Ubuntu Networking :: WiFi Disconnects After AC Power Is Unpluged From Laptop?
May 11, 2011
About 20 seconds after I unplug my Laptop from the AC adapter myiFi connection disconnects. The only way to get a connection again is to shut down my laptop and remove the battery and the AC adapter (WiFi-adapter reset) and reboot my laptop. I'm running 10.10 32-bit.lspci shows me these information about my WiFi-Adapter
02:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

I have a Dell Studio 1737 running Ubuntu 10.04 LTS.My WiFi was working fine a few days ago until I tried to boot into another mode that allows me to boot into my other Ubuntu 10.04 or Windows Vista.I booted into that Ubuntu, which I thought had been overwritten when I was having problems and installed the one I am currently using.I shut down since it didn't have anything of any use to me at the moment, and I booted back into this current Ubuntu.Now, whenever I shut my laptop screen and open it back up to login, the WiFi is disconnected.(I was also having this problem on the Ubuntu that I booted into earlier, but that WiFi did this from the start on that one.)

I have a Lenovo T440p.I am on Debian Jessie. I use KDE as my desktop environment. My Wifi adapter is Intel® Dual Band Wireless-N 7260. I have configured my laptop not to suspend itself when the lid is down. I can verify that the laptop still runs when the lid is down, because I can hear the music if it is already playing. However the Wifi always disconnects when the lid is down. If I am downloading a file, it always gets interrupted.

I've got a Toshiba Satellite with the Realtek rtl8188ce network card. I've successfully downloaded, compiled and installed the driver and it works great except when running the machine on battery power when it constantly disconnects, like every minute or two.

I have experienced sudden wifi disconnects. My laptop fails to reconnect even after repeated attempts. It is only after a reboot that I am able to connect to the wireless.

I 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.

After a new fresh-from-DVD install of Fedora 14 64-bit (over top of Fedora 12 64-bit which went over top of Fedora 10 64-bit before that) my Linksys WUSB600N adapter connects at login to my WiFi N router with WPA2 Personal.
That is great, as previously (fc10/12) I had to use the Ralink drivers per ogetbilo's thread on this forum (that thread kept me on the net for many years now). And at some point this even became a pain because sometimes the system would boot and refuse to connect to the wireless (which would hang trying to connect) and then crash to a dump screen on shutdown (bug reported). The fix was hoped to be found in upgrading to F14 and the newer kernels with working native Ralink chip support.
But I still have an issue... the connection stays up for a few minutes then drops. If I disable/re-enable wireless it (at least sometimes) re-connects. But obviously that is not workable. This is a USB adapter and I am not entirely sure that there is not some USB powersave issue going on, but I do not see anywhere to disable system USB power saving either.

I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.
I've tried :-
-disabling ipv6..... first in Firefox, then in Kernel also
-Setting DNS.....System> Preferences> Network Connections
-setting static Ip
The system still gives trouble.
My system is Asus UL20A.
Wireless:-Atheros AR9285

Running Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).
It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.

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!

have Karmic Coala runing on an IBM thinkpad X.41. Works great. My home network is all ethernet so I have a router , CAT5 cable to laptop.A coupleof times I've had power outages The laptop carries on as it's on battery power. When the power comes back , the router restarts, it reconnects after a few minutes but the laptop doesn't reconnect to the network seamlessly. On some other Linux distro's I've had running /etc/init.d/network restart will refresh everything. On Ubuntu I have /etc/init.d/networks but running restart In the end I needed to reboot the laptop to get the network back on.Perhaps this is a power management issue with the laptop ethernet card i.e losing power powers down the card and it never comes back up properly.

I just installed 11.04 on my laptop and the wireless works fine connecting to a AT&T 2Wire router when the ac power adapter is connected. When running on battery power I stay connected to the router but barely any information is transmitted. ie. if i restart the router connection on my computer I can load a web page like google.com then nothing else will work unless I restart the connection again. If I am right next to the router it will continue to work but very slow ( takes about a minute to load ......com when it only takes 2 seconds on ac power ). When I run windows 7 everything works fine when on battery power.Also every thing works fine on a linksys router with ac and battery power.Dell Inspiron 14R Processor: i5-2400MWireless Card: Intel Centrino Wireless-N 1030Ubuntu 11.04 Natty Narwhal

I have just installed ubuntu server 10.04 LTS on a laptop, and I would like to control it remotely.When I manually turn on the computer I can successfully use SSH commands to turn it off. But when I wake on lan turn it on, it doesn't power off. It hangs on a black screen where the fan and the hard drive seem to be off, but the ethernet light is on and so are all the computer lights.

I just upgraded from 10.10 to 11.04 but other than that the most annoying thing I've found is that my wifi will randomly disconnect from the network...like it will say its still connected but pages wont load and all my torrents just stop, and then I have to manually disconnect from the network and then reconnect and it works for about a min and then happens again. I couldn't even get enough internet to post this from my laptop so I had to post this at school from a windows. Idk whats going on but it sucks because I cant really use the comp without the internet..

I occasionally stay at hotels where I get free wired internet but not wifi, I'd like to use my laptop as an access point so that I can have internet on my Ipod Touch. I know it's possible because after trying unsuccessfully in Ubuntu 9.04 a few times I decided to try it with windows vista and it took me a matter of seconds and both the laptop and ipod touch were surfing the internet. I'd prefer not to boot into windows just for this.
In ubuntu when I create a new wireless network, network manager shows that I'm connected to both the autoeth0 and the wireless network I created but neither computer has internet access.

I have a laptop with Ubuntu 9.10. And I want to connect it to Internet using wifi. Also I have desktop with Ubuntu 9.10 (another desktop with Win XP, but for some day it will run under Ubuntu too ). I want one of this these desktops to share wifi with laptop. I think that a wifi adapter is a way to solve this problem. I found a D-Link dwa-110. i've read on forums that someone successfully installed drivers [URL]. Is there any other ways to share wifi with laptop (only 1 laptop needs to be shared with)? Had someone connected desktop with D-Link dwa-110 and laptop (as I want)? Both desktops connected to Internet via wire.

I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

Running 9.10 Ubuntu on my laptop. It connects fine to regular access poitns, but for some reason it won't connect to my android wifi adhoc sharing. I have it as dual boot with Windows and windows connects to it perfectly. From Ubuntu 9.10 it tries to connect... then just disconnects. Would be killer to be able to use it with my adhoc wifi sharing! I prefer my Ubuntu boot, rather than my windows one

I have an Ubuntu laptop connected by wifi to a Cisco router and a desktopUbuntu PC conneted by wire to the same router. I would like, if it's possible to connect them without using the Internet (I mean what I want it's not just communicate between them using SSH over the Internet, for instance, but also communicate without connecting to the Internet). My DSL connection it's 4 Mb/s while my router can work up to 100 Mb/s so I would like to take advantage of these 100 Mb/s to transfer files between the two computers instead of using 4 MB/s

I have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behaviour when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information.
