my imac duo core, 2ghz, 2gig ram started slowing down a few months ago. it is connected by airport extreme router. the airport signal shows half of what it used to be but nothing has changed from before. if fact i brought my macbook pro right next to it and that has full strength and fast browsing. speed tests at the same site shows 400kbs-800kbs for the i mac, and over 2mbs for the macbook pro. in the same location and 30 seconds apart. both are running os 10.5.6
can the internal antenna go bad? or is there something i'm not cleaning out right?
 
Have you ever run maintenance on the Mac? if you haven't download either YASU or Onyx and run all the cleaning utilities. Once the maintenance Mac's startup/shutdown cache.

Doing software maintenance once every two months is the smart way to keep OS X running straight a new like (excluding hardware issues).
