Why is my entire internet crashing when I disconnect from Blizzard games?
When your internet goes down, regardless of the trigger, it means that your network drivers or network hardware crashed. If you have this sort of problem, focus on things like:
- Network driver updates or firmware updates
- Power cycling your hardware
- Switching to an Ethernet cable connection
- Bypassing network hardware like routers
- Testing from a different network or a mobile tether*
- Replacing the device that is crashing
*Note: We do not support play on mobile internet connections. However if this works, it indicates the issue is likely with the modem, router, or ISP.
