Hello,
Currently working in an ISP, and use large-scale RB 750 as the final router to clients in fiber. But in many cases, we have had complaints about falls and slow the network connection of these customers, which in these cases is after RB any of these network equipment: a firewall, Cisco RV042 (usually basically the whole family RV) SonicWall, FortiGate. We have already seen the door of negotiation issues, change Firmware, Firewall rules and can not identify any problems that may cause incompatibility with customer equipment.
Note: Using the RB2011u we do not have the problem presented in RB750, but is more used to RB750 to our customers.
I appreciate the understanding and the help that can be made.
Thanks
