Hi guys!
I have a RB750Gr3 (giga) and a RB750r2 (fast) linked to the same CSS326 for testing purpose. The RB750Gr3 can handle the maximum Btest from a distant CCR behind the CSS326, but the RB750r2 only can achieve 40/60Mbps on the Btest results.. It negotiates 100Mbps Full normally. What can cause that issue? I have the same issue with an unmanaged switch on the same place of the RB750R2 (it's not directly the RB750r2 hardware..). I also see when I fix the advertise of the RB750Gr3 at 100Mbps, the same issue repeat.. Only 40/60Mbps on the Btest
