When you’ve updated the driver, then you will need to go ahead, launch Diablo Immortal and see if that helped to resolve the issue.

If you have a third-party security program installed, then you need to put it into a game mode or a passive mode, then launch the game and see if that helped. If it didn’t, then disable your security software for a short period of time, and if it works, then you need to add the game to the exception just keep in mind that you’re not protected from security threats while it’s disabled.

But if you’re not able to use an ethernet cable, then you must try moving closer to the router and if it’s not possible, then you can always try using a wi-fi booster. However, sometimes these can also cause issues so if you’re already using a wi-fi booster, then try not to use the wi-fi booster and see if that helped. After that, restart your router and launch the game and see if that helped.
