[SOLVED] TP-Link W8980 VDSL Modem

Hardware Questions and Recommendations
1

Hi,
I got a WR8980 and used it with a ADSL connection with no problems . Some weeks ago I swtiched to VDSL and I coudn't get it to work. I'm not sure if the modem supports VDSL with vectoring (aka G.993.5) (I tried it with a vectoring firmware from https://xdarklight.github.io/lantiq-xdsl-firmware-info/)

Maybe somebody could explain to me what the modem is capable of and how it is affected by the firmware.

Or maybe something with my configuration ist wrong? (I'm not even getting a sync) (it is a Deutsche Telekom connection resold by 1UND1)

Cheers,
Johannes

It is describe in the datasheet of the VRX268 chipset VRX288 or VRX268 is the mainchip + VRX208 DSL-modemchip = called VRX200, xrx200 or vr9


Vectoring will not listed here, but the most VDSL solution are based on this chipset and the most of them support vectoring, like FritzBox 7360

https://avm.de/produkte/fritzbox/fritzbox-7360/technische-daten/
https://wiki.openwrt.org/doc/hardware/soc/soc.lantiq
So vectoring seems like a software problem only.

How the bpatch of the firmware are working and the meaning of the option parameter annex and firmware can be see here:

cat /etc/init.d/dsl_control

The meaning is:
If you use an extra Firmware use option firmware '/path-to-firmware'
for example my config are:

config dsl 'dsl'
        option annex 'b'
        option tone 'av'
        option xfer_mode 'ptm'
        option line_mode 'vdsl'
        option firmware '/lib/firmware/FB7360.111.06.30/dsp_vr9/vr9-B-dsl.bin'

I am not shure, but only firmware or annex and xfer_mode are important for vdsl.

Thank you for your reply. For some reason it "just worked" this time :wink: I extracted the firmware out of an image of a Fritzbox 7490. Maybe it is a problem that I put it in /tmp last time? But I cannot eliminate the possibility that I used an annex A firmware by accident ... not 100% sure
