Ubuntu 11.04 wireless connection problem
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.
