About WPS on two interfaces of dual band

[Anand Moon]

Hi Annapurna,

Many be you need to generate different UID's for different hostapd configuration.

WPS needs the Universally Unique IDentifier (UUID; see RFC 4122) for
the device. This is configured in the runtime configuration for
wpa_supplicant (if not set, UUID will be generated based on local MAC
address):

# example UUID for WPS
uuid=12345678-9abc-def0-1234-56789abcdef0

Please read the hostapd.conf file example for more details.
