This depends. Most routers like those shipped with internet providers are capable of at least 100Mbps through LAN, so use LAN (a wired connection) as much as possible. https://twitter.com/amielitow_/status/1304732928497205248

With Wi-Fi, it's a bit more complicated. Most routers are capable of 2.4GHz b/g/n, with 'b' being 11Mbps and 'n' being 300Mbps theoretical max speed. The catch here is if you connect an old device that uses 'b' speeds, all your Wi-fi devices will run at 'b' speeds.

The Asus router in the picture (which is expensive and overkill for most of you) is "dual-band" meaning it's capable of simultaneously spitting out a 5GHz signal which is generally faster & less prone to interference, but with shorter range. That's another factor.

Don't spend money on a fancy router if you don't need to!

If you really need it, there are cheaper 5GHz routers out there like this one: https://shopee.ph/TP-Link-ARCHER-A6-AC1200-Wireless-MU-MIMO-Gigabit-Router-Dual-Band-WiFi-Router-TP-LINK-TPLINK-i.117867014.2422734687
