BSNL Fiber Router resets SSID and Password on restarting!

cyberswarup · Jan 18, 2020

I have taken a new BSNL ftth 777 plan, and they have provided a "Sharp Vision" modem with default SSID and password for wifi. Everything is working fine including speed. Now I have changed the SSID and password to my liking. Whenever I restart the modem, the SSID and password reset automatically to the earlier one provided by BSNL. This is frustrating as I have to change again after every restart. Any solution please? thanks

Could you please post a picture of the modem? Please add a pic of the underside of the modem as well.

@cyberswarup , is there any username that you login with?

Could you try changing something unimportant... For eg WiFi channel no from say 6 to 1. And maybe dns to 8.8.8.8 and check if it sticks after a restart...

And have you taken the connection directly from bsnl, or via an LCO (local cable operator)?

@ eriek_halenx first username is the one at PPoE setting, second is modem login 'admin', third is SSID which resets on restart.

I have taken the connection from LCO

Wow, the same ONT is rebranded in different names, Syrotech, Netlink and now Sharp? 😅😅

And I know why the settings doesn't stick. Did you by any chance enable logging in the web UI? If you enable logging, it will use up the disk space on the device and when you make changes there won't be space to write to disk.

You'd need to telnet/ssh in and delete the log file, disable logging from UI. After that your changes should stick.

@varkey
I wonder what this forum would have been without good guys like you giving all the valuable info. 😊👍

Ok thanks. Please tell me the procedure to telnet/ssh in and to delete the log file.

I don't have that device running now so can't give the exact steps, but it's basically telneting into the ONT/modem IP address. You should be able to login with the admin creds. Although the password might be stdONU101.

After that if you type sh you should get access to the shell. Maybe navigate to /var/log or /var/config (I don't remember the path fully) and you should see the log file. Just do rm <file name>

Ok thanks. I'll try out. BTW I have done factory reset but that did not help.

varkey · Jan 20, 2020

Yeah if its a disk full issue, I don't think it would delete the files on factory reset. You'd need to telnet in and verify.

After entering shell, when I typed var/log or var/config, it says permission denied
