32 ESSIDs (16 per radio 802.11a and 16 per radio 802.11g) are created at the enterprise wireless controller, there is a problem in capturing all the 32 ESSIDs using wireless sniffer.

Neither tethereal or iwlist can do that.

I had tried these:

tethereal without filter with 10000 packets:

# tethereal -i ath0 -c 10000 -w /tmp/sniff.capture.c10000

# tethereal -V -r /tmp/sniff.capture.c10000 > /tmp/sniff.capture.c10000.txt

/tmp/sniff.capture.c10000.txt does not have all 32 ESSIDs.

“iwlist ath0 scan” get less than 32 ESSIDs at a time.

# iwconfig ath0 mode Managed

# iwlist ath0 scan


How to fix this problem?
