Dramatic low speed on ASUS RT68U

[NWC31256 0]

Dear forum.
My ISP speed is 200Mbps fiber up/down.
My router is an ASUS RT68U, equiped with DD-WRT firmware version R41986, released on the 14th of this month.

When i folluw up the tutorial on then the speed is 40Mbps.
When i add a .ovpn on the openvpn app on windows, the speed is 220 Mbps.

Do i something wrong or is the touter not capable to handle this speed

Most probably. Though, that must be determined. What are your connection settings?

40mbit/s is actually a really good result with that router. The CPU is limiting.

No idea what you talking about. Where? ISP router or the ASUS.
My kodi box with an armel processor is showing the same behaviour..

I start to belief that some of my devices can not calculate the VPN.
Thanks anyway.

As in, server, port, protocol you are using to connect to AirVPN. Since you didn't provide logs.

None of the standard consumer level routers are going to do much, if any, better than that. They just can't handle anymore due to the end-to-end encryption. They're literally encrypting and decrypting each packet. The CPU's are the limiting factor.

Sounds roughly right the Asus rt68u has a slower cpu and no hardware AES (what openvpn requires really) for faster speeds of 200-230Mbps broadband speeds.

There is a post here explaining it better:

The asus RT-AC86U has 1.8ghz cpu with AES support and I can hit 200Mbps with it, has merlin firmware support and Airvpn has a guide also. Great router with easy policy routing and kill switch built in however does not support port forwarding while under VPN sadly.

Hi,

with Asus MerlinWRT you should be able to forward and pre-route packets from the tun interface of the router to the final IP address and port in your network through iptables rules. You can check whether the following guide is applicable to your firmware (access to iptables is necessary):
 
Kind regards

thanks air staff was not aware of that :)
