Ubuntu Networking :: Internet Connection: 'Work Offline' - "No Network Connection"
Oct 31, 2010
I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?
I had work well with opensuse 11 and the internet also work well but when I turn off my computer and then use the XP and work with it. I find out the connection with the internet doesn't work in the opensuse 11. I made a repair and format to opensuse 11 but without any change the net still doesn't work.
CPU Pentium4 Motherboard Gigabyte intel 945 S-series Dial up connection I have no experience with opensuse.
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
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 have just recently installed Ubuntu 10.04 and I can't get the internet connection to work. I have found out that the wireless adapter that is pre-installed in my laptop (toshiba satellite A665) has been interfering with the main wireless.
The adapter Ubuntu is trying to use it my WiMAX local wireless adapter which is incorrect. My main wireless adapter is my Intel(R) Centrino(R) Advanced-N 6250 AGN which Ubuntu can't find.
Every time I turn on my ubuntu box, it somehow kills our internet connection... yes, even through the router. The internet will not work until I call tech support and they run a line test. Then it works again as if by magic. I'm at a loss. A friend suggested maybe ubuntu is trying to establish itself as the dhcp server on the network? I have ubuntu 9.04, 32-bit, workstation.
i have a routed and a PPPoE type internet connection, recently i tried a thing in terminal with the pppoeconf option since the network manager has problems with connectiong to the internet with a pppoe DLS connection, or anyway in my case it does not work. Ok i did the pppoeconf thing i inserted my pass and my user and left the program to do its thing, ok it all worked fine but then i restarted my system and suddenly the network manager did not want to recognize my network it hat as options some weird ipupdown options for connection and when i tried the pppoeconf thing again it did not work. what could i do to reactivate at least one way my connection, if i understood correctly the terminal type connecting and the network manager are two different things. now i am using my router and it should connect but the network manager still does not see the connection.
I installed Ubuntu 9.10 using the default setup (Gnome I think) and on my Gateway Notebook using a wireless connection. It appears to be working great and I can even see my Windows drives and network storage on my home office systems.I have also set it up to run my favorite Bible software on Windows running under VirtualBox. I then installed the KDE Desktop so that I can select either desktop when logging on.
However, once I am in the KDE desktop, I cannot connect to the internet. I have checked and double-checked and the wireless settings seem to be the same on both the Gnom and KDE Desktops but still no network or internet connection when using KDE. I might mention that I am using the 64 Bit version of Ubuntu.
I'm trying to setup network server for a week now and I was able to setup network in which i can ping the other workstation that is connected to my switch which is also connected to my server and I can also ping the server from local workstation.
I have 2 NIC, I use eth0 to dial to my dsl connection(ppp0 has the IP of my internet) and I use eth1 to connect to the switch and use to connect to the other local workstation
Now my problem is I don't know how can I share the internet connection from my eth0 or the ppp0 to my eth1 to the network, what do I need to be able to share the internet connection to the workstation that is connected to my switch.
I cant get my wired internet connection to work. The command 'dpkg -s pppoeconf' returns ' installed ok installed'. My connection is through a router which is probably in a semi-bridge mode and I need to dial a connection to get the net started. The connection Auto eth0 is setup properly with the correct cloned MAC Address (that of my laptop).
I've also executed 'sudo pppoeconf' and ran the whole series of steps which towards the end said that my connection will be set on boot. However, the net doesnt work directly and I dont know how to dial manually either. 'sudo ifup eth0' returns 'interface eth0 already configured'. I tried some 10-15 threads but none worked. Ubuntu is handicapped without internet.
I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?
I just installed Ubuntu Netbook 10.10 on my Lenovo ideapad S10e. Under the network manager it says that firmware is not installed for the wirless card but that is something for a different day. On the ethernet connection it attempts to connect via dhcp and then comes up saying it is disconnected. I attempted to set it as a static connection, when i do that it shows that its connected but I still can not connect to the internet.
