I just bought a brand new iMac 21" last wed. it's 2.9GHz 2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache and I added the fusion drive, with tax and everything it came a little over $2000. and I'm having a BIG problem. the internet connection is weird, to say the least. It's not just slow. 90% of the time I open a browser I get "failed to open the server does not respond" type of message. So far I have tried wireless ethernet connection changing DNS numbers (that I found on google) rebooting the modem and tried using different browsers such as firefox and chrome. I haven't tried any of the disk manager because it's a brand new computer. is there anything else I can try to see what the problem is? Internet itself cannot be a problem because I have a PC laptop and macbook pro that is just fine on wireless. I just feel like I have a defective computer. Please help.
