Hey Dlink,
I'm sure you hear all sorts of good ones thoughout your days. So here's another.
I'm currently using a Dell Latitude D610 laptop with a DWA-652 card to get Wireless N speeds. (it also has an internal Dell wireless-G card). OS is WinXP with latest updates.
DWA-652 driver version is 1.30. Not using the Dlink site manager.
For some very ODD reason, I am unable to access Logitech's Universal Remote website http://www.myremotesetup.com and/or use their software even though any other website or network application works.
I know... check with Logitech. But hear me out first.
If I disable the DWA-652, and use the Dell internal card, it works. It seems to only be an issue when using the DWA-652.
Other computers on my network have no issues accessing the site either.
- Windows firewall is disabled (by corporate GPO)
- tried with/without Antivirus (Mcafee)
- no other spyware or software based firewalls are installed.
- there are no exclusions, filters, etc configured on the station or on the router.
- Not browser specific. Occurs with IE and FIREFOX.
I am even able to drop down to the CMD prompt, and successfully TRACERT www.myremotesetup.com with both the internal dell card and the DWA-652. Yet it won't load the webpage or the application, which by the way, doesn't use any special ports. It's on port 80.
I'm at a loss.

Nobody has anything to offer here?
Someone else on another forum working on a Mac, noticed that the problem that I (and several others) am encountering seems to revolve around scaled and large TCP receive windows.
This other person successfully found a workaround by running the following in terminal on their Mac:
sudo sysctl -w net.inet.tcp.rfc1323=0
This apparently disables scaled windows and sets the receive window to 64k (the default).
Being that I am on WinXP, I wasn't able to apply this work-around. Does anybody have any input on this?
Cheers

Hi pure_energy1,
I can give this a test tonight when I get home. I have a logitech remote and can put the software on my laptop instead of my desktop. I had to fix my issue first before I could assit.

Wonderful! I look forward to seeing your results.
For a valid comparison, I am running v1.30 of the DWL-652 driver, and firmware v1.11 on the DIR-655 router with WPA.
Thx!

Just for clarification, do you mean DWA-652 and not DWL-652?

OOOPS... Yes, you are absolutely right, I meant DWA-652, not DWL...
I have changed the heading respectively.
Thanks,

It all works for me. I wonder if there is some sort of proxy setting configured in your browser for that adapter that is not there on the other (or vice versa). Check in IE under tools --> Internet options --> connections --> [Lan settings]. If anything is set there, this would be a good place to start looking.

Hmm.. strange... are you on the latest firmware / drivers for both the router and the DWA-652? Lemme know what versions you're running so that I can downgrade if need be to try it out.
There are no proxy settings configured on my machine.... and wouldn't that affect all traffic, not just this specific logitech site? I have not problems accessing ANY other site, including www.logitech.com.

I am using DWA-652 Driver 1.30 and DIR-655 Firmware 1.11.
There still could be config specific to the card. If you double click the wireless icon in your task bar it should bring up a status screen. Click on properties. What is listed under "This connection uses the following items"?
You could select "Internet Protocol (TCP/IP)" in that window and click properties. From there click [Advanced...] --> Options tab --> select "TCP/IP Filtering" then click [Properties] Is anything listed in the TCP/IP Filtering page?

That was one of the first things I verified. There's nothing listed in the filtering page, it's set to permit all and the filtering checkbox is not checked. There are also no filters for this IP / MAC address in the router either.

Have you tried clearing your browser cash and deleting your cookie from the website?

Yup, also tried using different browsers (IE, FIREFOX).

If you are familiar with regedit, what are HKLM\System\CurrentControlSet\Services\Tcpip\Parameters\TcpWindowsSize and MaxMTU size set to?
Regards,
Karl

If this is related to rfc1323, you could look at the Microsoft support document http://support.microsoft.com/kb/224829 or do a google search onr rfc1323 and windows for more ideas.

TcpWindowsSize is at 373760 (5b400 Hex)
MTU is at 1500 (couldn't find MaxMTU)

I set mine to match yours, rebooted, and am still working. I think you really need to work with the site owner to get this resolved. Anyone else here have any ideas?

Hmm...
I have already contacted logitec with regards to this issue, as have many others. What's curious about this issue is that it works for many, and doesn't for others.
I'm going to attempt re-installing the DWA-652 driver and see how that works out. I'll let you all know.
-
Well, as I was about to re-install my driver, I received a message from Logitech stating that their IT staff resolved the issue on their side. I'm still curious why it affected some and not others (for example you bspvette86 and I who have similar configs)...

Thanks for the help anyway. :)

Were you both using Cable modem connections with light authentiaction on the packets? Or did one of you have a nice size payload of authentication (DSL PPPoE) on every packet?
You only discussed networking hardware and code, Browser brand (not necessarily versions or added extensions), and a couple windows OS settings. There are a few more things that may still be different causing the different results.
IDW4U as it relates to D-Link hardware. Instead of IDW, which means we have to makes changes to the product.
It Doesn't Work.

Veyr true, and at this point, we'll probably never really know what the root cause was since Logitech has solved the issue on their side.
-
There are a large number of reasons why that could be the case. I have actually been working similar issues at work recently in the process of doing a data center move. In some cases it was MTU size related, some it was sticky source load balanced related, others just luck of the draw. The good news is they fixed it for their customers.
Cheers!

Either way,
Thank you very much for your help in this, much appreciated! :)
