Panasonic IP Cam Bl-VT164 unstable connection with Orbi solution sharing

I encounter connection failure with my Panasonic BL-VT164 after using ORBI on almost every 2 days. The short term solution did is simply reconnect the cable but its so annoying. After many trial and error (which I found the service supporting team in Hong Kong is not knowledge enough in my case) , I found the final solution is simply forward the internal port in the advance setting and that is it. now connection is fast and stable. wish everyone enjoy ORBI.
