WiFi Shield Not Communicating

Hi all!

I am having problems with my wifi shield, the ERROR LED is always on whenever I try to run a program. Even the examples are not working, except for the ScanNetworks one.

I thought it was a problem with my router, so I tried connecting the shield with my iPhone (using it as personal Hotspot) but I’m still having the same problem.

Can somebody help?

What is not working?
Is the WiFi shield showing "not present"?
Is it not connecting to the wireless router?
Is it not connecting to a network server?

The ssid and passphrase are case sensitive.

Do you have any "extra" pins on the shield that do not insert into the Arduino? That will be the case if you have a pre-R3 Arduino. I can help you with that. I have a pre-R3 Arduino with a R3 WiFi shield.

all pins in the wifi shield are inserted in the uno

...and how is it not working?
Is the WiFi shield showing "not present"?
Is it not connecting to the wireless router?
Is it not connecting to a network server?

its not connecting to the network

What security are you using on your wireless router? My wifi shield will not connect to my iPhone, but I don't have a tethering plan from my cellphone provider, so I don't know if that has anything to do with it.

Your ssid and passphrase are case sensitive.
