I hope this is the right place to ask this:

I intend to buy a new router, but now I am confused about the difference between dBm and dBi.

I have have two routers in head, one of them is **2dBi** and the second one is **20dBm**.

**Which one has better range?**

**Could you give me how many percent is the range of one of them in compare to the other one?**

And how that conversion can be done and how to estimate the range depending on those given numbers?

### Edtied:

The two routers are: `TP-Link-TL-WR1043ND-V3`

and `GL-MT300A`

What I need is to know which router has bigger WiFi range?
