Hi,
My setup is the following. Using a DS218+ with 2 Hdds in RAID 1. All connections are by cable 1000mbps.
1st test: Download using the map netwrk drive in windows 10. I added the drive in my explorer. Speed: 45-48MB/s.
2nd test: Download by using chrome browser, logging in and using File...
Ai Mesh has something very useful : it handles roaming, the device is always connected to the router that has the best signal.
The ac66ub1 has gigabit internal switch.
I have an Ai Mesh setup which is explained in the diagram. The question is why do I have only 500mbps on the nodes through cable connection . I tested all three nodes and all behave the same. I also tested all other cables and outlets and all work fine.
