Ubuntu Networking :: Wireless Auto Reconnect After Power Savings Mode?
Aug 17, 2011
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 have my openSUSE 11.2 connected to router by wifi. I want frequently to access it from my LAN or even Internet, but even so frequent the connection is lost for some reason.
When I am at the box, I can easily do a ifdown/ifup and it will reconnect, but that is a pain when I am not local.
is there some way or maybe a script to check the connection so now and then and if not online then re-connects it automatic ?
I'm having problems trying to turn on the power saving on my intel 3945ABG wireless chip with the iwl3945 module. if i remember correctly, i used to be able to have the power levels adjusted before with previous releases / kernel (i started caring about power savings back again after getting a new battery).
keying 'iwconfig wlan0 power on' returns Error for wireless request "Set Power Management" (8B2C): SET failed on device wlan0 ; Operation not supported.
And 'iwpriv wlan0 power' returns wlan0 no private ioctls
Is there something i'm missing or does the chip/module doesnt support power saving features?
I'm having a problem with the wireless on my Asus EEEPC 1000HE using Ubuntu 110.04. Digging into the laptop forums, it says there is a problem with wireless on some models of the 1000HE, but it is not the same wireless device and my wireless problem doesn't seem as bad as listed, so I think it's a different problem. But my problem is that if wireless drops for any reason, it will not start working again unless I either reboot the computer or click the wireless icon in the systray, click disconnect so it stops flashing (like it's trying to reconnect) and then suspend my computer or log off and back on. And it only does the latter because I added a file located at /etc/pm/config.d/00sleep_module with the one line that reads SUSPEND_MODULES="rt2800pci" (my wireless driver) So that one line seems to cause wireless to get a fresh connection after suspending (or something. I'm not a very advanced LInux user). I've tried running the command "sudo/etc/init.d/networking restart", but that does nothing for me. I'm not sure what other command to try to see if can fix it.[URL]
I am fairly new to linux. I have Ubuntu 10.10 on my Dell Inspiron E1705. While browsing my internet connection suddenly stops working. It says that I am still connected but the internet doesn't work. When I try to disconnect then reconnect it will not connect to the network. To get it to reconnect i have to turn of the wireless card, delete the connection then restart, turn the card back on and reconnect.
Running 10.10 on Hp dv2000. Approx once a day wireless asks for password authentication but cannot re-connect to wireless network. I verified connection, correct password and modem & router functionality but still will not re-connect. After re-boot problem is resolved for another day or two.
Sometimes I am unable to reconnect to my wireless AP using the same settings that worked the previous day, and that has me stumped. I think it's due to me switching access points (using different authenticatin) since the last connection.
1) After I enter iwconfig/iwpriv commands to connect my wireless usb card (edimax) to my WPA2 network, what process performs the negotiation with the AP, and is there a way to see status debug messages from that process so that I can see if there was a successful negotiation? (so I can see if the password is correct, etc).
2) Is there a way to manually invoke that process to re-attempt to negotiate? Or must I assume that happens automatically with any iwconfig/iwpriv command?
3) Is there a simple command that will erase all iwconfig/iwpriv settings so that I can start over with my iwconfig/iwpriv commands?
i cant get Qinternet to auto reconnect when connection is lost due to dynamic IP changes from my ISP.Im using Ifup method.Thing is, every 24 hours, ISP changes my IP and thus, disconnects me from the internet. I need it to reconnect but dont know how to do it.
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.
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 done a clean install of debian 8.2 (jessie) on a new PC. I am working through some of the issues that were not correctly installed. One of them is the wireless network. On startup, I have a wireless connection. At some point within the first 5-25 minutes of being logged in and doing computer stuff (there is no known action that leads to the reaction), the wireless disconnects from the network and will not reconnect. The network-manager-gnome shows three horizontal dots; the system settings> network shows all of the available networks, the strength of their signal, and the "connecting" circle spins. This behavior occurs with both WPA and insecure networks.
I have followed the guidelines for Debian>WiFi>HowToUse (https://wiki.debian.org/WiFi/HowToUse). Nothing appears amiss when following the Network-Manager>Gnome portion of the instructions. I was going to try the alternate WICD program, but one has to uninstall network-manager to use wicd and synaptic also wants to remove something called "gnome", too-- uninstalling a package with that name makes me uneasy. I have noticed that the installed versions of network-manager (0.9.10.0-7) and network-manager-gnome (0.9.10.0-2) don't exactly agree, but I doubt that that is significant.

