I play games like smash bros ultimate and Dauntless, both on switch, but every time I play I can notice considerable lag at times, I've tried switching my WIFI to 5ghz connection and upgrading to a faster network which gets me to 30mbs download speed, and a fluctuating >1-15mbps upload speed, I haven't tried getting a wired connection because it would be difficult to get the ethernet cord from my switch to my router, and I have friends who do use a wired connection and also complain about lag, is there anything I could do to decrease lag?
