Ubuntu Networking :: How To Change Pm Mode For Wireless On Battery
Oct 31, 2010
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?

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.

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 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

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?

I have a new Lenovo (thinkpad) x100e laptop. I've recently installed the new Ubuntu 10.02 distro and have found the oddest bug. If my power cord is disconnected (i.e. if I'm running off battery power) then the login window locks up. Conversely, if the power cord _is_ connected then things work as usually. (Also, trying to adjust brightness causes a crash --- but I suspect that this is not odd). Where I should put this information.

I started having this issue two days after installing openSUSE. When I try to boot it on battery (that is, without a energy plug) the laptop just turn off right at the beginning. I have other OS's installed and they are working properly and booting when in battery mode. I haven't got a clue of what I need to check to fix this, can anyone help me out? My laptop is a vostro V13.

I am using Ubuntu 10.10 on an IBM ThinkPad t43. I have a 9 volt battery that I use only occasionally. Usually I use the AC connection and when I'm finished working I leave the laptop in "sleep" mode. (Not always, but often.) When using the AC is it okay to leave the battery in the computer or is it better to remove it? Some swear it shortens the battery's life to leave it installed when not in use. Others swear--with equal fervor--that the newer ion batteries know when they are fully charged and don't have to be removed. Which is true? It's inconvenient to keep taking the battery in and out, but if it's necessary to prolong it's life I guess it's worth it. Some clarity good because, as I said, you can find equally impassioned arguments for both sides of this issue.

I use to have problems getting my wireless card to connect to any network on ubuntu. I discovered that I needed to change my encryption mode from Auto to AES or TKIP on my router. After I did this I was able to connect to my network with full wireless n support. I am using a d-link DIR-615 wireless n router.So far I know this works perfectly on 9.04-10.10 alpha.

Code:
root@Atlantis:~# iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
root@Atlantis:~# iwconfig wlan1 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan1 ; Invalid argument.
All other modes except secondary work fine.
The wireless cards are both PCI, a Netgear WG311v1 and a Linksys WMP54Gv4.1, though I'm not sure which is which.

I have a built in wireless card that is capable of connecting to my network on the Wireless N protocols. However it will only work at G speeds. It shows it's connection speed at 54mbps and when i set the network at N only mode it could not even connect. How do I get it to connect at the faster wireless speeds? I need the faster speeds as I have a media server on my network. This is the hopefully relevant information you'll need from my network

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've searched for too many days and nights so many information went through my head. I want to buy a usb wireless which support master mode. (not monitor mode) Now I'm interested in Alfa AWUS036NEH. I like it because it is small an have a long antenna strong 1000mW. signal. (AWUS036H is a little bit big for me) However from what i have read AWUS036NEH is not supported in master mode (softAP)(or may be supported but with hostapd, but again some forum said it doesn't support and some say it does... Totally confused.) -> Actually AWUS036NEH is not expensive but I don't want to invest in something i'm not sure about so I won't buy it until I really know if it works. So I switch to find out what is for sure
1. supported in master mode in Ubuntu
2. Have a long antenna (like 5" or something. I have no idea about hardware but I think longer antenna should send signal more further)
3. small (about normal USB size don't count antenna)
Sadly I only find Alfa AWUS036NEH the only option for me , the others has no brand. However TL-WN722N is what most likely to fit. Only it has a shorter antenna. Can i replace the antenna with a longer one (with some others brand) by myself? (TL-WN722N can use master mode in kernel 3.0 ? already ? some say it should but i've not seen one that stated clearly) Ahh I think the above is totally messed up. I will make long story short.
1. Is AWUS036H or AWUS036NEH support master mode in ubuntu ? (if yes with hostapd or something?)
2. Is TL-WN722N or TL-WN722NC can work in master mode in Ubuntu ? (if yes with hostapd or something?)
3.Can I replace the original antenna with a longer one ?(with other brand or same brand) Will the signal be stronger?

I am running a version of Ubuntu 10.4 with XFCE loaded (actually Qimo, a distribution for kids). I am using a pci wireless card with a broadcom 43XX chipset and WPA2 authentication using the Broadcom STA driver. In an account with privileges I set the auto eth1 (which is what my wireless card comes up as) to connect automatically, and make available to other users.
When I switch to the kid's account, the wireless connects just fine. Then, if the computer is not used for a period of time, the powersavings mode kicks in. When the computer is woken up, the wireless connection does not attempt to reconnect. If you right click on the networking icon it doesn't even show any available connections, even though it can be found by clicking edit connections. The only way I can get it to reconnect is to restart the machine (I will admit that I did not try to restart the networking service, I will try that tonight).
Any ideas? This has been driving me nuts for a few days now. The users during the day are non technical and can't deal with these kind of issues. I can post more details about the setup (as recommended by the sticky post) tonight. I am at work at the moment and can't get to the machine from here - because it has removed itself from the network again.

I'm a student who is working on a wireless research project. I have a madwifi driver for Atheros chipset on Debian Linux. With having the wireless interface get into monitor mode, I want to forward the captured packets from the wireless interface to the other Ethernet interface so that a different computer which is connected to this machine via Ethernet receives those packets. I checked that alll packets are received in the wireless interface using TCPDUMP. I tried to forward those packets with IPTABLES like 'iptables -p FORWARD -i ath0 -o eth2 -j ACCEPT' However, I couldn't see any packets forwarded to eth2 using TCPDUMP.
