Lighthouse stops receiving when browsing

When I’m start browsing the files, the receiver stops receiving and indicating ‘NO SERVICE’. This will happen intermittently.The 3rd LED gets start to blink and the service page shows red dot. Also some folders gets empty during this. The receiver back to normal after restating it.

This happened two times.

But now the receiver is operating normally and I can browse without any issue.

My Lighthouse has 1 TB portable HHD attached. Now storage capacity is about 5GB.

Could you open a PuTTY session and watch the top output while you browse?
