I think my router is fine because I don't have an issue with my laptop but my mac pro just doesn't connect to any given website once in maybe every 5 pages. If not that, it takes about 5-10 seconds to load up a page. All this happened out of the blue a few days ago. Could it be that my wifi card is malfunctioning? I have full bars on my wifi indicator at all times and i've used firefox and safari with the same results. i've also tried using a wired connection and it still doesn't help.
