NetGear's PTV300 Miracast adapter has been available for some time now, but it just recently received a firmware update that made it compatible with a number of Android devices. Now at v2.2.9, which is the third official firmware update (Android functionality was added in 2.2.7), supported devices now include:

Samsung Galaxy S3 (Android 4.1.1 or above)

Samsung Galaxy Note II

Samsung Galaxy Note 10.1

LG Optimus G (Android 4.0.4 or above)

Google Nexus 4 (Android 4.2.1)

Sony Xperia (various models with Android 4.0.4 or above)

Miracast remains a fairly new standard, so some hiccups may still arise. Lakeeast in our Nexus 4 forums says the recent Android 4.2.2 update might have affected things, but we've yet to confirm this. (Still trying to our PTV3000 updated from a the last firmware update.) If you've got one, give it a shot. And if you're still on the fence, keep an eye out to see what's what.

We've got the full v2.2.9 changelog after the break.
