An awareness campaign won't help. The problem is that people get some shitty router/AP provided for free by their ISP which they set up at the far end of the house on the same channel as fifty other shitty ISP-provided routers in range and then complain about their TikTok videos stalling. Once they switch to 4G all their problems go away, so they stay with 4G because that "works" and WiFi "doesn't work".
