how far away are you ? from the router? (11b hates noise)
IPAQ are obsolete
why not ask at HP, since its there old device.
ask here.

i cant see your router
its name, or its model number nor the wifi pages inside.
obviously wpa is not working in the IPAQ or is not compatible.
there are sub modes of WPA, and many old devices like this IPAQ do not support, back long ago that was COMMON.
here is its complance spec.
Compliant to 802.1b (EAP-TLS, PEAP)
WPa
one poster said
HP-IPAQ-rx3115 is only 802.11
b 11mbit (ONLY) so does the book
that means do NOT TURN OFF
11b in the router !
hp seems to have deleted all support, only asking in there forum works now, zero files books.
13 years old this, is.
i had to google for you, for the book. why not yOU?

so your router has broadcast SSID name.
like ROVER
and a password,?
then set to WPA, (try all submodes in the router)???????
page 8-4 covers manual settings if wifi.
my router a top brand, DIR655
has , mixed mode set, then
WPA and WAP2 both on....
then wpa-personal mode
then TKIP and AES both (my guess is you have this wrong)
see how that allows older hardware work on a modern router?
make sure AUTO channels is on, for up to 14 possible.
i read your manual and it clearly fails to mention sub modes
that tells me 2 thing,s its an old relic, and 2, has no submode choices only fixed mode and NOT STATED what it is,
bad that.
most old laptops do this same bad act, most.
seen many, do that, infact some only do WPA and only 1 submode
or only old insecure WEP. only
lived that era, dont miss it at all. why use this old thing at all>?
as street value of what $5 pack of cigs , as we used to say?
11b is 1999 spec (OLD) 18 years old now.
run 1 band, e same
2.4GHz band
802.11b devices suffer interference from other products operating in the 2.4 GHz band. Devices operating in the 2.4 GHz range include:
microwave ovens,
Bluetooth devices, baby monitors and cordless telephones. Interference issues and user density problems within the 2.4 GHz band have become a major concern and frustration for users.
