Hi,
i have EG915UEUABR03A01M08

ppp config:
refuse-chap refuse-mschap refuse-mschap-v2

Log:
using channel 14
Using interface ppp0
Connect: ppp0 ↔ /dev/ttyUSB7

rcvd [LCP TermReq id=0x3 “Authentication failed”]

Connection terminated.

the server is configured to be authenticated in PAP, why do I have PAP AuthNak id=0x1 “Login ok” as incorrect information and the connection closes?
Thanks

Hi ，
This is caused by incorrect account or password, or incorrect symbol format.
It is likely that there is a problem with the logic of your server authentication, and you should not reply with ‘login OK’

Hi,
trying the same credentials and the same sim with the EG912Y modem works, we replaced it with EG915U and we found the problem, the firmware is version EG915UEUABR03A01M08_01.212.01.212. We are trying to update to 216 to see if it solves the problem
Thank you

Hi,
after updating the firmware to version EG915UEUABR03A01M08_01.216.01.216 the modem EG915U works correctly with PAP authentication, I only had to leave the “refuse-chap refuse-mschap refuse-mschap-v2” instructions for PPP
