Using my wired PC to the router, when I try to ping a client connected on the 5GHz network I get spikes and significant packet loss.

This goes on and on.
I get the same type of spikes if I use the Network Tools in the ASUS GUI to ping the wireless client.
When I ping the wired PC from the wireless client I get constant latency between 1ms - 3ms, with rare spikes to 1000ms or more, and very little time outs.
When I connect the wireless client to the 2.4GHz frequency on the router, I no longer get this issue.
5GHz settings: N + AC Only Channel Bandwith set to 20 / 40 / 80MHz Channel 161
My throughput between the wired PC and the wireless PC averages around 160Mbps (20MB/s). I find that accessing shared folders from one PC to the other can lag quite a bit before the folder is opened, which I would assume is because of what is causing the lag spikes.
There are no other 5GHz networks in the area as per inSSIDer. No microwaves, or cordless phones in use. I have tried to disable the software firewall on my clients to see if that is the issue, but the spikes remain. (Plus I do not think the firewall can distinguish the difference between a 2.4GHz wifi connection and a 5GHz connection).
Has anyone experienced anything like this? If so, I would appreciate your input.
When I return home I plan to try the following:
- Move router to another location to see if my DSL modem could be interefing with the 5GHz frequency (shot in the dark, since wireless is disabled on the modem and it is set to bridge mode only). - Try another 5GHz Channel - Change the driver for the adapter on the wireless client - Try another firmware if the above fails
Anything else I should try?

I ended up changing the wireless adapter drivers to an older version. For some reason, the 5GHz antennae stopped working. I reverted back to the most current driver, and the ping spikes have stopped.
