The final N was approuved on sept 11th 2009. I read a lot of review for a reliable wireless router. DIR-655 Xtreme N is highly recommanded. But it is still Draft 2.0. When the real n will be out to the market ?

[Sammydad1]

quick answer is probably 6 months give or take.

depends who has the final say in approval process.... and how many hundreds of items they have to approve.

It's already "Approved"

Hi,

The .11N standard is all that has been approved.  Each device that wishes to Claim Standard compatibility and therefore use the little .11N Compatible logo that they will issue must be approved by the people who issue the .11N standard, or perhaps their designees... I agree that politics probably has a lot to do with this process... who gets approved first and what-not.

I stated that it will probably take about 6 months for the IR-655 to get final .11N approval, and frankly that all depends on DLINK and if they even seek it for the DIR-655.  It is probably just as likely that they may issue an entirely new hardware device to hold the .11N standard "Logo" and they could easily keep the DIR-655 as a "Draft-N" device with only a small firmware tweak here or there.

I think many if not most of us would like to see the DIR-655 receive that .11N logo for standardization sake.  But in the interim, I would suspect people would rather simply have their units simply work right.

I don't think you read the link.

Now that the standard is officially released, the Wi-Fi Alliance should be releasing its revised 802.11n test suite any day now. But as earlier reported, products approved under the Draft 2.0 802.11n Certification process will be allowed to use the approved (non-draft) 802.11n logo without retesting.
So those of us owning draft 11n gear can celebrate today by just scraping the word "draft" off the boxes that our products came in. Enjoy your upgrade!

This means that by default, the 655 is a non draft device.

Hi,

I read only the first paragraph or two...  What you posted about the Not Having to Re-test is kinda scary to me....in the sense that if the DIR-655 was tested with FW 1.32 (which it likely wasn't) would it have passed .11N Draft 2.0 if it began dropping wireless connections or other issues were exhibited as people on these forums have made mention of....

Does anybody know what firmware the DIR-655 was using when it received .11N Draft 2.0 certification

1.03 or so IIRC.

[mackworth]

I am not sure it matters.  I always assumed that the test suite didn't test for stability and such.  Also don't forget that 802.11n has nothing to do with the WAN connection, so anything involving the internet isn't tested.  The only parts that are tested would be the associating wireless clients and stuff like that.

still waiting for the firmware for final n spec

still waiting for the firmware for final n spec

Waiting for what? It will not bring any other features or enhancements to the router...

still waiting for the firmware for final n spec

If the final .11n specs are the "final" one, the devices that were listed as Draft 2.0 and now automatically "11n Certified."   The "Draft 2.0" moniker is to be dropped but who really knows if / when D-Link will update the firmwares.

I hope D-link could clearify whether DIR-655 can be upgraded to final via firmware. If the old generation Atheros chip is able to do so, I am going to wait for the new firmware. Otherwise, I plan for a new product.


Other brand has already released newer models fulfilling the final n standard
e.g.
Buffalo WHR-G300N

Buffalo WHR-G301N

If the draft N specs are equal to the final N specs there really is no use in getting 'final N' firmware. So what makes this so important?

Equal? Yes, the current DIR-655 apparently fulfill the final N standard.

However, the part what I want D-link to clearify is the optional part.


e.g. DIR-655 supports SGI but it doesn't write it into the certificate. Of course, some features cannot be implemented via frimware upgrade such as 3 spatial streams.
How about coexistence mechanism? Does the "Auto 20/40 MHz" button mean so?
Shall D-link delete the "20 MHz" and "40 MHz" options?
Are there any other hidden optional features like this?

Shall D-link delete the "20 MHz" and "40 MHz" options? Probably not, the 20 MHz is still required for many wireless clients
Secure Guest Internet Access (SGI) Is already implemented in the > 1.3x firmware
SGI as in Short Guard Interval: Also already implemented IMHO
