			= Test that your Raspberry Pi can connect to the Experimental Router =
			To verify that your Raspberry Pi is connected to the experimental router with the 192.168.2.x subnet, you can perform a few simple checks. These checks will confirm whether the Raspberry Pi is using the expected network configuration. Here's how you can do it:

			==1. Check IP Address==
			The first step is to verify that your Raspberry Pi has an IP address in the 192.168.2.x range, which indicates it is connected to the experimental router.

			Run the following command to display the IP address of the wlan0 (WiFi) or eth0 (Ethernet) interface:

			<syntaxhighlight lang="bash">
			ip a
			</syntaxhighlight>

			Look for the inet line under the wlan0 or eth0 section. If you see something like this:

			<syntaxhighlight lang="bash">
			inet 192.168.2.x/24
			</syntaxhighlight>

			This confirms that your Raspberry Pi is connected to a router in the 192.168.2.x subnet. If you see an IP address in a different range (like 192.168.1.x), the Pi is connected to the wrong network.

			==2. Check Default Gateway==
			The default gateway is the router through which your Raspberry Pi sends traffic to other networks, such as the internet. To check if the gateway is your experimental router:

			<syntaxhighlight lang="bash">
			ip route
			</syntaxhighlight>

			You should see an output similar to this:

			<syntaxhighlight lang="bash">
			default via 192.168.2.1 dev wlan0
			</syntaxhighlight>

			* default via 192.168.2.1: This confirms that your Raspberry Pi is using the experimental router (which likely has the IP address 192.168.2.1) as the default gateway.
			* dev wlan0: This shows that the connection is via the WiFi interface (use eth0 for Ethernet).
			If the gateway IP is different (e.g., 192.168.1.1), then your Pi is connected to Router #1 instead.

			==3. Check Router Response with ping==
			You can ping the experimental router (192.168.2.1) to ensure that the Raspberry Pi is communicating with it correctly:

			<syntaxhighlight lang="bash">
			ping 192.168.2.1
			</syntaxhighlight>

			You should get a response like:

			<syntaxhighlight lang="bash">
			64 bytes from 192.168.2.1: icmp_seq=1 ttl=64 time=1.23 ms
			</syntaxhighlight>

			If you receive responses, the Raspberry Pi is successfully connected to the experimental router. If not, the connection might be to a different network.

			==4. Check Connected SSID (if using WiFi)==
			If your Raspberry Pi is connected to the experimental router via WiFi, you can check the SSID of the network to ensure it matches the experimental router’s SSID.

			<syntaxhighlight lang="bash">
			iwgetid
			</syntaxhighlight>

			The output will show something like:

			<syntaxhighlight lang="bash">
			wlan0 ESSID:"YourExperimentRouterSSID"
			</syntaxhighlight>

			This confirms the Raspberry Pi is connected to the correct WiFi network.

	To set up a static IP address on your Raspberry Pi so it ~~connects~~ to ~~a WiFi router (e.g., setting it to 192.168.~~2~~.2)~~, ~~you will need to modify the Raspberry Pi~~'s ~~network configuration. Below are the steps~~ to ~~achieve this~~:		If you have two routers at home, one for internet access (Router #1) and the other for experimentation (Router #2), and you want to set a static IP address for your Raspberry Pi only when it's connected to Router #2, here's how to handle it:

	== ~~Step 1~~: ~~Find Your Current Network Information~~ ==		== Scenario Overview:==
	~~Before configuring~~ the static IP, ~~find out your current network details, such as the gateway and DNS servers, by running the following command:~~		* Router #1: Used for internet access (e.g., 192.168.1.1)
			* Router #2: Used for experimentation (e.g., 192.168.2.1)
			* You want the Raspberry Pi to use a static IP (e.g., 192.168.2.2) when connected to Router #2.

	~~<syntaxhighlight lang~~=~~"bash">~~		==Plan:==
	~~ip r~~		* Configure the Raspberry Pi to have a static IP only when connected to Router #2's network.
	~~</syntaxhighlight>~~		* Ensure that when connected to Router #1, the Raspberry Pi continues to use dynamic IP (DHCP) for regular internet access.

	~~This command will output something like this:~~		==Steps to Set a Static IP for the Experimental Router Only==
			===1. Find Your Network Information for Router #2===

	~~<syntaxhighlight lang="bash">~~		You need the following network details from Router #2:
	~~default via 192.168.~~2~~.1 dev wlan0~~
	~~192.168.2.0/24 dev wlan0 proto dhcp src 192.168.2.45 metric 303~~
	~~</syntaxhighlight>~~

	~~In this example~~:		* Router (gateway) IP address: Likely 192.168.2.1
			* DNS server: Can be Router #2's IP or a public DNS like 8.8.8.8.
			* Subnet mask: /24 usually corresponds to 255.255.255.0.

	~~Gateway (router): 192.168.~~2.1		==2. Configure Static IP for Specific WiFi Network (Router #2)==
	Network ~~range: 192.168.~~2~~.0/24~~

	~~== Step 2: Modify~~ the ~~DHCP Client Configuration ==~~		The Raspberry Pi can be set to use different network configurations based on the WiFi network it connects to. This is done in the /etc/dhcpcd.conf file by associating static IP settings with a specific SSID (network name).
	~~Edit~~ the dhcpcd.conf file ~~to configure the~~ static IP~~. This file tells your Raspberry Pi to always request the same IP address when connecting to the router~~.

