internet connectivity

I am unable to get on certain websites with my imac... apple.com, comcast.net; but others load fine... amazon.com, etc. I also have a PC connected to the same network that loads all websites with no problem. Any ideas?

iMac (24-inch Mid 2007), Mac OS X (10.6.8), iPhoto ver. 8.1.2

Disconnect all devices from the computer then do the following:


Boot up from your Snow Leopard Install DVD while holding down the "c" key.

Select the language you wish to use, and then choose "Disk Utility" from the menu bar.

Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.

Once this process has been completed restart your computer and repair permissions directly from Disk Utility.


If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

If you are using your iMac wirelessly......

Try the basics first:

Change your router channel number. Most times this works & is all you have to do.


Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.


System Preferences>Network

Click the Assist Me button.

In the next window that pops up, click the Diagnostic button & do the necessary.

If using a Linksys router, contact LinkSys Customer Support and/or post in their forums.


If using Apple's Airport, please re-post over in one of the AirPort Forums.
