Im quite sure the limitation is only software wise. hardware limitation would be quite odd. even my old dgl 4300 can do qos on more than 2mbit/up.

im currently try to figure out how to pack the fw again. that is not quite easy because of checksum checking.

I downloaded the GPL Code from the German Site but it is quite old (Ver. 1.0) and has no webinterface files. (so wee need to extract them from original firmware.)
The Dlink.com.tw site has a newer GPL Pack but the download is horrible slow (10kbyte/s) and stops half the way.

the bin file seems to be an uimage format containing multiple gzip crompressed images.

to extract them you need an linux environment.
All credits go to doze from hardwarefetisch.com. He helped me alot!

for the extraction you also need some tools.
1. binwalk https://code.google.com/p/binwalk/
2. cpio (install through packet manager -> apt-get install cpio)

Here are The steps:

1. binwalk -y gzip firmware.bin

binwalk will show you all sections with offsets noted at the left row. note down the one before the last one. should start with 4....

then extract the sections with dd.
dd if=firmware of=rd.gz bs=OFFSETFROMSTEPONE skip=1

This  creates a file named rd.gz

Lets extract the archive.

gunzip rd.gz

Now we have a file named rd.

run:
binwalk -y gzip rd | tail -n 2 | cut -s -f1

Note down the Offset Number.

extract again:
dd if=rd of=rootfs.gz bs=OFFSETFROMSTEPABOVE skip=1

unpack:
gunzip rootfs.gz

creates file rootfs

Make Folder for filesystem extraction:
mkdir fs

extract the cpio archive:
cpio -ivd --no-absolute-filenames -F../rootfs

done.

also quite interesting is that is seems that is possibly to build a firmware based on openwrt.

// edit

i tried for days getting the source code to compile on my ubuntu. but no luck.
then i read the included readme again. i overviewed that the used fedora 8 as build system.

okay installed fedora 8 and it compiles now.

when im able to mod it to my needs i will post

also quite interesting is that is seems that is possibly to build a firmware based on openwrt.

Been thinking about this, too. But to me it seems like OpenWRT is very hardware dependent - and the DIR-857 is not on the list of supported devices, currently...

When you compile the GPL Source there is an option where you can choose between the Ubicom System or OpenWrt.

[shm0]

okay here we go.

sadly i was unable to merge the extracted files into the 1.0 firmware source.
but anyways the gpl source does include the webinterface.

so i started to mod the 1.0 Firmware.

here some pics:

automatic upload speed:



manual upload speed:



And it works.

So please forward this information to D-Link so they can change it. thank you.
Or someone knows where to get some newer source?

here is the Firmware.

DOWNLOAD REMOVED (why is it gpl then?)

[FurryNutz]

This issue has been already brought up to the attention of D-Link.

There are different regions so I'm not sure that your region is aware or knows about it. I recommend that you phone contact your regional D-Link support office and talk to someone at a high level, say 3 and refer this to them. Our region is aware of it and we do not know when or even IF, they will do anything regarding it.

I'll as you to please remove the download link. We are not approved to post any links to un-official FW. Keep your files and data on hand to possibly send to D-Link for review.

Maybe Ambercap can help in compilation processes. Should this be approved by D-Link then we would post links when and IF D-Link posts any such approval.

Again, this is for your region and presume this could be for all regions however lets take this step by step.

Thank you.

yeah i gave up on the german dlink support. they just dont care. the last fw released is a year old?
the doesnt even take the bugfixes from other dlink sources (eg. North America).

And im quite sure that using a firmware for different region doesnt harm anyhting. the hardware is the same in all countries. the only difference are maybe the channels for wlan.

and they all use the ubicom distro tu build there firmwares.

i running the 1.04 and it was running nicely here.
Why isnt the GPL Code avaible on the DLink Us Site?

download link removed.

[nestolea]

There are people who care. It's just very tough to get to them...
I was lucky to get a contact mediated by an editor of the largest German computer magazine. This contact was the first support person to really help me solve my problems...   

Concerning the firmware, he explained me why the newer versions available in North America are of no use in Europe. Or at least part of it. (Nevertheless, this is no excuse why there is no newer version available for Europe!)

Great that you could manage to modify the firmware!   

What is the difference between GPL source code and ubicom distro?
I don't understand why one can choose between ubicom and openWRT when compiling the source: openWRT is a router operating system by itself, isn't it?

[shm0]

The GPL Source is/include the Ubicom Distro.
The Distro is just an enviroment to build the firmware.
It is based on a linux 2.6 Kernel. which is optimized for hardware. I think.

Yes openwrt is a linux based router operating system.
uCLinux is a linux based router operating system which is was created by ubicom

With the Ubicom Distro you can choose which system to build.

I hope i make it clearer now.

Yeah im quite happy with the mod. I will use until a newer firmware with QoS fix is avaible or i get my hands on a newer source.

I just bought the router because of the amazing QoS. (i loved my old DGL 4300)

also interesting is that there is limit of 50000 (!) connections and 256 stream queues what is quite impressive.

Hi,
German D-Link Support finally answered my Ticket.
They Said that there is a 2mbit limitation but there are no Plans to remove / improve this.
So my last Hope is the dlink Support from USA Or canada.
Or someone Knows Where to get the Source of a neuer Firmware then 1.0.

[FurryNutz]

D-Link USA is aware of it however I have not hear any information regarding it. I presume they may or maynot do anything about it. As new routers come out to market here, I've noticed that they are using the newer QoS model as seeing when the DIR-645 came to market and all follow on routers seem to be using this model. So going back to re-designing the current Amplify line may or may not happen based on feasibility, HW and other factors. We can only hope.

Only thing we could attempt is have someone do a "Work Around" here which would not be supported.
