I'm using Xubuntu and i have set up my DSL connection manually. I get disconnected from the Internet within 2-3 minutes. I have to again select eth0 from the network icon in the taskbar. it connects well but gets disconnected again and again. I don't face such problem when i use Win XP.
Any idea what might have gone wrong ?
I am new ubuntu user . I installed - ubuntu desktop v9.10 32bit. I have BSNL (Indian Telephone service) broadband connection. In Windows 7, BSNL broadband connection is working fine.
Now in ububtu I try to establish ADSL connection using following command: "sudo pppoeconf". It open a console based wizard and I'm able to create the connection. But this connection is sustain hardly 4~3 minute, after that it is disconnected. So, Again i have go through the same process again and again.
Our area was hit by a power surge and I cannot get the internet connection to work? What can I do. I'm using an AT&T modem which is connected to a netgear router.
View 4 Replies View RelatedThis is not the common problem that's on the stickied thread. I'm able to connect to my wireless network perfectly. I switch between Windows to game and Linux for desktop, coding, and hosting, so I can tell it has something to do with ubuntu 10.10. When I'm connected to my wireless network, at random times, my internet begins to slowdown, then I get disconnected from the internet, but the taskbar says I'm connected. This problem only happens in ubuntu and not Windows for some strange reason.
The applications that are usually open do not cause it, because it still does it even though I have little applications open (Google Chrome, gedit). When I'm on Teamspeak 3, I notice my ping rises to the 1000s randomly, and I get disconnected. Once again that only happens on Ubuntu.
I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!
I used this command to restart the networking but in vain
Code:
sudo /etc/init.d/networking restart
On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.
I have an LG R-450 laptop with Ubuntu 10.04 installed in it. When I connect him to a network (either LAN or Wireless) it stays connected for a few minutes and then Just disconnects (without showing any sign of disconnection except no internet/skype/dropbox). Only way to renew connection is after startup. The network controller is SIS 191 Gigabit Ethernet adapter.

First of all, it says the signal is 2 bars, when in fact my router is right next to me as of right now. Second of all, when I try to connect to it, it asks for my password 3 times, then says disconnected. I'm on a hardwire right now, it's across my keyboard, and I'm in a tangled mess.
View 2 Replies View RelatedMy Ubuntu web server is left on all the time, sometimes I notice that it is disconnected from the network so I have to goto the server and re-enter the password in the network connections, this allows me back onto the network. Why is the server being disconnected? (The computer is running all the time because if it re-starts the terminal window is open on the screen). And how can I stop it from happening? It's got to the point where I need to check it every hour which really defeats the purpose of having it!

View 3 Replies View RelatedHow to enable wifi? I downloaded and installed Debian 6.00 and as I couldn't get online with my Tenda USB Wireless Adapter. I downloaded Debian 6.00 again, this time the CD Net Install version with Firmware included. However, the added firmware version of Debian does not find my wireless either. My wireless adopter is shown as Bus 001 Device 003: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. There is a Network Icon in the Panel which when clicked shows "Create New Wireless Network". I have put in my ISP related network and my password and rebooted, but all I get is the message on my desktop:
"The Network Connection has been disconnected."
That isn't very polite, is it? Who has disconnected it and why remains a mystery to everyone except the culprit(s). I think I must have missed a basic step in the Wifi Enabling process. I checked the Use Permissions and everything is fine there, as User I have permissions to use modems and do networking and so forth. Also I should like to try "modprobe" but I see the package isn't in Synaptic Package Manager.
I have an Asus laptop with a BCM4318 wifi chipset. result of lspsci command about wifi cards:
Code:
00:09.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) For some reason, I often get disconnected. Once it's disconnected, I cannot connect anymore and I need to reboot my laptop in order to get the connection back! I didn't have this problem when I was on Ubuntu 8.04. I checked in /var/log/syslog and I found this when the network is disconnected:
[Code].....
My promlem is that I wrote a few simple script to monitor the network connection as follows:
script 1 "netmonitor.sh"
#!/bin/bash
# /usr/local/bin/netmonitor.sh
HOST=www.google.hu
ping -c 1 "$HOST" > /dev/null 2>&1 .....
So it's run every 5 minutes, and it works well, when it sees host is down, it restart the connection, BUT as the log shows below, about a half an hour after using the connection (for example the ssh through the internet or the vpn clients disconnected) , br0 (probably) goes down or something and the script needs always restarting the connection...
The log:
Fri Jan 21 14:45:01 CET 2011 Network is ready! .....
Fri Jan 21 15:55:41 CET 2011 Network seems down, rechecking...
Fri Jan 21 15:56:21 CET 2011 Network is down, restarting interface br0!
Fri Jan 21 15:56:48 CET 2011 Network is ready after interface br0 restart! .....
Then if I use again, its ready... Is it possible, that if system don't use the connection after getting the DHCP lease, it close the connection automaticly? Anyway it works ok, but I don't want to owerwrite my router's flash in every 5 seconds with te new lease, my script probably defeat it soon if I don't do anything.
I recently installed Ubuntu. I just installed ndiswrapper so I could install my wireless PCI [COLOR=blue ! important][COLOR=blue ! important]card [COLOR=blue ! important]drivers[/COLOR][/COLOR][/COLOR]
I did that and it is recognized and so is the network I want to connect to. But for some reason, it just wont connect. It will spend a long time trying to connect, but then just says "disconnected". It's not like I have a bad connection or anything. My internet on Windows is fast.
OS: Maverick Ethernet driver: tested with sky2 an sk98lin This has been driving me crazy for the last few months: if I unplug ethernet cable while my laptop is on reconnecting it sometimes does not bring the connection back.
And once ethernet is gone nothing that I try seems to consistently bring it back. Rebooting, disabling/enabling the driver, disabling/enabling NIC in BIOS, changing driver from sky2 to sk98lin, deleting connection from Network Manager, resetting the router - nothing helps. It seems to come back randomly a few weeks later. Once I used live Ubuntu on a USB stick and ethernet came back not only on a live distro but then when I rebooted also on my main OS. But when I tried that trick next time ethernet was missing in the live distro as well.
Also once I was able to revive ethernet but compiling sk98lin driver, blacklisting sky2 and rebooting. Of course next time doing the same routine did not help. The thing is - ethernet works fine with either sky2 or sk98lin and I can unplug the cable and plug it back in most of the time without any issues. But then every so often - bang and I'm stuck with only wireless until ethernet suddenly starts working again.
I have installed Fedora 13 and updated it. I simply cant use ssh to connect to this Fedora, not even locally. I have enabled port22 in firewall settings and nothing. Tried to disable firewall completely and nothing. I have disabled SELinux (not sure if it has something to do with this, but... ) and nothing. Entered "ALL: ALL" in /etc/hosts.allow and still nothing. Dont know what to do anymore.
Here is what happens when I try to ssh to this machine, even from it:
[flibio@surf ~]$ ssh localhost
warning: Need basic cursor movement capability, using vt100
flibio's password:
Authentication successful.
Disconnected; connection lost (Connection closed.).
Connection to localhost closed.
[flibio@surf ~]$
Looking into Services > sshd and it says "This service is dead."
So I tried:
[root@surf etc]# service sshd restart
Stopping sshd: [FAILED]
Starting sshd: : OpenSSH_5.4p1 on
: FATAL: Creating listener failed: port 22 probably already in use! .....
And still I get disconnected whenever I try to ssh to this machine from anywhere. Services says that sshd is allways dead, even restarting it but I can only restart it by doing a pkill sshd before.

