Ubuntu Networking :: Internet Not Connecting Unless Restart Computer Several Times?
Nov 19, 2010
I am having a problem with my internet connection. It only works half the time. Usually when i start the computer it doesn't connect until i restart anywhere from 1 - 10 times. I did sudo ifconfig while it was not working here is the output:
eth0 Link encap:Ethernet HWaddr 00:19:d1:00:36:41
inet6 addr: fe80::219:d1ff:fe00:3641/64 Scope:Link

I recently set up a network of computers via Ethernet, all of which use Fedora 10. I would like to be able to get any computer on the network to hook up to the internet.(I think the solution is now figured out - see below, on page 2, "problem solved")

I have just installed ubuntu 7.10 on my computer. The problem is getting it connected to the internet using my Sony Ericsson w580i as a modem. I have used my phone to connect to the internet on XP operating system easily. Please assist me and try to give me a more simplified step by step procedure.

I installed Gnome Nanny. I can choose the times when the computer can be used and limit the internet. However, these times are not being enforced. Is there some other settings that are used to enforce these settings?

I had been manually starting my wireless network with "sudo iwconfig wlan0 essid "my wireless router id". The network would start and work flawlessly for weeks at a time. I can't ask my wife to find the essid in the terminal and then start wireless manually when I'm not here. She hates and fears the terminal. So I downloaded gnome network manager for a point and click interface on gnome panel.The network would start fine but shut down after anywhere from one to six hours. It would then refuse to restart manually or otherwise. I completely uninstalled network manager and tried wicd instead. The same basic problem is happening. The network will restart if I reboot the computer. My system:
Desktop computer acting as proxy server for the internet. Internet connection is by a dial up modem. This computer uses a wireless pci card connected to a dedicated hub. This is for file sharing via nfs. The OS is ubuntu 9.10. My wife's computer sharing the internet using a proxy to my computer. File sharing via nfs and a wireless card. Also running ubuntu 9.10. This same basic system worked flawlessly under Ubuntu Hardy.My desktop was updated recently with new hardware which created the need to move to Ubuntu Karmic. Some hardware was too new for hardy to deal with.

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

This problem started a few days ago. Whenever I attempt to connect to a wireless connection via network manager, my computer completely crashes, going to a black screen with no input from keyboard or mouse. It forces me to reboot using the power switch. Everything works fine when I connect to an ethernet cable, so I am sure it's a problem with my wireless driver.
I already tried (successfully) reinstalling the ath9k driver via compat wireless as was the advice from other forums, but this had no effect. I'm currently running opensuse 11.4, and haven't had this problem until a few days ago
This problem seems a bit ridiculous for a task as simple as connecting to a wireless network, so I'm convinced that either there is some sort of relatively simple way of fixing it, or windows really is the only decent operating system out there..

My desktop computer, running 11.04 (fresh install) sometimes can't establish a wired Ethernet connection. Sometimes when I boot, it keeps trying to establish, but with no luck. I keep trying to choose "Auto eth0" from the networking menu, but still, it doesn't succeed. If I reboot, it sometimes works. I can't establish a connection about half the times that I boot.
The computer is connected with a cable to a router ("Belkin Wireless Pre-N router"), and the router is connected with a cable to a cable modem.I've been using Ubuntu for a while, and I've had a problem for the past few versions (since around 10.04)? I thought that it might be some old issue that got resolved, so I did a fresh install of 11.04 today, and still have the same behaviorI'm willing to try things next time I can't get a connection, but don't know what.

I have 2 computers in my house, on my network. I want to connect to one computer to the other using SSH. On one I installed "OpenSSH-server". "OpenSSH-client" was already installed. I go to the other computer to try to connect to the "server" computer and I enter in the terminal:
Code:
ssh username@192.168.0.33
It never connects. The text input "bar" keeps blinking, it never connects and I get the "Connection timed out" message.
how I can connect to the "server" computer? What am I doing wrong? And if I edit my "/etc/ssh/sshd_config" file to listen to port "12345" how do I get the other machine to connect to that port?

I have Ubuntu server installed on my old machine, which has no avahi running. I want to be able to connect to it by hostname. Is it possible. I have a tp-link TL-WR941ND router, but it doesn't seem to have any related options. How can I do it? Is there another way?I know I can add them on by one to the host file, but that is not what I want. Also that wouldn't work well with DHCP, and new hosts.

