ANSWERED Bandwidth very low

[milkaca 1]

Hi, I only get around max. 25 Mbps for download. Why is it so slow? Tested on Netherlands servers, my location is in Germany.

 

Without VPN I get 150 Mbps. Any comment would be welcome.

how are you connecting to Airvpn?

[Jeremyx3 2]

1. Have you tried another server?

2. Have you changed the protocol and port to try something other than the automatic or default? Being SSL443 or SSH22?

3. I'll ask instead of assume, are you using Eddie? If not, like Air4141841 asked, how are you connecting?

[milkaca 1]

1. I always use Netherlands servers.

2. I always tried default only UDP 443, like already stated filter on Netherlands country.

3. I tired with OpenVPN for Android and Eddie latest stable version on Linux and Windows machine.

 

Any suggestions, what to try next?

Would you go on Eddie and change the protocol to SSL, 443, Entry IP 4. Then go to servers and pick any of the following: Errai, Hassaleh, Pleione, Alshat, Crater. I know the servers are fine as they are in the Top Users with people using 100mbits+ with each. 

 

If that doesn't do anything, try SSH, 22, Entry 3 or 4.

 

Also, what are you testing speed with? There are numerous tools and I highly doubt it would be a problem with them. But can you try another server on the tester? How about another tester? I know of several. https://speedtest.net/ https://testmy.net/ https://speedof.me/ https://fast.com/

Thank you for the feedback. Will try out as soon as I come home and will give you result. I was using speedtest.net so far.

Hi again, I tried all cases like you said and now I am getting 38 Mbps, what is higher but not much.

Hello!

 

You could check out some of the links near the bottom of this thread, regarding speed.

After long testing this is the best result so far: 49,88 Mbps

 

With TCP 80 entry 1.

 

I also added OVPN Directives:

mssfix 1432

sndbuf 524288

rcvbuf 524288

Use this and play around with the numbers 212992, 393216, 425984, and the one you already tried 524288. The push part makes a difference when using it on my router.

sndbuf 123456

rcvbuf 123456

push "sndbuf 123456"

push "rcvbuf 123456"

 

Try using UDP and the directive fast-io and see if it does anything for you, I don't really think it would but it's worth a shot?

 

Try changing the cipher? I've was told that you can't but you actually are able to. Just enter this:

cipher aes-128-cbc //use any cipher thats supported

ncp-disable //needed or you can't use a different cipher

Also if you want to test out which is fastest for you, here https://airvpn.org/topic/18322-how-to-quicly-test-theoretical-openvpn-throughput/

 

Could you try using Network Manager or CLI or whatever you use to connect to a config and see if it makes any difference?

Try Openvpn-GUI or whatever it's called with Windows?

Try Eddie for Android if you wanted, up to you on this one.

 

Try with another person's home internet and see if you get the same results?

 

Try some servers in different countries. 

 

Try a different VPN and see if it's the same problem? EDITED by Staff: deleted a specific, recommended VPN. No ads please.

What is the outcome of all of these things I suggested? 

 

If nothing helped.. I don't know what else to try. I would contact support. I'm not going to be anymore help! Sorry. I hope this does work though!

sndbuf 123456

rcvbuf 123456

push "sndbuf 123456"

push "rcvbuf 123456"

 

What kind of crazy numbers are these? Is this your password?

push is not needed, by the way. As client, you are listening for PUSH_REPLY, pulling the settings.

And I'd use 131072 byte instead as this is exactly 128 kiB. 2⁷.

 

I'd rather ask if you've got cable internet from Vodafone Kabel DE or Unitymedia. If yes, I found your problem: QoS. I've been fighting it for more than a year.

 

 

Try using UDP and the directive fast-io and see if it does anything for you, I don't really think it would but it's worth a shot?

 

5-10% CPU efficiency is what it does according to man. I don't see any improvement in throughput from this, but it doesn't seem to do any harm, either.

 

 

cipher aes-128-cbc //use any cipher thats supported

ncp-disable //needed or you can't use a different cipher

 

This will again cause less CPU cycles to be used for E/D, not necessarily an improvement in throughput and sure as hell no improvement in security. I'd leave them at AES-256-CBC without the ncp-disable directive.

 

You could try other clients but if you're a cable customer chances are you're not even the problem to begin with.

I am on Unitymedia cabel. What is your recommended setup, I would like to try this today with Eddie client?

I found the numbers on various sites. I NEED the push part for my openwrt setup or it doesn't successfully use them. It uses other numbers. So I do need them.

 

I'm just giving potential solutions, even bad solutions.

I don't use Eddie so my setup is different from yours.

You can configure everything in Eddie, like for example OVPN directives.

I use Eddie because of the network lock feature, I tried to use pure Open VPN but didn't manage to setup network lock script by applying IP rules on my Linux machine.

 

Anyway I will spend some more time to play around and try to get more bandwidth.

[milkaca 1]

Today another record in speed: 63,71.

 

This is the best setup in my case (so far):

sndbuf 524288

rcvbuf 524288

push "sndbuf 524288"

push "rcvbuf 524288"

fast-io

 

UDP 443 entry 3.

 

Thank you all for your support. I will try also suggested alternative to Eddie.

Well, same problem here. Everything runs fine for weeks / months. But since a few days i have bandwith problems while using VPN. Actually connected to Adhara, download speed is around 35 mbit. upload around 30 mbit.. my connection brings up to 95 mbit download and 38 mbit upload while outside the vpn. this happens every few days. what i do is then: open web-gui (merlin-wrt on asus ac86u). go to vpn tab -> vpn client -> disable vpn and enable after 1 minute again. so my router connects to another server in germany and everything is fine for a few hours (Using udp port 443 entry 3 for tls crypt). i just checked the traffic on adhara in these minutes - its fine. actually @70-80 mbit from 1000. so what could be my problem?

[annon3876 1]

It looks like thats an airvpn problem. Tested again while outside VPN. Downloadspeeds around 95 mbit and upload around 38 mbit. Then automatic connect to a germany server with udp entry 3. in this case mirzam. downloadspeed 2-5 mbit, upload actually under 1 mbit. tested then some servers directly.

Mirzam 2-5 mbit down under 1 mbit upload
Adhara and Errai the same
Tucana download 95 mbit upload under 1 mbit
Mesarthim 95mbit download 26mbit upload.

do others have same issues? 

[annon3876 1]

Noone has an idea?
