Hello,
I have an issue with my RT-AC3200 and 384.4_0 firmware.
WAN Port is been connected at 1Gbps, after update/reset.
The problem is that in less than 24 hours it falls at 100Mbps.
If I restart the router, it come back again at 1Gbps and so on.
This problem has appear after I have updated the router to 384.3_0.
I have hoped that this problem will be solved after I have update the router to 384.4_0 firmware, but it was not solved.
My internet connection is 1Gbps.
Is somebody having any ideea about how can I solve this problem?
Thank you,
This usually indicate an Ethernet cabling issue, as the port will downgrade the link rate if the connection isn't stable enough. I recommend replacing the Ethernet cable. This is definitely not a firmware issue, there's been almost no changes to the Ethernet port driver in years.
