Getting IP but cannot connect

Hello,

First of all, this is the output I got in my serial monitor window:

Attempting to connect to SSID: CMN
SSID: CMN
IP Address: 192.168.2.6
signal strength (RSSI):-68 dBm

But when I look on my firewall/dhcp server, I dont see this IP there… not sure what I am doing wrong. Below is the sketch for the same:

/*
WiFi Web Server

A simple web server that shows the value of the analog input pins.
using a WiFi shield.

This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.

Circuit:

  • WiFi shield attached
  • Analog inputs attached to pins A0 through A5 (optional)

Some dhcp server is issuing this address.

IP Address: 192.168.2.6

Are you certain you are looking in the right place on your router? Mine shows up under "ip dhcp-server lease".

Hello,

Yes. I am certain. I looked it up everywhere. Basically this sketch is supposed to create a simple web server that I can browse to but when I do, I see "Page not found"

If the response is "Page not found" instead of "unable to connect to the server", you have a problem. That is a response after the client connects to the server successfully, but the server was unable to find the requested file.

are you using http://192.168.2.6 in your web browser address bar?

Yes. that is exactly what I am typing. I even added some more parameters to my Serial Monitor output:

Attempting to connect to SSID: CMN
SSID: CMN
IP Address: 192.168.2.6
Gateway: 192.168.2.1
Subnet Mask: 255.255.255.0
signal strength (RSSI):-70 dBm

So the gateway and Subnet are correct. It is getting the correct info.

The Arduino code you are using doesn't send a "Page not found" error. That is sent by the server AFTER the connection is established and the client sends a page request. ??
