Bill S.
So, I got back from my trip on Friday and fired up the laptop here at home on Saturday. I have a wireless access point that I use with the laptop and one desktop machine - the other desktop is hardwired to the router. Router and access point are separate units.

The laptop will access every website I try - with the exception of any Google site. I can ring up DNS for google and get a good address, and I can traceroute from the laptop to Google. Desktop that is on the WLAN acts the same, hardwired desktop accesses everything fine. Plugging the laptop into a hardwire port results in access to Google and everything else.

So, that would indicate that the router is working OK, and the problem would be in the WAP. Reset WAP, no change. Upgrade WAP to latest firmware. No change. Maybe the computer drivers have been hijacked.

Run virus scans (2 different providers, thanks companies for making free scans available on the net), run four different spyware scanners (adaware, spybot, Windows defender, webroot) - all scans come up clean. Ran all in safe mode, just to be sure. Downgrade the WLAN driver on the laptop, and install fresh copy of the latest driver. No change. Also uninstall and reinstall ZoneAlarm. I also disabled all the "startup" items that could affect it, such as the VPN client, etc.

So, I'm running out of time and patience. The laptop (and WLAN desktop) won't access any Google site (including their advertising servers, causing a "hang" when loading many ad-supported sites), but only through the WLAN. Hardwire, it's fine. And yep, it worked fine on the trip, the last two hotels had wireless access only, as did the NWA lounge in Detroit.

The issue is a "hang" (white screen) as opposed to server not found. Using a text-based sniffer, the command goes out to Google, but nothing comes back. It affects both IE and Firefox, along with SamSpade. So that would indicate a network layer issue, rather than cache or cookies. To be safe, I cleared both cache and cookies (now, what were those passwords again?).

Beats head, sits down, tries ensure low blood pressure at AME appointment....

Any thoughts?
 
is google.com resolving properly to 72.14.207.99 ?
What happens after you flush dns?
 
Sounds like you've covered most of your bases.

Everything I was about to suggest I read a little more and you tried it...

Here is what I would try.. First off uninstall ZoneAlarm and see if it works. If it doesn't work download:
LSPFIX from http://www.jesseangell.com/downloads/LSPFix.exe
OPEN LSP FIX AND JUST CLICK FINISH. REBOOT. DO NOT DO ANY OF THE EXPERT STUFF

Another thing worth trying is click

1.) Start
2.) Run
3.) Type in CMD hit OK
4.) type in: telnet google.com 80 PRESS ENTER
5.) type in: GET /HTTP/1.1 PRESS ENTER

You should see a big long response...

If you don't get the response..It's something really jacked up with the windows networking stack..See if the LSPFix does it..If not..Bust out google and prepare to spend some time on it :)
 
So, tracert works, resolves to proper IP addy, right?

What happens if you try to open the Google IP address directly?

What brand & model AP?

This one's weird, mein freund.
 
Interesting, I get nothing when I do that but my connection is fine

Flush DNS provides the same result.

Google resolves to 64.233.179.99 or 104.

Using the 72. address you posted produces the same result (works hardwire, no work on either wireless).

Jess,

Microsoft has built a stack rebuilder in SP2. I ran that early on in the process. No success. I'll try the LSPfix, but not holding out a lot of results.

As for the telnet command, I've already tried that, there is no return on the wireless, it works OK on the hardwire. (BTW, SamSpade provides a nifty text-based window that lets you look at the code going and coming on a website. Same basic function as Telnet, only easier).

The stack shouldn't be messed up on two machines.....

I'd bust out google, but it looks like I'm stuck on Yahoo. Since so many tech sites use ads served by Google, even that's a source of frustration over the laptop.
 
You reset the WAP - did you reset the router? Is the router also a switch?

How about plugging the WAP into a different port on the router?

Yeah, I can trace it fine. DNS resolves OK. But nothing comes back even with the numeric addresses.

Worked fine before the trip.

Weird.

Yes, yes, and yes.

The only thing I haven't done is put the WAP on the second router that I use as a VPN endpoint - will have to reconfigure IP addresses to do that (I set the WAP as a fixed address, and due to the VPN endpoint, the second router is set to a different subnet).
 
Jesse - LSPfix finds no problems, just as netsh didn't. Uninstalling Zonealarm causes no change.
 
Not a good way to spend your birthday...hope the rest goes better Bill. :)
 
Well, I have now proved that it is in the router or WAP hardware on this end, as I tested the laptop wireless on a WAP outside of the premisis.

One of the boxes must be filtering those addresses. Weird. I did clear out all the keyword filters (spam, advertising, and malware sites) from the router, to no avail.

Next step, I suppose, is to put the WAP on the second router and see what happens. May not have the time to try that until this evening.

As do I... ;) I keep hoping for a job offer as my B'day present, but so far, nada....

Hmm. It was working for me earlier. I wonder if I setoff some google security deal or something..Now it just instantly closes the connection...

This will work though

[root@jesseangell jesseangell.com]# telnet google.com 80

Also works in the windows telnet client. After you type that GET command you have to press enter twice.



btw

Did you try a hard reset on both the router and WAP?

Yeah. I upgraded the firmware on the WAP - it requires a hard reset post-upgrade, along with full reload of all settings. PITA. Running latest rev on the router. Don't have time to move stuff around right now.
 
Man this is weird. Sure sounds like some poisoned DNS cache entries to me. Since you seem to have flushed them out of the router and AP, does Windows keep a local DNS cache for each connection type? Perhaps it got corrupted in the AP or router (or heck even your ISP) previously and Windows is keeping a copy of that while your're connected wirelessly?

-Rich

/scratches heaad
 
I asked him - he said it did nothing.

Bill that was a ipconfig /flushdns from command prompt right?

Correct.

And I'm now convinced it's not in the laptop itself since it worked OK on an external-to-the-premesis WAP. Also flushed the DNS on the name server, as well as manually specifying a different name server. IIRC, Windows uses the same DNS cache whether it's wired or wireless.
 
Yeah, it's mine. Though I can see one or two neighbors WAPs.... one is open, the other not. I do have mine locked down pretty well.

I'll be looking more at it this weekend.
