Imac not detecting wifi

I hate asking questions like this because their are so many variables but it is driving me insaine and I dont know what to do. About 2 months ago I noticed my imac would randomly stop connecting to internet mid-use. I didnt think much of it the first time because sometimes our internet goes out. However, it started happening more and more and non of my other devices are effected (Windows laptop, Iphone, apple tv, ps3). The Imac shows its connected to my wifi in the corner but when you try to load a page it says its not connected. Once this happens and I try to click the network diagnostics tab in the safari error message and after selecting my wifi network (which shows up as available) I get a message saying "Everything appears to be okay". But when you go back to launch safari, gmail, itunes or anything else that uses internet it wont connect.

The one way I found to overcome this is to go through the full internet reconnection process by unplugging my wifi router and setting up my wifi again on the imac. The internet will work for a few days before I get the same problems randomly again. Its getting very frustrating and as I mentioned before non of my other devices are experiencing this! Please Help!

Mac OS X (10.6.3)

Use Software Update or the OS 10.6.8 combo update to update your OS. Also, update everything SU has to offer for your computer. When done, repair permissions and restart your computer.

===============

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.

Research Knowledge Base for network problems that pertain to the OS that is currently installed on your computer. See these basic networking KB Articles: http://support.apple.com/kb/HT1401 AirPort troubleshooting guide

Also, run the Airport Utility app which is located inside the Utilities folder.

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.

Yes you can if you connect through ethernet. You made no mention in your original post that you are unable to do so.
