Can you use the NA firmware on an EU firmware device?
I assume yes, since the hardware is the same
What's the difference between the two?
Thanks
-
i don't know exactly what differences there are but i do know that when you use NA firmware on a router for the EU there might be unsolvable problems after the upgrade.
i use EU firmware only ;)

OK, I'll got with the 2.05 beta one then, people seem to think 2.05 is OK.
-
including myself, it works good here :D

I'm not an expert, but I believe the EU firmware allows 2 additional channels 12 & 13 however it also limits the wifi broadcast power(I assume because cities in Europe are usually more densely populated).
Unless there was a bug fix in the EU version that you absolutely needed I wouldn't use it in NA.
-
can anyone tell us what differences there are talking about the transmitpower? if the NA firmware gives a wider range to both radio's and don't destroy some of the routers parts why shouldn't we use that on B1 EU router versions?

It's not a router hardware issue. It has to do with the different standards and regulations in EU and NA.
I assume EU gives you 2 extra channels because of dense population so you have more chances to find an open or less crowded channel. However a stronger transmit power (EIRP -Effective Isotropic Radiated Power) in EU could possibly cause interference with your neighbors.
I would say use a tool like inSSIDer to check wifi signals around you and make a judgement about which firmware to use.
-
Okay thanks for the answer, if i understand you well then it's up to the user about which FW to use? stronger transmitpower can be helpfull if you have some signal weakness in areas of your home or office so if you think more power can solve that it's no problem to use NA firmware?
-
"Legally" you're only supposed to use the firmware for your location, but if you know there is no chance of you causing interference for your neighbors then it's up to you if you want to experiment to find which firmware gives you better performance.

My EU router wouldn´t even talke the NA bios when trying to program...
-
There are major differences between NA and EU routers. You need to use NA for NA routers and EU for EU routers. You can't cross platform them.

My dir- 825 came with firmware v2.01EU installed, i was not happy with that firmware, so i upgraded to
v2.0NA (via recovery menu)
Everything worked kinda good, but i had to reboot the router every week, so i decided to upgrade.
Now I'm on v2.05 and are very happy.
So, both EU and NA worked for me.

Do you have any proof to verify your statement?
It's clear from reading this forum and the DD-WRT forum that many EU DIR-825 users have been using the NA firmware without problems. Legally they're not supposed to use the NA firmware in EU but nothing in the hardware will prevent it from working.
-
Legally there are wireless differences between NA and EU in which are set down in rules between the two continents. The Wireless uses difference frequencies which I presume try not to over lap and cause issues in the perspective countries and interfere with there perspective frequencies. Not sure if WRT follows these rules or not.
-
I was referring to your "There are major differences between NA and EU routers" comment. I thought maybe you had inside info that the hardware was different. Technically only the firmware and power adapter have to be different and I believe this is also the case with Netgear routers.
I already addressed the legal issue earlier in the thread. DD-WRT has NA(North America) and WW(World Wide) versions of their firmware.
-
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,
-
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.
