Ubuntu Networking :: 10.10 Freezes When Using Wireless On Battery?
Nov 28, 2010
Unlike a lot of others, I have had no problems getting the wireless on my Dell Studio 1558 working with the STA driver. As long, as I am not on battery, that is. Within minutes of switching to battery and disconnecting from the LAN, my system freezes: I cannot move the mouse, the keyboard is useless (I can't even Ctrl-Alt to a terminal) and my only option is a hard boot.I currently have the 2.6.35-23 kernel and I have tried the following driver options for the wireless (all the below were tried with 2.6.35-22):
- the Broadcom STA driver in the repos- the latest STA dirver from Broadcom- the new broadcom driver, not yet available in ubuntu repos (brcm80211)- ndiswrapper ( I can only get win 7 drivers for my laptop, so this does not even enable the driver)My Wifi card uses the BCM43224 chipset.After a freeze, I have pored over the logs and I cannot find any obvious error messages preceding the event - so I am a little at wit's end ito resolving this. Can anybody give me any clues as to where I should start looking to resolve this issue?

I have Ubuntu 10.10 running on a Dell Latitude E6500 notebook and am using the Broadcom STA wireless driver (just in passing, same happens on Mint 10).
My problem is this:
- when the computer is plugged into a power outlet, wireless works fine, but
- when the computer is running on battery, it hardly works at all: The network strength indicator item still shows the same connection strength but data are not transmitted anymore or only extremely slowly (google.com might 2 minutes to load).
The drop in performance literally happens 1 sec after unplugging it, and once the notebook is plugged into external power again, it resumes after a few seconds. (I have tested this with big downloads where you can see Firefox's or the Update Manager's download speeds.) The BIOS doesn't seem to have power saving settings that make that happen, and I haven't found any in Ubuntu.

Hardware: Vostro 3500, BCM4353Ubuntu 10.10Today I decided to test uptime on battery. But when I started using battery I noticed that internet connection is very slow(around 1-4 KB/s, normally ~128KB/s).I used Code:iwpriv eth1 set_pm 0(pm = power mode? And what means this parameter 0, 1 and 2?)and everything seems to be ok now.And my question is - where can I edit which power mode settings for wifi are used on battery?

I am running Ubuntu 11.04 32Bit on an ASUS Eee PC 1015PX. I have found a strange anomaly concerning wireless connection when running on battery power. I have been experiencing very slow performance when connecting to my home NAS and also the internet through a wireless connection when using my netbooks internal wireless card (Broadcom Corporation BCM4313 802.11b/g/n (rev 01)) when running on battery power. The card works fine and connects at full speed when running on mains power but as soon as I switch to battery power the card connects to the internet/network fine but the connection speed is very slow indeed. I am using the Broadcom 802.11 Linux STA propriety wireless driver.

I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.
It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.

I have a problem with my wireless where when running the laptop from the battery the connection is very slow. When the laptop is connected to the power supply everything is fine, but the moment it's disconnected and run on the battery the speed drops when browsing the Internet or accessing files on other computers on my network.
The laptop is a Samsung SF310
Wireless chipset is BCM4313
Code:
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g LP-PHY (rev 01)
Subsystem: Wistron NeWeb Corp. Device 051a
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at f4c00000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl
In attempt to fix this I installed the latest drivers from the Broadcom site using this guide. When I enabled these drivers everything worked well. I did speed test and got the same speeds I get when connected via Ethernet:
Ping 51ms
DL 4.31
UL 0.65
So I set the drivers to load at boot using this forum post as a guide as the steps in the Broadcom guide didn't work and rebooted the laptop on battery power. The wireless connected fine, but the slow speed problem had returned. Running a speed test got the following results
Ping 235
DL 0.54
UL 0.30
So I ran iwconfig when running from battery and then from power supply.
Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:215 Noise level:160
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
As can be seen the signal quality is 5 and signal level 215
Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:214 Noise level:164
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
And when connected via the power supply the signal level is 5 and signal level 214. There may be some kind of power saving issue, although there are no relevant setting in the BIOS and I can't see anything in the various wireless control pannels. I have other wireless drivers and there are no problem with those.

I'm running 11.04 on my Dell SXPS 1645. Today I unplugged my laptop from AC power a few times and after about 10 minutes, Ubuntu would hang, not responding to anything. Frozen mouse, frozen keys. The ONLY thing I could do to get it out was to do a hard hardware restart by holding down the power button.
It happened twice on Skype (and I thought it was just the buggy 2.2 beta that was hanging my beautiful OS), once while installing a printer, and once while I was just futzin around on firefox.