I logged in through a new connection when connectivity was restored and looked at running processes. It looked like yum was hung so I killed it (big mistake and one I won't repeat).
Now, when I try and run yum, I get the following:

View 4 Replies View RelatedIf i leave my laptop idle for sometime, my usb datacard connection gets disconnected. I know its a dial-up connection and if no application is accessing internet it disconnects on its own. The problem over here is when i click on the icon and click on activate it won't happen. So, i have to unplug the hardware and then re-insert it to make it work again.I went through a site, there they have mentioned a work around that is to keep a ping command always running. I'm fine with that, but why do we need to remove the hardware n re-insert it to make it connect to the internet again

View 4 Replies View RelatedHaving struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out.

View 1 Replies View RelatedI'm running Ubuntu 10.10. I have a problem with any client side network communication from any java based program/application. I've tried to run the following code:
Code:
public static void main(String[] args) throws Exception {
long start = System.currentTimeMillis();
Socket s = new Socket("ubuntuforums.org", 80);
System.out.println("1. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); start = System.currentTimeMillis();
s = new Socket("ubuntuforums.org", 80);
System.out.println("2. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); }
The result is the following:
Code:
1. connection created in 189.31 s
2. connection created in 0.085 s
I've tried both java-1.6.0-openjdk and java-6-sun-1.6.0.24 with almost the same results. During the extremely long 189 seconds, the processor is doing almost nothing (java thread has 0 %). I've tried also a wireshark to check what is going on, but the first packet was released after those 189 seconds. There is nothing in log files, I have no exceptions or errors, and the connections work (after the first long delay) just fine.
I just installed the Natty Beta and plugged in a Netgear WG111v3 USB wifi adapter. It is using the RTL8187B driver and worked out of the box. The problem it loses my connection every few minutes. Sometimes not for 10 or 15, sometimes like a minute or less. After it loses the connection, I have to uncheck "enable wireless" (which I assume is the equivalent of bringing down my wireless interface) and then check it again before it will let me reconnect. I don't want to try ndiswrapper because the card works great when it works, including monitor mode and packet injection!
View 3 Replies View RelatedI installed Fedora 14 yesterday via the installation DVD with 3,3 GB. Everything worked fine and when I connected to my wlan and entered the WEP key I got access to the internet. But after about 5 minutes, to connection just got cut and I was again asked for the WEP passkey. But when I entered it this time, the connection failed and I was just asked again (with the same key entered, it even got it saved from last time). As you can think, this is quite annoying, since the time I have internet is not even enough to get some updates done.
Ah, and by the way: The time I have internet it just is unbelievably slow. On my Windows partation, I don't have this problem. I do have a small hint what might be the problem: When I was using Ubuntu, I always had a similar problem, but it did not even connect to my wlan once. The solution was to blacklist some driver, but since I don't know if this might be the problem on Fedora too and if the drivers are the same as on Ubuntu and since I really have no idea about the syntax of the terminal here, I was not daring to try this out.
Hello, I've installed OpenSwan with xl2tpd on my server, and set it up for roadwarriors connecting using certificates.
My server is Debian 5.0.8, I am running xl2tpd 1.2.0, and Openswan IPsec 2.4.12, my clients are all Windows, and I am testing my setup on a Windows 7 client.
I have no problem connecting to the server, but after some time the connection drops. I removed the idle option from the ppp config but it does not make any difference.
Even when I create constant traffic with ping -t the connection drops also.
I have no problems reconnecting right away.
I have been hacking at this for a couple of days, reading every post I can find, but I have not found a solution to my problem.
Here are my configs and logs:
