I purchased an iMac at the start of September, it is the 24 inch model. It has been working fine until the past couple of days. My iMac it hooked up to my wireless router and sometimes when im on the internet the internet just won't load, mean while when i look at the airport icon it says im connect. The problem seems to fix its self when i restart the computer but then just comes back moments later. Any solutions? Thanks in advance
