http://ubuntuforums.org – I'm troubleshooting a network problem for an acquaintance. He's running Lucid Netbook Edition on a Thinkpad X41. A few days ago, according to him, he suddenly couldn't get online. He was at someone else's house and using their connection with no problems, then got back to his home network and couldn't connect. He can connect to his network, and if the Ethernet cable is plugged in he can get online. Two other computers running the same OS are having no problems with the wifi- I'm using it right now, actually. My computer and the Thinkpad both had the OS installed from (HowTos)

Stories similar to [ubuntu] No internet on wireless connection, but access through Ethernet

I haven't had a problem with this yet, but today I was online via my wifi connection and then the network center said there was no connection. My modem said I had full bars, and I tried restarting both the modem and the laptop, but nothing. The internet works if I plug in the ethernet cable, but will not pick up the wifi signal.

I have an Asrock A330GC, with onboard ethernet, and an Engenius PCI card for wifi.

I installed ubuntu server 9.10 no problems, and it picked up my ethernet in the installation with no difficulties.

I couldn't get 9.10 to do what i wanted, so I tried installing 8.4 instead. This however didn't pick up any of the drivers, so i couldn't get online.

[ubuntu] eth0 problems 2 years 19 weeks ago

Hello,

I just installed Ubuntu 10.10 on this box and plugged an ethernet cable in but even though Ubuntu claims it is connected to the network I cannot access the internet.

ifconfig says an ip (192.168.2.9) is allocated to the computer but according to my router it is not (0.0.0.0 and idle connection). The LAN ethernet device on the box is a Realtek RTL8139.

I have a computer that is connected to the internet via wifi. I then have a ethernet cable coming out from my wifi computer into another computer which has no wifi or place to plug into ethernet.

I have shared the wifi connection to the LAN port, and the computer successfully gets internet. But, on that computer I have a FTP server that I want the wifi network to be able to connect to.

Hey guys and gals!

I am having the weirdest problem... I have a work laptop (running Fedora 16) that has connected to my works wifi and ethernet without any problems. I have also connected to the wifi at my girlfriends place without problems. Right now I am at my place and at a total loss for words. I have connected to my home network via wifi and Ethernet... (obviously not both at once).

I'm using a WiFi connection on Ubuntu 12 and connecting to XP directly via Ethernet cable. I've set the ipv4 settings of the Ubuntu wired connection to:

share with other computers

and restarted. If the network cable is plugged in WiFi disables. Is this problem on the XP side? IP is set to automatically obtain etc. I'm only looking to share the internet access. Thanks.

Hi, coming here last time fixed the wifi, so hoping some one here can also help me get my ethernet problems fixed :)

In my present location (at work) my ubuntu machine can't connect through ethernet.

Hi, I'm new to Linux, Ubuntu and to this forum, I checked some of the other posts already to see if any of them would solve my problem and I haven't been able to figure it out.

I installed Ubuntu 10.04 a couple of months ago and haven't had many problems till today when the internet suddenly stopped working.

Just installed Ubuntu 12.04 a couple of weeks ago on my HP laptop (completely replaced Windows). Everything seemed fine until a few days ago when I was unable to connect to the internet with my wireless network at home. I also tried three other wireless networks and also tried to connect by ethernet cable. These are all networks that I have been able to connect to in the past with no problems.
