apex legends kills my internet

Having the same problem on PS4 Pro. Once I'm in a game, usually within 5 minutes of dropping, I'll suddenly lag out of the game. Returning to the PS4 home menu shows that the wifi is no longer connected. By going to network settings > test internet connection, I'm able to reestablish wifi and jump back into the game, but this usually takes at least a minute. Specifically, the wifi ONLY drops in an actual match, not in the lobby or at any other times. It also only drops once per match, and after I fix it, it doesn't occur for the rest of the game.

I've tried the usual steps of restarting the game, PS4, and router. PS4 is configured to only use 2.4GHz band for stability. No other devices on my network are dropping wifi, eg my wife will be playing Apex on PC at the same time without the issue. It seems like somehow the game is briefly turning off the wifi card in the PS4 itself...
