Model: Archer AX50 & TL-SG108E(UN) Ver. 4.0

Hello!

I would like to use link aggregation to enhance my network speed. The connection is as the following.

Internet <==> AX50 Port 3 & 4 (LAG) <==> TL-SG108E Port 1 & 2 (LAG) <==> NAS, PC, Printer...

After the setting and waiting around 3-5 minutes, the machines (NAS, PC, Printer) could get the IP address and link to internet. However, the network connection is not stable. The machines can't link internet after around 20-30 minutes and re-link to internet again. And, sometimes the speed is slower than without LAG (Only Giga Ehternet connection between AX50 and TL-SG108E).

My questions are:

1. Is my network connection correct? Can AX50 and TL-SG108E work normally when connect together by LAG? 

2. If the connection is correct, is there any step-by-step setting guide for setup LAG for this network connection?

Thanks a lot!

Ian
