Lightning hit the router during a thunderstorm and it failed, I had an FM stereo radio unit from China for 7 euros and I decided to turn the router into a radio receiver. I used the board, since it has a power off button, I took the speakers from an old laptop, connected two lithium batteries in parallel, since this device works from 3-5 volts. So the antennas on the router are not receiving, but transmitting - I fixed a piece of antenna wire on one of the antennas of the router. On the radio board there are contacts for soldering power and speakers, everything is signed. On the left is the volume knob and on the right is the setting. The scale is digital.
