WIFI Shield Cant Connect to my home router

I'm Using WPA Security (not enterprise) in fact event when
change my router to "no security" still i can't connect when connecting
to my android personal hotspot it does connecting . can someone advise ?

The ssid and passphrase are both case sensitive. Are you certain they are correct?

What make and model wireless router are you using? TP-Link routers are notorious for rejecting a connection unless the router settings are changed to allow the connection from your Arduino.

Thank you for your reply.

Yes passphrase is case sensetive correct.

I'm using D-LINK A1

And the ssid is also correct? Case sensitive there too.

When you change the security setting on the router from WPA to none, are you changing the call in the Arduino to reflect no security? If the router security is set to none, and you send a passphrase for WPA, the Arduino will not connect.

And the ssid is also correct? Case sensitive there too. [guy] yes

When you change the security setting on the router from WPA to none, are you changing the call in the Arduino to reflect no security?[guy] sure. If the router security is set to none, and you send a passphrase for WPA, the Arduino will not connect.[guy] i'm not adding the passphrase

SOLVED.

From my playing with the router i must have changed accidentally somthing but after
resetting the router completely and starting over it works ... Thank you for your help !

what band you used on your router a-b-n-g ?
and what channel your router works on ?
you changed the band of the router that's what happened :wink:
