Since this computer has group policy,
it may very well have some site blocker. Ask your admin.

Interesting - the wierd thing is that I am the admin, it's not part of
a network of PCs, it's my personal computer, and I have no idea why it
has a group policy or even how to switch it to individual policy. Can
you tell me how to:

1. See if there is a site blocker.
2. Turn off the group policy.

Thanks!

Adam

Did you check if there's anything in the HOSTS file?

What is the HOST file and where would I find it? What I don't
understand is why the computer worked fine when connected via hard-
wire to the cable modem and now that I'm going wireless it wont load
certain sites. This implies it isn't a firewall issue or a site
blocking issue because then the web sites wouldn't have worked in the
hard-wired case. It almost seems like something from a Windows setup
perspective is hosing the wireless network from communicating with the
browser.

Ok, based on your reply below, I conclude that hosts file isn't the culprit.
FYI, hosts file is located at C:\WINDOWS\system32\drivers\etc

Is your cable modem also a wireless access point?

I agree. So you've narrowed down the problem to wifi connection. It's either
the wifi adapter on your PC or your wireless access point configuration. Are
you using the latest driver for your wireless adapter?

John,

The cable modem is not a wireless access point as far as I can tell.
I'm not convinced it's the adapter because the other PC works
perfectly with the same adapter (literally just switching the dongle
to the other PC's USB input port). When you say the wireless access
point configuration, do you mean the router itself? If so, I would
argue against that for the same reason as arguing against the adapter/
dongle. Is there a "wireless access point configuration" in XP? That
seems the likely problem since the setup works fine without wireless
and barfs with wireless using the same router, dongle, and browsers as
the PC that works with the wireless.

Thanks again for all the help/discussion!

Adam

Good point, Adam.

So the problem is narrowed down to the PC itself. The fact that you must use
gpedit.msc to disable wifi is a bit unusual. A standalone computer normally
doesn't have any policy imposed on it. Did the computer ever join a domain
once in the past? It might have picked up a filtering policy from a windows
domain. But that doesn't explain why you have no problem surfing when the
computer is hard wired. Weird.

One last thing that you might want to try is to manually uninstall wifi
adapter from that problem computer. Restart and reinstall wifi adapter.
Restart and (re)join your wifi network. I'm getting as confused as you are
now. Sorry.

what other, if any, IS are you using, Norton, AVG, Kaspersky etc. Do all
comps have the same IS. If so are all set to accept the same apps. Sorry but
why have a group policy if its only your home network.

You say for a number of web sites you try to connect via a
browser.............is there any other way ? What is your browser and do
you use the same on the other comps.

Hi
First step is the insure that you have a Wireless connection between the
Computer and the Wireless source.

OK a bunch of answers:

1. I used gpedit.msc to disable the Windows firewall. I have no idea
why it had a group policy, I didn't set the computer up originally, it
was a "hand me down".
2. I did try a full uninstall-reinstall and still no luck. When this
didn't work I reconnected the wired network access (no wireless) and
it works like a champ.
3. The only other software I'm using is Norton for anti-virus. Both
computers are running Norton, same version and both fully updated
(same installation disks) and neither have any outgoing firewalls
running.
4. For browsers I've tried IE (7 I think) and Netscape 7.2, both
exhibit the same behavior.
5. I definitely have a wireless connection as I was able to ping over
the wireless.

Adam, I am still a little confused with your statement where you say you
can't connect to "some" web sites.............does this mean you can connect
to some while on wireless.

If ever I have a wireless connection problem I always reset the router. That
is, switch it off, put paper clip into the reset hole and fire back up while
maintaining paper clip pressure for at least 10 seconds. I think most
routers use this reset method. Then go through the routers finite setting to
install any security WEP or WAP passwords. Then re-establish settings on the
notebook with the same passwords etc. Also make sure you have the channels
set the same and infrastructure mode enabled.

Remember, to close down and restart after any adjustments. This is the cure
for 90% of connection problems.

Yes you are 100% correct - I can connect to some web sites, like
msn.com or geocities.com, while others wont connect while on the
wireless network and I get a Windows XP message about unable to
connect, maybe I typed the URL wrong or that the site is down or that
the network is down when none of which is the case. I have tried
turning the router off and then on with no luck though I haven't tried
the reset you describe. The kicker is the other computer works with
the wireless just fine so I doubt the network is the problem. I'm
fairly certain there is a configuration issue on the PC side but for
the life of me I can't figure out what it is.

but like you say if it is only happening to some web sites then what can it
be. I am out for a while but will continue to think.

Right, that's the wierd part. I'm wondering if there is either some
sort of packet dropping, filtering, or just slow web sites due to
scripts/Java/whatever that is causing the browsers to be "time out" on
the page load where this doesn't happen on a direct network
connection. Aside from that, I'm stumped.

A few things:

1) If you have SP2 / SP3 installed, the Windows firewall will
automatically be active once your PC is first booted with this Service
pack installed.

2) Some "newer" anti-virus software adds modules to scan network
traffic. Check in your anti-virus system

3) If you use some type of Internet security software (such as Norton
360,) there might be a module added to your network adapter
configuration which will "filter" the traffic.

4) Also with some Internet security software (IE: Norton 360) some
newer firewall modules might need to be told to "trust" the wireless
SSID. Otherwise, check the router's status logs for the
"deauthenticate" message(s.) If you see one, then your software
firewall is at fault.

Some websites being accessible while others are not is symptomatic of
the MTU problem detailed here.

Jim,

I tried the utility but had no luck - is it a CISCO only thing?

Step 1 -- Yes, it CISCO only change but you can "adjust" it to meet
your router's settings.

Not as far as I'm aware.

It was a fairly common problem a while back causing *some* computers
to have problems with *some* websites when using *some* isp's but not
others.

It's also adaptor specific and so might happen on wireless but not on
wired. Just like yours.

Perhaps you might try the tweak test at
http://www.dslreports.com/tools
with both your wired and wireless interfaces to see if that throws up
anything interesting.
