Hi @vivekagrawal
A blinking LOS light indicates that it is not receiving the optical signal. Given that the ISP tech's modem worked OK the signal is there but your modem doesn't recognize it.
Just verifying that you have you configured the modem by connecting a computer to it using an Ethernet cable to access the modem's menus?
Here's a video (which has a transcript below) that shows what to do.
At 0:50 seconds into the video it shows how to tell if the connection is OK i.e. Wan info > Status = Up or Down
If it is Down, follow the video for how to setup the modem and then check if the status has changed to Up.
If it is Up already, follow the video for how to setup the modem to check that it has been setup correctly.
Did the technician check the settings in your modem to see if they were OK? Very strange if they didn't do this. If they did then the modem is faulty.
As you have already performed a reset, check if there's a firmware update available for your exact model and hardware version, and if there is try updating the firmware and check if that fixes it. If it doesn't then it's a hardware problem which will be difficult to fix as there are no schematics available online or at least none that I could find.

Hello Jayeff,
Thank you for your prompt reply to assist me to resolve my modem issue.
Pls find below the make and model of my modem and other details:
Product Name: SYROTECH G/EPON ONT
Product Model: SY-GPON-1110-WDONT
Power Rating: 12V 1000mA
MAC:3894E0B7DBEA
S/N:SY1811111004863
Further I would like to inform you that when I turn on my modem,the PON light and Wifi light turns on,on the modem & the LOS light starts blinking in red. Moreover on my PC or Smartphone I get the message "No internet connection available". Further,the technician from the ISP had also checked the connection and attached another modem to check if there is any issue with the connection, but the 2nd Modem is getting connected to the internet connection.It is only the 1st modem that is not getting connected.
I hope I was able to answer your query.Pls feel free to ask if you need any other clarification.
I hope you will be able to come up with a solution.
Awaiting your reply.
Thank & Regards
Vivek Agrawal
