R6350 router keeps dropping traffic on specific games

It happens whenever I play games like Left 4 Dead and Super Smash Brothers Ultimate. The connection drops for a second, but relaunching the application fixes it. When playing Left 4 Dead, I can't join public games, else i'll get kicked out in around 5 minutes. I went into the logs of my router, and saw this;

Re: R6350 router keeps dropping traffic on specific games

1. What modem are you using? (model number)

2. What firmware is on your router?

3. How are you connect to the router? Wireless/wired.   If its wireless, what wireless adapter are you using and what radio are you using (2.4ghz/5ghz)

4. Are any other games having this issue or just that specific ones?

5. any other devices having this issue?

Re: R6350 router keeps dropping traffic on specific games

1. R6350

2. Auto updates are on, so the latest one

3. Wired. I'm also connected wirelessly on my switch, with the same issue. (5ghz)

4. From what I can see, it's just left 4 dead and Super Smash Brothers Ultimate. Sometimes I get issues with Starcraft 2, but not consistently.

5. Just my Nintendo Switch and my Windows 10 PC.

Spectrum / Charter Communications. I'm not sure which one specifically, but it was provided by them.

This would be the forum for the R6350. not the nighthawk forum.

Really doesn't tell me much. Reason why I ask is some of those units have built in routing function. if it does, it can cause a double nat which can cause issues with gaming.

And a firmware number helps more than "the latest". you'd be surprised at how frequently people aren't "on the latest" or the app doesn't show the latest update. Plus for the people who use this is the future, they have a reference for which firmware you're on.

Re: R6350 router keeps dropping traffic on specific games

I'm only using one router so I'm not sure if double-NAT is a problem. 

The firmware version is V1.1.0.52_1.0.1, and I really don't know what type of modem I have

There should be a label on the back of the modem with a model number.

Re: R6350 router keeps dropping traffic on specific games

Maybe those games need an open nat to function. Not sure as I'm not a gamer.

Changing the default DMZ server to my PC seems to have fixed the issue. Also, the OPEN-NAT thing worked, too. So, yay!
