I have wireguard installed on my router. I want to test the internet broadband speed online. On visiting various sites, the speed cannot be measured because the sites are :trying to find the optimal server, which they have not, hence they cannot ping me.
How do I solve this.
speedtest.net (ookla) and also iperf are working with wireguard.
When I assign my wireguard Router as gateway, the connected device is able to test speed.
When I start up the wireguard app on android devices of mine, also no problem.

I can use speedtest.net and DSLReports.com without a problem connected to KeepSolid Engeland
First make sure you are connected and use ipleak.net or the likes to see if you have the IP addres of the keepsolid server.
I can think of three problems, if you are using PBR than your DNS goes out via the WAN (there is a trick for that)
MTU problems are possible but then you would notice very slow loading or stuttering, see the guide under troubleshooting.
But the most likely it is a browser problem, Firefox and probably Chrome are starting to use DNS over https with Cloudfare? as DNS provider so check that or try another browser
Along with the above and changing the MTU to 1431, I was able to get the download speed from wireguard that I am paying for from my isp. That is great when compared to openvpn client which give me a max of a third.
Caveat; when comparing speed, wireguard used my isp server but openvpn client gives a server closest to your assigned ip address. How does this compare; it looks you are comparing apples with oranges.
What is your take on this? Is there really a material difference in speed between the two or are you being hood-winked?
Further research revealed the download speed of wireguard can be twice as fast as openvpn.
