RT-AC88U slowest then RT-AC68U, possible?

[murgal]

Hi! Im new

A buy a few months ago a new RT-AC68u, its works great, today i catch a AC88U and plug in to my network gateway and... Im disappointed...

In my lan i have a Synology NAS, on AC68U speed oscilate about 70-75MB/s download, on AC88U its only ... 67MB/s max, usulay 55-60MB/s.



Whats im doing wrong? I changed a few wirless settings on 88U and nothing change.

Mayby its broken?