I hope someone can help me. Been using Ubuntu for over a month now (My first foray into Linux) and I love it...BUT I'm having an intermittent problem that seems to be getting worse:Ubuntu will be working fine....then I'll go to open a program (like Chromium or Thunderbird) and it won't open. If I already have Chromium open, it might become unresponsive. If I'm downloading something, it will start acting weird (Like last night- I was downloading c.600MB file and Ubuntu went into dysfunctional mode- and said it was downloading a 2006453 GB file!)
Also, when it goes into dysfunctional mode, any dialogue boxes that come up (like the shut-down confirmation box) will be blank- just pure white- with no text or buttons visible.I can't even run any terminal commands when this happens, to try and diagnose the problem, because either terminal won't open, or if it does, it will be blank like the dialogue boxes- i.e. the purple background will just be replaced by pure white, with no cursor or text).I'll then restart the computer when these things happen, and then I'll get the "The disk for /tmp is not ready yet or not present" and have to press "f: to fix it- then it will boot up and work fine- sometimes for the rest of the day...sometimes for 5 minutes.
Since I don't see anyone else complaining about such behavior, I assume the problem is with my 'puter or my installation? If anyone has any ideas, please help. I really don't want to have to switch to a different distro- as I love Ubuntu///and I don't want to have to reinstall - as I have it configured the way I want it and plus it's on a partition (Still need to keep Win-D'ohs around just for when I want to use Magicjack)This is starting to happen several times a day...HELP...can't. Go. On like this![My 'puter's specs: Compaq Presario SR2170NX P4 3.0Ghz 1G Ram 150GB HD -all I usually do these days is email and the web]

I have Ubuntu 11.04 on a disk, and installed it on an empty hard drive. When I start my desktop my screen is black with a flashing "_" in the top left corner... Nothing happens. I usually have to restart the computer multiple times before it will actually work. I tried running Ubuntu in recovery mode and fixing any broken packages, but no luck.

I am trying to connect to an apple computer wirelessly to get access to the internet.. If no encryption is used on the network (gateway?) set up by the apple computer I can connect just fine and browse the internet.
-If a WEP encryption is introduced I cannot seem to connect... even though the WEP keys are identical.
-I have tried both WEP 128 passphrase and WEP 40/128 key... -Have tried the WEP passphrase being both just numbers in case that mattered.

First off, i have ran 10.10 for the past 6 months without any problems. Then last week i decided to try 11.04. I installed using Wubi. Now the problem is the computer only freezes when I am using a web browser (firefox). it completely freezes where I can do nothing, so I will kill it with the power button. When i try to restart, not even the bios will boot up, just a blank screen with the num/caps lock key flashing.
But after trying to restart several times the bios and boot loader will eventually come up and will start up normally until the same thing happens. I decided to reinstall using wubi so when i tried to boot itno windows, the windows partition was corrupted. I fully restored windows and installed 11.04 with wubi again only to have the same freezing problems.
I will be trying 10.10 again and see if it just a 11.04 issue, but thought this problem should be out there if anyone else has a similar experience

I'm currently running Fedora 13, after I updated the kernel to 2.6.34, I have to run (as a superuser) "service NetworkManager start" in order to start my network manager, is there are way I can run this on startup?
Also my ethernet connection seems to only work when I restart/boot up my computer, when I wake my computer up from being asleep, the ethernet stops working.

When ever i run ssh -p <port> <user>@<remote IP>, i get a connection has timed out error. (i use the -p <port> part because i'm using a custom port). does anyone know what could be causing this? i know of a few *possible* problems, but i don't know how to test them all.
- I am on the same network as the server (I'm trying to test using remote IP to make sure it works before i go out an try it somewhere else)
-The router could be blocking it (i'm using linksys)
-IPtables may not be set up right (i think it is though. the only thing i've run is "sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT". I have changed the port for the server since then. maybe i have to restart it or something for it to recognise the change? I know very little about IPtables though).
-maybe i have to change something in my client or server config files? (the only config file i've changed is the sshd_config file on the seerver, and that was to change the port to my custom port).
thats all i can think of for now. It may be none of those. I do have the sshd_config and port forwarding in my router set to the same port, so thats good.

I would like to connect a PC (it has no white IP) through Internet. It's possible to create tunnel with SSH, but I need more easy way. May be there is some service exists (like TeamViewer), so people can just run simple command on that PC?

I have a problem which is connecting automatically to my spwireless. On my windows, my schools provide me the disc which contains several .cer files and a automated batch files to copy the .cer files to the root folders. I can choose to use the other network but in using that, i have to manually connect compared to using the spwireless. Anyway, my problem is that, how do i add the .cer files and to where so when i connect to the network it will look there for the cert. Because when i manually connect, only one cer can be chosen.

I am having occasional internet connection problems on startup. 1 out of 5 times that I start my computer, I will have absolutely no internet connectivity, can't ping my router, obtain ip. nothing. Tried re-establishing connection with no luck. Status light on my router displays a slow flash. I restart, problem solved. Not so much a major problem, but irritating at times
