Some users can't connect but administrator fine

I have a XP Home SP2 box (ECS MB, Pentium D 3.2, 1MB RAM, 300MB HD) with
D-Link 510 wireless card. The Administrator account connects fine but I'm
kind of pushy about not using it unless absolutely necessary. The limited
users, however, are connected on login, then are immediately disconnected and
reconnect. One of the users usually does reconnect (sometimes takes a minute
or more), but the other two either never do or get the dreaded "limited
connectivity" message.

Another computer in the house (Pentium 3, 512M, Asus MB, XP Home SP2, older
D-Link 510) usually connects OK for all limited users and Admin though
sometimes slowly (it also does the disconnect-reconnect routine). Work laptop
(IBM X60, XP Pro SP2) connects fine. Home office computer (XP Pro SP2) is
wired to the router and of course connects fine. XP Home boxes are
clean-installed XP Home upgrades from Win98SE. XP Pro boxes are OEM IBM and
Gateway.

Router/Access Point is a Linksys WRT54G set up for WPA-PSK and not
broadcasting. Network is used only for accessing Internet - no file/printer
sharing (it's turned off on all the computers).

At one point I thought it was signal strength (typically got "low" or "very
low") - improved with an external antenna but didn't change the connection
issue.

Any ideas what I should look for to fix this so all the users can connect?
Thanks.

Enable broadcast. See if that makes a difference.
