Problem with D-Link DI-524, please help!!!

Hi everyone,

I have tried almost everything but my D-Link DI-524 Router still
doesn't work. However, I am new into these wireless gadgets, so I
thought I should get some inputs from the pros before giving it back to
the store.

Let me explain to you what I wanted. I have a laptop with XP SP2, and
all I wanted was to go surfing wireless around the house, nothing more.
No networks, no multiple connections, not the fancy stuff. My cable
modem is a Motorola Surfboard SB5100E, which has been working just
fine. My D-Link DI-524 (Version B.2, as if I didn't have enough
problems) came bundled with the Wireless USB-Adapter DWL-G122. As
ethernet card in my laptop I have a D-Link DFE-690TXD.

I installed the Router just as the D-Link QIG says so:
- turn everything off
- turn on the modem,
- connect the modem to the router,
- after the signal is received turn on the router,
- connect the router to the computer's ethernet card, turn the
computer on,
- run the installation program; I clone the MAC address of the ethernet
card (Home menu, WAN), keep DHCP enabled (Home menu, DHCP) and then I
renew the DHCP on the status menu, device info.
- run the wireless installation, USB is recognized and gets signal,
everything works fine the first time. I can surf, I can connect to MSN
Messenger, the basic stuff. I turn the computer off and call it a day.

Next morning, I restart the computer. What I mean by this is, I turn
everything off the night before, then everything on the next day. A
friend told me that I was not supposed to cut the electricity off the
router, as the configuration may get lost. Is that so??

Anyway, when I start the computer, the connections are recognized, I
have a wireless signal and so on. Funny enough (although not that
funny after three days trying to configure the router), when I go
surfing nothing works. Also, I try to connect to MSN Messenger and it
says that it cannot connect. I ran the MSN utility and it says that it
has problems with the DNS.

I go to the router menu (192.168.0.1) and I see that the DHCP
connection is lost. I renew it, and then everything goes back to
normal. Do you guys have any clue why is this happening. Is my friend
right, am I not supposed to turn the router off by no means??

I went to the router menu (192.168.0.1) and disabled the DHCP-Server.
The WAN connection worked beautifully. But I lost the DNS on the
wireless. I mean, I am on the verge of giving up. I need your help,
please guys!!!

Anyway, there was something stranger. I was having this problem the
other day, and I started emule. Well, when I connected emule,
everything worked afterwards. Any inputs on this one??

Thanks for your help in advance. Have a good day.
