Cisco RV340 high CPU usage when IPS is enabled

Hello, I bought the RV340 router. It has the latest firmware installed. When I turn on the IPS feature, the router is extremely slow and it is impossible to reconfigure it. CPU usage is 100%. When the feature is turned off, the CPU returns to normal and the router becomes available for configuration. IPS was one of the features that led me to choose the product. How to solve it?

Re: Cisco RV340 high CPU usage when IPS is enabled

Try setting the "IPS Security Level" to "Connectivity":

If it was originally set to "Security", you can also try "Balanced".

I have exactly the same problem on mu RV345P!!

CPU 100% when using IPS on RV345P - Unresponsive! 

It seems all RV3xx routers have this problem, but CISCO is not looking for a solution!!
