This is giving me headaches.. I can't understand why I loose the very first packets when I wire my printer to the TP Link RE200
If you have any ideas to solve this issue, please let me know. I fear this is an incompatibility, I hope not...

I recently move a network printer (Dell 1320c) that was initially wired on an TP LINK AX50 to a place with no RJ45. I found in the TP LINK RE200 a great solution to bring this RJ45 option.

Until there, everything is going well, and I can even print (the target). Where I stuck, is that every first print fail, like if the system was awaking a bit to late.
Looking at a "ping -t" command to my printer, I can see the same situation occurring. 
Packets 2 & 3 are always lost, then system is responding. And then I can chain ping and it will works. 
This scheme repeats systematically after I leave it alone 1 minute.

ping -t 192.168.0.30

Here are some tries I already done :

• Changing RJ45 cable, and even routing it differently.. : same issue
• Static IP from router : Same issue
• Static IP defined from printer webpage : same issue
• Changing place / or  wifi strength settings : same issue
• Tried ping from 2 different computer (W10) : same issue
• Reboot as much as required : same issue
• Wire a computer on RE200 : works, neither packet lost, nor bandwidth speed decrease
• Wire printer directly to the TP Link AX50 (as before) : works like before
