Ubuntu :: Internet Keeps Disconnecting After A While?
Oct 7, 2010
I'm desperate after logging into Windows again (it's so crap ), but I really have no choice cause my internet keeps disconnecting on Ubuntu after a while. Right now I'm on 10.10 Beta but this problem occured on 10.04 LTS as well (that's why I upgraded, hoping it would stop). I had this problem in Windows 7 as well and managed to fix it by using some program similar to Driver Doctor that locates all the drivers you need and don't have yet. It turned out to be a driver for some Adapter back then.However, I'm not aware of any of these programs designed for Linux and I don't know myself what Adapter drivers I need. Also, back in the day when I was using Ubuntu 9.10 I didn't have problems with internet disconnecting all the time.

kernel 2.6.21.5, GNU (Slackware 12.0). Is there a way to disconnect my machine from the internet? I mean, by a software command. Even better if this command physically isolates me from internet. Assume I'm not running a GUI.

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.

Here is my problem:
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?

short version: My bluetooth headset keeps disconnecting.Full version:I'm using a 64-bit distro of 9.10 on a 1.6 GHz AMD Turion 64 laptop, with an external bluetooth dongle and a bluetooth headset. The dongle is recognized right off, the headset pairs perfectly through the bluetooth preferences panel, and sound redirects through the soundpreferences panel... For about 2 minutes. I know, it's odd, but every 2 minutes or so bluetooth disconnects from the headset. Sound shifts to the speakers, the applications don't miss a beat, and when I reconnect the headset through the bluetooth control it shifts right back to the headset. This happens regardless of other programs running. I tried it with no other applications running, and with a fairly heavy load, and it reoccurs.Here's the odd part: I had the CPU set on "Ondemand," to save battery power, but when I plugged in and shifted it to "Performance," it started happening ever 4 minutes or so...I've Googled around and found plenty about getting my headset to connect, but nothing about KEEPING it connected

Wifi seems to disconnect fairly requently, sometimes reconnecting automatically and sometimes requiring me to re-enter the wep password.
I would like to make it so it stays connected.
The router is not very close, but I think it's close enough. I even moved it closer. Other devices (such as my N900 mobile phone) hold the connection without issue.
One complication is that there are several devices all with the same SSID, though there should be one which is clearly stonger.
Details below.

We have a new EC2 instance which has Ubuntu OS. When I connect it through putty and start any process e.g.tomcat server, I can ping that server from my local machine and it works fine. But as soon as I disconnect through putty, that server goes down. Even, I tried to run it as a background process (using &) but did not work.

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
Code:
[ 15.668746] alloc irq_desc for 33 on node -1
[ 15.668748] alloc kstat_irqs on node -1
[ 15.668768] iwlagn 0000:02:00.0: irq 33 for MSI/MSI-X
[ 15.696615] alloc irq_desc for 22 on node -1

Did the protocol change? I have to restart Pidgin whenever this happens before I can rejoin the room.

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.
Things you need to know Operating System - Ubuntu 10.10 64-Bit Wireless Adapter - Hawking HWUN3 Hi-Gain Wireless-N Network USB Adapter Router - Apple Airport (99% sure it has all updates)

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.
Here is my ifconfig results:
Code:
eth0 Link encap:Ethernet HWaddr 00:0f:b0:87:b3:80
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I recently did a clean install on my ASPIRE 5490G laptop with 9.10x64 and am having some odd problems with wireless.
The wireless will suddenly drop and ask me for re-authentication of the encryption key which I put in. Then it will ask me again. It will then refuse to connect to the router.
If I hit cancel then on the notification area the nm-applet will not have the router listed in the wireless networks .
If I kill the nm-applet and restart it with ALT-F2 and run nm-applet --sm-disable it still does not show the networks available.
I know it is not the router as my flatmate who I share with uses a laptop with Windows 7 and they have no problems.

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:
auto lo
iface lo inet loopback
address 127.0.0.1

I was excited to use empathy in 10.04; however, both in the Beta and the Full Release I experience the following. (Note: I'm using 64 bit.)Setup 'Wizard' adds GTalk and Facebook Chat just fine.Manually add a IRC account (can't do that from wizard).Manually add a SIP account.Enjoy that it's working, and think that the full release fixed the bug.Disconnect
Then the next day.Set status as available.Get an ambiguous 'network-error' for GTalk and Facebook.Disable all accounts.Restart empathy, enable GTalk, get same error.Delete all accounts, restart system, go through account 'wizard', add GTalk, same error.Upgrade to dev version of Empathy, notice it's no longer in the nice messaging applet, but GTalk connects.Disconnect/Reconnect - same error.
Anyone else having this problem? Seems something is breaking with Jabber on Empathy. But I can't find any related information. I'll post logs when I boot into the 10.04 installation (which I was hoping to switch to, but not so sure right now.)

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 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.

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.

About every couple of days, my linuxfiles mount will disconnect. I notice this because I have created a symbolic link from my user's home folder to this drive. So when I log in, if the drive isn't mounted I get the following errors:
Quote:
Could not update ICEauthority file
/home/johnathan/.ICEauthority
Quote:There is a problem with the configuration server. (usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256)
I keep having to remove the mount folder and then readd it. Then I have to reapply the permissions for it to connect back to those files. How can I correct this? This only happens to this mount, the others stay connected with no issue. Also, when I log in and I have this issue... I cannot get out of this or log off unless I shutdown my laptop... is there another way? I guess I could do an init 3 from the CL.
