Hi  @EdwinDSilva 

if you want to change the card for a dual band card you can use the following one

Hi @Resistencia! Thanks for your prompt response.
Meanwhile, I had been toying with other options. Are these USB Dual-band Adapters any good?

there are models that are very good I use in a laptop one TP-Link and it goes very well.
