I see people asking about the difference between the TP-Link TL-WR841N and TL-WR841ND (sometimes they just ask TP-Link TL-WR841N vs TL-WR841ND). Since nobody else seems to have answered, I’ll take the question.
Here’s how to decode TP-Link model numbers. This is true of the 841 series, which is my go-to for the moment when I need a capable yet inexpensive router, but also other TP-Link models.
“TL” stands for TP-Link. “WR” stands for wireless router. The numbers tell you where the model stands in the product line. Beefier routers have larger numbers. “N” stands for the type of networking, which, in this case, is 802.11N. “D” stands for detachable antennae.
If you don’t need to be able to detach the antennae to replace them with bigger, longer-range models, you can save some money by buying the N-model. Otherwise, the TL-WR841N and TL-WR841ND are functionally identical. They both use the same DD-WRT build.
