Turning on Wireguard on RT-AX88U slows all local download speeds

What is your ISP line up/down at the WireGuard Server side?

Same w/o WireGuard. My problem was when enabling WireGuard server it would've halved my ISP speed on the router.

"Same" is not a number. 900Mbps at the client means you have Gigabit upload at the Server and Gigabit download at the client with nothing else using the connection on both ends. I'm trying to find if your VPN speed testing is clean and not a result of common IPv6 data leaks.

Ok. Then let me rephrase that....in the previous firmware update simply enabling the WireGuard VPN Server on the AX86U would've halved my ISP bandwidth with NO clients connected. This newer version doesn't have a similar behaviour.

I do get a speed penalty on the clients (Macbook Pro) at higher speeds when connecting via the WireGuard VPN client vs directly connecting but at least I can keep it enabled without incurring the overall speed handicap on the previous version.