	Open the configuration file ~~using a text editor like nano~~:		Open the DHCP configuration file for editing:

	~~== Step 3: Add Static IP Configuration ==~~		At the end of the file, add the following section, which will apply only when connected to the WiFi network of Router #2:
	~~Scroll to~~ the ~~bottom~~ of the file ~~and~~ add the following ~~lines~~:

	<syntaxhighlight lang="bash">		<syntaxhighlight lang="bash">

	static routers=192.168.2.1		static routers=192.168.2.1
Line 44:		Line 44:
	</syntaxhighlight>		</syntaxhighlight>

	* ~~interface wlan0~~: ~~This specifies~~ the ~~wireless~~ network ~~interface~~.		* ssid "YourExperimentRouterSSID": Replace this with the actual SSID (network name) of Router #2.
	* static ip_address: ~~Set~~ the static IP ~~you want (e.g., 192.168.2.~~2).		* static ip_address: This sets the static IP for the Raspberry Pi when connected to Router #2.
	* static routers: ~~Set this to your router’s~~ IP (~~e.g.,~~ 192.168.2.1).		* static routers: The IP of Router #2 (likely 192.168.2.1).
	* static domain_name_servers: ~~Specify~~ the ~~DNS servers (usually your router's~~ IP ~~and~~ an external DNS like ~~Google's~~ 8.8.8.8).		* static domain_name_servers: The DNS server; it can be the router’s IP or an external DNS (like Google’s 8.8.8.8).

			==3. Save and Exit==

			* Press CTRL + X to exit.
			* Press Y to save changes.
			* Press Enter to confirm.

			==4. Keep DHCP for Other Networks (e.g., Router #1)==

	~~== Step 4: Save and Exit ==~~		When the Pi connects to other networks (such as Router #1 for internet access), it will continue to use DHCP (dynamic IP), because we have not specified static settings for other SSIDs.
	~~After editing~~ the ~~file~~, ~~save the changes:~~

	~~Press CTRL + X to exit~~.		==5. Reboot the Raspberry Pi==

			* Connect to Router #1 (internet network): Verify that the Raspberry Pi receives an IP dynamically via DHCP from Router #1’s IP range (192.168.1.x or similar).

	== ~~Troubleshooting~~ ==		==Important Notes:==
	* ~~If the static IP isn't applied~~, ~~check if the WiFi connection is working~~ and the ~~router's DHCP isn't conflicting with the static IP~~.		* Different Subnets: Routers #1 and #2 should be on different subnets (e.g., 192.168.1.x for Router #1 and 192.168.2.x for Router #2). This ensures no IP conflicts between the two routers.
	* Make sure the ~~static IP (192.168.~~2.~~2) is outside your router’s DHCP range or reserved for~~ static ~~assignment~~.		* SSID: Make sure the SSID of Router #2 is correctly specified in /etc/dhcpcd.conf, as the static IP configuration will only apply when connected to that specific SSID.
	* This ~~should successfully configure your~~ Raspberry Pi ~~with~~ a static IP ~~address~~ connected to ~~your WiFi~~ router.		* This setup ensures that the Raspberry Pi will use a static IP only when connected to the experimental router (Router #2), while using dynamic IP (DHCP) when connected to other networks like Router #1.

To set up a static IP address on your Raspberry Pi so it connects to a WiFi router (e.g., setting it to 192.168.2.2), you will need to modify the Raspberry Pi's network configuration. Below are the steps to achieve this:

== Step 1: Find Your Current Network Information ==
Before configuring the static IP, find out your current network details, such as the gateway and DNS servers, by running the following command:

<syntaxhighlight lang="bash">
ip r
</syntaxhighlight>

This command will output something like this:

<syntaxhighlight lang="bash">
default via 192.168.2.1 dev wlan0
192.168.2.0/24 dev wlan0 proto dhcp src 192.168.2.45 metric 303
</syntaxhighlight>

In this example:

Gateway (router): 192.168.2.1
Network range: 192.168.2.0/24

== Step 2: Modify the DHCP Client Configuration ==
Edit the dhcpcd.conf file to configure the static IP. This file tells your Raspberry Pi to always request the same IP address when connecting to the router.

Open the configuration file using a text editor like nano:

<syntaxhighlight lang="bash">
sudo nano /etc/dhcpcd.conf
</syntaxhighlight>

== Step 3: Add Static IP Configuration ==
Scroll to the bottom of the file and add the following lines:

<syntaxhighlight lang="bash">
interface wlan0
static ip_address=192.168.2.2/24
static routers=192.168.2.1
static domain_name_servers=192.168.2.1 8.8.8.8
</syntaxhighlight>

* interface wlan0: This specifies the wireless network interface.
* static ip_address: Set the static IP you want (e.g., 192.168.2.2).
* static routers: Set this to your router’s IP (e.g., 192.168.2.1).
* static domain_name_servers: Specify the DNS servers (usually your router's IP and an external DNS like Google's 8.8.8.8).

== Step 4: Save and Exit ==
After editing the file, save the changes:

Press CTRL + X to exit.
Press Y to confirm saving the changes.
Press Enter to confirm the file name.

== Step 5: Reboot the Raspberry Pi ==
Reboot your Raspberry Pi to apply the changes:

<syntaxhighlight lang="bash">
sudo reboot
</syntaxhighlight>

== Step 6: Verify the Static IP Address ==
After rebooting, verify that your Raspberry Pi is using the static IP address you set (192.168.2.2) by running:

<syntaxhighlight lang="bash">
ip a
</syntaxhighlight>

Look for the wlan0 interface, and you should see 192.168.2.2 as the IP address.

== Troubleshooting ==
* If the static IP isn't applied, check if the WiFi connection is working and the router's DHCP isn't conflicting with the static IP.
* Make sure the static IP (192.168.2.2) is outside your router’s DHCP range or reserved for static assignment.
* This should successfully configure your Raspberry Pi with a static IP address connected to your WiFi router.
