Hi All,
I am totaly new to arduino and programming. I want some information on the wifi setup. I created a wireless lan network that all my devices can log onto. My question, can I still control and receive information from the arduino via my wifi network without this network having access to the internet?
I tried the example of the "simplewebserverWifi" from the IDE but it does not seem to work. The wifi shield logs on but when I write from a PC that is also connected to the network it comes back with a message that the web site can not be accessed due to no internet connectivity.
Please help

That normally means the PC thinks the wifi shield is not on a local network and can't reach the gateway.
What network settings does your PC have? What network settings does your wifi shield have?
Thanks for the reply,
How would I be able to check the settings and for what configuration should I look? Am I correct in saying that I do not need an internet connection for my network to work.
Thanks
You shouldn't. What IP does the wifi shield show?
I don't know what OS you are using, but you can open a terminal and type ifconfig for Linux or ipconfig for Windows. That should display your network settings for the PC.
My IP on the shield shows 192.168.1.149
My modem's IP is 192.168.1.124

The modem or the PC? If that is correct for the PC, then it shouldn't need an internet connection to establish that localnet connection. The only problem I can see is if the PC tried a nslookup on the IP, and couldn't connect to the dns server. It shouldn't need to resolve an IP, but who knows.
Can you ping the Arduino's IP from the PC?
Hi Surfer,
So last night I called my brother which has a more experience with these types of things.Firstly, I must apologize, it is a rooter and not a modem. This is what we did. With the shield connected and the PC connected wirelessly, I could ping the rooter from the pc but not the shield. I then used a network cable and connected the rooter to the pc via the cable. I could then ping the shield and the pc picked it up but the arduino still did not respond to the commands I tiped into the browser window namely http://192.168.1.149/H
Hope this will get us a little closer to the problem
What make/model router do you have? Some routers use different IP subnets on the wifi and ethernet localnets. Maybe your router is one of those.

Then you either do not have server software running on the Arduino, or you have not performed the firmware upgrade.
