Recently, I installed Ubuntu desktop for it; before that it had automatically gained an IP address through DHCP. After installing Ubuntu desktop, I have provided an IP address as static but it is not obtaining that IP address. Instead, it is showing the DHCP address. When I check connection information, it is showing me the error message, "Error displaying connection information, no valid active connection found." I tried with ifconfig command but it shows the IP address as http://askubuntu.com/questions/572848/network-manager-not-working gained by DHCP but not the static one which I gave so I can browse the internet. I need to provide a static IP address. I have uploaded the error image. Please help me. network-manager share|improve this question edited Jan 13 '15 at 6:09 asked Jan 12 '15 at 14:11 vigneshwar 2915 How and where did you set up the static IP address? In Network Manager? –chili555 Jan 12 '15 at 15:04 I have attached two more images on that how i have added an ip address and its showing it has been never used. –vigneshwar Jan 13 '15 at 6:10 Are you quite sure the gateway is 192.168.1.50? Usually, the router address is xx.1 or xx.254. What is the gateway address in other devices on the same network? –chili555 Jan 13 '15 at 14:36 add a comment| 3 Answers 3 active oldest votes up vote 0 down vote If when using static IP addresses you are getting a problem with name resolution, you will have to specifiy specific dns (domain name servers) in order to translate URLs to IP addresses. sudo ifconfig

adding in our static IP details. But due to some internal changes I'm finding it more stable to make changes in the graphical interface…. nm-connection-editor, as these new changes are overwriting the file with some generated content. UPDATE: I have written some instructions on how to set a static IP in a more ‘Linux' fashion. Check them out here (for wired connections only) What do I need to set up a static IP? You need to add some details which you may not know of the top of your head: Your chosen IP Netmask Gateway DNS Server Where can I find these details? Your chosen IP Your router will most likely have a reserved range of IPs for static use, every domestic router I've used has reserved 100 - 200 (though you may have to check your router manual if you find its not). Netmask, Gateway and DNS Server Enter the following command in a terminal nm-tool The output will list the details of your network interfaces, wireless and wired. In the section of the [Wired] interface there are some IPv4 Settings that will look something like below: IPv4 Settings: Address: 192.168.1.67 Prefix: 24 (255.255.255.0) Gateway: 192.168.1.254 DNS: 192.168.1.254 Address - current IP address Prefix - the address inside the brackets is the netmask Gateway - this is the gateway, otherwise known as the default gateway DNS - is your current DNS server Setting the Static IP To the set the static IP run this command in a terminal: nm-connection-editor This will open the graphical network manager as seen below. If you have more than one connection, select the one you want to apply the static IP to, then click Edit. This will open the Editing Wired dialog. It is in this box that we need to enter the information we found earlier. In the box below you can see my default settings before applying my static IP. Each of the values can be edited by clicking
