Just be consistent on both ends.

So if you go auto on the 2801 do the same on the 2960. If you set the speed/duplex on the 2801 set it the same on the 2960.

Newer generation of Cisco products have better speed/duplex autonegotiation with each other. Just to test, boot one and check with the other that the speed and duplex is full/100 instead of half/100 or half/10.

Otherwise, like what Jon said, force BOTH sides.
