Routers are like cars.

All cars have the same basic functions of getting you from point A to point B.

Some cars are small and slow and can only hold one or two people.

Some cars are large and fast and can hold 6-8 people.

Routers are similar to cars. Your internet depends on your router.

Some routers transmit data slow, some transmit it fast.

Some routers can support 1 connected device, some routers can support up to 15 connected devices.

Your internet experience is extremely dependent on the quality of your router.
