Whenever possible, it's better to game over a wired (LAN) connection rather than using Wi-Fi, which is generally slower (depending on your distance to the router) and introduces higher latency. Being physically tethered to your router is not always convenient, though, and that's where Rivet Network's new Killer AX1650 wireless adapter might prove beneficial.

We have not had a chance to test this new adapter yet, but have spent time with previous generation Killer networking gear, with mixed results. In 2015, for example, we were of the opinion that motherboards with Killer adapters weren't worth the money. Slightly more recently, we found that a Killer NIC (network interface card) could make a big difference in some situations. Since then, we have not spent much time specifically testing with Killer gear.
