BSNL Fiber Router resets SSID and Password on restarting!

[cyberswarup]

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

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.

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.

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

You'd need to use cd to change directory. You could go through this link for basic shell commands -- Summary of Basic Commands – The Unix Shell

So try cd /var/config followed by ls to list the contents of that folder.

If you could post screenshots of the results, it would be helpful.

The link to the screenshot in my previous post is broken. Here it is

@ varkey which file to delete?

 

[cyberswarup]

ok I have deleted the syslogd.txt file and restarted the modem. But my problem did not solve, it again revert to the original ssid and password. Should I also delete the files last_good_hs.xml? or delete all the files?

Could you please run df and share the output?

Also, note that the leading / has significance. cd /var/config is different from cd var/config. Anyway since you were already in the /var/config folder it was okay.
