Mining Ravencoin create WAN problems

[Sirdruid01]

Hi, first i describe my rig connection:

The rig is connected by ethernet to a router, and the router connected to my ISP modem also by ethernet.

Problem:
I starting to use NBminer to mine RVN, but as soon as i start the mining, the rig computer's internet stop working, curious thet the miner keeps hashing and sending shares but any page on browser i try to load don't work.

Inmediatly the wan led on the router goes red and any device connected by cable to the router stop working, but wifi still work fine.

Even stopping the mining the problems persist and the only way to return is reseting router to fabric state.

I also tryied connecting the rig directrly to de modem in other port, but the problem is the same, all cable connectios even in the router stop working
