Koalaman 1 Posted ... Hi, So I'm Aussie and have my Raspberry Pi 4 now wired and am getting roughly 900mbit down and 45mbit up when NOT connected to AirVPN. I use Bluetit quick auto connect on startup and no matter which server I connect to the best I have seen for download speed is only around 60mbit. Sometimes. Upload speed is painfully slow. 2-8 mbit. Is this just something to be expected? I was hoping to somehow get at least 100mbit down ... Thank for your advice 1 zman3000 reacted to this Quote Share this post Link to post
zman3000 0 Posted ... I've also noticed horrific download and upload speeds today, I'm currently getting 850/45 speeds without using AIRVPN today, but using their servers I'm seeing speeds at 20/11(NZ), 100/18(Various US servers), and 240/12(Various SG servers). This is not the usual AIRVPN experience I'm used to, is something affecting the network today? Quote Share this post Link to post
Staff 9972 Posted ... @Koalaman Hello! Please try a connection over WireGuard and check whether performance improves. Note: AirVPN Suite 1.3 and older versions don't support WireGuard. The support has been added on the latest 2.0.0 alpha 2. You might test the latest Suite preview (if you feel adventurous) or you can try WireGuard userspace utilities directly, or you can run Eddie Linux edition. Please see here for the latest Suite 2.0.0 preview version:https://airvpn.org/forums/topic/56704-linux-airvpn-suite-200-preview-available/@zman3000 Since the problem in your case appeared suddenly, please open a ticket (to get official AirVPN support) and a thread of your own (for community support). In general, check here for the performance you can expect in AirVPN when no adverse conditions (for example traffic shaping by the ISP, MTU size problems etc. etc.) are met:https://airvpn.org/status/ Watch the "Top User Speed" table. Moreover, by checking the status page you can also have immediate and updated information on the infrastructure status, so you'll know whether some problem is affecting the infrastrucutre and/or specific servers. A screenshot of the table we mentioned to have a photo of the status of the infrastructure soon after you published the message: Kind regards Quote Share this post Link to post

Staff 9972 Posted ... @Koalaman Hello! Maybe connecting to Singapore (as it happened in your example) is not ideal from some Australia ISP. Can you please test specifically Japan, New Zealand and California (we mention California because there's a direct connection via a submarine cable between Australia and California, worth a try anyway). Also please set MTU to 1320 bytes in the [Interface] section of your WireGuard configuration file and check whether performance improves or not. MTU = 1320 You can edit the configuration file with any text editor. Re-run WireGuard to apply the change. Note: Bleutit 2.0.0 alpha 2 already sets WireGuard interface MTU to 1320 bytes by default (next release will let you set a custom value as well). Kind regards Quote Share this post Link to post
Koalaman 1 Posted ... Thank you for your support! I am now getting around constant 100mbit down via ethernet to my Pi connected to Asian servers, however not more - Is this to be expected? Secondly, no matter what I do, my upload is atrocious, used to be better when using AirVPN Suite, but not crazy better, UP always around 2mbit. Here's my .conf file for wireguard: ~ $ sudo cat /etc/wireguard/wg0.conf [Interface] Address = 10.15xxxx230/32, fd7d:76ee:exxxx2:d2a7:64a3/128 PrivateKey = XXXXXXXXXXX MTU = 1320 DNS = 8.8.8.8, 8.8.4.4 # Use Google's DNS servers or replace with your preferred DNS [Peer] PublicKey = xxxxxx PresharedKey = xxxxxx Endpoint = asia3.vpn.airdns.org:1637 AllowedIPs = 0.0.0.0/0, ::/0 # This will route all traffic through the VPN PersistentKeepalive = 15 Quote Share this post Link to post

Secondly, no matter what I do, my upload is atrocious, used to be better when using AirVPN Suite, but not crazy better, UP always around 2mbit. Hello! Both conditions are not expected. Now that the previous problem is resolved at least in download (yes, the upload seems even worse now, puzzling!), try to enlarge at small steps the MTU size. Start with 1340 bytes. If the performance improves, keep going up at small steps of 20 bytes maximum (1360, 1380...). As soon as performance decreases, go back to the previous step for optimum performance. Another factor to consider is packet errors caused by the physical layer, if the device is connected via WiFi. Unfortunately WireGuard's puny log does not help in this case, so try anyway to change channel and get a stronger WiFi signal (ignore if the Pi is already connected via Ethernet):https://www.metageek.com/training/resources/why-channels-1-6-11/ How is the upload band measured?

Staff 9972 Posted ... Hello! We don't deem those tests reliable at all. Why are they performed against servers in Malaysia (Kuala Lumpur and Puchong)? That's a questionable choice for our servers in New Zealand, Japan and Singapore. Try with comparison servers and VPN servers in the same country. The only correct choice was Sydney when you were not connected to the VPN. Trying OpenVPN makes sense in case WireGuard and/or UDP are shaped. In this latter case please make sure to test OpenVPN over TCP. Kind regards Quote Share this post Link to post

Staff 9972 Posted ... @Koalaman Hello! Very well! Now you can perform an additional, slight fine tuning, by modifying little by little (e.g. 5 bytes steps) the MTU size and checking for each value. Kind regards Quote Share this post Link to post

Staff 9972 Posted ... @Koalaman Hello! Even better now. And yes, 396 Mbit/s in download is expected from New Zealand servers (consider that on the server 2x bandwidth is needed). It's anyway a good performance in general in our infrastructure. The upload speed is very close to max capacity (40 Mbit/s) so it's perfect now. Kind regards Quote Share this post Link to post
