title: Use your Raspberry Pi as WiFi router
---

Using [this guide](http://www.daveconroy.com/turn-your-raspberry-pi-into-a-wifi-hotspot-with-edimax-nano-usb-ew-7811un-rtl8188cus-chipset/) I successfully turned my Raspberry Pi with an Edimax WiFi dongle into a WiFi hotspot.
Here's how:

- setup customized hostapd
- setup dhcp server
- configure NAT

My network layout looked like this:

``` c
internet - router - Pi - tablet
             |
             |---- PC
```

Now the tablet is able to connect to the PC, but not the other way round.
To fix this, add a route to the PC's IP configuration:

``` bash
ip route add -net $PI_NETWORK netmask 255.255.255.0 gw $PI_IP
```

Replace `$PI_NETWORK` and `$PI_IP` with your own values.
