Linksys/Dell SRX400 problem with WPA-PSK/TKIP

["Robert G. Brown" <rgb phy duke edu>]

Hi, I'm trying to establish WPA-PSK connections to a linksys router.  At
home I currently have a fancy new netgear WPN824v2 rangemax WAP/router
and WPA-PSK/TKIP to it seems to work just fine with a preshared key.  At
a medical practice I'm trying to help set up, the Linksys routers "have"
to be set up WPA-PSK/TKIP in order for doc PDAs to be able to wirelessly
connect and use certain applications.  I discovered empirically when
setting them up originally that they'd work within NM 0.6.4 with the WAP
set up to use WPA-PSK/AES and a preshared key, but when the WAP is
switched to TKIP with the same preshared key, it refuses to connect.  In
terms of stages, the little lower ball doesn't turn green and the log
shows no connection or advances to where DHCP can happen.  For example:

...

where at no time does it get a connection (and it periodically complains
about being disconnected).  Doesn't look quite like it does when it
successfully connects.

Has anyone seen this before?  Is there a workaround or am I doing
something stupid?  It's really inconvenient to have to hook into the
network directly, especially since the core network is a total mess (no
DHCP server at all, for example, so all eth0 connections have to be done
the hard way).  Before, with WPA-PSK/EAS I was able to go all over the
building from a single WAP.  Sigh.
