Hi everyone, I'm using unifi 100mbps, I'm used ppoe mode connect with deco m4, when i connect with deco m4 i can get full speed which is 100mbps download and 56mbps upload speed. But if i connect with cable I only can get 60mbps download and 56 Mbps upload. I really don't know why download speed cant get 100mbps, u tried many ways already, the only way is use back the old router only can get full speed connect with cable. Have any solution?
