Ubuntu Networking :: Wireless Connection Dropping Out But Still Showing It Is Still Connected?
Jan 20, 2010
as the titles states my wireless is dropping out but the networks manager is still saying i have a connection. the only way i have been able to be on the network every minute or so i have to manauly disconnect and reconnect to my wifi. under my windows 7 and vista installs the wireless card works fine now my card is a dlink dwa-547 and it uses the arthores chipset, it is encprtyed wifi, wpa2 aes on a n/g based network
Code: Network controller: Intel Corporation Wireless WiFi Link 5300 I have Ubuntu 10.04 32bit installed:
Code: Linux dani-laptop 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC 2010 i686 GNU/Linux
It has been working fine since I installed 10.04 but recently (end of last week I think) it stared dropping the wireless connection very often. So it will disconnect and reconnect, but I can't seem to find a pattern, sometimes it goes for hours without an issue and sometimes it does it several times in a row. Below is an extract of syslogs from when this happens. But not sure if what I need is there... the only weird thing I can see is:
Code: Oct 27 18:58:32 username-laptop wpa_supplicant: Trying to associate with 00:1e:be:a6:c0:0f (SSID='accessp' freq=5280 MHz) Oct 27 18:58:32 username-laptop NetworkManager: <info> (wlan0): supplicant connection state: completed -> associating Oct 27 18:58:32 username-laptop kernel: [123835.372217] wlan0: deauthenticating from 00:1e:7a:6f:d9:90 by local choice (reason=3) ..... Oct 27 18:59:29 username-laptop ntpdate: no server suitable for synchronization found
Sorry if this has already been solved;answered anywhere else - I tried looking it up but to no avail. The problem persists & the hints I found around the forum did not provide a solution to the case, neither other net solutions i looked up I run Winblows at the lab and sometimes take my Ubuntu PC with me. There is an open Wireless network where they set MAC permission, and there's no pwd to access. It so should be fairly easy to change m MAC and access it, right! No. I run ifconfig and macchange, successfully change my MAC addr BUT the connection drops! Then if I change it back (MAC to my original address) it goes back online. And yes, I shut down the service -- "ifconfig wlan0 down" and then up..WHAT ON EARTH am I doing wrong??? No webpages touch this 'trouble-frigging-shooting instance!
I have a Dell Inspiron 6000 laptop running Fedora 12. Recently my wireless connection has begun dropping every few hours and not reconnecting. After trying for about 30-45 seconds, the WPA password prompt comes up but still doesn't connect.
Fedora release 12 (Constantine) Kernel Linux 220.127.116.11-67.fc12.i686 GNOME 2.28.2 Memory: 2.0 GB Processor: Intel Pentium R 1.60 GHz
When I turn on the computer, it connects to wireless automatically. That's good. But it doesn't stay connected very long. Especially if I turn on a p2p program or make a call through messenger. Then I get disconnected suddenly and if I want to connect again it doesn't work anymore. Network - You are now disconnected and that's it. Every time it happens I restart the system. I use an Acer Aspire 5738z laptop.
Ubuntu 9.10 working great. Installed Orange 515m as per fix shared on this and other forums; however while it works great at home, it will only 'connect' once at work - on subsequent attempts it connects, but browser etc behave as though they cannot find the modem and I cannot make further connections via gmail and Firefox. I had just made the swap from Win 7 to Ubuntu 9.10 for work as well as home, but I cannot be in the position of being unable to access my emails and so swapped my hard drive back to Win 7 drive today
Just installed kubuntu 10.10 on a dual boot with winxp on my asus r101 netbook. wireless connects perfectly, but after roughly 30 seconds, i cant access any address or ping an url or ip. however network manager says im still connected. so i click on network manager, and click on the wireless connection, it then reconnects in a couple of seconds, and all is good again. i carry on browsing, and 30 seconds later the same happens again!!! my wireless signal is fairly week, however connection works everytime and in xp this is not an issue.
After entering the command I have lost all ability to even use my wireless ability even if it was for 5 minutes. Now I am using a different kernel, internet still drops every 5 minutes, but would love to get my internet up and running again.
I'm using an Acer Aspire 3000 since Opensuse 9.3. Wireless connection was fine with ndiswrapper. I upgraded to 10.0 and wireless was perfect with the broadcom firmware. Now I just installed openSUSE 11.3 and my wireless connection became a nightmare: connection drops multiple times in a day and network manager remains stuck in "Interface Configuration". Sometimes I'm asked for the wpa password but Network Manager is unable to reconnect until I disable and re-enable my wlan card using the killswitch. The access point is the same zyxel b+g I own since 5 years! I just bought a new eeepc and I installed on it openSUSE 11.3 too. The network connection behaves the same!! The Network Manager says "Interface configuration" and I must switch the wireless off and on to have the network back. I made a radio scan and I'm using a channel on my own. I also tried to disable dhcp without success.
