Ya I tested this out last year and saw way faster speeds when I was testing on AC and N modes and my NAS was a PC acting as a file server.  

What is this building made of? I'm wondering if the building material used are having an impact on this.

Any chance you have a friend or family where you can take the router and test it outside your building? Might be a good test to see if the problem follows or not.  

Some info on EU 5Ghz channels:

This building is made of brick-walls and wooden-floors.
I think maybe the plumbing-pipes, the heating-pipes and electrical-wiring has more impact than the brick-walls and wooden-floors.

Of course testing outside my building is always possible, but that takes a lot of time, as my friends and family doesn't live nearby. So I prefer not to do that.

Depending on how the building is designed and such, anything could be effecting the router.

Understand about not testing elsewhere. Sometimes you can't.

Hi again 24zeven,
I am afraid I didn't make myself clear about testing the wireless throughput.  I was looking for a comparison between the wifi throughput rates between the old and new routers to see if you would actually be getting a better transfer rate regardless of the signal strength indications.  The other problem with your test was that the limiting device in your test is likely to be the NAS.  Even though your NAS is a good brand and likely has a gigabit ethernet port, the CPU, is generally going to be the choke point for the throughput.  What I was trying to suggest was not just compare the 2 routers but you would probably need a test between say a laptop with and AC adapter and another computer, hopefully with a gigabit ethernet port.  It is the actual throughput that you are interested in, not just the relative signal "strength" rating.  I hope this is a bit clearer.

Hi Cable 2.
I can't follow you completely.
I know the download using wifi-N speed of the old router was about 2-3MB/sec.

I don't think that the NAS his output is this low...
I had a Desktop until 2 moths witch was connected using LAN on the old router. And the network speed was great. I forgot what the figures were. To bad my desktop died, with hardware failure (still working on it).

So what I understand is, that you want me to test this for my old and new router - Correct?:
Laptop WLAN-AC -> router -> LAN PC  (and other way around.)

Hi,
I was trying to see if you could use some free tool like the lite version from here:   http://www.totusoft.com/lanspeed1.html
to see if the transfer speed with the new 868L was the same or better than the throughput/ speed with your older Dlink.  In other words swap the routers and run the test between the wifi from your laptop with the AC adapter and some other computer hopefully with gigabit ethernet.  If you use a NAS, you might see a difference but not as likely because of the NAS hardware, i.e., the low power CPU.   Unless you can get another computer to run the test, there is no way to determine if you are getting improved wifi tranfer speed or not.  I don't really know how better to explain what I mean.  My guess is that you may be getting the increased speed / throughput even though the signal strength is slightly less.  The point is you might put an old B speed router on your setup and it may well give you an increase in signal strength but you will still get better throughput with a g or n speed router regardless of what the signal strength might say.

Any status on this? 

Compared to my Linksys 610N with DD-wrt on 5Ghz (wifi-N), the signal strength does'nt seem to be better.

I compared the to signals with the routers next to each other 5 Ghz-only.
InSSDer gives me an signal strength for both of 50 dBi when I'm connected.
(note that wifi radio on 2,4 Ghz is of in both cases.)

As the DIR-868-L has Smart Beam; I expected at least an signal strength of 48-49 dBi.

Can anybody explain why the signal-strength is'nt better? Or is the SmartBeam technology as an extra over it's competitors just an sales-story?

Thanks for the link.
I'm a bit busy at the moment, but will take a look at it later. 

[24zeven]

Any status on this? 

The connection is still the same.
Someone told my that smartbeam means that D-link has an advantage over wifi-g, because there tech is "backward compatible".
Wifi-n and ac standards have something like smartbeam standard build in the code.
So for me this means; no additional signal strength as I was comparing to 5Ghz-n (6 year old router).
I replaced my old router to an other floor and set it up as an bridge. It's wired with a cat 7 cable to 868L.
Now I have good range in my complete apartment using 2 radio's over 5Ghz.

Glad you got it all working.

Enjoy.

...to see if the transfer speed with the new 868L

Here is also some test info of this and other routers:
Hardware.info
--

My own test:
868L
-> PC (LAN 0,5 m CAT 6 cable)
-> Old router 610N (Bridgemode - LAN 15 m CAT 7 cable)
     ---> NAS (LAN 0,5 m CAT 6 cable - connected to 610N)

For the test I had my Laptop about 0,5 m closer to the 868L that the 610N, still the radio of the 610N was better 
radio 5Ghz AC: Laptop - 868L: 45 dBi
radio 5Ghz N: Laptop - 610N (DD-WRT): 38 dBi

Speedtests:
WLAN - LAN PC
34 Mbps (writing) / 28 Mbps (reading) -> router: 610N
55 Mbps (writing) / 94 Mbps (reading) -> router: 868L

WLAN - LAN NAS
27 Mbps (writing) / 19 Mbps (reading) -> router: 610N
45 Mbps (writing) / 22 Mbps (reading) -> router: 868L

Note that my laptop and PC have an SSD, the NAS has a HD.
I measured a lot of scatter: reading speeds of over 250 Mbps, but also 20 Mbps using WLAN - LAN PS, router 868L!

[FurryNutz]

Can you provide a link to an English text version of that? Looks like it came in 6th place. I see the 880L tied with the Linksys 1900AC.

[24zeven]

Here is an test in English. -> uk.Hardware.info
It's basically the same comparison, only the one written in dutch has more routers in it...

[FurryNutz]

Thank you.
