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

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

Ubuntu Networking :: Wifi Keeps Disconnecting ?

Mar 9, 2010

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.

Ubuntu Networking :: ZTE MF637 Keeps Disconnecting After A While?

Aug 13, 2010

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.

Ubuntu Networking :: Wireless Keeps Disconnecting On 10.10?

Nov 8, 2010

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)

Ubuntu Networking :: Wireless Disconnecting In 9.10x64

Feb 13, 2010

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.

Ubuntu Networking :: Wireless Not Working In 10.04 - Disconnecting Again And Again

Jun 1, 2010

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

Ubuntu Networking :: Internet - Router Disconnecting ?

Feb 14, 2011

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.

Ubuntu Networking :: Can't Reconnect To Internet After Disconnecting

Aug 16, 2011

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?

Ubuntu Networking :: Wireless Disconnecting Every Few Minutes?

Jan 16, 2010

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

Ubuntu Networking :: How To Resume SSH Session After Disconnecting

Mar 7, 2010

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?

Ubuntu Networking :: Realtek 8185 Disconnecting After A Few Hours?

Oct 2, 2010

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.

Ubuntu Networking :: Apache2 And Localhost - Network Manager Kept On Messing Around And Disconnecting

Mar 14, 2010

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.

Ubuntu Networking :: Constant Wireless Disconnecting With Intel Based Card

May 2, 2010

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.

Ubuntu Networking :: Mobile Broadband Keeps Disconnecting, Network Manager Remains Silent?

Apr 18, 2010

I have a broadband mobile modem iCon 225 (Option) with SiMobil provider (Slovenia). I run ubuntu 9.10 (Karmic Koala). I connect to the internet without problem. After a few minutes, the modem lights start signaling that there is no connection, but the network manager shows connected status. I have to reconnect the network manager to regain connection. After about a dozen times of reconnecting like this, I have to reboot the system, as it won't connect, even if I unplug and replug the modem.

I've noticed these frequent disconnects have started a few days ago. I did experience disconnects in the past, but as nearly often as this. I can't attribute disconnects to activity/inactivity, as they seem to happen no matter what I do.
