Hello

I've bought a new a53 5G for the wife.

It has wifi connection isseus

It loses connection, or won't connect. Sometimes it says wrong password even after connecting to the wifi. The connection speed is also really slow

I've rebooted the deco's

Setup a geust network, both 2.4 and 5g on and off. No solution

Changed DHCP on ipv6

Turned off beamforming and fast roaming

Changed WPA settings

Turned off ipv6 and ipv4

RMA request for phone, approved. New one same isseus. I belive this is a firmware isseu on the deco. Can some one help me
