Why is one of the devices not connecting well via 2.4GHz Wi-Fi?

Question

WiFi

There is a Mikrotik RB951G router. Used in my apartment. At home, there are several smartphones on Android and iPhone 7. They have no problems connecting via Wi-Fi, but there is a laptop that connects via Wi-Fi only a meter from the router and then turns off after a couple of minutes.
The router configuration is below. Previously, there was another access point and somehow experimented with CAPsMAN, but it was taken out of the network. I checked the channels, the freest one was selected. Network card in a Qualcomm Atheros AR956x laptop.
