Hello,

I recently purchased 1 Archer BE3600 and 2 Archer AX18 units. The BE3600 is the main router, and the 2 AX18 units are satellites. Everything is connected via EasyMesh (wirelessly).

The setup goes very smoothly and the network works perfectly for 12–24 hours. Then, for no clearly identified reason, several situations occur either separately or at the same time:

• One of the satellites (AX18) disconnects and does not reconnect unless I restart either it or the main router.
• The network crashes completely or partially. It only starts working again when I restart the main router.
• The network becomes slow, some devices disconnect while others do not, etc. I have to restart the main router to fix the problem.
   

Some useful information:
 

• Both satellites have a very decent connection to the main router (3 blue bars out of 5).
• Smart Connect, TWT, and OFDMA/MU-MIMO are disabled (same issue when they are enabled).
• All drivers and firmware are up to date everywhere.
• I have already tried resetting the routers and adding them again.
• I tried using the BE3600 with only one AX18, then the other AX18.
• There are no other Wi-Fi networks in the house, and my house is far from any other house.
   

At this point, I have no other idea left. Does anyone have an idea? Or shall I just sent all of this back to Amazon.....?
