Flint ax1800 Open VPN speedI

My Flint ax1800 has Open VPN speeds of 70Mbps (wired) and 50-60 Mbps (wifi on 5G) with Adguard Home and DNS rebinding switched on. My internet connection is 100 Mbps. I recently upgraded to 200 Mbps and was hoping my Open VPN speeds would increse but they stayed the same. Is there a way to increase my Open VPN speeds? Any suggestions? Thanks for your help.

The maximum speed for OpenVPN on Flint is 112Mbps. if you need higher speeds, we recommend you try WireGuard, which can reach 500Mbps.

Wireguard gets me 90 Mbps (Windscribe) at best. Before and after the speed upgrade. Im using wired connection. Wifi on 5Ghz gets me 50Mbps on Open VPN and 70Mbps on Wireguard. I dont know if i need to tweak something on the Flint router. Thanks

There is usually nothing that requires additional configuration. Maybe you could disable ADGuard Home and try again?
VPN speed also depends on the location of your provider’s VPN server. Have you tried a different server? If you disable VPN on the router and use Windscribe on a PC connected to the router via a network cable, can it get close to 200 Mbps?

Disabling vpn gets me 200 Mbps. I did try different servers for both wireguard and open vpn (Nord) and get the same result. Sometimes even lower. Was thinking of upgrading to beta firmware 4.1 but i get a warning that its an old firmware so did not do it.

If you use Nord actually the ovpn speed can be easily 150Mbps+ and wireguard speed up to 600Mbps.

But this require you to test using the server that is near you. If you use a server that is far from you the speed can be much lower.

Thanks for your tike. Maybe ill just stick wiith the speed im getting right now. Maybe a future firmware uodate may fix it.

Can you try running the same VPN on your Desktop/Laptop just to get a better reference of what is possible with your internet connection?

So instead of the Flint doing the VPN client connection, do it on a powerful PC/Laptop just as a test. If that gets you the same result, it might possibly be something between your ISP and the VPN server causing the bottleneck.

Dont have a powerful pc or laptop to do that test. I have an old asus laptop that can only connect to a 2.4 Ghz wifi and wired connection yield the same results. Maybe it is between my ISP. & VPN.

Since you had stated that you get 200Mbps when VPN is disabled, I doubt it is an ISP problem. It is unlikely that your ISP would be detecting VPN in order to throttle because there are very many people using commercial VPN providers (e.g., NordVPN, ExpressVPN, PIA, etc.) that get high speeds. You can always ask your ISP whether they have a policy on VPN. You can also test with VPN client on a smartphone, which are really powerful nowadays.

I do not work for and I do not have formal association with GL.iNet

The Flint would generally cause a slowdown for OpenVPN if its processor/soc cannot encrypt/decrypt data quick enough. In this case the processor/soc should be able to do more than is being achieved. To avoid that Flint’s processor/soc being the issue I therefore asked to run the OpenVPN client on a PC/Laptop, which has a processor way more powerful than a Flint has. That did not change the result which point me into the directory that somewhere in the connectivity between OpenVPN client <—> OpenVPN server <—> Speedtest server there has to be some issue.

It could be bad peering at the VPN’s datacenter (cheap bandwidth for more profit), it could be the VPN providers limiting speedtests, it can be plenty of things. Given the current results I just doubt the Flint is the bottleneck.

Thank you all for the input. Borrowed my sister’s Samsung smartphone and windscribe (wireguard) yielded better results (150 - 190 Mbps) compared to nord vpn (50 - 60 Mbps). I did try all of nord’s servers, the ones that connected anyway.

Very unlikely to be an ISP and/or VPN provider problem, given that both serve millions of customers. Very likely to be a Flint problem as evident by all the issues reported in this forum, so it is the first usual suspect to check. I suggested to try on a smartphone anyway, since no powerful PC.

In that case, explain the following:

The sister’s Samsung smartphone and windscribe (wireguard) yielded results of 150 - 190 Mbps
Nord vpn on any device yielded 50 - 60 Mbps.
No VPN used yielded results of 200 Mbps.

What would according to you cause the Flint to cause that bottleneck? In all these case the only thing the Flint is doing is routing traffic, just like it does when no VPN is used at all.

i am getting on flint and slate axt as well:
no vpn - 900+ mbps dl/ul wired / 650-700 mbps wireless
wireguard up (airvpn) - 600-650 mbps wired / 450-500 wireless


Smartphones still has limits on processing power, whereas Flint VPN is buggy.

What explains higher speeds without turning on VPN on the Flint?

Consider yourself lucky :rofl:

Somehow I get the feeling you are pretty hating the GL.iNet products for some reason. You also did not really give much arguments explaining how windscribe being quicker than nordvpn in identical situations is apparently caused by the Flint.

Given that I will from now on ignore you presence on this forum.

Me too with you I hope you get your 2.5Gbps Internet for your 40 x 4K TVs for Netflix.

EDIT: Make that 100 x 4K TVs for Netflix.
