got my macbook 2-3 months ago. im running leopard, with parallels, 4gb of ram. everything is updated, including the new airport update i just received today. however, even before the update, i was having this issue. nothing has changed. havent done anything different, but in the past few days i have noticed this. it seems as though my airport is losing connectivity sporadicyl while im browsing, i will get pages that take forever to load, as in 10 seconds even. i am on broadband and everything was fine before. sometimes even, i am getting a roadrunner message when i got to a page that says the site im going to is not available. but if i go to my pc it is def there. it even gives me this message with google. ill literally click on a link that firefox will say "looking up .....com" at the bottom and it takes a while to load. if i open safari right then, it will also take a while to load the page. it usually blazes. i tested it at someone elses house on their wifi and it did the same thing. i have not tried the ethernet port, but i am fairly certain it is related to the airport, but it also my be some kind of dns issue on my mac. not sure. any help would be greatly appreciated.
