So, from the great wifi experience with Premier Inn earlier this week, to today’s naff one with BA.
I’m in BA’s lounge at Gatwick, and using their wifi service. Yes, it’s free, but it really is shockingly slow.

Let’s take a quick look at the radio spectrum with Wifi Explorer…

There’s an uncongested 5GHz spectrum, and the networks which are visible are all originated from the same three Aruba radio heads, so even though there’s multiple SSIDs on the same channels, at least they are orchestrated.
2.4GHz is a somewhat different story.

However the one which really has earned the “slap” has to be the “wide” 2.4GHz signal…

Apparently, the staff at the No1 lounge think their own wifi is so bad, they have brought in their own DrayTek access point and are happily stomping over 60% of the 2.4GHz spectrum with their ridiculous wide signal.
It might be free wifi here, but it’s barely useable. š¦
