Problem with play desktop internet - Technicolor CGA2121 modem

A month ago I bought fixed internet from Play, the installer installed and configured everything and for a month everything worked flawlessly.
Today I unplugged the modem from the power for a few hours and after plugging it back in the power LED lights up for a few seconds and then flashes every second or so. It is possible to connect to the modem but there is no Internet all the time. (Earlier I also disconnected it from the power and after connecting it back after a few minutes the LED stopped flashing and the Internet started working)
Reset the modem several times, reconfigured unfortunately the problem persists
I would appreciate help if anyone knows how to solve this problem .

Is the coaxial cable connected to the modem?

Yes, I've also already taken it out and put it back in. I also noticed that the power LED flashes also when the coaxial cable is disconnected.

Can you log on to its website and look for DOCSIS signal parameters in the options?

The modem did not detect any DOCSIS signal (although supposedly 1 downstream channel detected and there should be these channels from 16 to 24, and did not detect any upstream channel and there should be these channels from 4 to 6) and therefore did not log in to the operator's network and did not download provisioning from CMTS - there may be several reasons for this and none of them are under your control:
- defective modem,
- defective power supply from the modem,
- some network/network failure on the operator's side.
You won't verify it yourself - call the operator and report it.

Ok thanks for your help, I will go to the play point today and see what they say

Points are in the business of selling services, not service or taking calls - this is verified by the operator, after the customer reports it to the operator on the hotline.
The store won't check the modem, because they probably don't even have a cable network there with PLAY's DOCSIS signal, they won't verify a modem without a signal, and whether something banged on the line at the customer's place of residence they won't verify either, because it could be a local problem at the customer's place of residence.

I called and they actually have some kind of breakdown in my area, thanks for your help

Then you wait patiently until they fix it.

For as many days when it did not work, you can make a written complaint and demand in it a reduction in the subscription for as many days as it did not work, in addition, you can demand compensation.
Compensation and reimbursement of the subscription for all the time when it did not work, we calculate like this - you divide the subscription by the number of days in the month, a number comes out and this you multiply times the number of days when it did not work.
