I can't get Firefox, Iceape to recognize my wireless signal with Linksys wusb54g v4
I am using a Gateway laptop computer with Ubuntu 7.10. I am trying to connect with Linksys wusb54g v4 adapter. I get all of the bells and whistles. I show signals for all available WiFi signals, and try to connect to the Public ones with no encription. I get the info on the network terminal. I also have RuilT WLAN Manager which will show an active connection. Then I try to open Firefox or Iceape and it does not recognize the signal. I use Mycopper.net as my home page.
What am I missing in making the connection between my WiFi and my browser or email?
Any help would be appreciated.
