German Vodafone Fritz!Box 7430 adsl2+ config

fritz · April 29, 2023, 8:24am

I have successfully flashed an old Fritz!Box 7430 with OpenWRT. Now I need to figure out how to make it work with my DSL line. ISP is Vodafone and the EasyBox 804 shows the following:

I have the username and password from the Vodafone website.

The relevant parts of the config are as follows:

/etc/config/network

config dsl 'dsl'          
        option annex 'b'                  
        option tone 'av'

config device                             
        option name 'dsl0'                
        option macaddr 'xxxxxxxxxxxxxx'
                                          
config interface 'wan'                    
        option device 'dsl0'              
        option proto 'pppoe'              
        option username 'xxxxxxxxxxxx'
        option password 'xxxxxxxxxxxx'
        option ipv6 '1'                             
                                                    
config interface 'wan6'                             
        option device '@wan'                        
        option proto 'dhcpv6'

Maybe someone can give me a hint on what to try to make it work.

A quick search reveals this user who posted how they got their internet working with Vodafone Germany. Hopefully it can be of some help to you.

fritz · April 29, 2023, 9:24am

Thanks for the pointer, still not working.

I have changed my config to

I think it maybe a driver issue

Thanks for the help but it is not working. I have tried a couple of variants of the config. The last one is here:

/etc/config/network

There is no wan device in ifconfig. I am starting to wonder if this is a driver issue because ifstatus wan shows that there is no device.

I am having a hard time troubleshooting this because OpenWRT is quite different from desktop linux distros.

d687r02j8g · April 29, 2023, 5:56pm

Apologies, could we clarify your setup please

You have an openwrt device Fritz!Box 7430

You have a separate device, EasyBox 804. This is provided by your ISP.

Do you want to have the Fritz!Box 7430 do all the work and remove the EasyBox 804 out of the equation?

fritz · April 29, 2023, 6:00pm

Exactly. Currently I am using the EasyBox but I want to switch over to only use the Fritz!Box.

d687r02j8g · April 29, 2023, 7:32pm

Can you provide the output of

logread

And also the kernel log

dmesg

Perhaps there are clues here why the dsl device isn't working.

janh · April 29, 2023, 7:41pm

You probably need an Annex B DSL firmware.

If you remove the firmware option from your config, the pre-installed Annex B firmware should automatically be used.

Alternatively, you may try a more recent firmware, which you would need to copy to the device yourself. Here is a list of known versions. If you don't know which one to pick, the one used by AVM in the original firmware is probably a good pick (5.9.1.4.0.7-5.9.0.D.0.2).

Knogle · April 29, 2023, 8:41pm

Hey mate, how are you doing?
Did you try sniffing on the DSL interface, using tcpdump? I think it would be really useful. Maybe you can save it as pcap file, using something like that: tcpdump -i dsl -w dsl.pcap

fritz · May 1, 2023, 8:38am

Ok, thanks! I have downloaded the image and unpacked the firmware.

I am on Manjaro and bdiff is not in the repo any more. I have compiled it myself and it doesn't work

Summary

$ ../../../../../bsdiff/bspatch vr9-B-dsl.bin vr9-A-dsl.bin vr9-A-dsl.bin.bsdiff 
bspatch: Corrupt patch

I am not sure which of the files is the correct one, I have tried vr9-B-dsl.bin.

Summary

config dsl 'dsl'
        option annex 'j'
        option tone 'bv'
        option fwannex 'b'
        option firmware '/lib/firmware/vr9-B-dsl.bin'

and I still get the NO_DEVICE error

Summary

	"up": false,
	"pending": false,
	"available": false,
	"autostart": true,
	"dynamic": false,

No, I haven't, how would I do this?

There has been a development:

I have copied all the firmware to the /lib/firmware/ and I have used bspatch on the router to create release-vr9-B-dsl.bin and it worked. Now the NO_DEVICE error is gone:

Summary

root@OpenWrt:~# ifstatus wan
{
	"up": false,
	"pending": false,
	"available": true,
	"autostart": true,
	"dynamic": false,
	"proto": "pppoe",
	"device": "dsl0.7",
	"data": {
		
	}
}

EDIT: specify the exact firmware file
EDIT2:

DSL control stat now switches between "silent", "handshake", "exception"

Summary

root@OpenWrt:~# service dsl_control dslstat | grep state
	"state": "Exception",
	"state_num": 1,
	"power_state": "L3 - No power",
	"power_state_num": 3,
root@OpenWrt:~# service dsl_control dslstat | grep state
	"state": "Handshake",
	"state_num": 4,
	"power_state": "L3 - No power",
	"power_state_num": 3,
root@OpenWrt:~# service dsl_control dslstat | grep state
	"state": "Silent",
	"state_num": 3,
	"power_state": "L3 - No power",
	"power_state_num": 3,

EDIT3:
I have reverted the config back to the one here and I got a connection.

Summary

root@OpenWrt:~# service dsl_control dslstat | grep state
	"state": "Showtime with TC-Layer sync",
	"state_num": 7,
	"power_state": "L0 - Synchronized",
	"power_state_num": 0,

it successfully resolves urls but then ping doesn't work:

Summary

Maybe try:

(self extracted firmware blob of FB7490 7.28, which worked for vdsl2 for a long time for me, in Germany)
