Epocrates server through a Linksys BEFW11S4

Am trying to get my PDA to sync with one of the boxes we have on a wireless
connection at home.

I keep getting an error something to the manner of 5459, which Palm tells me
is related to the networking and not a problem with the PDA, and ePocrates
pretty much reiterates the same thing. The main box connected to the cable
has enough crap sitting around it without another hot sync cradle.
I've disabled the timeout feature on the PDA, but still no joy.

Don't think it's of any importance, the PDA software is v3.53, and desktop
is 4.01.

Thanks
