Ubuntu Networking :: Wifi Keep Disconnecting In 10.04?
May 19, 2010
I never had this problem with Ubuntu before and I am now confused. This is a clean install and I have not change anything about my AP so don't why this is happening.
Every 5min or so my wifi keeps disconnecting and sometimes have problems reconnecting. I also have Windows on this machine and it does not do this at all. My AP is set to channel 9(changing it makes no difference), WPA2. Logs below

[ 15.668748] alloc kstat_irqs on node -1

Its been like this since fedora 12, in fedora 11 its no problem, i hope it will be fixed in fedora 13 and i am waiting..., and after fedora 13 released the problem is still the same...
I use Intel 3945ABG. wifi connect with no problem and after few seconds its disconnected, and re-asking my saved password (which is stupid since i save the password so fedora won't ask me that stupid question again).
I'm running Ubuntu 10.04 64bit on a 15' Dell Studio After doing an update my internal wireless will not connect to my wireless network. The card is on, I can see networks around me, but it will not connect to mine. It just acts like its connecting and then disconnects.
-i have a HP Pavillion dv6 entertainment pc laptop -im using ubuntu 10.10 -my wifi indicator keeps flashing -before when i was using fedora this was not happeneing -and now some times in between wifi disconnects and doesnt connect back -only after restarting it connects back -anyway its not disconnecting very frequently -but when i put something for downloading in the night, morning i can find it incomplete as wifi got disconnected -same time my netbook using windows xp keep working and connected
Using a USB ISO, I recently installed Debian 8.0 Jessie (64-bit, Xfce DE) to a new computer. I usually lose my Wifi connection after 1-3 minutes when donwloading/uploading at around max. speed 4 Mbps/512 kbps. Sometimes it will last 15+ minutes.
When lightly browsing it can usually stay connected for 15-30 minutes. I have to disable and enable Wifi using NetworkManager to connect again. If I remember correctly, there were problems with the Wifi connection even during the installation of Debian.
This Wifi USB adapter works fine on my old computer with Debian 7.7 (32-bit). No problems with the Wifi connection yesterday on my old computer during 10+ hours of activity.
This Wifi adapter also works fine on this new computer when I boot from a live USB (Rescatux 0.30.2) downloading and uploading at max. speed for 1+ hour.
I already tried some suggestions I found online, but they didn't work:
* changing Wifi channels between 1, 6, 11 in my router settings * changing WPA-WPA2 to WPA2 in my router settings * ignore IPv6 in NetworkManager * change probe_wait_ms from 500 ms to higher value by adding Code: Select alloptions mac80211 probe_wait_ms=1000 or Code: Select alloptions mac80211 probe_wait_ms=3000 to /etc/modprobe.d/mac80211.conf and rebooting * disable Power Management for Wifi adapter (not supported) * ...
I can also post the output of commands from Rescatux or my old computer if needed.

I have recently purchased a cellular usb modem, a ZTE MF637. To my surprise and pleasure the device worked (almost) out of the box (almost, because I had to supply a user name and password to the wireless broadband connection properties).
Anyway, the problem is, that the connection work fine, but only for 20 minutes or so (I did not actually measure it), then I experience 0 network activity, and shortly after that the connection drops, and the device is no longer recognized as wireless broadband.
What I do is remove the device, replug it, and after a minute it reconnects. until the next drop.
I'm using Lucid on an Asus eee 1101HA.
Oh, one more thing, in lsusb, the device is listed as MF636, but the box reads MF637. I don't know if it matters, but there it is.
I have always had trouble in the past getting wireless adapters and what not to start working on Ubuntu but with each 6-month upgrade most problems are fixed while new ones are made. Since Ubuntu 10.10 just came out I thought I'd give it a go and test it with my hardware.
Before 10.10 Ubuntu could not connect with my wireless device and I had to do many things with gedit and such to get it working. After I have upgraded to 10.10 Ubuntu now recognizes my wireless device and network and I can search the web...but wait here it comes.
Literally minutes after a fresh install and first connection to my network my wireless signal will drop and prompt me to reconnect. Of course the first thing comes to mind I reconnect which doesn't work so I unplug the device and replug it making it works...Two minutes later my connection drops again and so I so reboot, and if you really want to know what happens next just restart this paragraph.

