My previous post was badly worded. All your copies of OmniFocus, not just the one on the Mac, are going to need to restart when the wireless network changes.

In general, if you quit all running copies of OmniFocus before switching from one wireless network to another, you should be able to sync. Alternatively, you can do a device-to-device connection and sync that way.

If, after doing that, you're still only able to sync on one of the two wireless networks at your house, you'll want to investigate the configuration of thos networks to see if they're blocking OmniFocus somehow.

My home wireless network configuration prevents Apple's "Remote" application from working, but that's not a bug in the Remote app - it's a network configuration issue.
