Ubuntu Networking :: Wifi Card Rtl8172 Not Working When Laptop On Battery?

Feb 24, 2010

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.

Ubuntu Networking :: No Wifi/ethernet After Battery Died While Laptop Was Asleep?

Jan 10, 2011

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?

Ubuntu Networking :: Broadcom Laptop Wifi Card Driver?

Mar 9, 2011

I have an emachines D620 laptop running Ubuntu 10.10 with a Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01). I havent done anything with it and cant seem to get it to work. I know this because when I had visto on it the card worked, but know it says that its firmware is not enabled and ive tried installing the drivers using the Additional Drivers under Administration. I would like it to be working so I can use my laptop's internet.

Ubuntu Networking :: HP G62x Laptop - Ralink 5390 Wifi Card Does Not Work?

Apr 29, 2011

I recently bought a HP g62x laptop for myself. It sports a decent Core i3 processor, 4 gigs of RAM and a 500GB HDD. It also came with Wireless-N, a real bonus because I am using a Wireless-N router. The chipset is a Ralink 5390. It came preinstalled with Windows 7, and everything works fine in there (obviously).

I then proceeded to install Ubuntu 10.10 x64 a few days ago (this is before Natty came out) and everything worked . . . except WLAN. So I plugged in via Ethernet and went looking and found that I clearly wasn't the first to discover this issue. I found a guide here that I followed to download the Ralink Linux driver (which is stated to support my chipset), configure, compile, and install. Everything went perfectly, I restarted; lo and behold, I have a list of access points. I went to connect to mine, entered the password, and now the animated "WiFi wave" logo keeps going indefinitely until you click it, and it freezes for a few minutes. It will unfreeze if you let it sit but clicking it causes the same freeze again.

I couldn't really care less about a WiFi icon freezing, but a.) it freezes everything else in the system up, not just the icon, and b.) it never actually completes the WiFi connection. I really, really don't want to be forced to use Windows because of a crappy WiFi driver!

Since Natty came out I installed that and I can't even compile the driver without fatal errors, so I reverted to 10.10 and everything is the same as it was before. Note that this is a clean Ubuntu 10.10 Desktop Edition 64-bit install, nothing updated/modified/changed besides (attempting) to install this driver.

Ubuntu Networking :: Edimax WiFi Card Not Working With Karmic

Jan 7, 2010

Finally took the plunge and upgraded my ubuntu studio to karmic from jaunty. I seem to be experiencing a problem many have, being that my wifi card (edimax) which worked on my previous distro is now not working at all. I've done a lot of research and found the problem seems to mainly be with broadcom cards, and have tried a number of things relating to those that have worked for others, with no luck.

My problem seems to be not that the drivers wont activate or anything like that, my problem is that under hardware drivers nothing appears at all. I have no drivers present, where most people are talking of 3. i have not found anyone else with this problem. My problem is compounded in addition by not being about to use a wire connection at all.

Ubuntu Networking :: Atheros 9k WiFi Card Not Working After Suspend?

Jun 25, 2010

I am currently using Ubuntu 10.04 Lucid Lynx. Although it has worked fine for the past couple of weeks, I have recently encountered a problem with my wireless card. It is an Atheros AR928X card on a Toshiba satellite U405D-S2874 model laptop. Recently, I attempted to put the computer into suspend mode for the first time. The computer failed to wake up, and I performed a hard reboot. After this, everything seems to work except for the wireless card. I am now unable to connect to any wireless network with my laptop, and the wireless manager doesn't seem to be working either.

Ubuntu Networking :: Intel WiMAX/WiFi Link 6050 Wireless Card Not Working?

Dec 14, 2010

I'm dual booting windows 7 64 bit and Ubuntu 10.1 64 bit on my Dell Inspiron 11z with an embedded WiMAX/WiFi Link 6050 series wireless card made from Intel. I only use it for wifi, not 3g or wimax. I installed the latest driver from intellinuxwireless.org, iwlwifi-6050-ucode-41.28.5.1, but it still doesn't seem to work. I ran these terminal commands from another thread:

cd Desktop/wlwifi-6050-ucode-9.201.4.1
sudo cp iwlwifi-6050-4.ucode /lib/firmware
sudo chmod 644 /lib/firmware/iwlwifi*

[code]....

After running "sudo rmmod -f iwlagn sudo modprobe iwlagn", I get this read out for my wireless card.

*-network DISABLED
description: Wireless interface
product: WiMAX/WiFi Link 6050 Series
vendor: Intel Corporation

[code]....

In the ubuntu help section it tells me to flip a manual wifi switch to enable it, but pressing my windows wifi button, F2, doesn't appear to do anything while in ubuntu. The only experience I have working with linux is typing some terminal commands on my android phone to root it.

CentOS 5 :: Laptop Automatic Shutdown On Low Battery Not Working

Aug 28, 2010

I'm trying to make my system automatically shutdown once the battery level is low, but still without success. I've tried kpowersave, gnome-power-manager, kpower, klaptop but none of these worked for me. Well, I can't imagine I would be that stupid, but simply it doesn't work. In all cases mentioned above (kpower, klaptop, gnome-power-manager) I've tried to setup the laptop to shutdown once the defined level is reached, but the laptop never actually switched off unless all the battery was drained.

