TP-Link TD-W8970B internet not working (LEDE v17.01.1)

trismo · April 24, 2017, 4:20am

German use:

ADSL2(+) ATM & VDSL2 use PTM
Near all german provider use VLAN for easybell ist allways VLAN vid 7

I have this device to but never used it with adsl

config atm-bridge 'atm'
        option vpi '1'
        option vci '32'
        option encaps 'llc'
        option payload 'bridged

config dsl 'dsl'
        option annex 'b'
        option xfer_mode 'atm'
        option line_mode 'adsl'

config interface 'wan'
        option ifname 'nas0.7' 
        option proto 'pppoe'
        option ipv6 'auto'
        option username 'XXX'                  
        option password 'XXX'

I dont now if this wan ifname "nas0.7" is supported this way its not working try nas0

Thank you very much for your reply!

I changed my configuration file, now it looks like this:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config dsl 'dsl'
        option firmware '/lib/firmware/lantiq-vrx200-b.bin'
        option xfer_mode 'atm'
        option line_mode 'adsl'
        option annex 'b'

config interface 'lan'
        option type 'bridge'
        option ifname 'eth0.1'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'ptm0'
        option proto 'pppoe'
        option ipv6 'auto'
        option username 'XXX'
        option password 'XXX'

config device 'wan_dev'
        option name 'ptm0'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'
                            
config switch_vlan
        option device 'switch0'                
        option vlan '1'                        
        option ports '0 2 4 5 6t'   
                             
config atm-bridge              
#       option unit '0'       
#       option atmdev '0'        
        option encaps 'llc'  
        option payload 'bridged'
        option vci '32'       
        option vpi '1'

Renaming to "nas0.7" or "nas.0" did not work, ifconfig did not show any interface anymore.

I'm afraid this did not help, the internet connection still is not working. The error message is still the same as before.

What does it mean that easybell uses VLAN 7? How can i configure my router to use VLAN 7?

trismo · April 25, 2017, 7:50am

Virtual Local Area Network (VLAN)
To make it easy to describe, it is to put one real network to divide into several virtual ones.
Internet pppoe work over VLAN id 7
Here a German weblink easybell

You get even a ADSL sync ?
Use option firmware only you put manual a firmware binary to /lib/firmware

config dsl 'dsl'
option xfer_mode 'atm'
option line_mode 'adsl'
option annex 'b' # this option setup the firmware for you

config interface 'wan'
option ifname 'nas0'
option proto 'pppoe'
option username 'XXX'
option password 'XXX'

config atm-bridge
option encaps 'llc'
option payload 'bridged'
option vci '32'
option vpi '1'

give me please output with this config after reboot ~ 3 min.

The internet is working now, thank you very much!

I think the problem was the firmware I configured. I read the tutorial from OpenWRT, which was a little misleading. That is why I added the line

option firmware '/lib/firmware/lantiq-vrx200-b.bin'

to the config file. Without this line, it works!

trismo · April 26, 2017, 8:51pm

Good

fbradyirl · July 12, 2017, 8:22am

Hi guys, I have a very similar issue to the original poster. Wonder if you can help.

My ISP: Eir (Ireland)
My Router: Linksys E4200v2
Current Firmware: LEDE 17.01.0-rc2
Type of Internet: Fibre to The Home
Settings: From here

To connect your third party router to Eircom, you will need to apply the following settings.
Encapsulation PPPoE
Multiplexing	LLC
VPI	8
VCI	35
User name	eircom@eircom.net   (eir@eir.ie will also work)
Password	broadband1
VLAN tagging	Enabled
VLAN ID	10

Now, I have been trying various different methods to get this router to connect over PPPoE but fail each time.

	option ifname 'eth1.10'
	option username 'eircom@eircom.net'

	option ipv6 'auto'

I am thinking, based on this thread, that my wan interface is wrong. I have it set to use option ifname 'eth1' because I know that the E4200v2 router uses eth1 for the physical wan port. But maybe that needs to point to a virtual VLAN? Eir state that the WAN needs to be set to VLAN 10 to get traffic.

Note that I also tried this config but get the same result and the same failed discovery in the logs:

config atm-bridge
	option unit '0'
	option vpi '8'
	option vci '35'

config interface 'wan'
	option proto 'pppoe'
	option pppd_options 'debug'

fbradyirl · July 12, 2017, 8:59am

Actually it would seem my router just doesn't have a modem. Please ignore me

eduperez · July 12, 2017, 9:00am

Those instructions you linked are for a DSL connection; you mention you have a FTTH connection, and your router does not support DSL. You need to find out how to configure your router for the FTTH connection from that ISP; I could not find any relevant info in their website, perhaps you should contact them, or ask in their user forums.

fbradyirl · July 12, 2017, 10:38am

I am wondering if I need PPPoE at all? When I log into the Eir supplied router it simply says that it is connected by "IP Routing". So I image it is just a DHCP client to the device on the wall.

