Dlink-524 Wireless Router Won't Hold Internet Connection

I asked this in another group on November 9, but got no replies, so I
thought I'd try here.

I've got a Dlink-524 router, connected to a Comcast modem. I
somethimes
connect my Dell laptop wirelessly to the router, and sometimes I
connect
it with an ethernet cable to a LAN port. I always have a desktop
connected to one of the router's LAN ports. Wireless and LAN
connections
have been working fine for almost a year.

(It's an Inspiron 6400, with an Intel 3945 NIC. I normally run the
Intel wireless connectoid, but the Microsoft one works, too. I've
tried both to solve this problem, but no luck.)

This relates to laptop.
In the last few weeks, I've been able to maintain the laptop's
wireless
connection, and the wired connection, to the router, as shown by the
icons in the system tray, but when I try to get on the internet, my IE
6
browser opens, but I get nowhere. I first tried powercycling the
modem,
the laptop and the router (in the proper order). This worked, but
only
for a minute or so, as I'd loose my internet rather quickly, both over
the wired and the wireless connections, even though those connections
still showed working in the system tray.

While all this is happening, the desktop's wired connection is fine,
and
I can get on the internet.

I'm beginning to wonder if the router is crapping out, but I don't
know
why the desktop's wired connection is fine and gets me on the
internet,
and the laptop's wired and wireless connection show fine, but I can't
get
on the internet.

Anyone know why I can't connect to the internet even though the system
tray icons show that I'm connected to either/both the wired and
wireless
connection?

November 28 update:
When this first began happening on November 19, I replaced the failing
(?) router with another Dlink-524 wireless router than I had around
the house, and that had been previously set up on my network for this
laptop. The laptop instantly found this router, connected, and has
kept the wireless and internet connection since. But, I'm still
wondering about the original router. I don't mind just chucking it
(routers are cheap enough), but I don't understand what was going on.

Thanks.

wireless security protocol incompatibility.
i've had that before.

when testing the wireless, disconnect the wired cable.
also, u always use microsoft wireless to control, not intel.
its faster.
disable the other intel products. you cant keep all that stuff running.
then reauthenticate yoruself to the wireless.
perhaps your wireless security settings changed ...
check them out, reset them if nec.
