+EthernetLWIP (Wired Ethernet) Support
+=====================================
+
+Wired Ethernet interfaces are supported for all the internal networking
+libraries (``WiFiClient``, ``WiFiClientSecure``, ``WiFiServer``,
+``WiFiServerSecure``, ``WiFiUDP``, ``WebServer``, ``Updater``,
+``HTTPClient``, etc.).
+
+Using these wired interfaces is very similar to using the Pico-W WiFi
+so most examples in the core only require minor modifications to use
+a wired interface.
+
+Supported Wired Ethernet Modules
+--------------------------------
+
+* Wiznet W5100(s)
+
+* Wiznet W5500
+
+* ENC28J60
+
+
+Enabling Wired Ethernet
+-----------------------
+
+Simply replace the WiFi include at the top with:
+
+.. code:: cpp
+
+    #include <W5500lwIP.h> // Or W5100lwIP.h or ENC28J60.h
+    
+
+And add a global Ethernet object of the same type:
+
+.. code:: cpp
+
+    Wiznet5500lwIP eth(1); // Parameter is the Chip Select pin
+
+In your ``setup()`` you may adjust the SPI pins you're using to
+match your hardware (be sure they are legal for the RP2040!), or
+skip this if you're using the default ones:
+
+.. code:: cpp
+
+    void setup() {
+        SPI.setRX(0);
+        SPI.setCS(1);
+        SPI.setSCK(2);
+        SPI.setTX(3);
+        ....
+    }
+
+And finally replace the ``WiFi.begin()`` and ``WiFi.connected()``
+calls with ``eth.begin()`` and ``eth.connected()``:
+
+.. code:: cpp
+
+    void setup() {
+        ....
+        // WiFi.begin(SSID, PASS)
+        eth.begin();
+        
+        //while (!WiFi.connected()) {
+        while (!eth.connected()) {
+            Serial.print(".");
+        }
+
+        Serial.print("IP address: ");
+        //Serial.println(WiFi.localIP());
+        Serial.println(eth.localIP());
+
+        ....
+    }
+
+Adjusting LWIP Polling
+----------------------
+
+LWIP operates in a polling mode for the wired Ethernet devices.  By default it will run
+every 20ms, meaning that on average it will take half that time (10ms) before a packet
+received in the Ethernet module is received and operated upon by the Pico.  This gives
+very low CPU utilization but in some cases this latency can affect performance.
+
+Adding a call to ``lwipPollingPeriod(XXX)`` (where ``XXXX`` is the polling period in
+milliseconds) can adjust this setting on the fly.  Note that if you set it too low, the
+Pico may not have enough time to service the Ethernet port before the timer fires again,
+leading to a lock up and hang.
+
+
+Adjusting SPI Speed
+-------------------
+
+By default a 4MHz clock will be used to clock data into and out of the Ethernet module.
+Depending on the module and your wiring, a higher SPI clock may increase performance (but
+too high of a clock will cause communications problems or hangs).
+
+This value may be adjusted using the ``eth.setSPISpeed(hz)`` call **before** starting the
+device.  (You may also use custom ``SPISettings`` instead via ``eth.setSPISettings(spis)```)
+
+For example, to set the W5500 to use a 30MHZ clock:
+
+.. code:: cpp
+
+    #include <W5500lwIP.h>
+    Wiznet5500lwIP eth(1);
+
+    void setup() {
+        eth.setSPISpeed(30000000);
+        lwipPollingPeriod(3);
+        ...
+        eth.begin();
+        ...
+    }
+
+Using the WIZnet W5100S-EVB-Pico
+--------------------------------
+
+You can use the onboard Ethernet chip with these drivers by utilizing the following options:
+
+.. code:: cpp
+
+    #include <W5100lwIP.h>
+    Wiznet5100lwIP eth(17);  // Note chip select is **17**
+
+    void setup() {
+        // Set SPI to the onboard Wiznet chip
+        SPI.setRX(16);
+        SPI.setCS(17);
+        SPI.setSCK(18);
+        SPI.setTX(19);
+        ...
+        eth.begin();
+        ...
+    }
+
+Example Code
+------------
+
+The following examples allow switching between WiFi and Ethernet:
+
+* ``WebServer/AdvancedWebServer``
+
+* ``HTTPClient/BasicHTTPSClient``
+
+Caveats
+-------
+
+The same restrictions for ``WiFi`` apply to these Ethernet classes, namely:
+
+* Only core 0 may run any networking related code.
+
+* In FreeRTOS, only the ``setup`` and ``loop`` task can call networking libraries, not any tasks.
