MC40 Wifi Issues



I'm developing an app on the MC-40HC (HealthCare Edition). But when I try to connect to a Wireless Network it connects, but I can't load any data/webpages.  Any ideas?


Extra information:

- I turned off 802.11d and set my country manually.

- He got an IP-address via DHCP and it's in range

- I can't ping to the device

- Gateway is correct


with kind regards,
