That's caught me out before, some of our routers at work are connected to PCs with a CAT5 type cable from the router to a 9pin D to RJ45 adaptor and sure enough they didn't appear to be wired right. Then there's the Power Over Ethernet standards too which complicates things more (we have specially wired Brown cables for our Cisco Phones at work).
