I installed LEDE 17.01.4 on my EasyBox 803A (ARV752DPW22).
Everything works including wireless except ADSL with T-Online (annex j)
If I use the firmware of the Speedport W504V (ARV8539PW22) then it works but wlan doesnt work (beacause the Speedport has different wifi hardware than Easybox).
I already use vlan tag 7 for wan interface as you see in my configuration:
config interface 'wan'
option ifname 'nas0.7'
I tried to adjust the network configuration like in the thread you mentioned but it didnt work.
If I use wrong firmware for this router (for w504v) then it works with the configuration above. But with the correct firmware it doesnt work. Maybe it's a driver problem?
But the problem at some Lantiq devices are: Although the chipset supports all of ADSL Annexes, but there have extra limits "Filter ?" that prevent to use some Annexes.
I am really interessted to it, but no one knows somthing concret things.
I fear your Router can without soldering Annex B only.
My source a this post
Background: Normally it exist 2 variants of DSL binary firmware Annex-A and Annex-B (i am not shure but the Annex-A is normally used for M, L J too)
These Packages have one sort of the firmware (for example annex-b) + binary patch to build the other annex (patch to build annex-a variant).
If you install the B variant (https://downloads.openwrt.org/releases/17.01.4/targets/lantiq/xway/packages/kmod-ltq-adsl-danube-fw-b_0.1-1_mips_24kc.ipk)
And use option annex 'a'
then the LEDE scripts build automaticly the annex a variant from the B-firmware + A-Patch and use them.
With the parameter "option firmware 'PATH'" you can override the procedure and use exact this firmware what you have specified.
For create the counterpart per Hand use the bpatch utility of your router.
You can try to install the other annex of your Firmware and try use them, or with other words test so much firmwares if it works.
note: for shure testing, it is required to restart the router with the new parameters.
Did everbody know an other method, it will really helpfull in generall ?
This what you are post @xxdanix91xx, makes me fear that it not possible without desoldering the "Filter" on Easybox 803A
It can be happen that Annex J will work but them it will be slow and unstable because it will be miss the down bands, because filter.
This what you say is very interesting and can normally not happen, the only explanetation is:
It does not really working on the speedport W504v too, but i thing you have check it and the datarates are the same as they should be ?
The other theory the opinium that it must be desolder somethings are wrong and it works with an differ config.
I guess something inside the *.dts files. it is possible to replace the kernel only ?
(put the 803A Firmware to the 803A Router and them replace the kernel with the kernel from 504v.
Other explanetations are Voodo and conspiracy.
Can you make a list in which packets the router differ ?
It is a great mistery on lantiq devices why annex-X works on a routermodell-1 and why it does not work on the routermodell-2 with same modemchip with the same firmware in general.
Thank you for your time
I dont't have a speedport w504v. I only used the firmware image of it and flashed it on the easybox. But I will buy one the next days. They cost less than 10€.
Yes, the rates are ok, they are about the same like on my fritzbox.
I will make a list of the packets that differ. I dont't know how I can flash the kernel. But I think the problem is the kernel. What is the difference in modem drivers of the lede image of the easybox 803a and the speedport 504v?
If wifi drivers of the speedport image would work on my easybox then i could use the speedport firmware.
