D-Link → DIR 825 failed vista UPNP test

I posted this over at Dlink's forum and got no responses yet. Here is a report from Microsoft's website that tests routers for Vista compatabilty. Any thoughts on why this router failured this test would be helpful. FYI UDNP is enabled and I am running firmware 1.01.

I reformatted this slightly for readability. Scroll to the end for the UPNP details.

My DIR655 paasses just fine on firmware 1.03 (This firmware works best for me, I have tried all the others)

Basic Internet Connectivity Test

This test is intended to ensure that your computer has basic Internet connectivity, which is needed for the rest of the tests.

A result of "Supported" indicates that your computer has basic Internet connectivity. Supported.
Network Address Translator Type

One primary function of most home Internet routers is Network Address Translation (NAT). Routers providing NAT support assign private IP addresses on the local network. NAT maps these private addresses on the inside network to a public IP address on the outside network so that computers behind the Internet router can communicate with the rest of the Internet. Since Network Address Translators can work in different ways, this test uses Microsoft servers to identify your router's NAT type. Some protocols work better through routers that act as cone-type NATs than routers that act as symmetric-type NATs.

Success of this test means that your Internet router or firewall acts similar to a cone NAT. This means that it helps applications which use Internet Protocol version 6 (IPv6) to connect, regardless of your ISP's IPv6 support. For example, in Windows Vista you can collaborate with others across the Internet using Windows Meeting Space.

Supported.

Traffic Congestion Test

Internet routers sometimes lose information that is being transferred across the Internet when they experience congestion (full router queues). This loss of information is known as packet loss. Internet protocols like the Transport Control Protocol (TCP) can use packet loss as a congestion indicator. Explicit Congestion Notification (ECN) is a mechanism that provides routers with an alternate method of communicating network congestion. This notification effectively reduces TCP retransmissions and increases throughput. This test attempts to download a short Web document, first with ECN enabled and then again with ECN disabled. If both downloads succeed, the test passes, which indicates that your Internet router successfully allows packets through with ECN options set.

A result of "Supported" indicates that your router can work with this new Vista Feature to improve download speeds and increase endpoint connection reliability. Note You would need to explicitly enable ECN on Vista to take advantage of this feature.

Supported.

TCP High Performance Test

Window scaling is a Transport Control Protocol (TCP) option introduced for addressing performance problems. Some Internet routers cause TCP data transfers that use window scaling to fail, particularly when there's a mismatch between the scales chosen by two computers transferring the data. This test downloads a series of Web documents of increasing length until either an incomplete download is encountered or all downloads succeed. Success indicates that your router allows Windows Vista to negotiate the best data transfer rate and help improve download speeds.

A result of "Supported" means that Windows Vista automatically uses window scaling to negotiate the best/largest data transfer rate and help improve download speeds.

Supported.

UPnP Support Test

Many applications need to open ports (allow incoming traffic) through an Internet router, particularly when both communicating endpoints are behind different NATs. Modern routers allow hosts to create such open ports using Universal Plug and Play (UPnP). This test ensures that the router has UPnP enabled, can support a reasonable number of open ports, and can maintain these settings.

If this test does not succeed, experiences using certain programs may be degraded. However, your basic Internet connectivity should not be affected. .
Multiple Simultaneous Connection States Test

Not supported

This test creates 80 concurrent TCP connections to external Web servers and keeps them alive over the period of two minutes by attempting continuous data download using HTTP. Passing this test indicates that your router robustly supports multiple computers or programs accessing the Internet simultaneously.

A result of "Supported" means that your Internet router can handle a large number of simultaneous connections. This will enable you to connect to the Internet reliably using multiple applications or multiple computers. Also, your experience with applications that use multiple network streams (like some file download/sharing programs) will be enhanced.

Supported.

Congratulations! You have basic Internet connectivity and browsing, and your Internet router should work just as well with Windows Vista as with your current/previous operating system. However, some of the new Windows Vista features are not currently supported by your router.

The More Information link above can give details about the features of your router tested by this tool, and the Windows Vista features and scenarios which can be enabled. If you are interested in getting the most out of Windows Vista networking, your router's manufacturer or your Internet Service Provider may have an update for your router that will enable these features. There is also a link below that can help you to find Internet routers that are tested and certified by Microsoft to give the best experience with Windows Vista.

I realized before I went out I was 28 day into to my 30 days and returned it to Best Buy. I am not sure what the problem was but my 655 will be back in service for now.

Hi jrouss,

My 825 hw:a1 fw:1.01 passed all the tests, did you try resetting the router or rerunning the test?

The test shows two IGDs detected. Was the DIR655 or some other router also on the network when this happened?

Yes, I was using my 655 as a switch. I would have liked to had longer to mess with it but, I didn't want to deal with RMAs if the router was buggy.

Ah.

The problem probably could have been solved by turning off UPNP in the DIR-655. UPNP and DHCP needs to be turned off in any router acting as a switch.

I have been checking back on this out of curiosity. I did not think to try turning off UPNP on the 655 and I do know I had it on, this is good info. I now have a Zyxel X-550 in the place of the DIR-655 that I am using as a switch that seems to be fine. I will have to see whether I have UPNP on or not and retake the test with it on and off and see what happens.

It passes with my X-550 and UPnP enabled. Not that it may have affected the DIR 825 but, the DIR 655 with tthe fhe older firmware is rock solid for me.

Probably because the two devices had two different UPnP designations --

Still, enable UPNP only on the WAN device. Otherwise your UPnP software may uselessly read and control the wrong device at best and may ignore the correct device at worst.

I appreciate the replies and learned something. Have a good holiday.
