Puzzling comm / latency issue with Roborio and D-Link over wifi

[jwhite]

We've got an odd behavior that has us puzzled.

We're deploying Java, and everything seems to work.

However, if we look at the log viewer, we see a periodic (about every 8 seconds) drop in communication quality (we get a nice blocky yellow graph). Further, if we start a ping on a terminal, we see 2 ms for most pings, and then about every 8 seconds, we get a ping time of 50 ms.

Again, everything seems to work, but it is puzzling.

And if we wire directly in to either the RoboRio or the D-link with an ethernet cable, the problem vanishes.

Has anyone else seen anything like this?

Cheers,

Jeremy
