WinXP, SP2 IE 6Ken,
I am having difficulty getting online in a wireless hotspot where others
do not seem to have a problem. I have no problem at other hotspots.
I am assigned an IP address but I am unable to browse online with IE6
(or Firefox, for that matter). I have set my security and privacy
settings to medium and I have even tried going bare without a firewall.
How do I begin to troubleshoot this issue? If it were not for the fact
that the next closest hotspot is 1/2 hour away, I wouldn't bother.
Thanks

If you have connectivity to the hotspot (and verifying that is best left to the
modern equivalent of Job), you have 2 possible problems.
# DNS.
# MTU.
Diagnose the problem first.

# From a command window:
1. Ping www.yahoo.com.
2. Ping 66.94.230.33.
3. Report success / exact text of error messages.
# From your browser:
1. Browse www.yahoo.com.
2. Browse 66.94.230.33.
3. Report success / exact text of error messages.
If you can ping and browse by IP address, but not by name, then we will have to
check DNS. If you have a personal firewall on your computer, then you'll most
likely have to set the firewall to trust the DNS server.
If the problem is NOT DNS, then check for the MTU issue. Read my article, and
the linked articles.

An unbalanced pair to say the least.
Are you sure that this is the connection that the others are accessing? Looks
wonky to me. Maybe a man-in-the-middle attack?
And you with no firewall connecting? Can you say "malware host in the making"?
What is this hotspot? The one 1/2 hour away? Why do you need hotspots?
I was the only person in the restaurant this AM. I am a radiologist in
the midst of relocating. I am 2 1/2 hours from home (Fresno) in a
beach house in Avila Beachh, CA, on loan from a friend for the next
month while my wife and I find a home. This cafe/market serves a
private development and is 5 minutes from the beach house. My office in
San Luis Obispo is 20-30 minutes away, so it would be convenient to just
stop in at the market on weekends to pick up email, etc., without
having to make the drive to San Luis Obispo.
I have never seen more than 2-3 people using their laptops at one time
inthe market. I was the only one there this AM. Yesterday my IP
address was 192.168.1.103.
Charter communications serves this area (San Luis Obispo, Santa Barbara).
For this AM, I uninstalled Zone Alarm. I share your concerns about
malware, etc. I wanted to make sure that there was nothing between me
and the router.
Any suggestions?
Thanks
Ken
Ken,
OK, good background there. So we'll start from assumptions:
# You are connecting to the hotspot.
# This is a valid hotspot, and there is nothing intentionally malicious in
progress.
Your ping Yahoo, by name and by IP address, suggests lack of connectivity from
the hotspot to the Internet. But you do have working connectivity when using
another hotspot?
This doesn't say much for the hotspot though. It starts to sound like a
candidate for malware, at least inadvertently spread.
Is it possible, at all, that you are connecting to the router, but it wants you
to authenticate before allowing you further? Routers that don't do port based
authentication could get you to this point, and no farther.

Try the same 4 way test on another website, one which you actually need access
to. Resolve IP addresses using these two web sites (using IP addresses because
you would not have DNS to test from):
http://216.92.207.177/toolbox
http://69.2.200.183/
Given no more clues, I'll eventually suspect LSP / Winsock corruption. That's a
painful thing to diagnose, though.

Be patient here, and keep feeding me ideas.
has any grudges against their clients--you are correct.
WRT other hotspots, I occasionally use the ones at Starbucks without any
problem. WRT Avila Market, I am told that I am one of 2-3 people who
have difficulty but that many others have none. One day I spent a half
hour with a bright fellow who works there and he was surprised that I
was unable to connect. We tried a direct connection to circumvent any
problems with wireless but that did not change anything. There is a
roving IT company whom they call when there are problems but they have
had no problems (other than me) so they have not called the IT people.
I do now know if this router requires authentication. I assume I would
be presented with a request for name and password? I have been told
that there is not a need for signing up with their website nor for
entering any name or password.
I will try some other websites. I have been unable to contact msn.com,
msnbc.com, cingular.com, etc.
When I have done this, I will post it. It will not be before tomorrow.
Will you continue to monitor this thread or should I leave a note on
your blog? I left my personal email address there today.
Thanks for your work so far on this puzzling problem.
Ken
Ken,
I help here to keep up with the issues that I may deal with in person later.
Your situation is intriguing, and I suspect that I will end up learning as much
as you do.
If you post in this thread, I'll see it. Just reply when you're ready.
Since you say that you did get help (unsuccessfully) from a local expert, I'm
thinking less and less that the problem might be with the hotspot. If you find
it convenient to sometime visit the other hotspot, an "ipconfig /all" log, along
with the results from the 4 way test for a couple websites, will make a good set
of comparative diagnostics.
When you uninstalled ZA, did you get instructions from ZoneLabs?
