Problem with the configuration of the vlan id on netgear orbi Orbi Pro 6 (SRX80) and slow internet

I have connected the orbi router to a ftth ont with 1gbps down and 100mbps upload, the connection use ppoe and a vlan id which i have configured on the orbi router. The router connects properly to internet, but i cannot use internet on my wired pcs but only on wifi, and the internet connection through wifi is stuck at 130 mbps instead of 400-800 mbps (which is the speed that i have on wifi with a netgear orbi router ax 4200) even though immediatelly after the reboot the wireless internet reaches speeds of up 500-800 mbps for a very short period of time before stucking at 130 mbps. What can i do? Is there a way to fix this problem?

This is the configuration
