just installed Ubuntu on my Macbook Pro and im loving it right now, but whenever I disconnect from the power source and run from battery, my wifi Internet slows down to a crawl. As soon as i plug the power back in, the internet is back to normal.

View 9 Replies View RelatedI 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.
View 4 Replies View RelatedI 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.
Anyone have solutions for this problem: Can not establish or re-establish wireless connectivity while on battery power. Below are specifications

I have a Dell 1501 Inspiron laptop and have swapped out the broadcom network card for an intel 4965AGN so I can use n-speed with my new router.Everything works sweet except my laptop now crashes if I try to run on battery power.It boots up to the login screen, but once I enter password and login it crashes, just get grey screen and everything locks up. Everything works fine on mains ?It's not a major problem for me as I don't use the laptop "out in the wild".

View 7 Replies View RelatedI have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.
View 2 Replies View RelatedI'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 am using a Fujitsu Amilo pi3560 with a Realtek rtl8172 wireless card, and running the latest driver (rtl8192se_linux_2.6.0014.0115.2010). The OS is Ubuntu 9.10.
Everything runs perfectly - when my laptop is connected with the power cord. But when I go battery the wireless disconnects after a few minutes. It then asks for the wpa password, searches for the router, asks again, and so on indefinitely, until I reboot and it all replays once more.
Running Ubuntu 10.04. Networking won't work at all. Used to work flawlessly. Problem is not hardware, because booting windows (vista) on the same machine I can still use networking.
Little story: I Was going into a short trip, then I put my computer to sleep (as usual). Trip took longer than expected and, when I came back, the notebook battery was dead. Charged it, booted the notebook (Dell Inspiron 1525) and now its network won't work at all. After reboot it even ran a filesystem scan, but problem wasn't fixed. The icon on 'taskbar' only says "networking disabled". The ethernet lights won't even light up when I connect a ethernet cable and it won't see any wifi networks. I've tried to fiddle with that little switch which would turn the wifi on and off, but all it seems to do is turn the Bluetooth on and off, as shown by the little Bluetooth icon on 'taskbar' (I've not tested bluetooth, though). I've also tried to plug a external wifi dongle but ubuntu won't even try to install it.
what's happening or what could I do to get my network working? Is there some 'magic' I can type into a terminal window to make this work?
I am using ubuntu 9.10. in my area there are frequent power outage. So my wifi get disonnected as the router stops. And it asks for security code. So when power comes the router starts but i have to manually write the security code and connect to wifi again. how i can make the computer to auto connect to wifi after power comes.

After upgrading from 10.10 to 11.04 via the online upgrading method I had much trouble getting wireless to work but after following the instructions at .Driver/bcm43xx it burst into life, that is until I powered off and now I have to sudo modprobe b43 before the hardware button for the wifi will work and and then I am able to get online. This is for every power on session!! Once enabled it will switch on and off via the hardware button and the light is operational. Before the sudo modprobe b43 the buttonoes something as evidenced by sudo rfkill list after each press of the button. Is there any way to have the command sudo modprobe b43 inserted somewhere in the power on sequence? This was a working function on 10.10!

I have tried the two available networks on my university campus and both of them are very slow with 10.04. I'm not having problems with Windows 7 running on these networks. Although, the wired network works perfectly fine, with normal speeds. I've looked around for help but I could not find anything specific to this problem.

View 1 Replies View RelatedI'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 am running 10.04 on an Acer Aspire One
Since my upgrade from Lucid my battery icon displays permanent full charge even when running without AC power. When the battery runs out, this leads to an immediate violent shut down, everything dies at once.
My power management settings for running on battery are as follows;
1 hour
Blank Screen
Hibernate
Yes
10 MIns
Yes
I was introduced to Ubuntu about a year ago and recently decided to come back to using the OS. I now dual boot it with Windows XP Home. My former setup was with Wubi but now I have it installed on an actual partition. (The Wubi install, for whatever reason, had little internet problems.) I use wireless internet, and though my network card was recognized out of the box and can connect to my network, the Internet is very slow. It takes almost a minute to look up Google. Also, Firefox will often report that it cannot find the server for whatever website I try to look up, after trying to connect to it/look it up. I also cannot access the web configuration page for my router. (192.168.1.1). The network app reports that I often have a signal strength of 40% or lower. The following is my hardware/internet:
Ubuntu 9.04 Jaunty
TrendNet TEW-424UB adapter (54mbps)
Westell VersaLink 327W router
ISP: CenturyTel/CenturyLink High speed internet (512kbps)
I am the only Linux computer on my network. (There is no encryption on my network. I know there should be. but my parents are not very computer literate and they are the ones who have access to the network. It is easier just to go without.)
I have tried disabling ipv6, setting custom DNS server names under ipv4, and setting the wlan rate (or something similar) to 1492. Nothing works. This does not seem to be a network problem because my internet works fine in Windows, and I can access the configuration page for my router to change channels, PPP, etc..
I have 1 router 2 pcs. We had to move one pc away from the router so I bought a wifi card. Everything went fine, the card works and I have internet but the network is incredible slow.

I am using Fedora 12. Prior to this I was using Ubuntu 9.10. In Fedora 12, I am facing a problem with battery power. Sometimes when it is fully charged I remove the power cord, battery power comes down to 40%-41%. It never happened with Ubuntu, which gave quite a good battery performance. My question is when it is showing Laptop Battery 100% i.e. fully charged, if I remove the cord why it comes down to 40%-41% (and always in this range).
