AX73 router PPPoE connection, slower speed than ISP modem
I bought today the AX73 router, I set my ISP modem to bridge mode. I checked the speed on ISP it's like 700 mpbs (I created PPPoE connection on my pc and connected the modem with cable). And when I check it on router via cable or wifi it gives me 300-320 mpbs (router is PPPoE connection as well).
What should I change to reach higher speed on router?
