Radio wifi packet loss

Hoping someone can help us with our radio. We have our roboRIO hooked up to a OM5P-AN. We get a lot of packet loss when we are connected via wifi, significant enough to interfere with manual motor control (i.e. motors will stop turning for a second or more).

We don't experience loss when the driver station laptop is plugged into the roboRIO via ethernet or USB nor does it happen when the driver station laptop is connected to the radio via ethernet.

After checking the battery and wiring to make sure everything was well-connected and powered, we tried the following with no effect:
- swapped out the radio with a different OM5P-AN
- swapped out the roboRIO
- re-imaged the roboRIO
- reconfigured the radio with the Radio Configuration Utilitiy (16.2)
- checked wifi channels to ensure there was no interference

At one point, we swapped out the OM5P-AN with a D-Link which we reconfigured with the Radio Configuration Utility. The D-Link had much less loss although there was a little. Swapping the OM5P-AN back in produced the same loss as it originally did.

Any thoughts? The driver station laptop is running Windows 7.