I am having an issue with my wireless connection dropping about every 2 minutes (web pages timing out), then working for a couple of minutes then dropping again. The connection icon in the task bar says I'm still connected at about 70%.I have a dual boot system and the wireless works fine in opensuse but not in Ubuntu 10.10 I have an Asus G50vt-X5 laptop but I am not sure about the wireless chipset.
Toshiba A215 laptop Driver is rtl8187 I really need to make the connection constant and non-dropping. I've had opensuse 11.2 since march 7 2010, figured out most of it by lurking and reading threads didn't want to make threads but I really don't know what to do to make this connection stay on. I am posting Terminal commands from when I am both on and offline.
How I attempted to fix this issue myself: I downloaded wireshark, wicd,knetworkmanager. Tried running all of them nothing worked. I went into Yast and switched off networkmanager and went traditional still nothing. Tried adding opendns to traditional. nothing. Went back to NM would get online then after an unknown time I'd lose connection even though NM said i was still connected. Offline running terminal commands from what I read on here in other threads and stickies

using Hardy Heron on a old Thinkpad T41.This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time. fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..

In summary, I am using openSUSE 11.2 x64 on an Acer laptop with a wireless AR928X card. I can connect to my WEP-secured network when I boot up. After some time (it might be minutes, it might be hours), I am prompted for my WEP password again. This never works, despite being the one which gets me on-line at start-up!. The only solution is a reboot. The problem is intermittent and doesn't seem to depend on my on-line activity. I have tried the following with the same result: KNetworkManager Traditional using IFUP Enabling / disabling IPv6 support
I tried installing the compat-wireless package through YaST and then managed to get no internet connection at all. Went back to KNetworkManager and things "worked" again until I was prompted for the WEP code. I have openSUSE 11.2 x64 working on my office laptop without problem and can connect to my home network without any problem. My issues are with my personal laptop. I have reached the stage of booting into Windows 7 as my default option so that I can access the internet reliably. What I can do to diagnose and repair the problem - could it be that the card is going into powersave mode? If so, how do I stop that happening? I'd prefer to be on openSUSE but need to be able to rely on the internet.
Using Wicd and it keeps dropping out or telling me "bad password" when the password is in fact correct. I even know it works because the first couple of times it worked, but the connection wasn't sustained for more than a few seconds each time. My reasoning is my wireless is functional in Ubuntu, there's no reason it shouldn't be in Debian. Wireless network card is ASUS PCE-N13. Ralink driver is installed. WPA-supplicant is installed. Gnome Network Manager is also present, though I've heard that it doesn't support my particular situation.
I am running 64bit 10.04 on my Dell Latitude D620 with a BCM4328. The hardware drivers are working and I can connect to my wireless network but...The annoyance is the wireless icon in the task bar does not show a connected status. Instead I get a grayed out icon with a red exclamation point over it. I am connected though.
Lately I have been using my window's partition due to the fact that 10.04 drops my wireless signal every 5-10 minutes, but today I downloaded the new updates and that seems to have fix the issue with the dropping of the wireless connection. Now the only problem is the internet is so slow when trying to go to webpages it times out. I have opened up firefox gone to about:config and changed the necessary lines, but still dreadfully slow.
I have a windows installation (partition) but have installed into freespace on the same drive using the auto-partition manager, etc, and everything is fine. I got my network going fairly easily by going Preferences > Wireless and inputting SSID and WPA encryption key (PSK). My router issues an WLAN IP, I can get on the net, I can see my other Windows PCs on the network, I can reach my router, and all is good.So after several hours of mooching about and looking at things, I have updated all the Linux packages via Synaptics (following a prompt to update everything) including GRUB. My dual boot now shows two versions of the OS:
GRUB 1.7~Beta4 Ubuntu, Linux 2.6.31-19 - generic (I am booting this one) Ubuntu, Linux 2.6.31-14 - generic
I also set up my HP F4580 printer over wifi on the network though with slightly incorrect drivers (for the F4400 series as this was recommended at the closest match). It works, and I can print a test page no problem.The only thing is that now (since doing all that) Ubuntu seems to periodically drop my connection to the network and then request the network PSK again, but when I enter it, it spends time trying to renegotiate but fails, and then re-requests the PSK, over and over and it never reconnects. I have to reboot and then I can connect again (automatically), until it drops at some random point (like 5 or 10 mins later)
Two weeks ago I decided to ditch my XP install completely and switch to Ubuntu 10.04. So far so good, and I'm very happy with my decision. However, about 3 days ago, my wired connection started playing up. It keeps dropping out every 2 hours or so between 13.00 and 04.00. After dropping out, it immediately reconnects again (at least when I use Automatically DCHP config). From 04.00 to 13.00 it is more or less stable.
I tried resolving by reserving an IP in the DCHP Client Table in my router (linksys WRT120N). Additionally, I told the Network Manager to use the Manual configuration. Unfortunately these changes didn't help and the problems stay the same......
