Model :

Hardware Version : Not Clear

Firmware Version :

ISP :

need help connecting my router to ISP over PPPoE(Broadband) .

Router details:
TP-Link TL-WR841N V10
Firmware version : 3.16.9 Build 150310 Rel.55259n
When I directly plug-in the LAN cable provided by the ISP(Omwebnet) into my windows system and provide username(batcave)/password provided by ISP, connects successfully.

When I connect LAN to router and configure router to connect over PPPoE, throws a CHAP authentication failure (same credentials)

Router Syslog follows(also attached as txt file):

Re:CHAP authentication failure for PPPoE : bad username/password even with right credentials

It should be username and password issue. Contact your ISP to confirm or update username and password.
Reset the router to factory defaults and reconfigure it.
