Ubuntu 11.04 wireless connection problem

Link to this post 21 May 11

I have just installed Ubuntu 11.04 on a new computer which also has Windows XP installed. This computer is connected to the internet via a USB Zonet ZEW2590 802.11N wireless card with the Ralink RT3070 chipset.

Ubuntu sees the wireless card and it connected to my wireless router without any problems. When I look at the connection information it says the wireless card is connected at 24mb/s and one time it said it was connected at 54mb/s.

The problem is that when I go into Firefox and type in a url (such as www.yahoo.com) I see a message at the bottom of the screen saying "Looking Up WWW.YAHOO.COM and then it does nothing for several minutes. Then I get a pop-up box that says "Server Not Found".

Am I forgetting something in the setup?????

Thank you for any help you might be able to provide. I don't have much experience with Linux, so please try to keep any responses as simple as possible.

What are your network (TCP/IP) settings? Did you set them up manually, or get them via DHCP from a router (likely the latter).

try this command to see if your DNS has been configured/updated:

cat /etc/resolv.conf

you also need a route to get to the outside world. show the output of this:

route -n

also, how about showing your network configuration file contents?

cat /etc/network/interfaces
