Q: Iphone 6 lags out during game play on wifi iPad works fine on same network

Hi lberra,

Thanks for using Apple Support Communities. Based on what you stated, it sounds like an app you are using may have a connection issue and is not playable. I would recommend that you read these articles, it may be an issue with the app itself or a connectivity issue.

If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support

Recommended settings for Wi-Fi routers and access points - Apple Support

Cheers,

Mario
