So switching to a slower wifi AP causes packets destined for outside of your network to not be dropped? That sounds like one of those cursed issues that’s a complete nightmare to track down lol. Maybe the faster speed of the 5.8ghz network is causing your router to get overwhelmed or something? Does the same issue happen if you connect via ethernet? I don’t really know what else can cause this, I hope you can get it fixed!