The daemon.log shows the following information code...
I've just loaded the new Hamachi2 Linux beta with Haguichi for a GUI. Everything installed & connects OK, but the connection at the hub is dropping & reconnecting every minute or so. I tried adding a line to the sshd_config file to keep it alaive but it didn't make a difference.
Here's the situation: I've got an eee pc 901 running Ubuntu 9.10 netbook remix. I'm using it to connect to a WPA-encrypted wireless network on a WRT54GL running dd-wrt. It mostly connects and works ok, but sometimes it just stops working for no apparent reason (the netbook still shows itself as connected), but you can't get anywhere until you manually disconnect and reconnect. Other times, it will drop the connection, and then quickly reconnect (or sometimes not). Obviously, this behavior is pretty irritating. At first I thought the problem was with the router, but I checked the logs there and they all seem fine, and other computers on the same router don't have this problem. Looking at "dmesg | tail" on my netbook, I see a lot of instances of the following error, which I'm thinking is probably the problem:
I searched for that error message and I found this Ubuntu bug report: [URL] that describes symptoms that match mine. In that report, a poster mentions that he compiled and installed a new version of the wireless driver from the Ralink website, and it fixed his problem. Do you think installing a new driver would be good? Or has that updated driver already been added to the kernel since that bug report was filed? I've never compiled a kernel module before.
One other thing, I also see repeated instances of these lines (or similar ones) in dmesg, which look like they could be related.

I am running F13 on my Desktop (with a Ralink RT2870 wireless card) and also on my Laptop (Acer Aspire 5738Z) and am connecting to the internet via a NetGear router. On my Laptop I can connect to the internet fine with no problems. However on my Desktop when I turn my computer on it connects to the internet fine, and works, however after some time (maybe 5-10 minutes) it disconnects and the box asking for the password reappears, then I click connect but no joy.
The connection box just keeps reappearing and it won't connect again until I restart the computer (although sometimes it takes more than 1 restart!). This is not a signal issue, as my Desktop also has a Windows partition and that connects to the internet fine and does not drop off. I have installed the RT2870 driver through rpmfusion, which didn't fix the problem, although uninstalling the driver didn't stop the card from working.
I usually start up my Internet service by typing ./rc.inet1. While its connecting I usually see my routers ip address then I connect and I start browsing and everything is fine. A few times I noticed that instead of seeing the routers address it showed some other address and I could not get online. I try ./rc.inet1 stop and renew but still cannot connect, I reboot and I then see the router and I can connect. I am using slackware13, and opera10 browser.
This is weird. I will be working on the internet with several tabs open and all of a sudden the pages won't update. I can't go anywhere - it's like I lost the connection. I am also downloading bittorrents with uTorrent running with WIne and that doesn't seem to be affected. I also have gPodder and I tried to update podcasts with that and it also hangs up as if it can't connect. The only way I have been able to solve this has been to reboot (which I just did).
Having major wireless issues with Linux. I have DSL and had a Westell router/modem combo and my wireless would stay up for no more than 15 mins at a time even while idle, and in order to get wireless back I have to reboot and then I can get another 5-15 mins of wireless before it drops. When it drops it prompts me for my wep key and wont accept it yet if I reboot it catches the wireless right away for a very short period. So I go out today and spend over $100 bucks on a Netgear dgn2000 thinking it would fix the problem... Nope I am still in the same boat as I was with the Westell.
I am not seeing my router model listed under the wiki link sticky.. (Edit) thought I installed ndiswrapper, it was it was in my downloads anyway I can't install it I get the following error (Not a valid driver .inf file.)I have tried 3 distros and have the same problem. I went to Netgears site in search of Linux drivers but all I found was the firmware updates. Could some one please shed some light on what I need to do to get up and running?This is a new laptop and I am pretty annoyed with myself for formatting it out of the box rather than reading up a bit more about Linux (been using for one month).I don't understand it Ubuntu 10.9 ran wireless perfect on my older system, (full install) and I have no trouble with my lap top that is running Windows.I really hope to get this resolved I really enjoy Linux and I don't want this to be the one handicap which would force me back to Windows, that would be very upsetting
I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).
However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?
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]
As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

When I try to connect a projector to my laptop (already running) and hit the fn+f7 (the designated button for switching screen), nothing happens. I see "no source found" on projector screen and my laptop screen works perfectly. Now if I restart the laptop with the projector connected, I see all the intial booting messages on the projector screen (not on my laptop), then the gnome login screen appears on both the projector screen and laptop (when the login screen appears on laptop it looks like it has lower resolution than my usual laptop resolution). But immediately after I log in, my laptop screen goes blank, and projector screen becomes the only active screen.
If I restart without the projector, again all normal operation on laptop screen is restored.
I feel like I am missing some very silly options. Any help is appreciated.
Here is the output of xrandr when the laptop is connected:
