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.
View 3 Repliesa 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.
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.
I've seen many threads of this type, but I didn't see anyone simply say what the problem is. There's got to be something happenning to make it disconnect, and then something else makes it so it can't re-connect.What I get is that it connects for some time (maybe a short time, maybe a longer time) but eventually it just disconnects. When I try to re-connect wpa_supplicat log says simply it's trying to associate with the AP; it's associated with the AP; and then it's disconnected: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
It is a home-built with AMD64 and a D-Link DWA-160 A2 (Atheros AR9710) and Netgear extreme 300 router AP. The router log shows it is in fact connecting for a short while only to be disconnected at my computer's request.This is Fedora 13 out of the box (sort of!) except that I have the development repos and the updates repos and the RPM fusion repos installed. I have NM applet running. I use one called simply "network", and also one called "control network devices". but they all lead to the same result that it can't reconnect. If I play with it enough doing any variety of changes I can eventually get it to reconnect, but there's no telling what action was the successful one. I just think it reset whatever was bothering it. But, as I saw another thread describe, if I delete ALL network connection definitions and reboot, it will find the network and it will connect. But sooner or later I'll be back to where it disconnects.So, does anyone actually know what the major malfunction is? It should have been identified and qualified and quantified by now so that there's a simple write-up of cause and fix. But thru all my googling I can't find anything definite. If anyone has some good answer please post it so we all can benefit.
I LOVE Ubuntu,but the sketchiness with WIFI in Ubuntu is really frustrating (not that it's Ubuntu or GNU/Linux's fault necessarily). I'm trying to find a good WIFI card replacement for my girlfriend's MSI Wind u90, but seems both the Intel 3945abg and the Intel 4965agn - the cards usually recommended for that model - seem to be spotty at best in all recent versions of Ubuntu including the last long-term release. Has anyone had success with a Broadcom 1020 (in any laptop but especially in a netbook)?
View 1 Replies View Relatedsince the upgrade i see all avaible wifi networks as they have 100% signal, both in NetworkManager and Wicd.in iwconfig and iwlist the signal levels change, but the link quality remains the same: 70/70 (see below). What could be worng? What can i do?

I just installed 10.10 on a my new Aspire One Acer netbook and I got a mobile broadband USB stick from Wind mobile.
The stick is activated because it works on my 20 GB Windoze 7 O.S. but it doesn't work at all on my 140 GB Ubuntu O.S. Both systems are on the same machine so I know it's not a hardware problem either.
Here's what happens: I log on to Ubuntu, plug in the stick and I select the "New mobile broadband GSM connection" in the network connections menu.
From there I selected my country (Canada) and my mobile provider (Wind Mobile) than I selected my plan (Mobile Broadband) and my APN (broadband.windmobile.ca).
Then the stick blinks slowly and the network icon looks forever for a connection but no matter how long I wait no connection ever establishes. My roomate has it working on his HP laptop Ubuntu but no luck on mine. The stick just keeps blinking, a steady light indicates a connection.
I'm running Arch Linux on an Acer laptop and my wirless connection doesn't stay up. After a while it disconnects, and when I try to reconnect I get stuck with a "Waiting for authorization" message. I have to retry several times before getting the connection stay up for few minutes. This happens with both networkmanager and wicd. The strange thing is that the iMac that sits next to the laptop connects fine, and when I use my laptop within the university wireless network it works normally.
EDIT: I've tried to connect manually following the steps
iwlist wlan0 scan
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
dhcpcd wlan0

I am a newbie when it comes to linux, but know a little (the little bit of dangerous stuff).I have set up a home web server for when I am testing website using PHP, mysql and other funky stuff. This is a reflection of my production server as far as I can with my limited knowledge.I am also using this box to learn more about the Linux operating system and I doing this slowly. Before I installed the GUI (Gnome) I was using a text based server, this was working fine and running absolutey fine and never disconnecting. This has been fine and working 24/7 for around a month.
At the weekend (just gone) I ran the following at terminal
# apt-get install gnome
This gave me a GUI so I could try some other things.
When the computer is idle the network card seems to drop the connection, Im trying to see after how long it does this. I have seen this work fine after an hour, but after a night, the network has been dropped. This is a hard wired connection to the router.first time I thought the PC had froze so rebooted the PC, but the second time, I plugged a mouse into it and noticed the the network icon had changed, after right clicking on it, i noticed that It had dropped the connection. After clicking the "reconnect" option it is back up and running.
I am running a 3-G wireless USB broadband modem, and connecting with Network Manager, but I keep getting disconnected when idle after 5-6 minutes. I am used to using Kinternet to connect with my 3-G wireless USB broadband modem, and setting it up in Yast / Network / Modems, but was not able to configure my modem there (for some mysterious reason) so ended up using Network Manager instead.
What's going on here regarding YAST being unable to configure my modem (even when Network Manger is disabled). But my main problem at this point is that my connection times out after about 6 minutes if I'm idle. This is a big problem for me because I type slow and frequently get disconnected while posting on message boards. Where are the idle time out settings are for Network Manager? I can't seem to find them.
I want to know any command which is equal to disconnecting and reconnecting lan cable. actually sometimes my router takes some time to connect to internet and when this happens my desktop shows network disconnected. but when router is connected system does no detect it and i have to manually disconnect and reconnect the cable which is not convenient.
I have debian 6.0.1 (squeeze) with gnome 2.30.2
And i have already tried following commands:
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.

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

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.

View 1 Replies View RelatedI've searched on-line and through these forums and I am still not able to find a solution to my problem. To start off, I do not know if my wireless card is turned on or off. I press Fn+f8 key and the LED turns on but Ubuntu does not detect the wireless networks. I am able to connect using the Ethernet port.

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 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:

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

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.
View 2 Replies View RelatedMy 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'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.
View 2 Replies View RelatedHere 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?
