If it's new enough, it should be able to autosense MDI/MDIX and configure itself correctly.
The laptop may not be able to do this - have you tried the laptop on a different port on the router's switch?
If it still harfs on other ports on the switch/router, you might try a crossover cable if you have one handy, just for giggles.
It may be that the chip running the switch and the NIC don't want to play nice together - I've seen suchlike happen, but it's been years ago, before they started building everything with the ability to do autoMDI/MDIX configure.
Might make =absolutely= sure the cables are good - had some stealth-opens bite me in the arse before, too.
