FYI You have two 100mW cards and one 180mW card. The 180mW card does
draw 20mA more then the 100mW. This should not be causing a problem but
as you know the AP-1000 is picky about power.  Also there is a new
firmware that might help on the website.

Subject: MIB strings from Demarc PRISM 2.5 cards 


I'm having a problem with hang on reboot on my AP-1000 running KN 4.02
with two of Tony's 100mW PRISM 2.5 card in it.  The hang was in the last
light, or the .11/3 or "B" interface. It has been running very smoothly
for the last month with these same cards in it, but the problem is
eluding an easy answer.  The only change was that 5 days ago, the .11/3
or "B" interface, which is being used as a backhaul, recently got a
100mW PRISM card on the other side of the link.  Interestingly enough,
the signal levels reported back were different by 5 dB, even though the
antennas and radios were
indentical on both sides.   I swapped the two radio cards in the the
AP-1000, and walla! signal levels in the backhaul went to indentical
(-75dB), as it should be.  So, something strange about the .11/3 radio.

In probing around a bit with a MIB browser in the AP-1000, I noticed
that the strings that came back from the two, visually identical cards
slotted in the AP-1000 revealed some differences.

.11/3 was "IEEE 802.11 Wireless LAN/PC Car IEEE 802.11 Wireless LAN/PC
Car STA Var=6 Ver=1.03; 4;"

but that from .11/2 was:

"IEEE 802.11 Wireless LAN/PC Car STA Var=6 Ver=1.03; 4;"

Seems that the /3 card has some scrambled info in it's description.

Note that the id string from the other side of the backhaul, which is a
visually identical 100mW PRISM 2.5 card is: "IEEE 802.11 Wireless LAN/PC
Car STA Var=6 Ver=1.03; 4;"

Which seems to match that of the, what is beginning to look like, known
good, radio in the AP-1000.

Any possiblity that this could be the source of the hanging?  Will
reflashing the /3 radio card take care of this situation?
