I recently installed the Archer 5400 AXE5400.

Everything is connected fine except for the TV with AmazonFirestick.

The streams keep buffering for a very long time and sometimes the connection gets lost. Its connected with 5G

I have the QOS set as high Priority device and always on, the total bandwith is set to 300 and 300 which is provided by my ISP.

The connection type is Dynamic IP which is the auto connection.

Anyone have any suggestions to fix the issue
