Maybe the wireless keyboard itself?

I finally dug out a USB keyboard and poof lag gone. Changed the batteries, same thing. I have two of the same wireless keyboard so tried the other one, same thing.

Dig out an old ASUS USB BT-400 adapter, disable the onboard BT, plugin in the dongle, repair, zero lag.

Thanks Gigabyte... Though I wonder, I'm not using the onboard Wifi, but does the antenna that comes with it also work as a BT antenna since the BT chip would be on the motherboard?

I have a Gigabyte mobo and the antenna is for wifi and bluetooth. I don't have lag but my Xbox controller will disconnect sometimes.
