network card in Sony laptop and router 'dual band' capability

[D_a_f_f_D]

I wonder if anybody can assist please?  I'm afraid I'm new to this ... so pls bear with me.  The network card in the Sony laptop VPC-F23C is Wireless LAN(bgn). I am looking to upgrade my router to an 'n' type in the future & was looking at a 'dual band N' router. Is the network card that's in this laptop able to use the 'dual band' part of the router or will it just use the 'N'?  I'm trying to find out more detailed info about which particular network card is in this laptop - but not having much luck - all I know is that it's 'Wireless LAN (b/g/n)'.  Thank ye kindly.

Hi D_a_f_f_D,

Your wireless card supports both 2.4 and 5 GHz so the answer is yes it will be able to use the 'dual band' part of the router. The question really is do you need a dual band router?

Have a look at the following link:
