The most correct thing would be to warn potential new buyers (not only friends and family) of this router about its shortcomings and limitations so that they do not spend their money. I think that today not having wireguard makes it a basic, obsolete and discontinued product.

I sold all 4x TP-Link routers and bought 4x G.L-i.n.e.t. 4x F.l.i.n.t 2. That was the best decision. OpenSource (OpenWRT) and as a customer you are not taken for a fool. The router has plenty of CPU power and lots of flash memory for additional applications. For 160€ in Germany at Amazon!
