When i get FTTH connection, i just connected the ethernet cable from FTTH ONU to existing DSL router TP-LINK TD-W8968 WAN port. Logged in to TP-LINK router management interface at 192.168.1.1, set it to work in “Wireless Router Mode” instead of “ADSL Modem Router Mode”.
Click next, on this page, you need to enter your PPPoE username and password.
You can configure WiFi just like you done for DSL. At this point you will get internet on your PC if you connect to TP-LINK router with LAN cable or WiFi.
Connecting FTTH ONU Directly to Ubuntu
First connect the ethernet cable from FTTH ONU to LAN port on your PC.
Now you need to run
This will scan all network interfaces available on your PC for PPPoE connection.
Once it find a network interface with PPPoE Access, it will ask you permission to modify few files, select Yes.
Next it ask for some options, select Yes
It ask for username and password
One next page, it ask for some DNS setting, select No (or yes, won’t make much diff, i tested both, if required you can always edit /etc/resolv.conf manually, no big deal).
LIMITED MASS PROBLEM – select Yes
DONE – select Yes, this will start net connection by itself.
ESTABLISH A CONNECTION – Select Yes
CONNECTION INITIATED – Select OK, you are done, now you are connected to internet.
To see pppoe log, run
boby@hon-pc-01:~$ sudo plog Jul 30 08:17:14 hon-pc-01 pppd: Using interface ppp0 Jul 30 08:17:14 hon-pc-01 pppd: Connect: ppp0 <--> enx000000003eb7 Jul 30 08:17:14 hon-pc-01 pppd: PAP authentication succeeded Jul 30 08:17:14 hon-pc-01 pppd: peer from calling number 54:1E:56:9A:82:80 authorized Jul 30 08:17:14 hon-pc-01 pppd: local IP address 100.65.237.194 Jul 30 08:17:14 hon-pc-01 pppd: remote IP address 172.31.34.2 boby@hon-pc-01:~$
You can use poff command to disconnect from the internet.
sudo poff dsl-provider
boby@hon-pc-01:~$ sudo poff dsl-provider boby@hon-pc-01:~$ ping yahoo.com ping: unknown host yahoo.com boby@hon-pc-01:~$
You can use
sudo pon dsl-provider
to connect to Internet.
boby@hon-pc-01:~$ sudo pon dsl-provider Plugin rp-pppoe.so loaded. boby@hon-pc-01:~$ ping yahoo.com -c 1 PING yahoo.com (22.214.171.124) 56(84) bytes of data. 64 bytes from ir1.fp.vip.bf1.yahoo.com (126.96.36.199): icmp_seq=1 ttl=39 time=278 ms --- yahoo.com ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 278.963/278.963/278.963/0.000 ms boby@hon-pc-01:~$
When you connect to internet using PPPoE, you will have a new network interface get created, to see more details, run
boby@hon-pc-01:~$ sudo ip addr show ppp0 11: ppp0:

/etc/network/interfaces /etc/ppp/pap-secrets /etc/ppp/peers/dsl-provider
On this file, pppoeconf added following entry
auto dsl-provider iface dsl-provider inet ppp pre-up /bin/ip link set enx000000003eb7 up # line maintained by pppoeconf provider dsl-provider auto enx000000003eb7 iface enx000000003eb7 inet manual
Here enx000000003eb7 is name of my network card, that connect to FTTH ONU.
This is an auto created file. You can delete it if you don’t want to use pppoeconf, it will auto generated when you run pppoeconf.
Here is the content of this file

This file contains username and password. By end of this file, pppoeconf added my username and password in the format.
"my_user_name" * "my_password"
Accessing FTTH ONU Management Interface
I was happy with FTTH ONU connected to TP-LINK router so i can use WiFi. But for some reason i was not able to access the Admin Area of the FTTH ONU.
I tried connecting FTTH ONU directly to my PC using pppoeconf to get access to Admin Area of FTTH ONU Device. The manual come with the device says, i can connect to admin area using IP 192.168.101.8/24
But the local IP i get from ONU was something like 100.65.238.133
I did a scan for IPs available on range 100.65.238.133 using netstat, but it was all other railwire customers, i was able to see some of the modem, even able to login to some of them as they use default username and password for their modems. But for some reason, i can’t access my modem on the IP.
I tried adding a route to 192.168.101.8 using “route add” command, no luck accessing the ONU Admin area so far. For now i reverted the changes, went back to old way of connecting using TP-Link router. Need to find a solution to access the admin area of ONU Device.
