It's possible that there are actual HW differences in the router. However thats DLink IP and I'm sure they wont enlighten us regarding that stuff. I presume that mostly its just FW and power adapter.

Hi to all,

HW/FW = B1 2.04EU

The 5ghz n signal is too weak to be used as a media network at my home.
So, I'am considering upgrading to (or better said switching from EU to NA) the 2.05NA firmware in order to gain some wifi broadcast power.
Does anyone already made a measurement of the gain between the EU and NA firmwares regarding this topic?

Tx in advance,

[FurryNutz]

There are wireless differences between EU and NA FW, mainly regarding some channels and frequencies. I presume there are other differences as well. Putting NA FW on a EU unit would probably make the operation of it not work well.

Tx for the answer Furry.

Nevertheless, I upgrated yesterday from 2.04 EU to 2.05WW. (I didn't try the 205NA cause I still  want to be sure that there will be no HW issues using this firmware)

This new firmware really rocks. Admin GUI response is quick.
And most important (but I didn't expect it), it gives me more power on the 5ghz n network (didn't try the 2.4GHz yet).
With the 2.04EU firmware I wasn't able to broadcast HD signals to my HomeVideo Set. The signal strenght was only 7% and the troughput was between 1 and 6 M. No way to watch a movie without masses of jerking, freezes, lost of sound,...

Without moving the router (same place than before I mean) now my signal strenght goes between 30% to 40%, and the troughput between 27M to 40M. I watched a full HD movie yesterday without any issue.

So, is it possible that the 2.05WW firmware uses the same broadcast power than the NA versions?

I need to make more tests during a longer period just to qualify that this gain of performance is constant or just a only due to some spacial esoteric chances ;-)

Glad the WW is working better for you. It's possible the WW has some of the same properties as NA however it's possible the EU FW wasn't up to part as it should be. Is the EU FW the latest FW for that region?

Quite difficult answer Furry ;-)

The official release in my country is the 2.01EU.
I get the 2.04EU from the german dlink site...
I get the 2.05WW from the rusian site...

So, i'am really not sure about whish version is official and whish is not...

To follow my tests, I get de SIR-825 running all the WE with the 2.05WW and still up and running, no issues at all. I also activated the 2.4Ghz Wifi network on (only on N) and activated a Guest Access.

What I have to mention is that running the router as a switch (linked to another router) have a real bad inpact on the wifi troughput... So to be able to broadcast a video withour jerking on the 5Ghz N wifi, the only solution I've found (since now) is to run the Dlink as a router... But maybe it's just a config issue. I had no time to play more with it...

I keep you posted if any new information about that by my side.

Regards

Ok, I presume that EU or WW FW should work on your router. NA has different wireless properties.

You can run the 825 as an AP however you need to turn off all options like DHCP, Firewall, QoS, WISH and such. However it's preferred to run as a host router and not an AP. If you need additional devices connected to it, I would recommend getting a external network switch. I have a 24 port Gb coming off mine and works great.

Keep us posted.

Funny. In my country D-Link WW or EU firmware, does not work properly with multicast 239.x.x.x  Only russian version is good for my needs.
