I am trying to use FST on this network.
+---------------+ +---------------+
| AP1(11g) | | AP2(11a) |
| 192.168.100.1 | | 192.168.200.1 |
+--------+------+ +-------+-------+
| |
|(11g) |(11a)
| |
+--------+------+ +-------+-------+
| STA1(11g) | | STA2(11a) |
| 192.168.100.2 | | 192.168.200.2 |
+---------------+ +---------------+
(initiator=STA,old iface=STA1, new iface=STA2)
It looks succeeded because the state in log is
TRANSITION_DONE -> TRANSITION_CONFIRMED -> INITIAL.
After that, I expects the stream from STA1 to AP1 go through 11a path.
But ping from STA1 to AP1 go through 11g path.
ping from STA2 to AP2 go through 11a path also.
Is my expectation right ?
STA log
