How to reduce lag when online in Super Smash Bros.
Being late is arguably the worst thing that can happen to you while playing Super Smash Bros. Online.
A slow connection is often the difference between winning or losing a match. So have a stable Internet connection when playing Ultimate Online is important.
Nintendo’s servers also have nothing to write home about. Anything you can do to improve the experience — or at least make it more pleasant — will greatly benefit you while playing the game.
Make sure it’s really late
It sounds stupid, but testing your router to see if it’s laggy and not something else should be your priority.
Test your network bandwidth by turning off anything that might affect your connection, such as Twitch or Netflix. Restart your router and do everything in your power to make sure Smash Bros. is your priority when playing if you want to have a good time.
There are also methods related to change your MTU on your Switch, but we don’t recommend them because they can have negative effects if you’re not careful.
Buy a LAN adapter
Obviously, using a wireless connection can negatively affect you when playing online. Nintendo even makes a dedicated LAN adapter for Smash Bros. because the company knows that multiple players trying to connect at the same time will cause problems.
So if you’re next to an internet router and have some spare cash, it’s definitely helpful to get a LAN adapter if you can. find one in stock.
