I forgot to ask as it didn't occur to me before. Are any of your SSIDs

I have done some more tests with the Proxim AP4000, but I still cannot
see a problem in the protocol. I have put an ammeter inline between the
N810 battery and connectors so I can see the current consumption in real
time - it is pretty impressive that it can draw virtually no current at
all (<

Well, I got one. The power consumption seems normal (i.e. PS mode seems
to be working).

Andrew,
after thinking about Kalle's explanation of PSM, and as the owner of a
UTStarcom Windows Mobile handset (Verizon Wireless XV6700) that supports
both EVDO and 802.11b, I have to conclude that, The UTS XV6700 does not
do a satisfactory job with respect to PSM.
My conclusion here is based
