PDA access on MN-700/MN-710

I have an MN-700 wireless router that I cannot get WIFI PDAs to access
through. The firmware has been upgraded.

I have two laptops running XP that work just fine, but neither my HP nor my
Palm can get connected.

They see the network but will not connect with the password and security
settings input.

I have looked at the choices of encription available on the router and on
the PDAs and they do not seem to be compatible. The number of bits for WEP
is different. They do not share any with the same number of bits of
encription. I've also tried the WAP-PSK settings, but they don't work with
the PDAs although they work fine with the laptops.

What can I do to get these hooked up?

Thanks a million.
