So i was playing Black Mesa and sister is yelling from another room that i should fix wireless connection. When i found out it’s the router that is dropping wireless i wanted to fix it. I started to change settings in router firmware and everytime i changed something wireless was fixed and stable again. And everytime I would alt+tab back to game sister would start yelling again. OMG let me play.
Ok what the hell… I started cmd on my laptop and started to ping -t. Back to game with alt+tab -> request timeout and general failure on cmd. I tested this many times now alt+tabbing in and out and wireless dies when i alt+tab back to the game. I can’t play the game without wireless crashing.
//EDIT
Things i tried and didn’t solve the problem:
-steam offline mode. Wireless drop as soon as i start the game.
-disabling lan controller on the PC where i run Black Mesa
-adding firewall exception to block hl.exe
