Question: I have a a home network, pretty simple.

```
Internet <-> Modem <-> Router <-> Wireless Devices

```

But the thing is my house is pretty big and that setup is on the on the first floor, but the wireless signal doesn't get to the 2nd floor. I have another router lying around and I thought I could use it to give wireless network to the upper floor. 

Is this possible?

If it is I was thinking to do it like this:

```
                                            Router 2 (2nd floor) <-> wireless devices
Internet <-> Modem <-> Router 1 (1st floor) ||
                                            Wireless Devices

```

Is this right? There's a better way?

Thanks!

Answer: 
Disable the router function on the second one and use it just as a wireless access point. Set it to use the same DSSID as the first one and wire it down to the first one devices will seamlessly switch between the two depending on which has a stronger signal. Don't use the WAN port.

or wired network to the second floor to the second router but set the router to obtain dhcp then the second router will act like wifi network switch
