The article should have what you need. However as stated by AridLizard a live account and internet connection is required by some titles and this would also prevent any future updates to your console and games

Ok what type of connection you have? Broadband cable dsl or fibre?

Non broadband like satilite or LTE?

Mayhe we should troubleshoot the connection

Rather then saying im justgetting slow connection

Tell us the type and yes the type and which isp is important

If its bt or virgin those are known issues with their home hubs which actually needs replacing according to their own support

If its lte there is your issue

There is no solving that as its the connection not the service

It should be noted if you've have gigabit connections that doesnt apply to all of the net

To connect to the net you must go thru different nodes and not all are going to be 1gigabit

Will the update patch will improve the chance of getting game freezing and application failed to work.I rather play offline for my safety.

Some games require a connection to the internet; for example, Destiny 1 and 2.

Also, if I'm not mistaken, you need to sign into an Xbox Live or guest account to play games on the Xbox One.

With that in mind, you can play lots of games and modes offline.

And just an FYI, games will download / update slower if you're playing another game at the same time.

The ability to play offline has a lot to do with the game you are playing. Some games require Xbox live that have multiplayer while others have single player that can be played offline. its always best to check your title. Having your console as your
home console will ensure that you can play your digital games when you have no internet connection providing they don't require live
