Router wireless mystery

Yesterday our suburb had a 20 min power outage.
I have a DLink DIR 615 Router, with 3 PCs using the Ethernet cable ports,
and, 2 laptops, an iPAD and iPOD using the Wireless access.

Following the power outage the laptops could not access the LAN/Internet,
as, I found out the router had reset itself to Wireless default, so that
the password access/security was different to that "remembered" by the
laptops.
Reset of the security and password solved the problem, however, my query
to any Wireless gurus, is that the iPAD and iPOD could still access the
Internet when the laptops could not.
Is it something to with the LAN ?
PCs are 2 x WinXP and 1 x Win98SE
2 Laptops with Win7 Home
(Or does Apple do things differently?) :-)

The laptops (Win7) could not access the LAN,
The router had reverted to "Auto assign a "key" when I reset it to
"Manually assign a Key" the LAN PCs magically appeared back in the network
details.

Are you sure the wireless default is not an open network not requiring
a password? Or else you once had the iPod on the default setting and
the iPod remembered the default password.

Thanks, yes the router still had the same SSID, but the pass phrase had
changed, so the laptops failed with the message "The access code stored
does not match the required code" (or words to that effect) :-)

If you router has a backup-config utility, use it. You can
restore all your settings in a couple of minutes. Save you a lot of
headaches. Just press the reset button, enter with the default
admin-name/password and restore.
(don't know about the dir615. My Netgear saves it's config to
disk, if asked)

Thanks, Seems like when the power came back on the Cable Modem and Router
would have re-booted together,
(Instead of the recommended "Wait until Cable Modem is active before
powering up the Router."

Never had a problem turning off/on the router only.

Tried that, at the time and they still would not connect to the WiFi LAN

Have done that many times, when leaving the house for a few days, and the
router "retains it's settings.
Seems like the router powering up, before the cable modem had
re-established itself with the ISP may have caused the router to have a
hizzy fit :-)

Re-setting the router to WPA (manual) and re-entering the LAN password
solved the glitch.

Well, the iPAD did, I thought that it had something to do with my LAN, as
the iPAD and iPOD are not able to "see" anything to do with the LAN, just
use the wireless capability of the Router.
The two Netbooks could not connect (using wireless) to the LAN or
Internet.
As I originally stated - a mystery :-)
