We have had massive problems with our protocol analyzer gear the last days. Tuesday - yes, when the sun storm arrived - we witnessed that alot of frames did not show up in the protocol analyzer. Especially larger dataframes where either gone or corrupted. Small frames, like beacons,voice data or Acks did not suffer that much. Although we knew that frames where being sent (pings, streaming video), they did not show up.
We have tested with different pieces of hardware to be sure: Wireshark with Airpcap NX Airmagnet analyzer with Proxim 8494 and C1060 Ethereal with PRISM Duette
Testing was performed at different locations the last days, all with the same result. Only the 25th in the evening DSSS showed up properly, and, although it is getting better we still miss frames with OFDM.We also saw an increase in retries, but luckily not so bad as you would have assumed from the sniffer traces.
I wonder if someone has had the same experience, we can still reproduce it. Just start a ping and check if both ToDS and FromDS show up in the sniffer. We are located in the Netherlands and have tested at different locations.
