe use download something, or use something that doesnt use hdd?

Is anyone else having trouble with waking up from suspend mode? After bringing the computer (Dell Studio 1555) back from suspend mode, GNOME moves very slowly. Cursor is unresponsive for significant amounts of time - any open windows do not respond to selection... Effects don't usually go away until a reboot is performed. This evening, one such restart resulted in a crash, where the shutdown process locked at the attempt to shut down the mouse/pointer module..

In Windows I can get my computer to resume from sleep mode by pressing any key on the keyboard. My keyboard is a Logitech G15 (USB).
How can I get this functionality in Ubuntu?

Just curious if this is possible. What I want to do is setup a rsync job to backup my laptop to my personal file server(same LAN), but I want it do do this at 3AM while I'm sleeping. However I always close my laptop lid when I'm done using it which puts the laptop into suspend mode since that's how I configured my power options in gnome. Since I don't want to leave my laptop powered up all the time, I was wondering if it is possible to have a cron job scheduled that will wake the laptop up(out of suspend mode) and run my script/backup job, all without opening the lid of the laptop, and then put it back into suspend mode when it's done. Is this possible, and is it as easy as scheduling a cron job or is there some other scripting/configuration/trickery that I need to do to accomplish this?
Also, my laptop's BIOS has the option to power on at a scheduled time if needed, but I'm not sure if that would work with it being suspended(hibernation is not an option since my entire HD is encrypted with LUKS and I would have to be present to enter the password to boot the system.).

I have a HP Pavillion DV7 laptop running Ubuntu 10.04, and I am having some problems with Ubuntu handling a network connection. Every so often, I leave my computer in locked mode overnight to download something. But, when I do this, the network just deactivates early on [there is a symbol of a blank wireless symbol with a red "?" by it]. Both the wireless and wired network connections are deactivated, and I am using a wired connection. This also sometimes happens in suspend mode, too, but less often. I have to restart my computer before it will connect again, as logging out and back in again does not suffice.

I've tried ubuntu, kubuntu, fedora and linux mint. all 64 bit versions. I've also tried to suspend through applications like acpitool. But nothing works. When I click on Suspend, the screen goes blank but the computer is still running. The wireless network adaptor gets disabled for a second and then comes back on. All I have to do is press a key and I get the unlock screen prompt. Basically, suspend works like 'Lock Screen'. I have a HP Pavillion laptop. Core 2 Duo @ 2 GHz and 4 GB RAM.

My computer have ATI X600 graphics card installed, and I installed CentOS5.3.
Every time I suspend my computer and then resume it, it seem the graphics card can't resume and the monitor says 'no signal', but the system still responses, I can use keyboard.
Is there any configuration I can't do to make it resume normally? I've searched a lot in Google but can't find out any one else run into the same problem.

I made a big mistake. While logged in as root i deleted the /bin directory by mistake. I cannot boot up now...I tried to re-install with the upgrade option...Did it partly but it does not go to the login. I tried a rescue operation and have gone into /mnt/sysimage...However I do not know how to copy my data files over the network to another computer. If I could do that it would be great...I can then backup my file and reinstall.
However I do not know how to setup the network in rescue mode..
Agter going into the network option ...It gave 2 places where I could enter the values ipv4 .and ipv6...I tried entering the old IP address in the first oprtion ........./....Its prompting for some entry to be put after the /. I think its a 3 digit input. Not sure what has to be done.with namesserver and default gateway....I have a small dlink hub and normally (when the system was running) I just needed to go into network manager and enter the machine ipaddress, subnet mask 255.255.255.0 and some value for the default gateway which was not really there....It worked, i could remote connect with another computer in my LAN. How do i enter the 255.255.255.0 in rescue mode?

I ordered this USB 802.11n dongle for about $10 and am having problems.I found a firmware related bug (Bug #595455) that keeps it from working out of the box and got around that. I put the right firmware file in the right place and CAN CONNECT TO B or G Access Points.hen I put my AP in N-Only mode, I can see the network, but cannot associate. With the AP in mixed mode I can Associate using G.The most interesting thing I found was something that had very
few google hits (like 4). In the dmesg output after associating I see the message:
Successfully associated, ht not enabled(0, 1)The most interesting thing about this is the (0, 1) at the end.I don't know what that means but it seems like a clue as to what the problem is.This device uses the realtek chipset 8191S, there are conflicting reports on this, but all the reported possibilities seem to use the same driver from realtek (rtl8712_8188_8191_8192SU_usb_linux_v2.6.0006.2010 0625).Here is some random info:
Dmesg output:
[85082.620027] usb 1-3: new high speed USB device using ehci_hcd and address 6
[85082.754586] usb 1-3: configuration #1 chosen from 1 choice

Can you "split" a network interface in Ubuntu, similar to how airmon-ng lets you use your wireless card in managed and monitor mode, by making another interface out of the same hardware? I know it'd be slower, but I'd still like to do it.

The good news: 11.4 seems to have much better support for my radeon graphics driver which makes many of my workarounds for 11.3 unnecessary
The bad news: whereas previously for 11.2, 11.3 using traditional ifup meant that I could easily restore internet (either wlan0 or eth0) with ifdown/ifup now this seems to have no effect. I haven't investigated further yet since without internet on hibernate or suspend 11.4 is not my grub of choice at the moment
There seem to be quite a few glitches with the 'stable' release of 11.4 but this seems to be the main problem for me. (Minimizing the beta 4 Firefox windows closing them is another...)

After updating to openSUSE 11.3, and restarting my computer, I placed my computer in sleep(suspend to RAM) mode, and I lost my internet connectivity. I noticed that my computer was only connected through ethernet. After entering "dhclient eth0" in a terminal, I received the following output.
Code:
RTNETLINK answers: Cannot allocate memory
This is the first time that I have had issues with connecting to the Internet using Ethernet.

If I suspend this toshiba satellite, and the battery is or gets low it will wake from suspend to tell me that it will need to suspend due to a critical low battery. Which is pretty dumb. I've experimented with this by plugging and unplugging the ac adapter.

3. i have a usb sound card (xfi go). when waking from suspend, the internal sound card is selected. i have to manually select the external sound card & for whatever reason, also unmute it too

To workaround the kio_smb madness, I set up shares to be mounted via /etc/fstab. It works flawlessly until I suspend my laptop. Coming back from suspend, samba mounts are not being re-mounted automatically. Since I'm new to opensuse, I wish to ask you:
Is there a polished way to make this happen, in opensuse approach?
Or shall I just go and toy with scripts in the init.d (or what is it in suse)?
As much as I could figure, I checked in yast, and smbfs service is signed as "Yes".
