Ubuntu Networking :: Connection Lost After Router Restart
Aug 11, 2010My ISP pushes software updates occasionally to my router. This also forces the router to restart. When the router restarts, my ubuntu box loses its network connection and does not automatically restore it after the router comes back online.How can I configure ubuntu to restore the connection once it is available again? It happens on my windows workstation...I am using ubuntu on a box with no screen / keyboard / mouse it serves as a fileserver and I remote desktop in. Obviously if the box drops the connection it is a major annoyance. I am using version 9.10

Nov 19, 2010I 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:

Ubuntu Networking :: Lost Internet Connection - Now Can't Get It Back
Jan 23, 2010I 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.

Jul 25, 2011I 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!
Ubuntu Networking :: Internet Access Allowed When VPN Connection Lost?
Mar 16, 2010As 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.

Ubuntu Networking :: Internet Connection Lost After 10 Minutes Surfing
Apr 23, 2011I 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.
Networking :: Detecting And Logging Lost Internet Connection?
Dec 8, 2010We 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.

Jun 16, 2011I 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.

My desktop computer running Windows Vista and ASUS media player has no problem accessing the internet.

Dec 2, 2010I am in college and live in a dorm room. As a dorm resident, I have access to only one wired network connection and I am not allowed to connect it to a router. My primary computer is multihomed and I was hoping I could share network access (eth1) through eth0 to a router. Then I want to hook up my secondary system to the router. I am not using the WAN port on the router. I believe this makes it act like a switch, which seems to be what I want.Here is my /etc/network/interfaces file on my primary computer

Networking :: Share An Internet Connection From A Computer With Two NICs ?
Feb 24, 2010Im posting after reading through a lot of articles explaining the same thing on how to share an internet connection from a computer with two NICs.
I have the following simple setup
When I first followed this guide
I was able to ping between the GW and a client on the LAN but couldn't access the internet from it. So I started to configure different things to get it to work which failed.
Now I can't ping between GW and the LAN. I tried to follow the same guide over again and even flushing the tables but still...
These are my current settings (without any chains).
(this client also has a wireless connection displayed in 'ifconfig')
Ubuntu Networking :: Computer Loses Internet Connection And Requires Many Reboots To Re-connect
Sep 5, 2010I am using Ubuntu Studio 10.04 LTS and I am experiencing the following problem: my computer loses its Internet connection and appears to require several reboots to re-establish an Internet connection.
As suggested on a similar post relating to wireless connection loss, I supply the output of sudo lshw -C network
*-network
description: Ethernet interface
product: NetLink BCM5789 Gigabit Ethernet PCI Express
vendor: Broadcom Corporation
[Code].....
Note that I have REMOVED my wireless card in case there was some kind of hardware conflict or failure. I am using a wired connection through a Linksys WRT54G router that is supplying an Internet connection to another computer and an IP phone without any problem.
When I run the command network-admin (or select System > Administration > Network) I can see only 3 tabs (General, DNS and Hosts) It seems that the Connections tab has disappeared (and I believe this happened when I upgraded from Ubuntu 9/Karmic Koala). If I click Help it shows me that there should be 4 tabs, not 3.
The connection dropping began prior to my decision to upgrade. In fact it took several attempts to complete the upgrade. Should I attempt to re-install the upgrade? I am not sure how to do it without losing my connection. When I visit System > Administration > Update Manager, I am informed that my system is up to date.

View 1 Replies View RelatedUbuntu :: Restart Internet Connection In System?
Oct 21, 2010I did a bit of searching, but I guess I'm not sure of the terminology associated with what I'm trying to do.
I'm currently connected via ethernet port (NOT wireless) to my DSL modem.
Every so often my connection gets 'saturated', typically after or during a lot of bittorrent activity that maxes out my bandwith, and my speeds drop markedly, even if the bandwith isn't currently being maxed out. I'm not sure whether it's my ISP throttling my connection or something else, but as a work around, I typically just disconnect my modem from the outlet and then replug to restore normal speeds.
Is there a way to 'restart' my modem from the command line in a similar way without having to physically turn off my modem to get the desired effect?

Ubuntu :: Still Have Wireless Connection But Lost Internet
Nov 30, 2009Three 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.

May 20, 2011I 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.
