We use the available sensor system on our network hardware. We have a wifi antenna cut regularly. we want to know why after each cut the graph resumes where it was stopped and sometimes it gets to zero. Do it drevrait not start from scratch each time?

What may be happening here is that during the times when the sensor cannot read the uptime, the PRTG cannot make a connection to the device to read the uptime but the device is still up which is why it will resume where it left off when the values were last read. In the other cases, the antenna shut down or restarted which resets the value to 0 for the uptime.
This information is not controlled by PRTG but only read from the device. If the device reports a certain value for it's uptime, that is what PRTG will report. In this case it seems like the device thinks it is still up or the counter is still counting time even though PRTG cannot read the value. This is something that you would need to examine on the device or ask the manufacturer about if this is unwanted behavior.
