I bought this router especially for sharing and Bandwidth management with Qos. When I activate the Qos the speed internet drops in all users (max 6) from 6mb to 0.6mb. (i know...6mb max for all) .
The Qos configuration page is generic and does not give you the possibility to do anything.
Also the cpu is many times 95% (without QOS!).
Buy the Router especially for the Qos and here we are with an unusable product.
I Use for years a TL-WR842ND with dd-wrt worked better and with Qos activated!
I know i can swap to dd-wrt but the procedure is not so simple with this version and the configuration of the double band and guest neither
Does anyone else have the same problem?

Regards
