You say that both computers are identical but are both running the same background programs? Programs like anti-virus and malware can mess up the transfer.

Is one on the Internet while the other isn't?

You say they are the same computers but are you sure? Just because they have the same model number doesn't mean they have the identical components. If you look for your Dell model drivers I would bet that you have a choice of a number of them, at least based on my knowledge. I have worked on a number of Dell computers and it is always a PITA trying to find the right drivers out of the number listed for a given model number. This indicates to me that all Dells with the identical model numbers are not identical.