Btw. I think all the above mentioned apps only work once the user is logged in. But I'd like the solution to work also when the PC is on without anyone logged in. I thought I could write a bash script based on parsing of acpitools output and define it as a service, which would monitor the battery level, but I simply don't believe there isn't any functional solution to this.

Ubuntu :: Laptop With No Battery - Checking Battery State

May 1, 2010

Just installed 9.10 followed by a 10.04 upgrade (wouldn't work as a 10.04 clean install). The install and upgrade all seemed to go well.

But now when booting I get a message saying "checking battery state" and then it boots no further. This is a laptop without a battery installed, running permanently from the mains through the charger.

How can I disable this check so that the laptop will still boot without a battery fitted?

Debian Hardware :: Lower Laptop Battery Charging State To Prolong Battery Life

Mar 2, 2010

getting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactionsĚ and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.

Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery MaintenanceĚ utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.

I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.

Debian Hardware :: WiFi Card Not Recognized (Laptop HP 430 G2)

Sep 12, 2014

I'm a brand new user of Debian, and I just bought a (too much?) new laptop, the HP 430 G2. It seems to work great for almost everything, except that I don't have any wifi available.

I tried so many different things (without any success) that it would be hard to resume. But for now, all I have is a new installation (to avoid parasite installations of weird things), and a kernel updated to 3.16. I don't know if it's useful though...

Some information from my system :

Code: Select allbonyhoax@bonybook:~$ sudo ifconfig
[sudo] password for bonyhoax:
eth0      Link encap:Ethernet  HWaddr 14:58:d0:09:72:bd 
          inet adr:130.125.57.144  Bcast:130.125.57.255  Masque:255.255.255.0
          adr inet6: fe80::1658:d0ff:fe09:72bd/64 Scope:Lien
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:27329 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3491 errors:0 dropped:0 overruns:0 carrier:0

[Code] .... 

The first element I notice is that I don't have the line with "Kernel driver in use...". Which seems to indicate that there's a problem with the kernel module (is that right?). But I don't know how to fix it...

The other thing that puzzles me with these last two commands is that according to this page, my wifi card is a Broadcom BCM43142. But it's not the result I get with the lspci command.

Anyway, I'm really lost, I don't know what to do, what to check, what to install. I don't want to go by random, testing all the different solutions I see on the web blindely. This is the reason why I ask it here.

Ubuntu Networking :: Intel 5100 WiFi Card - Dell Latitude E6400 - Suddenly WiFi LED On The Computer Stops Blinking

May 4, 2011

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.

What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.

On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.

My exact hardware:

I notived the following problems in /var/log/kern.log

Ubuntu :: Battery Not Recognized On Laptop (and It Recognizes Laptop As A Desktop)

Apr 15, 2011

I have installed Ubuntu (both 10.10 and 11.04 pre-release) on my laptop but my battery is not recognized and it is detected as a desktop system rather than a laptop. I have tried the cat /proc/acpi/battery/BAT1/state method but the directory doesn't exist. I have tried another guide to paste the battery info into this directory but it doesn't allow me to do that and says that the directory doesn't exist, even though I'm trying to make it. I tried it in root nautilus and even on an install of Lubuntu (with a root file manager) but it still failed to budge. I really don't know what to do as I have tried all the guides on the internet that I could find.

Debian Hardware :: WiFi Card Not Working

Dec 6, 2014

I have some problems with my WiFi card I'm configuring for Debian Wheezy. I've used it in other computers successfully (It's a USB device), but this box doesn't seem to be able to recognize it or use it properly.

I've identified the card using Code: Select alllsusb with the output Code: Select allBus 001 Device 002: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

I've used the Wheezy docs to download the firmware necessary and it apparently is supposed to run fine with this firmware, but nothing is working. There was mention to a GitHub repository of a fixed version of the driver in question, which didn't work either.

Fedora Hardware :: Either Working WiFi Or Sound Card (Not Both)

Jan 20, 2011

With my Compaq CQ62 it seems I can either have a distro provide a working wifi or a working soundcard but not both. I would love to have Linux working properly. Wireless internet works great in Windows 7. The ethernet works perfectly when I plug directly into my router, but pressing the wireless button will not change the light on it from orange to white or do anything else. Yet a simple distro like crunchbang or kubuntu seems to make the wireless work fine.

They just cant make my soundcard work. Being that there is at least some sort of a protocol for installing wireless drivers, I figured I would go with the distro that gives me SOUND since installing a sound driver seems unheard of or impossible. I have a realtek wireless network card in my laptop that Fedora, one of the biggest names in Linux, seems oblivious to even recognize. When I click on the network icon and go to Manage Connections, the Wireless tab is greyed out and cannot be clicked on.

Ubuntu Networking :: Use Laptop As Wifi Hotspot?

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.
