Was flying YYC-HNL on a 7M8 over the weekend, noticed we were on FIN 501 so I had very high hopes for Wi-Fi, especially because I was running behind on work and could benefit from an hour of internet before we were over an ocean.
There was an announcement saying Wi-Fi was available after taking off, the SSID was broadcasting, and the IFE was advertising it.
Despite everything, I couldn't log in and use my pass, the splash screen told me to wait until later in the flight. I waited until after drink service (over the US border) to ask and the FA was very sure that all 7M8s weren't equipped with Wi-Fi.
Confused as to why she said that (their colleagues made an announcement to the contrary earlier), I panicked and said that we were "on FIN 501, which has internet", which is probably not the best wording when I could given a load of other evidence that Wi-Fi was available onboard.
Again, she reiterated "this type of aircraft doesn't have Wi-Fi"
15 minutes later, I asked the same question to the SD coming by and said "oh we just have to flip a switch for that" and sure enough I was online for the a solid ten minutes before we lost coverage over the ocean. Three of those minutes were navigating the archaic Wi-Fi pass login.
