Bonsoir, Je viens à la pèche aux information pour avoir votre aide. J'ai un routeur Netgear WNDR4500V2 que j'ai flashé il y a peu avec la version compatible. (Micrologiciel: DD-WRT v3.0-r44715 giga (11/03/20))

La connexion avec mes informations NordVPN fonctionne mais en réalisant des tests je constate que quand mon tunnel est lancé mon débit est de 10meg montant et descendant. Quand je coupe le tunnel je suis à plus de 400meg (connexion Fibre).

J'ai testé le serveur en passant par le logiciel NordVPN et le débit est ok donc cela provient surement du routeur (Réglage ou limite matériel???). Je tourne en rond donc si vous avez une piste je suis preneur.

Merci d'avance à vous.

The CPU in that router (which I believe is 600MHz) is simply too underpowered to delivery any better performance w/ OpenVPN. If your firmware supports Wireguard, you'll probably see something better. But truth is, when you're dealing w/ these older MIPS routers, the VPN performance is abysmal. Even on my own ASUS RT-AC68U (arm, 800MHz, dual core), the best I get is about 30Mbps w/ OpenVPN (as high as 111Mbps w/ Wireguard though).
