I have Ubuntu 11.10 installed on my Acer and it connects to my wireless network no problem. The actual connection is fine and strong, but it won't let me browse the internet at all. I just get error messages saying "This web page is not available" and goes on to say the DNS look-up failed [whatever that means]. Sometimes I am lucky and it connects immediately. However most of the time I simply can't browse the internet at all and to say it is frustrating is an understatement. \n\nCan anyone help please?
