Ubuntu Networking :: No Network After Resume From Sleep?

Mar 11, 2010

I'm sure this doesn't need a new thread but after searching for a bit I didn't find much about this. The problem is this;My system sleeps quite well, I can resume from sleep and get back to the desktop. However. the one thing that doesn't resume is > networking.I can disable> re-enable networking from the NM-applet and it tries again to connect but won't.I can sudo /etc/init.d/ networking restart, which essentially is the same as above. No connectionI've run ifconfig, and the connection is there but no address. Has this bug not been solved? Is it just a driver issue with my particular network card?It's the realtek 8201, part of the VT8237 chipset.Does anyone know what to do about this? I've been avoiding sleep mode on this computer for a very long time because of this bug.

Ubuntu Networking :: RT2860sta No Wifi After Resume From Sleep?

Oct 13, 2010

When my akoya mini E1210 with UNR10.10 resumes after sleep my wifi searches forever and then cuts out. When I do iwconfig the card seems normal for about a minute and then I do iwconfig again it gives gives no id. Reboot and bang, everything perfect. Did make new driver from latest ralink driver, as explained by Sven ,but nu change. Also blacklisted the rt2800 and rt2x00.

Seems that after sleep the wifi card driver is not loaded. Worked like a charm in 9.10 and in 10.4 (upgrade from 9.10). After update to 10.10, it went wrong.

extra: when I do sudo ifconfig ra0 up I get the message "SIOCSIFFLAGS: Operation not permitted" Also, after hibernation, no luck...

in dmesg found that the mailbox keeps MCU active, and rt2860 could not be initialised.:


maarten-laptop kernel: [ 1902.168454] ERROR!!! NICInitializeAdapter failed, Status[=0x00000001]
maarten-laptop kernel: [ 1902.168788] ERROR!!! H2M_MAILBOX still hold by MCU. command fail
maarten-laptop kernel: [ 1902.174003] !!! rt28xx Initialized fail !!!

When Evolution Mail is not used, everything is ok. I know this message is not related to mail, but it helps for a while. After longer period of sleep, same problem again. Firmware problem?

Ubuntu :: Bluetooth Does Not Work After Resume From Sleep / Standby

Jan 21, 2010

I just bought a Logitech V470 bluetooth mouse. It's no problem to let it work under Koala 9.10 (gnome), but after shutdown/standby/sleep, it doesn't work anymore. With my USB mouse, I have to click the bluetooth icon and select 'switch off bluetooth'. After that, I click 'switch on bluetooth' and bluetooth works again. I thought switching on and off bluetooth with the applet is the same as 'sudo /etc/init.d/bluetooth start/stop', but it isn't! The previous command greyes out/in the bluetooth icon, but it doesn't resume my bluetooth. If 'sudo /etc/init.d/bluetooth restart' would work, I would be able to add this line into /etc/pm/sleep.d, so it's automatically loaded on resume.

Ubuntu :: Sleep Resume Making Login After Upgrade?

Jul 12, 2011

I have upgraded from Ubuntu 9.x to 10.04 LTS after the upgrade, my netbook goes to sleep in a short period of time and makes me login every time i resume. This is very annoying as i have to wait for login and sometimes my wifi connection drops. I just quickly want to check my messages. The delay is annoying and has me using a windows (argh) laptop instead. i miss my ubuntu netbook.

i have tried adjusting power management setting to never go to sleep and adjusted some other power management module from the command line, but with no luck. is there a way to reset the sleep pref's or any way to fix this.

Ubuntu Networking :: Network Manager Will Not Auto-connect To New Network After Resume?

Jul 1, 2010

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:

case "$1" in

Just recently I notice this behavior. When the machine sleeps either on timeout or after closing the lid, it doesn't come back on opening or hitting esc etc..

Fedora Hardware :: FC13 Mouse Cursor Disappear After Resume From Sleep

Jul 24, 2010

Running FC13 on Dell E6410. Everything was great until I ran the latest update about a week back. I started to see (or actually not see) that after resume from sleep the mouse cursor will disappear. It is there, just not work showing. If i click on left click on the desktop I get the menu, I can also "see" going over windows from time to time as I move it. I'm currently running I think previously it was /vmlinuz- Nvidia driver is 195.36.31

Ubuntu Servers :: The Server Goes To Sleep It Can't Be Reached By Network?

