I have tried to set up a peer-to-peer WLAN using a Belkin ADSL Modem with
Wireless g Router connected via an ethernet port to my desktop and a Belkin
Wireless g Notebook Network card in my laptop.  I do not have broadband as
yet and use dial-up access from my desktop for internet access.  Both
machines are running XP Home.

I did succeed in getting this working and can access files in the shared
drives on each computer from the other conmputer.  I can also access the
internet OK from the laptop using the desktop dial-up connection over the
WLAN.

I then decided to set security on.

The manual states I should enter 192.168.2.1 in an Internet Explorer address
bar to access the router settings, which I did originally to set it up and
was successful.  Now, however, when I do this, I get a Page Not Found.  I
have tried various things unsuccessfully.

If I ping the IP, I either get a "Destination host is unreachable" if I have
not established an internet connection or a "Request timed out" message if I
have dialled up and connected to the internet.  I have tried resetting the
router to the factory defaults, but still get the same results.

The manual says to clear "Automatically detect Settings", "Use Automatic
configuration script" and "Use a proxy server" in Internet options for the
LAN Settings.  If I do this, IE just closes itself and when I reopen it, any
changes I made have been lost.

Can anybody help me to get access to the router settings so that I can get
everything working again and switch security on?
