TCP/IP not working on one of two computers -> 1 router

Okay so my desktop with a refurb D-Link DWL-G510 all of a sudden won't talk
to the Linksys WCG200 wireless router we have here. This is the weird
thing. The WCG200 has always had the problem of random 10-minute interval
dropouts, but yesterday, the desktop completely bit the dust concerning
connectivity.

This is the weird thing. The laptop I'm using has a Ralink 802.11g MiniPCI
built into it, and it gets its IP/DHCP/Subnet through the Linksys router all
resolved nice and dandy to something like 66.250.204.x but the desktop keeps
resorting to the local 192.168.0.15. Aren't wireless routers by default
supposed to reserve the pool of 192.168 addresses for its internal WLAN and
use one internet IP for the other side?

There are up to 5 of us using the internet at the same time, and with no
real problems except for my desktop. The thing is, the 'connected clients'
listing in the router setup shows ONLY the WLAN-only desktop, not the
WAN-connected clients. Why would this be?

When the connection died, the desktop simply stopped working right all of a
sudden... I made no network changes of any kind. I've selected DHCP to try
to manually assign, then revert to automatically select address... both of
them are no go.

Why would a router assign one network adapter an internal address and keep
it on the internal network, while letting everyone else access the outside?
Is there a TCP/IP setting that could "let it out" like everyone else?

I had a similar with two HP refubs (same model). One of them would never
work with the PCI D-Link wireless to either a US Robotics or 2Wire
router. Worked ok from a D-Link USB wireless though for like 4 months.
Then it quit.

I swapped drives and cards from the same HP model and then that one quit
working too. Now neither one would work with any router. Although they
weren't getting an IP address. All other computers were working fine.
And the 2 HP computers only worked from dialup and nothing else. Did a
dualboot install with a fresh copy of Windows and still a no go. Tried 2
D-Link PCI wireless, 2 D-Link USB wireless (refubs), and 1 USB Belkin
wireless. And even wired directly to the router.

Months later I bought some 2Wire HomePNA. I just tried one of them and
that works great on one of the HP computers. The other one is still in
pieces. And I have no idea why HomePNA is working while other methods
are not. I am convinced it isn't the software, but something in the
hardware.
