AC-68U w/ AC-87U media bridge unstable on AC. 2.4 works great

[rxallan]

I'm having an issue with my setup. The 87 is my primary router and the 68 is setup in bridge mode.

When bridged in AC my ping to a game server jumps to to like 900ms. When bridged in 2.4 my ping stays around 80ms (PC cat5'd to the 68). From my PC, I can also use a USB adapter to connect to the 87 (the USB ac56u) on both AC and 2.4 without issues.

It's just the bridge in AC giving me issues. Im on the latest firmware for both routers.

Any ideas?

Where are you pinging from? Behind the 68? It might be a good idea to try ping from directly behind the 87 as well, just to see where exactly this crazy near-1 second ping timing is coming from. 87, as you probably know, has always had 5GHz issues cropping up.
