no not at all
My in-laws have the same issue is the reason I asked. It was caused by their TV Setup. The TV is configured by a mobile app and I had to connect their phone to it. The second network was from that WiFi direct connection. The TV will let you attach on it’s own little router. It may be from a printer or some other similar device. I haven’t bothered to track it down yet. They have a NETGEAR AC1900 router.
Then again it might be the Chinese.
