RV340 Internet Speed Reduced

[akwages6178]

I recently installed a RV340 router and have been experiencing the following issue: 

Firmware version is 1.0.03.20, I have all firewall services turned off.  Internet connection is 1Gbps/40Mbps.  

After approximately 10-12 hours Internet speeds are reduced significantly. To 5-6Mbps/10Mbps...

I reboot the router and internet speeds are resolved...

Is there a configuration I am missing?

Looks like somehow Router getting frozen -

2.raise an SMB tac case so they can look for you.
