My iMac's internet is super slow!!!!
I have several devices that are conected to the internet at any given time. Including an iPhone 5, iPad 2, iMac 21" and several other computers. All my devices are connected to the internet through an Airport extreme. My internet download speeds are consistantly around 20-25 mbps, however when I try to load a web page on my iMac its like its 10 years ago and I am using dial up. And while waiting for my iMac to load the page if I try to load the same page on either my iPad or iPhone it will load instantly. Again all of my devices are connected to the same Airport extreme.
At first I thought that it was Mediacom's crappy service but then I noticed that my other devices are working perfectly.
Please help, this is extremely annoying considering I use this computer for work and I need constant and fast internet for my job.
iMac, OS X Mountain Lion (10.8.2)
