Dear Mikrotik Forum,
I am confused about Nstreme, so I would like you answer my doubt.
What the difference is when I set my wireless card as:
1. "interface wireless set wireless-protocol=nstreme 0"
2. "interface wireless nstreme set enable-nstreme=yes 0"
Both command lines do the same?, Should I set my wireless card with both command lines?
Thanks a lot.

Please, I need some help. Thanks.

the first one force to connect only with a device with wireless-protocol=nstreme or wireless-protocol=any
the second one enable the nstream in the wlan.

these are two separate options

if you want to use nstream, you need to set enable-nstreme=yes, either in station and in the ap
then if station have wireless-protocol=any and the AP have wireless-protocol=nstreme, the connection is made using nstream

Thanks. I believe I understood.
