Lose internet connectivity when using PPPoE and Vigor 120 #50

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. ADSL resync on Vigor 120
2.
3.

What is the expected output? What do you see instead?
Expect 2130 to reconnect to ISP. Instead router loses internet connectivity 
although online statistics still show a connection.

What version of the product are you using? On what operating system?
Vigor 2130 Firmware 1.5.1 and 1.5.2RC Win7 

Please provide any additional information below.
Have tried disabling hadware NAT, port energy saving etc. Router still loses 
internet connectivity on modem resync (have had to re-instate a 2910 to keep 
connection up).  Dial PPoE button inoperative in hung state although local 
routing works OK.  Router warm reboot solves problem.

I report this on Issue 49, you change WAN you lose DNS.  paul.bij...@gmail.com 
try ping with IP and host name, you have connection but you can't use name.

When disconnect.
please check the routing table by "route" command.
and also check the ppp interface by "ifconfig ppp0"

Don't reboot the router, you can do "ifup wan"
capture the log and upload here by "logread"

We need more information for this issue.

Please see attached file for info requested.

Router still required a reboot to reconnect to ISP.

Have done "route" and "ifconfig ppp0" before and after "ifup wan" for 
completeness.

The route and ifconfig result looks fine when disconnected.

The reconnect fail reason is shown in the log:
Sep 30 15:04:27 Vigor2130 local4.err pppd[1028]: unrecognized option 'nic-ppp0'
Can you try to reboot the vigor 120 ?

I also want to check your config file by "cat /etc/config/network"

refer to
https://dev.openwrt.org/ticket/2439

It seems you have wrong config in your wan ifname
It should be eth1.2 instead of ppp0

root@Vigor2130:~# cat /etc/config/network
config interface loopback
        option ifname   lo
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0

config interface lan
        option ifname 'eth0.1'
        option proto static
        option ipaddr    '172.17.3.6'
        option netmask   '255.255.255.0'
        option detect    0
        option type      'bridge'
        option pppoe_pass 0

config interface wan
        option ifname eth1.2
        option proto pppoe
        option disable   0
        option unit      0

Checked online stats after disconnect again.
Disconnects happen after dynamic IP address change.
Router is logging into ISP but is not renewing external WAN IP address.  Satus 
shows as connected but with old IP address.
Drop/Dial PPPoE drops connection but will not redial.
ifup wan has same effect.
Logread and cofig etc. as before.
