Refresh webpages

Hi,



I am using firefox v2, with a linksys WSUB11. Recently I encouter of loading webpages. Everytime after clicking a link or loading a page, I have to click the refresh button at least once before the pages actually loads. If not it would just show the "cannot be found" page. Why is this so?



Ps Help

Well, this would be my educated guess, your usb device isn't connecting fast enough to the router or there is a problem with firefox

ps. you wanted some help
