After the most recent update, I cannot get Plex to open. The port refuses to connect. O have tried uninstalling and reinstalling plex and even going back to an older version that worked and it still doesn't work.

We tested this on TOS 7.0.1278 hardware. Your port isn't failing — it re-links fine at 5G. What's stuck is the data path (the MAC), which doesn't re-arm after your Mac's bus-powered adapter disappears overnight.

The main suspect is EEE (energy-saving Ethernet) at 5G: Realtek's own driver deliberately avoids advertising 5G EEE due to compatibility issues, but TOS ships it enabled.

Note: jumbo frames / MTU 8192 is almost certainly a red herring — a 42-byte ARP can't be affected by MTU, and your Mac captured 0 packets, meaning nothing ever left the NAS.

Please run this and leave it overnight:
Code: Select all
ethtool --set-eee eth1 eee off
Then power the Mac off/on as usual and check in the morning. Please report back:
Did traffic work without a down/up?
Output of
Code: Select all
ethtool --show-eee eth1
If it still fails, the
Code: Select all
dmesg
output covering the link flap
If this fixes it, we'll make the setting persistent.

EEE off did not fix it.

ethtool --set-eee eth1 eee off was applied yesterday and was still disabled this morning. After the Mac was powered off overnight and powered on again, ping 10.10.10.1 from the Mac failed with 100% packet loss. No interface reset was done before the test.

The last pair is the overnight cycle: link down when the bus-powered adapter powered off, link up at 5Gbps/Full the next morning. No MAC or PHY error is logged, but ARP/ping still failed until ip link set eth1 down/up. 5G EEE was not advertised, so this is not only an EEE advertisement issue. Please check the MAC re-arm path in r8169 after a long link-down.

Which drive bays on the F4-425 Pro are wired to the CPU’s native SATA controller, and which are wired to the ASMedia ASM1062?
The bays are numbered 1 to 4 from left to right when looking at the front. The power button is on the right, next to bay 4. Please say which bay numbers are on the CPU SATA ports and which are on the ASM1062.

Looking at the front of the unit (numbered 1 to 4 from left to right):

Bay 1 & Bay 2: Connected to the CPU's native SATA controller.

Bay 3 & Bay 4: Connected to the ASMedia controller.

Hope this helps!

Please perform the following verifications:

1. MTU verification: Change the MTU from 8192 to 1500 to determine whether the issue is related to Jumbo Frame configuration;
2. Link speed verification: Confirm whether the issue occurs only at 5Gbps, and test whether the same problem reproduces at 2500Mbps and 1000Mbps.