The yellow ethernet cable in the image is plugged into the WAN port of the Eir supplied F2000 router.

eduperez · July 12, 2017, 1:00pm

You definitively have a FFTH connection, and that box on the left is the ONT.

Now, to configure your LEDE router you might need to use VLAN and / or PPPoE, it depends completely on how did your ISP decide to configure their end of the connection. I will start trying to use PPPoE with the same parameters and no VLAN:

config interface 'wan'
	option proto 'pppoe'
	option pppd_options 'debug'
	option username 'eir@eir.ie'
	option password 'broadband1'
	option ifname 'eth1'
	option ipv6 'auto'
	option keepalive '5 20'

If that fails, you can try to use VLAN 10:

config switch_vlan
	option device 'switch0'
	option vlan '10'
	option ports '4t 6t'

config interface 'wan'
	option proto 'pppoe'
	option pppd_options 'debug'
	option username 'eir@eir.ie'
	option password 'broadband1'
	option ifname 'eth1.10'
	option ipv6 'auto'
	option keepalive '5 20'

But all of this is just "shooting in the dark"...

fbradyirl · July 12, 2017, 1:49pm

Thanks so much for your help @eduperez

Yes, VLAN 10 is definitely a requirement. Eir recommend it on forums such as this one where the support person recommends:

Set encapsulation to IPoE, and set the VLAN (802.1q) tag to 10, leave 802.1p to 0 I do believe that should do the job.

Thank you for the settings you recommended, however is there any chance they will work since you mentioned my Linksys E4200v2 might not support it? Does my LEDE router require a VDSL modem perhaps?

Is IPoE just a fancy name for a DHCP client??

fbradyirl · July 12, 2017, 1:49pm

I am at work so I will try that config when I get home later....

eduperez · July 12, 2017, 2:41pm

Both VDSL and ADSL refer to the old telephone lines (cooper pair), and have nothing to do with the fibre line you have installed. As far as I know, you already have all the hardware you need, and your device should be perfectly capable of establishing a network connection. Your ISP is making things very confusing for everybody, because they call "Eir Fibre" both to FFTC and FFTH, hence the documents talking about fibre configuration with VDSL lines.

I could not find any document, or blob or forum post, indicating how to configure your FTTH line... perhaps you could have a look at the configuration pages in the device provided by the ISP, if those are accessible to you.

fbradyirl · July 12, 2017, 3:06pm

I agree. They don't make it simple!

Here are the settings on my ISP router:

When I press Save you can see this (I have removed partially the IP addresses):

eduperez · July 13, 2017, 6:36am

I do not see any info about PPPoE in these settings; it is quite uncommon, but perhaps your ISP made things very simple, and you just need a DHCP client. Please try this, and report back:

config switch_vlan
	option device 'switch0'
	option vlan '10'
	option ports '4t 6t'

config interface 'wan'
	option proto 'dhcp'
	option ifname 'eth1.10'

fbradyirl · July 13, 2017, 7:09am

Oh my g*d yes! That worked. Thank you so much! I had it bridged last night to my e4200, but now I can get rid of that other router. Thank you again!

fbradyirl · July 13, 2017, 9:34am

Out of interest, can you explain how you decided on the numbers 4 & 6 in the switch_vlan section? '4t 6t'

eduperez · July 13, 2017, 11:26am

I did not decide to use those numbers, it was you ;)! In the first comment you posted in this thread, your config had a VLAN entry for eth0 that comprises ports 0, 1, 2, 3, and 5, and a VLAN entry for eth1 that comprises ports 4 and 6.

I guess (and I could not find any documentation to support this) that ports 0, 1, 2, 3 correspond to the LAN ports, port 4 is the WAN port, port 5 is the eth0 interface, and port 6 is the eth1 interface. I just added the "t" after each port number on the WAN part, so we send and receive tagged packets on the outside (per your ISP decision) and keep them tagged on the inside (thus we configure the WAN interface as "eth1.10").

Speaking of this... if your ISP only provides internet access on that connection (some providers use the same fibre for internet + VoIP + IPTV), you only need an external interface, and could possible simplify your configuration to this:

config switch_vlan
	option device 'switch0'
	option vlan '10'
	option ports '4t 6'

config interface 'wan'
	option proto 'dhcp'
	option ifname 'eth1'

fbradyirl · July 13, 2017, 12:37pm

Ah OK yes I think you are exactly right about the port and interface numbering.

I will play around with removing the t from the port 6 config as you suggest later. Thank you again.

jnachtigall · October 7, 2017, 9:47am

Hey @3R1K, I don't want to hijack this old thread, so I opened another thread here. I am severly struggling just to install LEDE on a TP-Link W8970B (after being able to telnet into the old firmware), how did you get that working? Would be great if you or someone else could have a quick look and maybe give pointers.
