I decided to create this tutorial because I facing a problem when I connected my GameShell in a Wireless that use the same network as usb-eth – 192.168.10.0/24 – thus generating problems such as IP conflict.

**Connect on your GameShell**

To do it is necessary to connect on GameShell via ssh, you can disconnect the wifi on GameShell and use just the interface usb-eth if you are on the wifi with this problem while you solve this issue.

> ~$ ssh [cpi@192.168.1.169](mailto:cpi@192.168.1.169)(your GameShell IP)

**Change the interface IP**

Edit the _/etc/network/interfaces_ file on the line usb0 _address_ , In this case I used a class A IP network rarely used _11.11.11.0/24_.

> ```
> cpi@DEOT:~$ sudo vim /etc/network/interfaces
> 
> ```

**from:**

> ```
> allow-hotplug usb0
> auto usb0
> iface usb0 inet static
> address 192.168.10.1
> netmask 255.255.255.0
> 
> ```

**to:**

> ```
> allow-hotplug usb0
> auto usb0
> iface usb0 inet static
> address 11.11.11.11
> netmask 255.255.255.0
> 
> ```

**Change DHCP range**

The GameShell use the _dhcp-server_ to make the connection easy, so its necessary to edit the file _/etc/dhcp/dhcpd.conf_ and change the range of IP that will be distributed, I chose a short range of IP _.100_ to _.105_, that is more than enough.

> ```
> cpi@DEOT:~$ sudo vim /etc/dhcp/dhcpd.conf 
> 
> ```

**from:**

> ```
> subnet 192.168.10.0 netmask 255.255.255.0 {
> range 192.168.10.10 192.168.10.250;
> }
> 
> ```

**to:**

> ```
> subnet 11.11.11.0 netmask 255.255.255.0 {
> range 11.11.11.100 11.11.11.105;
> 
> ```

**Change CONNECT script**

The _CONNET_ app shows the _USB-Ethernet_ interface IP as text, so it is necessary to make the change on the script manually. Edit the file _` __init__.py`_:

> cpi@DEOT:~$ sudo vim /home/cpi/launcher/Menu/GameShell/60\_CONNECT/` __init__ `.py

**from:**

> [“usb-eth-addr”,“192.168.10.1”, self.\_ListFontObj, self.\_URLColor]]

**to:**

> [“usb-eth-addr”,“11.11.11.11”, self.\_ListFontObj, self.\_URLColor]]

**— Restart you GameShell and test it!**

> ```
> cpi@DEOT:~$ sudo reboot
> 
> ```

**Check the UI on GameShell:**

> MENU \> CONNECT

**Connect a USB cable to test DHCP**

Connect a USB cable on the GameShell and check the usb-eth connection on your computer:

> ```
> :~$ sudo ifconfig
> 
> enp0s26u1u2 Link encap:Ethernet HWaddr ▀:▀:▀:▀:▀:▀  
> inet addr:11.11.11.103 Bcast:11.11.11.255 Mask:255.255.255.0

**Connect on GameShell to test the connection:**

> ```
> :~$ ssh cpi@11.11.11.11
>

> ```
