Bit confused with Mbps speeds

[Zephiux]

After doing speed tests with both ethernet and wifi connection, my download speed is on average around 6 to 6.50 Mbps and upload speed around 1 Mbps. My ping around 15-30 ms. Now my wireless router supports up to 300 Mbps on each dual band channel. So if Im understanding this correctly, my Internet speed is around 6 Mbps from my ISP and my router would support 300 Mbps of that? So basically my ISP speed is extremely low with todays standards with my current plan? Do many people actually max out transfer speeds such as for example 300Mbps with their ISP? That would seem insane. Anyways sorry if these are very stupid questions, which they probably are. I'm just a bit confused because many wireless routers/adapters support up to speeds like 150,300, 450, etc Mbps speeds, while it seems mine is extremely lower than that according to speed test, yet my speeds are very acceptable for video streaming/gaming/ etc.

6Mbps is what your ISP provides. Your house talking to the outside world. Kinda slow by todays standards, but not critically so.

You routers "300Mbps" is strictly between you and the router, not you and the outside world. And that is a theoretical max.
That is possibly beneficial if you are moving files between devices inside your LAN.

So does that mean that my 300 Mbps router wouldn't make my wifi faster than say a 150 Mbps transfer rate and would only be beneficial if I was using LAN? If I'm getting this correct, that means that the 6Mbps that my ISP provides is not the same type of speed referring to a 300 Mbps router? I'm assuming that would be the same with a wireless adapter.

Correct. Talking to the outside world, you will only see 6Mbps max.

For instance, I have a 50/50 fiber connection. I get ~55Mbps from Speedtest.net.
My LAN adapter is 1000Mbps. That is wired to the router. I still only get that same ~55Mbps to outside.
Inside my LAN, talking to other devices, it is 1000Mbps.

Your WiFi is a whole different thing that what your ISP provides. 150, 300, 450...that is all internal wireless, between you and the router. If you are wired to the router, you are probably getting 1000Mbps to the router (and other devices capable of that performance).
