Hello,

I am using D-Link AG-530 Dual Band Wireless Card (5.8GHz / 2.4GHz).
How to setup the RouerOS so that it can support dual band at same time?
(User can connect with router using 5.8GHz or 2.4GHz)

it is not possible to have one card work on two bands simultaneously (at least none of the current production cards support this). this card can work on either 2.4 or 5 ghz band. i think the documentation of this cards states this clearly enough.