I have an Asus Eee PC with Ubuntu Netbook Remix (Unity). The other day, I turned off the wireless using the keyboard shortcut to save battery life when I was somewhere without wireless, but now it's not turning back on. I tried restarting, I've done the keyboard shortcut several times, and it still just says "disconnected" for wireless and wired, even though there are several wireless networks around me right now. There aren't any options in Network Connections or Network Tools to turn on the wireless. Is there a way to manually turn it back on?

When I'm running the laptop on battery the desktop freezes. It doesn't matter what program I use, it also happens when I just boot the system login and do nothing. I then have no mouse, no keyboard - so no key combination works. The only thing I can do is turn the laptop off using the power button and turn it back on. Usually the desktop freezes with in 5 min after login, but I also had one case were I was able to work for about 2 hours. When I plug in the power supply everything works fine.

I have an MSI Wind U120 netbook (Intel Atom N270 1.6GHz processor, 1 GB RAM). I'm running Ubuntu 10.10 Netbook Remix. Ever since upgrading to Ubuntu 10.10 from 10.04, my system has experienced unrecoverable freezes when running on battery. The system reliably freezes when resuming from the suspend or hibernate modes when running on battery. It seems to load back up successfully but then freezes before I get a chance to enter my password. Yesterday and today I also noticed that the system freezes while idle and running on battery! This is even more disconcerting.
I have some experience as a Linux user (including using the terminal & editing configuration files) but not much experience as a Linux system administrator.

I upgraded to 11.04 yesterday but when I try to run it now it freezes on checking battery state. I've did some looking in the forums and found this post. [URL] Which in turn pointed me to this page. [URL] I have an ATI Radeon 5450 so I went through the steps for Need to fully remove -fglrx and reinstall -ati from scratch
Now, when I try to start up the screen just goes blank as if I've turned the computer off. I can run the system in limited graphics mode (or whatever it's called) so I have the ability to do some troubleshooting there, but I'm a Windows convert and am pretty hazy as far as Ubuntu troubleshooting goes

I have Evoluent Vertical Mouse connected via USB. It would work fine connected to my laptop on AC power, but it would freeze when on battery.I have "laptop-mode-tools" installed, and I traced this problem to laptop-mode-tools trying to put the mouse to sleep and not waking it up.To solve this, I have blacklisted the power management for the USB mouse. First, I did "lsusb" to find the mouse device:
Bus 002 Device 003: ID 1a7c:0068 Evoluent VerticalMouse 3..And got the ID of the device. Then I edited the laptop mode configuration and added this id to the blacklist:
/etc/laptop-mode/conf.d/usb-autosuspend.conf
edit this line:
AUTOSUSPEND_USBID_BLACKLIST="1a7c:0068"

I've got a problem with my laptop and I finally decided to try to solve it. My computer sometimes (not everytime) freezes. It's just when I'm using battery power. I figured out that this is not connected with some specific action (e.g. some app crash), it can freeze 1 minute after start or 10 minutes, I think it's random. I've checked my /var/log/messages.log file and these are the last messages before freeze (exactly at 9:16:15):

After a successful install of the MFC-J4420DW printer and scanner using Brother's install utility, I am experience severe battery drain and xsane freezes (total system lockup, requiring using CONFIG_MAGIC_SYSRQ keyboard command REISUB or hard reset).
The Brother support page and utility/drivers are found here: URl....My laptop is the HP Elitebook 8540W and I am running Debian 8 using LVM, separate partitions for /home, /var, /temp, /swap, and /. I have looked at logs in /var/log. kern.log, daemon.log, messages and dmesg, but have not found any relevant info ...
I purged all drivers/packages and tried a manual install using each deb package, but ran into some permission errors, so I purged again. I also purged xsane and reinstalled it, then did a complete printer reinstall using the brother Driver Install Tool.The tool works great, full functionality for the MFC-J4420DW. But I know I can't live with the power drain, and I would really prefer to use Gimp and the xsane plugin rather than simple scan ..

I have a Wubi installation, and the upgrade to 10.04 froze. I didn't note down the point at which it froze.
When I tried to reboot, I got the grub screen, and when selecting Ubuntu I get lots of text messages scrolling by, but it freezes at battery check.
The machine boots fine into Vista.
Rather than spend a lot of time trying to figure out what went wrong in the upgrade, my inclination is to delete the Wubi installation from within Windows, and then do a fresh install of 10.04 under Wubi. Is this feasible/sensible?
There are a handful of files I would like to salvage from the prior installation, however. Could I do that with a Live CD since the prior installation was under Wubi?

