411s Video is 5 seconds slow

My video is about 5 seconds slow on my PC when comparing to someone moving or my cellphone.
It is 5 to 8 seconds slow when comparing to www.Time.is, www.time.gov or an atomic watch.
I have the latest software: v7.1.2.40 and 125_16091804.
My camera is connected by cable to a Mi42WR router and then by cable to my PC.
My router is linked to Frontier FiOS (fiber) network.

I tried fluent (unacceptable resolution) and clear. Both were 4 seconds slow vs Time.is

Did anyone notice a delay?

I have no delay on my Samsung S7 edge phone.

Hi, the problem seems that it was on your PC or the router. Here is the suggestion for you:

Change the port on router you used to connect your PC.

Change the cable(suggest to use the CAT6 Ethernet cable) you used for PC to router.

Change a PC to check for it.

Thank you for the response.

I replaced the router to PC cable with CAT6 cable in a different router port.
The 411s video is still 5 to 10 seconds slow vs www.time.gov and the PC time from reolink V7.1.2.40 (upper right hand corner of screen)
My S7 smartphone is also slow (contrary to earlier report)
Reolink memory load is about 58% and CPU load is 27%. Ethernet throughput reads 500-1000 ?units.

I don't have another PC easily available.
My PC is from Puget Custom Computers last upgraded 07/30/2007
It has Intel Core 2 Quad Q6600 Quad-Core 2.4GHz
Kingston 4.00 GB RAM
2TB 5400rpm Hard Drive

I also have this problem where my cell phone shows the video realtime, but the laptop i use, shows a delay of about the same time as you.

Did you ever get this resolved?
