When I dial up my BSNL FTTH connection from my pc using username and password, it connects within few seconds, but when I try doing the same from my router (so that more people can connect to my router), I am not able to do so, it fails to connect everytime with an error "Timed out waiting for PADS", but sometimes router successfully connects in PPPoE mode.. like 1 in 100 times. But the remaining 99 times I get the error. When dialling via PC, I never got an error yet and have connected within few seconds.
I tried also cloning MAC address of my PC into the router but it didnt work. Also, if my router by chance gets a successful connection established, it loses the connection on router restart and then again throws in the error.
Can somebody help me with this please ?
Router : TP Link Archer C50 v4
Modem : Nokia Siemens H640V-25E