I am using a Linksys wpc600n wireless card that works fine in windows xp, but will not even power on in ubuntu. I tried to use the pccardctl command to get the card to turn on but it still does not turn on.
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.
my wireless will connect to a well known connection but will sometimes drop the connection then tries to reconnect. Sometimes it will reconnect w/o a problem but most times it will fail and when it fails it will refuse to even recognize that same wireless connection.
If by a small chance it does recognize the network then when you click on it, it will ask you again for the password, which is already saved onto the computer. After entering the password it will try to reconnect, then fail.
Only solution is to reboot.
I was wondering if there was an easy temporary fix of just reloading the software that controls the wireless.Such as, my audio doesn't work when I boot. I need to reload the ALSA driver using sudo /sbin/alsa force-reload
Is there something specific to the wireless that I can force-reload and it will start working w/o having me reboot my PC?
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
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 have problem with my wireless GSM connection , my notebook has built-in Toshiba (in fact Ericsson) F5521gw wireless modem , it is detected and usable by default without installing additional software.Problem is that I can connect flawlessly only once after switching on notebookif I disconnect manually I'm not able to connect again, i have to reboot my computer or another solution which allows me to reconnect is closing and opening lid (putting notebook in suspended state)I'm using Toshiba Tecra r850, openSUSE 11.4 x64 on Gnome 2 DE, using NetworkManager and nm-applet /var/log/messages after using disconnect from nm-applet:
Code: Sep 8 17:04:39 linux-b5nl pppd[9933]: Terminating on signal 15 Sep 8 17:04:39 linux-b5nl pppd[9933]: Connect time 243.2 minutes.
I've started using slackpkg to keep my system up to date now and after the updates in January my wireless doesn't reconnect after a resume from suspend, I have to connect then kill dhcpcd and restart it. Any ideas what changed there and how I fix it. From the install of 13 until Jan it worked fine.
left to its own devices my wireless connects at too low a speed. I have a 20meg internet connection and my wireless is slowing it down to like 3meg. When I reboot into windows it's fine. When I run iwconfig eth1 rate 11M or even 24M the connection is much faster and runs fine, why won't it automatically go higher? Is this the fault of the driver? I am running Broadcom's driver compiled from source. Also, how can I set it to 24M at boot?
Edit: I guess I can put iwconfig eth1 rate 24M in rc.local, but I'd still like to get auto running higher, especially as my signal should be pretty good. Output from iwconfig white rate=auto:
eth1 IEEE 802.11 ESSID:"honeypot" Mode:Managed Frequency:2.417 GHz Access Point: xxx Bit Rate=1 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thrff Fragment thrff Encryption keyff
I've been trying to get and old PCI wireless card to work on Ubuntu 10.04. The card is a Zonet 1602. It was not recognized automatically.
I have been able to get it to work using ndiswrapper except that when the computer is started it does not automatically connect to the network. I can click on the network icon and select my network from a list and it will connect, including properly authenticating the network key.
I have worked through a lot of information on the web but much of it seems to apply to earlier versions of Ubuntu and some if it does not match what I'm seeing in 10.04.
There is a built in Ethernet controller on the mother board but I have disabled it in the BIOS.
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. uname -r
I am trying to figure out why, i need to restart/reboot ubuntu in order to reconnect wirelessly after being in power save mode. It works fine before the power-save mode and fine after the restart. Is it an IP issue?
I recently installed Ubuntu 10.10 onto my Acer Aspire D260 netbook.I find it much easier to use than Windows 7.Everything has been working fine until I recently tried going on the internet via battery power instead of my A/C charger. My update manager is showing that I am up to date and Additional Drivers is showing that the Broadcom STA wireless driver is installed and in use.
I found an application AUTO POWER ON & SHUTDOWN in windows which is really very useful to those who have night unlimited broadband connection. I searched for similar application in UBUNTU as I am slowly shifting to UBUNTU from 10.04 (maveric) version. Whenever I search for application or for other options, so many have written failed attempts only.
I can't get my wireless into monitor mode. I;m running ubuntu 9.1 karmic It connects fine to wireless networks. But when i do: sudo iwconfig wlan0 mode monitor. I get: Error for wireless request "Set Mode" (8B06) :SET failed on device wlan0 ; Device or resource busy. I can only see wlan0 (wmaster0, eth0), not ath0 or wifi0 mentioned elsewhere, in wireshark. I only see my own ip and packets coming to and from that. my system tells me i have an atheros ar9285 chipset in place.
