Question / Help Dropping frames...I've found my problem, but, what's the solution?

Hi guys.
I realize now this may be a better question for a networking site. I still have a couple more troubleshooting steps to go through myself.

Anyway, I started streaming on Twitch and I also tried YouTube. Was using an Elgato Game Capture HD to my PC. PC is wired.
With both platforms, I was seeing a frame drop. Not major (on YouTube), but, enough to produce some stutter.

Played with settings on my PC (in OBS); no change
Speedtest looked fine (100+ Mbps down and 17-20 Mbps up). Tried different servers and the issue still persisted. Didn't see any packet shaping issues with my ISP.

Today, I finally decided to play around with hardware...and I figured out my problem.

My setup is this:

ISP > Cable Modem > TrendNet TEW-692GR router > TrendNet TEG-S80G (unmanaged switch)
My consoles are plugged into the three ports on the router (Wii U, Xbox One, PS3)
My computers and printer are in the 8-port switch (including the PC I used for streaming)

When I plugged the streaming PC and the Wii U together in the router ports = NO FRAME DROPS!
I tried Wii U in the switch and PC in router = FRAME DROPS
I tried both PC and Wii U in switch = FRAME DROPS

So...I'm dropping frames between my switch and my router.
All equipment is gigabit (though the Wii U only does 10/100).

My question: Is there a setting on my router I should check/test to see if I can eliminate the dropped frames? There's basically nothing I can do with the switch, as it's unmanaged. There's no uplink port, as it's auto-sensing. I tried a few ports and it didn't make a difference.

The other test I'm going to try is to find another gigabit switch and sub it in for my current switch to see if the switch hardware is the problem. Won't be able to test that until tonight.

Thanks for any help. I wanted to be thorough because this may help someone else with the issue out there.

Should also note I never have much traffic going on when I'm streaming. And, I don't think there would be any other traffic going to the switch at night when I'm streaming, either.

try open command and do: ping -t 192.168.0.1 (ctrl+c to stop, change address depending on router or other devices)

Dropped ping? If yes, the problem is anywhere between your computer and the router/device. Might be bad cable or switch.

I had done a large sessions of pings within my network and never had any drop.

But, my original switch is definitely the culprit. I brought a switch home from work, and streamed for nearly two hours with no frame drops! Put the old one back in place, and frames started dropping immediately.

Off to buy a new switch!