Feb 3, 2010

I've installed Ubuntu Server 9.10 on a small VIA C7 pc. Every now and then (it can take days or hours) the server goes to sleep. It can't be reached by network. If I hit the keyboard it comes to life within a second.I've looked in the bios and I cannot find any option that would prevent this. I used to run Debian Lenny on the same machine and never experienced the problem.

OpenSUSE Network :: No Internet After Resume From Hibernate Or Suspend?

Mar 13, 2011

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...)

OpenSUSE Network :: Networkmanager Causing Freeze On Resume?

Jul 23, 2011

i've been able to narrow down a freezing issue on my laptop, down to NetworkManager when i have a cifs share mounted in fstab.removing the cifs mount, or using 'ifup' method appears to fix the issue.the problem is when my laptop resumes from sleep, and when using NetworkManager with cifs share, then i get a 20second freeze when using the launcher while the network sorts itself out. this happens on either wifi or wired connections. this freeze only occurs when using the Launcher for the first time after resume. if i dont use the launcher then everything is fine untill i do (ie: i have network access and desktop shortcuts work fine)

OpenSUSE Network :: Samba Shares Stay Unmounted After Resume From Suspend

Mar 15, 2010

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".

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.

This is the first time that I have had issues with connecting to the Internet using Ethernet.

Debian :: No WiFi After Sleep And Boot - Network Manager Cannot Find SSID

Apr 4, 2016

I'm running Debian testing. I am running the iwlwifi driver and I have an Intel Centrino Wireless-N 1000 card. I have a fresh install of iwlwifi and network-manager. After sleep or after being shutdown, network manager cannot find my network's SSID. I have to wait ~5 minutes for it list my SSID. I dual boot this laptop with Windows 7, and on Windows, I connect to the internet instantly after boot. I did not have this issue before, the only thing I have changed was installing blueman and the necessary components. After I installed and uninstalled these bluetooth components, I have been getting these problems. Here are some outputs:

Code: Select alleth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"Dotcom"

Ubuntu Networking :: Continue Networking When In Sleep Mode?

Nov 9, 2010

After seeing those 4G phone commercials with that newfangled mobile hotspot tech, I have to admit I was eager to trade in my crappy 2 year old CDMA phone for one. That is, until I saw the price tag. 30$ a month for hotspot? No way, so what I did was activate the tethering feature buried deep within the primitive OS accessible only with a plethora of codes and hackery. So long story short: I can now network on the go because Ubuntu sees my device as a "mobile broadband device". Unfortunately, my ipod lacks a USB port for tethering so I use my freed up wireless card to make an AD-HOC network for my ipod to connect through my makeshift modem. Now, my issue is that the modem isn't really that mobile any more because I have to have my laptop OPEN to keep my networks on ,otherwise I close my laptop and no more Adhoc or mobile broadband! So, my question is if I can close my laptop but still keep it connected to the mobile broadband and broadcasting the adhoc network.

Ubuntu Networking :: Wireless Won't Resume In 10.04

May 7, 2010

I've read many threads here on wireless problems in 10.04. I've got it updated as of this morning.

Symptom: wireless works perfectly - doesn't drop out and starts right up at boot. But if computer (Dell Latitude D505) goes to sleep, wireless won't resume. Network Manager shows wireless networking greyed out after waking.

Here's output that should be helpful:

xxx@xxx-laptop:~$ sudo lshw -C network
[sudo] password for xxx:
description: Network controller
product: BCM4309 802.11a/b/g


I've read in several other threads here that blacklisting the wireless driver file(s) may resolve the problem.

- What driver file(s) on the computer do I blacklist?

Ubuntu Networking :: Wireless Lan Doesn't Resume?

Jan 19, 2010

I'm setting up an HTPC (Zotac IONITX-F in a Silverstone ML02-MXR case with remote) running XBMC on top of a minimal karmic install. So far I've managed to get everything running including the tricky stuff: wireless, lcdpro and lirc. I did have the same samba/dhcp conflict described in this thread, so I opted for a static IP solution instead of the usual dhcp connection with the router (D-link DIR-615) reserving an IP for the MAC-address. This is my /etc/network/interfaces file:

auto lo
iface lo inet loopback
# The primary network interface
#auto eth0
#iface eth0 inet dhcp

Ubuntu Networking :: How To Resume SSH Session After Disconnecting

Mar 7, 2010

I'm currently using putty on my laptop to control my headless server (both Ubuntu 8.04.) I'm running an rsync job that ran all night long and still going all day today so far. I need to restart my laptop, but if I do, I'll break the SSH connection. If I SSH back in, I won't see the same thing (rsync is showing me each file it's copying) that I'm seeing now. (At least I think that's true. Please correct me if I'm wrong.)

