Hello. I have a problem with OpenVPN. The problem is that when I connect to my vpn provider, namely to ExpressVPN, I have a very low speed. I have already changed the vpn providers (ProtonVPN, VyprVPN) but it didn’t help. I also changed servers but the speed did not increase much.
Without VPN I have: 100 Mbit/s download and 100 Mbit/s upload.
With VPN I have 10 Mbit/s download and 10 Mbit/s upload.
I think that the problem is in my router, because if I connect through a computer (using the same server, and the same protocol) my speed is on average 75 Mbit /s
That's par for the course for the CPU in your router. It simply isn't powerful enough to do better, at least not with OpenVPN and AES-256 encryption as used by your VPN providers.
Well, I assumed that the power of my router is not enough, thanks for the answer. Can you suggest some good router with a powerful processor for vpn? There is also another question, if I use the WireGuard protocol on my router (TP-LINK ARCHER C60), will there be an increase in power? Does the WireGuard protocol require a lot of processor power to function properly?
You sound disappointed. Please know that it's not my (or I'm sure anyone's) intention to brush you off. I just really didn't want to open the n-th "which router is the best for me" discussion in a thread that started with a different question. I see you already started a thread over in the recommendations section.
