Also, fwiw, he wont get a node type unless he is getting DHCP from a windows
server that is configured to assign a netbios node type, which typically
involves WINS servers.

It is likely that he has to tell his browser to go via a proxy server of
some kind. I am sure there are some instructions laying around that explain
how to configure your system before you can use thier service, along with
thier acceptable usage policy.

Where is that button or link located? It's not on the above-mentioned
page. I asked a clerk at the downtown library today if there was
anything I needed to set online beforehand, but she didn't know of
any.

I don't understand what the above settings are doing for me. The
directions I've read don't require me to modify the registry settings.

I can't find any network bridge setting.

As mentioned above, I have already installed XP2.

I've now visited 4 libraries, including the main one downtown.

Thanks for your reply. Sorry I couldn't reply earlier.

Thanks for your reply. The configurations specifically required the
user to disable all proxies.

The instructions simply say that I am to turn off any proxy service.

After comparing the library's ipconfig /all results with that at my
brother's house, I noticed that the DHCP at the library = 1.1.1.1
while that at my brother's house is set to the value of the Default
Gateway IP. Is there anything unusual about that?

DHCP Enabled = Yes
Autoconfiguration Enabled = Yes
IP Address = 172.30.2.123
Subnet Mask = 255.255.255.0
Default Gateway = 172.30.2.1
DHCP Server = 1.1.1.1

I finally got online by launching the gateway IP into my browser
window. I got a blank page but noticed that the page title contained
the word "redirect," so I looked at the View/Source and noticed that
it redirected to http//1.1.1.1/login.html?<gateway address>.

I entered only http://1.1.1.1/login.html into the window and got a
login page, which eventually allowed me to surf the net. A previous
poster gave a URL for the login page but I got a "page not found"
error from that link when launching it from my newsreader. When I went
to the library's FAQ on another computer I found a login page link,
but it had been inactivated. I also noted that none of the library's
WiFi brochure info indicated that a login page was necessary before
surfing.

Thanks again to all for responding. I really appreciate all the
problem-solving ideas.

Howdy,

There are very few people who know less about this than I,
but...

Just yesterday, I had virtually the same problem on my
office net.

The solution was in modifying the D-Link (my PCMCIA wireless
card's) configuration with regard "Authentication Mode."

I don't have that system at hand right now, but IIRC, the
setting I needed was "Open" Authentication. (That is not to
suggest that your required setting will be the same, but as
I understand it, the system Authentication Mode and the
Wireless net's must match.)

Once I stumbled on that, all was golden...

Good luck with it,

Kenneth
