did not want to believe it, but was disabused! The signal quality is often criticized here really an underground operation for the router. Have a lot of products from TP Link in use and was not always disappointed, super P / L ratio. The router should replace my TL-WR841ND, because I want to upgrade to Gigabit LAN. But my 841er has a 30-40% better signal quality in the 2.4 GHz range (with the same Installation Environment). Well, now goes back to the times and see if I get the WDR4900 low.
