Voxel R7800 Voxel Internet Speed seems capped

[senpai]

Hello.
1st off I would like to thanks Voxel and Kamoj. I am new to Linux, so please bare with me.

I am on V1.0.2.80.4SF and have been having issues with internet speed when using OpenVPN (IPVanish). I have 2 devices connected and every report the same speed.
I get 30 - 35 mbps while using IPVanish on the routerand on a mobile device.
If I disable it I can get upto 250 mbps (i have comcast at 300+ )

the thing is, that when I run the IPVanish application on win10, I get close to 220 mbps. (this make my head hurt )

at this point I do not know for what else I need to look for and or change.

this is the .opvn:
client
dev tun
proto udp
remote iad-a03.ipvanish.com 443
resolv-retry infinite
nobind
persist-key
persist-tun
persist-remote-ip
ca ca.ipvanish.com.crt
verify-x509-name iad-a03.ipvanish.com name
auth-user-pass IPVanishVPN.auth
comp-lzo
verb 3
auth SHA256
cipher AES-256-CBC
keysize 256
tls-cipher TLS-DHE-RSA-WITH-AES-256-CBC-SHA:TLS-DHE-DSS-WITH-AES-256-CBC-SHA:TLS-RSA-WITH-AES-256-CBC-SHA


I did compare the logs when I connect via router with ipvanish enabled and running IPVanish thur app.
i did notice that snd and Rcv buffers were a bit different, but i have not found any why to actually change it.
I did change it in the /etc/init.d/openvpn-client file but that did not help.....

any way I thank everyone in advance for taking a look....

I'm also using IPvanish and also seeing that maximum download speed is around 35 Mbps.

Reason why your Win10 can reach much higher speeds, it because it has a much faster CPU than the router.

But, I did read that some people were getting OpenVPN speeds of 70 Mbps or even higher on a R7800 running Voxel FW.

My explanation for IPvanish not reaching this 70 Mbps: (don't have proof though)

OpenVPN client tries to set the send and receive buffers to 786432 to improve the speed.
(--sndbuf 786432 --rcvbuf 786432 in/etc/init.d/openvpn-client)

But if you connect to IPvanish, then their OpenVPN servers push a smaller buffer setting to the client:

(PUSH: Received control message: 'PUSH_REPLY,redirect-gateway def1 bypass-dhcp,dhcp-option DNS 198.18.0.1,dhcp-option DNS 198.18.0.2,rcvbuf 493216,sndbuf 493216,explicit-exit-notify 5,comp-lzo no,route-gateway 172.21.22.1,topology subnet,ping 20,ping-restart 40,ifconfig 172.21.xx.xxx 255.255.254.0,peer-id 6,cipher AES-256-GCM')

And perhaps also some other VPN providers use a cipher that is less strong?

Anyways, I'm only using the VPN tunnel to route my torrent traffic through it, so to lower speed isn't really bothering me.

EDIT: probably the pushing of "cipher AES-256-GCM" by IPvanish also has a great negative impact on the speed.

R. Gerrits thanks for the info.
I did some speed testing and it seems that on the 2.4 ghz channel i am getting 30-40 mbps on the Main router/modem (C7000). 5 ghz does 350 mbps.

it seems like the R7800 (Voxel firmware using Ipvanish) router some how is using the speed of the 2.4 even though i am on the 5ghz.

Without IPvanish I do get 240 - 250 mbps.
seems strange.

 

[R. Gerrits]

It is simply a coincide that your 2.4 Ghz WiFi and the IPvanish VPN both max-out at around 30-40 Mbps.

If I connect to my R7800 via 2.4 Wifi, then speedtest (without VPN) will get about 100 Mbps down.

thanks once again. Will continue to look.
