    • Since 3 days extreme slow write to NAS, only via 5Ghz Wifi, mystery that I can not solve

      Hallo there,

      I enjoy using OMV for a couple of years already.
      Never ever any problems, till 3 days ago.

      I didn't change anything in the configurations:
      - I have mode connected to the router (1Gbit) Netgear Nighthawk r8000 (tri band),
      - The OMV is Banana-pi based, wired to the router 1Gbit,
      - there is also mirror disk HDD wired to the router USB3.0,
      - i use 3 WIfi's (2x 5GHz and 1x 2,4Ghz),
      - computer can be wired to the router (1Gbit),

      The situation now is as follows:
      - If I try to write to NAS via WiFi 5Ghz it stuck/freezes/hags. Somethimes it reports very slow 50kbit/s write rate. I cannot even cancel the operation from Windows level,
      - read also via 5Ghz is perfect,
      - two (separate) 5GHz WiFi's exactly the same.
      - wired read/write perfect (same computer),
      - WiFi 2,4Ghz read write/perfect (same computer)

      I've tried already OMV-firstaid - no problems identified.
      I've updated Erasmus to the last version - no change.

      I'm totally lost. Can anyone help me to identify the problem?

      Kind regards to all community!
