When I hover over the wifi icon I see I am connected to two wifi'




What if this "network 20" ?

I‘m no expert on technology but perhaps there are more than one Wi-Fi network options available at that gathering inn place? (eg: one network would be available for free but would be slightly slower than the rest, the other would require some sort of membership/subscription and would be faster, etc)
