Connection is very inconsistent (RBR40)

[ransomeb94]

I recently got my parents  to the get the RBR40 because they were having a lot of connection issues with our  old router. We got the RBR40 and it works fine except for me. I play games and stream on twitch. Whenever I play online games, I find  that I lose a lot of packets every 15 seconds just about and I'm not sure why.  My streaming software also goes to 0 in bitrate and then goes back up, but will go back to 0 between 15 to 20 seconds and its very annoying. Any fix?
