Solves the problem of constant connection drops at 2.4 GHz.
9 July 2021 
Works in the Tricolor GS B528 set-top box at a 5 GHz frequency. Stable connection with Mikrotik hAP ac. No interference or unstable connection detected during device operation.
A small, compact device. It works stably both with a computer and with the Tricolor console. No complaints.
