WiFi connection

Hello,

I recently acquired a Peloton Bike.  I've been having an issue that when my new bike goes into sleep mode, it will not auto connect to my internet when I wake it up.   I have to turn off the WiFi and turn it back on again (from the bike) for it to connect.   I contacted Peloton and they replaced my touchscreen.  I'm having the same issue with the replacement touchscreen leading to be believe that it's not the bike but my WiFi.  I rebooted my modem several time to no avail.   I am not having any issues with other devices on my WiFi.  They easily connect and stay connected or auto connect with any problems.  It's just the bike.  Peloton next stay is to ensure my whitelist my MAC address.   Is that something that can be done here?   Thank you