I did normal net upgrade after the official release of 10.10 yesterday evening. On reboot I get a frozen system with a blank screen. Checking via safemode, I find it is stuck when 'checking battery state' but this is a desktop machine! Apt update, uninstalling ubuntu-desktop, reinstalling ubuntu-desktop, etc.

Since I upgraded to Lucid, I am dealing with serious instabilities related to my wireless card. What happens is that when there is a lot of wireless activity the computer freezes. It is a complete freeze, the mouse stops moving, if something was coming out of the speakers it keeps echoing, and the only solution is to turn off the computer. The bug seems to coincide with the one listed in here
[URL]
My wireless card is Intersil ISL3890/ISL3886. My whole computer is an HP z555. I'm thinking that is should be a bug in the wireless adapter driver, which is p54pci. The only solution I can think of is to blacklist it and set up ndiswrapper. I am not very comfortable with this solution since a native linux driver should be better than ndiswrapper.

I've got an atheros ar9287 based card with the ath9k driver from the base install of lucid and I installed a compat wireless patch via this thread: [URL]... to fix the issue of the card being stuck on a given channel when using aircrack. Now, my system freezes up after about a minute or two. If I leave the wireless card off, everything runs fine no problem. I uninstalled the compat wireless driver via the readme just make uninstall in the compat-wireless folder, but I still get the freezes. So I assume it has something to do with the patches. I have no idea how to remove the patches. Can anyone help me with this or is there a way to get everything up and running so the original problem of being stuck on a channel is fixed?

I upgraded Ubuntu 10.10 to 11.04 on my IBM Thinkpad T41. [URL]... Since I did this, my gnome desktop freezes constantly after I connected to a wireless lan. It doesn't freeze immediately but a couple of minutes later. syslog gave me the hint that it could be a mistake in loading a module for my intel wireless card. syslog:

I am using Fedora 8 on my laptop, newly installed, I can see the network card(Linksys WPc54G v2) and Network Manager sees the wireless router, however as soon as I tell it to connect my computer freezes and I have to restart. I searched for solutions but all I found was Ubuntu problems.
Actually it seems that the trigger is when the keyring comes up and asks for a password. As soon as I start typing the pass it locks.

I've been using a Netgear WG311v3 wireless card to connect to the internet successfully since 8.10. However, since 10.04 I've had some serious issues with this card (at least...I think it's the card). I updated to Meerkat hoping that the problem might fix itself, but it's still there. Here's the situation: The problem most often occurs when I'm running Transmission, but also Firefox. It also happens when streaming videos to my xbox via uShare...basically, any time I'm using the internet.
Suddenly, my download in Transmission will drop to 0.0 KiB/s or in Firefox, pages will stop loading. If I close and try to reopen Firefox, it tells me the process is already running. If I try to restart, it says firefox-bin is still running. I click reboot anyway, and the computer hangs indefinitely at the purple Ubuntu shutdown screen. The terminal also freezes if I try to run any commands that are wireless related, for example iwconfig or ifconfig. I have to close the terminal to kill the process.
I've also had more serious crashes when running Transmission where absolutely everything freezes and a hard reset is my only way out. Forgive my n00bishness and let me know what other information I can provide you with.

I just got a Lenovo Thinkpad x100e. Everything seems to be running well, with this exception of the wireless adapter. When running on the battery the wireless runs for about 30secs to 1 minute before dropping out. The NetworkManager says it's still connected, but nothing goes across the network. Disabling and then re-enabling the wireless works, for about 30 sec to a minute. The weird thing is this behavior DOESN'T occur when the power adapter is plugged in.
I'm wondering what power management parts I should be looking at? I'm running OpenSuSE 11.2, KDE 4.3.5 if that helps.

I have 64bit ubuntu 10.04 installed on lenovo ideapad y450. recently, i ended up using the laptop on battery till it died and the wireless doesnt' seem to work after i restarted the laptop after connecting the AC adapter.
When i go to network manager, i see wireless is grayed out and it says it is disabled ( the hard switch on the laptop for wireless is turned on).
Doing some research on forums, i did a sudo lshw -C network and the first line of it says *-network DISABLED and the description is for wireless interface. I can't post the output of the laptop as i don't have a LAN connection or a usb drive to which is can copy and then post it here.
The product is PRO/Wireless 5100 AGN [shiloh] Network Connection from Intel
When i did the rfkill list, i got:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

I have been using Ubuntu without any problem for 2 years. Yesterday, when I booted Ubuntu, its power management is not working at start up: icons for battery, speaker, wireless not there + light icon says "cannot connect to gnome-power-manager".( in the screenshot) When I go System - Preferences - Power Management (1), it corrects only the light icon.I could only bring back wireless icon by "nm-applet" after doing (1).But other icons are not there still.
