R1 is the only router with 1 Gbps ports. Everything is auto except 1 connection that requires manual settings.
*R1* -- (Auto 1 G FD) ...Internet... (Manual 100 FD) -- *R2 *-- (Auto 100 FD) -- *R3* -- (Auto 100 FD) ...M5... (Auto 100 FD) -- *R4* MTU is set to 1500 on every port (and the UBNT link). Flow control is off, and none of the interfaces show any pause frames received. This is a live link, but it is only running ~ 1 Mbps otherwise.