i installed ubuntu 10.10 remix netbook edition on hp mini 110 last day. my wifi is working fine its connecting every network only problem is it cant keep its connection constant, i mean it keep disconnecting frequently. once it disconnect i tried to connect again but it connects but i can not surf internet.
I have a Toshiba Satellite M55-S325 (as it came from the factory, no mods), a Linksys WRT54G router, and Ubuntu 9.10/Karmic with all updates. I've had issues since I upgraded from 9.04/Jaunty to 9.10/Karmic. It did work for awhile (I think a few days), but then it suddenly just couldn't find our wireless network. I reformatted (with 9.10) thinking it had just been a bad install - now I can connect to our network, but it throws me off every two minutes. My roommate (Dell laptop, Vista) has no problems with the internet, and I've visited a friend (in another state) and used her wireless internet without issues (though I couldn't tell you which router they were using). I've gone into our router's settings (with both my laptop and my roommate's) to reset the router or change the security settings, but with no real progress.
I'm currently using putty on my laptop to control my headless server (both Ubuntu 8.04.) I'm running an rsync job that ran all night long and still going all day today so far. I need to restart my laptop, but if I do, I'll break the SSH connection. If I SSH back in, I won't see the same thing (rsync is showing me each file it's copying) that I'm seeing now. (At least I think that's true. Please correct me if I'm wrong.)
So I guess my questions are..Is there some way to restore my SSH session when reconnecting? (So I can resume seeing which file is being copied and - more importantly - when the rsync job (finally) finishes?If not, how else can I know when the rsync job finishes?
I updated Kubuntu from 8.10 to 9.04. After the update, I saw a problem with VPN connections. I am using an mac pro with 2 ethernet ports. Only one of them is connected to switch. I am using a static IP in my local network. The problem is that I lose dns information after connecting and disconnecting to a VPN by KVpns.As I am using static ip, I entered my dns server to resolv.conf file with "nameserver 192.168.128.4". My interfaces file is as follows:
Brand new to linux/ubuntu..Just downloaded the most recent version. Well when i try to connect to my network....it connects...then about 2 min later it disconnects and i have to unplug and replug my adapter.
I installed ubuntu 10.04 a few days ago. And I am running into a few problems wherein my wireless network disconnects and prompts me again for password.
Even when I re-enter it (correctly of course) I cannot reconnect and I have to do a system restart. After the restart, the wireless stays connected but disconnects again after a while and I find myself stuck in this loop.
I do not know if the following is any help, but below I am producing the output of lspci command and a few log messages that I think maybe related to this problem
Here is the output of lspci command
And here are some messages that show up quite often in daemon.log
I installed 10.10 for some days ago, networking was working smooth back then. I use a ethernet cable to connect to the internet.But yesterday when I installed 10.10 on my brothers laptop(he connects through wireless), I began to get these disconnects and reconnects.They just seem to happen random.
I have a MSI netbook, U100, on which I've installed Ubuntu 10.10. This keeps disconnecting from the network, though the applet shows me that the netbook found it. I mention that I have a wireless network and another laptop, with WIN 7, where I have no problems with the Internet connection. I also have a 3G USB modem, which let me connect without problem.
My router is a Netgear router with Comcast, and after going on Ubuntu for a couple hours just doing normal things, the Internet disconnects. Then I have to restart my computer and start everything over again. I check the router and everything seems to be fine, I even unplug everything on the router first (like I am instructed to do so if this sort of thing happens) to make sure that's not what is causing the problem. It has to be the Ubuntu system.
I just bought a new laptop. This one came with win7 home. The wireless works perfect. Today I installed ubuntu 10.4 next to windows. I made a first connection which went easy. But after 30 seconds it disconnects. Then it tries 30 seconds to reconnect. It reconnects and after 30 secodns or so, it disconnects again. It keeps doing this all the time on ubuntu while on windows it works without any problems. This is what sais under the device manager for my wirelesscard stuff:
Intel(R) WiFi 1000 BGN Microsoft Virtual WiFi Miniport Adapter #2 Microsoft Virtual WiFi Miniport Adapter Realtek PCIe GBE Family Controller
I'm finding my wireless connection is disconnecting alot, I never had this problem when I was runnning windows 7. I have tried running wicd client but found it was doing the same, then uninstalled the normal network manager and tried just using wicd but it kept saying bad password and wouldnt connect at all. Even though it would work fine but disconnect alot when i still had network manager on.
I can reconnect to internet after disconnecting (this happens every 3-4 hours) only if I manually poke out and in ethernet cable to network adapter or reboot ubuntu. Even restarting network-manager not helps. My provider provides internet over pppoe. I have "DSL-connection 1" item in network managers gui menu. And that item disappears after disconnection.
pppd runs with following arguments: lcp-echo-failure 3 lcp-echo-interval 20 So where can I change this parameters, where is that configuration file?
I'm using Ubuntu 10.04 32 bits and a Realtek 8185 wireless card. The card worked perfectly fine with WPA for a long time in Windows 7, but on Ubuntu I'm having problems. Using it without installing anything else makes it work for a very short time. It disconnects after a while and I have no other choice but to restart the computer.
Using windows drivers and ndiswrapper doesn't work at all (in fact it makes things worse because it stops recognizing my card at all). Using the linux drivers from Realtek's website is what works the best so far. I had to compile them and install them. But it still disconnects after a few hours if I'm using WEP (and only after a few minutes if I'm using WPA). I looked at other people with 8185 problems in this forum but their solutions didn't work for me.
I'm using Mobile Broadband Connection (Huawei 180), When I plugin my RJ45 Ethernet cable, my Broadband connection is no more. I have no access to Internet. why it happens and How can i establish both connections @ once..?
a while ago, Network manager kept on messing around and disconnecting me etc. I attempted to setup a static network (wired) and since then, everything worked fine. I also have apache running and have had no problems with that. I know there were some apache auto updates this week but I have been doing no dev work. I went to check out one of my local sites to do some work yesterday and there was just nothing happening.
I checked everything with apache, it is all running etc. I have stripped back the conf files to be clean and fresh and netstat is showing apache as listening on 127.0.0.1:80 as it should for a single default site that I have on there now. BUT if I try to ping localhost by name or by 127.0.0.1 I am getting "Destination Port Unreachable" Since I have been trying to fix this, I have been trawling the internet to try and clean up my network setup from scratch (I have also had problems with https sites that has turned up to be the MTU setting on my eth0 interface) but to be honest I am not sure exactly what should be set between ifconfig, route, netstat and apache. should I be able to ping localhost independantly of running apache2 (i.e if it is stopped) or would a successful ping rely on apache working correctly.
This is a fresh install of Ubuntu 10.04 on a Dell XPS M1530. I'm getting very frequent disconnects to my wireless network, despite good signal. I have wicd and nm-applet running side by side, wicd doesn't work by itself and nm-applet won't get a new IP after reassociating with the AP.
Wireless connection is steady in Windows 7, so I'm guessing it's a problem with the driver.
