Dear Sir/Madam,
I recently updated my modem Firmware to Version TD-W8968_V2_140514 but after this update my Modem stopped updating Time from the Time Servers that i provided Which were Global Server.
I tried both IP addresses and Domain Names of Time Servers but nothing happen.Kindly advise me as Every other setting from Parental Control to Wireless Schedule to Some firewall rules depend on the Time. :confused:
Below i mention few Time Server that i tried:-
1.asia.pool.ntp.org
2.in.pool.ntp.org
129.6.15.30
etc.
(I am using PPPoE with auto dial)