So I guess my questions are..Is there some way to restore my SSH session when reconnecting? (So I can resume seeing which file is being copied and - more importantly - when the rsync job (finally) finishes?If not, how else can I know when the rsync job finishes?

Ubuntu Networking :: Wicd Won't Connect After Suspend / Resume?

Apr 10, 2010

i just installed ubuntu 9.10 netbook remix on my acer aspireone ao532h netbook, and so far, it's been working beautifully. much better than the windows 7 starter edition that came with the machine. the only problem i've experienced so far had to do with the wireless connection. initially, the connection would drop during certain types of activities (e.g. downloading updates or programs, or even streaming videos videos) and the network manager would freeze so completely that i'd have to hard reboot. that seems to have been fixed by installing wicd (following a suggestion here: http://ubuntuforums.org/showthread.php?t=1135723&page=2), meaning that it hasn't disconnected in the several hours since i've been using it. however, wicd has a different problem: it disconnects after a suspend / resume cycle. this requires a reboot to fix also, as not only does it disconnect, but it looses awareness of the network altogether. obviously, this could be a real headache on a netbook that gets closed and opened frequently.

Ubuntu Networking :: No WiFi APs After Resume From Suspend / Hibernate

Aug 30, 2010

After I resume from hibernate with my cpu frequency manually set to the highest settings (2ghz) the network manager shows not wifi APs. "wlan0" shows under both ifconfig and iwconfig but "iwlist wlan0 scan" says no results. "sudo iwlist wlan0 scan" also says no results. I've tried rmmod then modprobe with no luck. Rebooting is the only way I can get WiFi working.

I can get wifi working again by:
- rebooting
- changing the cpu scaling to a lower setting then hibernate/resume
- changing the cpu scaling to a lower setting then 'sudo rmmod ath9k; sudo modprobe ath9k;'

I am using Ubuntu 10.04 with Atheros ar5008 (AR5BXB72) using ath9k drives
$ lspci |grep Atheros
0e:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

Ubuntu Networking :: Lost Wired Connection After Resume?

Jun 27, 2011

So, when I booted up, the wired connection was automatically detected and in use. Whenever I suspend my computer and then resume it later I lose the wired connection. It is detected (seen) by Networkmanager, but I can never connect. I found a way to restore the connection, but it is manual and I was wondering if I could automate this process every time I resume. Details follow:

Laptop: HP dm1z, Natty 64bit. ethernet card:

#lspci|grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
Likely culprit (according to dmesg)

Ubuntu Networking :: Lose Wireless On Sleep And Hibernate?

Apr 27, 2010

If I put my computer into sleep or hibernate, I have no wireless connection when I start up again. I click on the wireless manager in the tray, but wireless is disabled and I can't enable it. This never happened until I updated to Ubuntu 9.10.

I am using the b43 driver (I think), but I'm not sure which command to execute to display information about my wireless card.

Ubuntu Networking :: 10.10 + Eee Pc 1000 After Sleep Wireless Turns Off

Oct 31, 2010

I use ubuntu netbook for an eee pc 1000h because windows is underpowered. I got it working perfectly in 10.04. I upgraded to 10.10 thinking, if they got it right with 10.04 then surely 10.10 should be fine. All function keys except wireless work.

1. After sleep, wireless turns off. Have to restart and re-enable in bios.
2. If I disable and the re-enable wireless networking it tries to connect but never does resulting in a reboot needed. Checking bios wireless is enabled and connects perfectly on reboot.

Just don't close the lid and sleep because you need a restart. Why would 10.04 be easy and the new version fail? I am windows user and linux does not do this kind of thing normally. MS screws things up with upgrades not linux surely.

Ubuntu :: "Network Disconnected" Popup After Sleep Not Disappearing

Jul 2, 2011

I am running Xubuntu 11.04. A popup that reads "Network Disconnected - You are now Offline" appears every time I disconnect from a wifi network. disconnected.png This is normal and OK. Every time I suspend my computer, it disconnects from the network. This is normal and OK. When the computer wakes up, it displays the popup. This is annoying. This popup does not just fade out like all the other ones, I have to manually close it. This is very annoying. The very first time the popup appeared, after installing Xubuntu, the popup had 3 buttons that all read "Don't show this popup again," I clicked all of them, hoping that one would work. apparently they didn't. How do I get that popup to not show up after going to sleep, but still appear under other conditions. If that isn't possible, how can I make it automatically fade away/disappear?
