my vote is for radio or magnetic interfearance.
if there was an issue with port forwarding you wouldn't see the logical link (11Mbps) drop to 1, this happens onyl* if your wireless nic is getting a (or what it thinks is) a weak signal.
any new neighbors with ham radios?
have you tried changing the channel your router uses from 6 (usually default) to 1 or 11?
54Ghz being at a higher frequency may not be getting enough interfearance to drop its signal strength, maybe just enough to slow down it's transmission because it has to resend a bunch of data that's getting messed with en route...
I have seen this happen in wifi crowded areas if there are one or more ::hidden:: networks.
*...In Real Life this can also be caused by software/hardware issues at the client side.

...on second thought, I would be sure my router/modem firmware and all my device drivers were updated too, just to be sure.
