Blocked at 585 Mbps après reinstall original Firmware. Good to you.
So what’s the issue? What kind of speed did you measured? How did you measure?
Please think about using a proper translation service so we will be able to understand the issue.
wireguard max speed 585 Mbps.
Good to you.
And what internet connection speed do you have? How do you connect? How did you measured the speed? Why did you install OpenWrt instead of stock firmware?
Turn off wireguard and what is your max speed?
