Internet...browser can't find host server

Asked by Mr. Evans

my computer is linked into a wireless network, (which is giving me problems) but it says it is connected and is giving me a signal strength but whenever i go and try and go to a website it displays "The browser could not find the host server for the provided address." i have tried going to multiple websites, ubuntu.com, hotmail.com wikipedia.org, yahoo.com and mozilla.com and everytime it brings up the same message. I have tried to ping yahoo.com in the terminal but it said "unknown host yahoo.com" ran an ifconfig and printed out the following results, i don't know what they mean and was wondering if you could help

thank you for your time(hope you can help me)

Hi
I don't know if this can help.
When i had problems with connecting to a wireless network, i removed network manager and installed wicd. This you can do from synaptic.
Good day

the problem im having with that is that i cannot download/install any new synaptic packages, it is only showing the ones i have already downloaded and installed and when i search for new ones it is only searching the ones i have, so i don't know whats goin on. and everything in the 'Package' drop down menu is "grayed" out.

The problem I see here is that there is no IP address listed for your wireless or wired network connections. Simply dumping NetworkManager for WICD may not be the solution here. There may be an underlying network or configuration problem here.

If you have tried to manually configure your wireless network settings, be sure you provided a proper IP address, with a netmask and gateway address. Also be sure you supplied DNS servers to look up network names with. If you are using DHCP (dynamic addresses), make sure your DHCP server is actually giving out an address to your computer.

Finally, be sure your wireless card is connecting to the network you think it should be. The easiest way to do this is to hover the mouse over the network strength meter and see which SSID it says you are connected to. Mine, for instance, says "Wireless network connection to 'DrDabbles' (100%)". My network SSID is "DrDabbles" in this case.

In the end, you may be experiencing a legitimate problem with NetworkManager. If this is the case, you should view the contents of your system logs by clicking on "System", "Administration", and "System Log". Once that program opens, click on the "syslog" item on the left side, and look for "NetworkManager" entries. This should give you some information about what is happening.

To install additional packages, you will need a network connection. If your WiFi isn't working, you will need to plug into the network, update the package list, and then install any software you need.
