Are you using a routing protocol?
In other case the routing table is incorrect and the node doesn’t know the appropriate interface that it needs to use.

Asunto: [Omnetpp-l] Inet multiradio coexistence
I'm really noob with INET and I'm trying to setted up a simple ad-hoc network (AODV routing) where all nodes use 802.11g(mixed) (default setting, 2.4 GHz) on wlan[0]. Only nodeA and nodeB have a double radio with 802.11a (5GHz) on wlan[1].
[...
UDP APP, A send B UDPData
AODV Routing
...]
# number of radios per host A-B
*.host*.numRadios = 2
# number of radios per mhost
*.mhost*.numRadios = 1
# Ieee 802.11g NIC settings for all host
*.radioMediumType1 = "Ieee80211ScalarRadioMedium"
*.*host*.wlan[0].radio.radioMediumModule = "radioMedium"
*.*host*.wlan[0].typename = "Ieee80211Nic"
*.*host*.wlan[0].mgmtType = "Ieee80211MgmtAdhoc"
*.*host*.wlan[0].opMode = "g(mixed)"
*.*host*.wlan[0].radio.bandName = "2.4 GHz"
*.*host*.wlan[0].radio.carrierFrequency = 2.412GHz
*.*host*.wlan[0].bitrate = default
# Ieee 802.11a NIC settings for A-B
*.radioMediumType1 = "Ieee80211ScalarRadioMedium"
*.mhost*.wlan[1].radio.radioMediumModule = "radioMedium"
*.mhost*.wlan[1].typename = "Ieee80211Nic"
*.mhost*.wlan[1].mgmtType = "Ieee80211MgmtAdhoc"
*.mhost*.wlan[1].opMode = "a"
*.mhost*.wlan[1].radio.bandName = "5 GHz"
*.mhost*.wlan[1].radio.carrierFrequency = 5GHz
*.mhost*.wlan[1].bitrate = 54Mbps
Unfortunately nodeA and nodeB are not able to exchange UDP packet through wlan[1], as I expect.
WHY? I need you help.
Thanks in advanced.

You should check the protocol configuration, they usually has a parameter that sets the interfaces that the protocol must use to discover the routes, it is possible that the default configuration only sets one interface, in this case the protocol only discover the nodes using this interface only
