Shoot marketing!
Many of these are consumer or small business electronics. Therefore should be named appropriately. That means that TEU751-a/ccrk400085r is a bloody useless name. Simple range name and number would be right. However 'Nighthawk' is perhaps even worse. Is it a stealth router? Does it sneak out at night and bang the neighbour's missus? Or is it just a bit of cheap black plastic stuck in a dusty corner?
They've managed it with printers. So why not routers or TVs? You can have a Thingyjet 3100 or 3200 and then they eventually get bored of the workings of the 3000, and go up to the Thingyjet 4000 range. Easy. Understandable. Everyone can find the bloddy driver software.
At least with TV models they have an excuse, in that they're deliberately trying to obfuscate things, to keep the retailers happy, so you can't compare the prices instore with those online. And so they can stick 'smart' gubbins on the same panel, and double the price. Why anyone wants the internet on their telly is utterly beyond me, but that's another story.
Router manufacturers have no excuse. Aaaargh!
