# Connecting to unencrypted WiFi networks
Remember that using an unencrypted WiFi network means anyone in range can read
your communication. Hence, we strongly recommend [using TLS for accessing the
gokrazy web interface and doing
updates](/userguide/tls-for-untrusted-networks/).
To make gokrazy connect to a WiFi network, first include the
`github.com/gokrazy/wifi` package in your `gokr-packer` command line, e.g.:
```shell
gokr-packer \
-tls=self-signed \
-update=yes \
github.com/gokrazy/hello \
github.com/gokrazy/breakglass \
github.com/gokrazy/serial-busybox \
github.com/gokrazy/wifi
```
Then, configure the `wifi` program by creating the file `wifi.json` on the
permanent data partition:
```shell
# The following assumes you already created a file system
# on the permanent data partition. Otherwise, please use:
# sudo mkfs.ext4 /dev/disk/by-partuuid/2e18c40c-04
sudo mount /dev/disk/by-partuuid/2e18c40c-04 /mnt
echo '{"ssid": "I/O Tee"}' | sudo tee /mnt/wifi.json
sudo umount /mnt
```
After starting gokrazy, the `wifi` program will connect to the WiFi network `I/O
Tee`:

## For debugging: known-working WiFi router setup
In case you have trouble getting your Raspberry Pi to connect to your network,
this is how I set up my [TP-LINK
TL-WDR4300](https://openwrt.org/toh/tp-link/tl-wdr4300) with [OpenWrt
19.07](https://openwrt.org/):

The MAC address filter isnt a security measure, but prevents others from
accidentally joining this open network.
