Np3900/12 and wireless-n network

Hey guys...

My NP3900/12 is not finding the Wireless N network, it's only finding a B-G network.

This is the network configuration:

Attachment 1651

And the NP3900/12 only finds the B-G network, not the N network:

Attachment 1652

According to specs this equipment has 802.11n support, why is not finding the N network? ANY ADVICE TO FIX THIS?

EDITED: AND NOW IS FREEZING WITHOUT ANY REASON!! THINKING IN RETURN THIS EQUIPMENT!

Hi Diego, the NP3900 has a 2.4 GHz 802.11N Wifi Adapter. So You can connect it to the N Wireless Lan only at 2.4Ghz and not at 5 Ghz. Change Your AP configuration Wireless Network Mode for 2.4Ghz and enable N too.
