D-Link network - strange problem

My networt consist from the following:

Cable modem -> D-Link DI-624
2 laptops on DWL-G650
PC on DWL-G520

The problem is that sometimes (always at the same moment) both of the
laptops lose the connection, the network disappears from the list of
avaliable wireless networks and the only way to fix it is restarting the
router (disconnecting the network adapter, reinstalling it, rebooting the
system - nothing helps)
I was sure that there is something wrong with the router but lataly I
noticed that PC is fine. It doesn't lose the connection, there is no problem
at all with it. And it is not about the signal strenght because the PC is
placed on another floor, laptops are closer to the router.
The PCMCIA adapters have the newest firmeware, that is the original one
because there is no newer, the same about router.
The only thing is that both of the laptops have got static IP, the PC gets
dynamic, but I doubt it could be the problem (??).

Any ideas what is going on and how to manage with it?

Nonetheless, the laptops may experience issues, like interference, that
the PC doesn't experience.

Probably not, but why not use DHCP on all machines?

Since the PC can see signal when the laptops cannot, you probably have
some sort of sporadic interference. Try another location, ideally near
the DI-624, and see if that makes a difference. See the Fast Fixes wiki
below for types of interference and what you can do about them.

Broadcast SSID if not already doing so.
