Netduma R3 Random disconnections

[Chaiyoabc]

I am having problem with R3 on firmware 4.0.290 and latest Early Access firmware 4.0.402 (Early Access). I have no problem with R2 Early Access at all. 

I was playing for about 10-20 minutes and then I was booted out. What should I do to solve this?

What game are you playing? Is it just kicking you from the game or internet also? If you disable the Geo-Filter does it continue to happen?
