Ubuntu Networking :: Internet Connection Lost After 10 Minutes Surfing
Apr 23, 2011
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 fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.

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.

I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.

I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!

As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.

I am a non-techie, have been gratefully using Ubuntu 8.10 for a few years for the basics: email, web, documents, photos. I have somehow lost my internet connection, but strangely my email still works...!?!? My router is showing all the correct green lights, but I cannot get to any url. I am posting this thread via work (windows) pc. I have searched on this forum and in anticipation have done as much homework as possible, see below.I have a Netgear wired router. I cannot find Network manager on the menus and tried this from the terminal:
Code:
network-manager
bash: network-manager: command not found
networkmanager
[code]....

We have an Asterisk machine that we suspect periodically loses internet connectivity, causing all calls to drop. First, would this sort of thing be logged anywhere out of the box? I haven't noticed anything in /var/log, but that doesn't mean it's not there. If this is not typically logged, how I might go about logging it? I'm currently running a bash script from cron every 5 or 10 minutes which pings Google and writes success or failure messages to a log file. This works fine for extended outages, but if the internet connection drops and comes back between cron runs, it won't be caught.

I installed Fedora today, and I automatically had internet connection, I never had do configure anything myself. Then, I was playing around with VPN for a good while (trying to set up the VPN connection to my University), and now, I suddenly lost my connection to the internet!
But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!
Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...
I already restarted the Computer, but that didn't work, and Google didn't really held either.

I have been using ubuntu netbook 10.10 on my Dell Mini 9 for the past few month without any problem; it connects wirelessly to the internet via a wireless router. Yesterday in the middle of web surfing, suddently firefox cannot see any website outside of my home network (Firefox displays Server not found page). No help when I rebooted a few times and connect to my home network via wireless or even wire cable; it can access files in my network file server (DNS-321) but not the internet. My desktop computer running Windows Vista and ASUS media player has no problem accessing the internet.

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'm running 10.10 and I uninstalled some files through synaptic and it also removed a lot of other packages which messed up my whole system. I lost the connection to the Internet and also the taskbar. I don't know how to re-install those lost packages because I have no net connection. How can I fix this? This is what I removed:
Completely removed the following packages:
apt-xapian-index
libboost-python-dev
python-xapian

Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.

I have been having come problem, my surfing speed has gone to zero. I can download at full speed but surfing is crawl speed or just timing out. I am pretty sure it's because firefox is clogged, I just want to know is there a way to clear the clog w/o losing my settings? I fixed this before by making a new user, but I don't want to loose all my saved form's and bookmarks.

I played with the Network Settings section in YaST, because I wanted to use the wireless network card I installed into the PCI port. OpenSUSE recognised the type of card and its MAC number, and told me that I needed to install a firmware (fwcutter something). I tried some changes on the cable internet connection (like activate on plugged) while I tried to change the wireless connection (like activate on boot).
What I have now is that my cable internet connection is not working at all (it was working just 3 days ago), my wireless internet connection is, as always, not working either. I managed to work the wireless card on Windows XP by finding its drivers.
Since the problem is with my office computer, I cannot answer the exact brand names of the ethernet card and wireless card. Shall I reinstall OpenSUSE 11.3 from the DVD I have?
Second problem: OpenSUSE does not recognise my external harddisk, it gives an error about mounting the device.

I installed ubuntu 10 just yesterday. Everything was working just fine. The auto-update function advised me to download and install the latest updates and so I did. It was over 300 MB. I installed it, did a reboot and my internet connection was lost. I tried a few things I found on this forum yesterday. Nothing worked. I can go on-line on the same computer using windows 7. But I always have to reboot to try the different solutions. All right that's fixed! But now I just have to fix Firefox...

Is there anything I can do to the push rule of the servers's config file?

After having updated unconditionally all packages in Kde-desktop-factory-repository to get the latest version 4.4.4, I can no longer connect to the Internet through Knetworkmanager. I receive the the following message from a pop-up window when clicking on the Knetworkmanager icon

It was working fine up till about a week ago. A substituted computer will work OK from the same output from the Router/ Modem through the same cable.

Having 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. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

I 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:
CONFIG FILES:
/etc/ppp/option.l2tpd
-----------------------------
ms-dns 10.248.75.4
ms-wins 10.248.75.4
asyncmap 0
auth
crtscts
