I have an Inspiron 15 7537 and the wireless card seems to be malfunctioning, so I want to replace it.

It's a Wireless-N 7260 
802.11n for 2.4 GHz only
Ad Hoc 802.11b/g

this is the specs i've found:

this card is discontinued

Can I replace it with a dual band? or what are the suggestions to replace it?