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
As of now, my internet works fine when connected with an ethernet cable.The problem is it doesnt seem like my wireless is working at all.The led light is orange, (its usually blue when it connects) and I cannot see my home dsl network.Is thereany specific troubleshooting steps I should take?HP dv6000 laptopwireless card: Broadcom Corporation BCM4311 802.11b/g WLAN
I have two PCs one has Windows XP the other has Ubuntu 9.10 on it, the Windows PC has no problems getting on the Internet (I'm posting this with it) and getting an IP address from the wired router. The wired router I have is ONLY wired it does not have wireless at all, it is currently setup to hand out IP addresses between 192.168.1.2 and 192.168.1.254.
The Ubunutu 9.10 PC worked great last night surfed all over the place for hours, then finally shut it down last night when I went to bed, shut down appeared to be normal like it always does when it shuts down, then this morning when I booted it up it gave error: "WIRED NETWORK - disconnected you are now offline".
I've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?
I've read a lot on the internet about various ways of doing this but i've been unsuccessful each time. Basically what i've done is accidently un-installed network-manager because I was having trouble staying connected on my WPA network. The easiest way of reinstalling it I know of is using the CD but I don't have a CD ROM drive and the pen drive I used to install it I no longer have.
I tried using a program called Keryx but you need python installed and from some reason this doesn't come with ubuntu 10.10. I've also downloaded the .deb packages but I still need to download 200kb which is a killer. I've also downloaded it from here too [URL] but the install file makes no sense to me as i'm not a massive linux user. One last thing reinstalling isn't really an option as i've already put a lot of time into setting up this computer.
Okay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
I have installed centos 5.5 / 64. Configured network but - no internet. On my router I see my pc and IP. On centos, Firewall and selinux are disabled. I try to disable network and activate network manager and reverse but no luck internet is not working. Try to ping my router 192.168.5.1
Sometimes either due to a power outage or due to lightning I turn off my Wimax modem and continue to use my laptop on the battery.Then when I turn the modem back on, there is no internet connection.Here's what I've tried:
1. turn off and on the network connections - right-clicking on the icon on the bar on top of my screen.
2. turn off and on the dsl-provider connection - no effect.
3. When I tried to re-do pppoeconf, it says that there's no response from the concentrator.
This has happened a few times in the past and the only thing I can do to go online again is restart the computer. And it works.Now on Windows, the double-computer icon showing a network indicates connectivity AND data movement. Unfortunately we don't have this on Ubuntu.I'm just after a restart and I'm online now. But I'd like to know if there's a way around this without having to restart.
I'm running Ubuntu 9.10 with fluxbox installed. Occasionally my internet connection will stop working, but when I check on wifi radar, I'm still connected to the network. The router is not plugged into a computer at the moment, just the cable jack. It is likely a hardware problem however, since my other laptops also experience disconnects. Any help beyond "change the cable" would be greatly appreciated. For instance, even though I am connected to the network, I cannot post at the moment due to lack of internet connection.
I have a Ubuntu 10.04 laptop that gets its Internet connection via WIFI using WICD as network manager, and Windows XP desktop with no Internet connection. What I want to do is share my Internet connection from my laptop with my desktop via a Ethernet cable. But i have no idea what to do. How do i go about doing this?
I have installed the driver of my Broadcom Wireless card BCM4312 ( Acer extenza 5620 laptop) and when i try to connect to my wireless connection it just try to connect for a while and then go offline i tested another usb wireless card and still no success
How do I tell the shared connection that it has a static IP and that I dont want a DHCP on the network?Do I have to set up DHCP on the box with the shared connection, even if that box only runs DHCP for a single IP address being the eth0 that is shared?Or can I tell the shared connection that it has a static IP and still allow network manager to run the shared connection?Or should I specify static IP's for all clients and the shared network manager and install say firestarter on the gateway to run the NAT for the eth0 out to eth1.
