You sure your cabling is good? I have seen this issue when there are 100 mbit/sec crossover cables involved (ie only crossing over two of the pairs) built or something similar. We use lots of 3550-12Ts to this day and they are still quite decent if they fit what you need.
In your position, I would probably blame it on cabling and start there with any investigation.
