ANSWERED Fiber Connection & Low VPN Performance

[Kunuyana 8]

Hey guys

I have been a AirVPN user (with Eddie) for many years now and recently switched to a fiber connection internet to improve speeds. But suddenly every server is very slow and the ping is all over the place. It gets so bad that even Youtube is buffering even though I have a 300Mbit connection without VPN and no issues once I turn them off. This seems to especially affect Netherland servers, Switzerland servers are a bit better. I also have a current 3000+$ high end setup, so performance is no bottleneck for encryption.

- The issue also happens on my Ipad Pro as well as my Windows PC

I read in a different post (from 2020) that AirVPN had issues with fiber connection in general. Was this fixed by now?

Thank you

There were none, though, at least not on AirVPN's side. I'm reading it occasionally still but believe it to be provider-specific. I mean, I'm on fiber now and I don't experience any slowdowns.
What's your ISP?

[Kunuyana 8]

Thanks for your reply. It might be provider specific, that's true.

To give a concrete example. This is the speed without VPN:



And this is Crater (Netherlands) speedtest. Three times within a few minutes:



Especially the 1Mbit...like. The heck?

I've been a DTAG customer for 5 years now, first DSL, now Fiber, and there never were any kind of slowdowns.
This is Cujam, 10 ms to server, with Eddie and OpenVPN, connect via IPv6:

Provide a system report at your convenience so that your config is better understood.

we have this exact complaint at work frequently using Palo Alto.
here is what I have had to personally do to keep the users happy.
remove / Uninstall in this case Eddie.   and under network adapters remove the tap adapter or I guess Win? adapter installed by Eddie and reboot.   reinstall a fresh copy of Eddie.    and I have never had the user complain again. 
hope that helps

Thanks, I'll try that out if the system report shows now issues

@OpenSourcerer

That's good to know. Then maybe some of my configuration is wrong?

Here is the system report: (Link Removed)

This is another speedtest with Crater Server vs normal speed when I created the report. A bit better than yesterday but still 70-80% speed loss:

DNS Suffix Search List. . . . . . : speedport.ip

Oh, alright, you're using the Telekom-provided router. This is a possible source of issues. I'm not overly familiar with them, but could you check whether things like "UDP flood control", "Quality of Service" or similarly named options are enabled?

[iwih2gk 94]

Just confirming that it must be an ISP or hardware issue.  I am on fiber and using multiple
AirVpn relays in a chain (thousands of miles long through 3 different countries).  I am still getting just under 500 meg.  That is NOT counting when I am also going through 3 TOR relays such as now making this post.

Hey, so I checked all the settings and there are only the standard ones. Port control, power usage for wlan, ipv6 reset times, things like that.

May I ask what router you are using? I could buy that one too

And might there be a software aside from Eddie that could work better? What's important for me is this network lock feature so all apps use the VPN

Fritz!Box 5590. But a 5530 is also sufficient if money is a factor.

Network Lock is only implemented in AirVPN software. Others are building their own firewall rules for whichever system/firewall combo they're using: Windows Firewall Control, ufw on Linux, pf on *BSD and others.

Hey

So I just did some more tests when looking up the Fritzbox and with "Alphard" I suddenly got perfect speeds (the 300mbit test). Then I tried out Crater again and got the low speed result.

This would mean that it is not a router-hardware issue after all though? But a VPN server issue, right?

[OpenSourcerer 1441]

It looked interesting at first. This is Alphard via OpenVPN, this time on my tower (with a 2.5 GbE port, whereas my ThinkPad was a 2.5 GbE port via Thunderbolt 3). 75% down, close to 100% up.

But then I did Crater via OpenVPN.

So for you both work fine... weird. I redid the speedtests on Alphard multiple times now, always perfect speed. Maybe it's some incompatibility elsewhere, but it's definitely not a ISP block or router-hardware issue, otherwise all servers would be slow.

The one difference I spotted is that one is by "PhoenixNAP Global IT Services" and  the slow one by Labixe Ltd. Do you think that could matter?

[OpenSourcerer 1441]

I would always test the performance of whatever I want to perform over VPN, where it's supposed to perform. To give an example, if I want quick Steam downloads, test the servers with a Steam download. Speedtests, as you probably noticed, depend quite a bit on the server the speedtest software selects. Take them with heaps of salt and always test under real workloads.

[Kunuyana 8]

Tried it out with steam, similar result. One is much faster than the other. I guess I just have to find the golden servers and stick with them, that's fine really

Thanks a lot for your help OpenSourcer

[Kunuyana 8]

Just a little update for those having similar issues. I tried updating Eddie to the experimental version 2.24.4 and it significantly improved speed and connection consistency as well as ping stability. Definitely worth trying out
