[Nexus 4 Accessories] Levistras:
What I've noticed with my Nexus 4 (running stock 4.2.2, rooted & unlocked) with PTV3000 running 2.2.9.

-Will not connect if connected to wifi on 5ghz at the same time. If connected to 2.4ghz wifi, PTV3000 connects no prob (sometimes 1-2 retries needed, but it works).

-While connected, performance is poor. (Audio stutters fairly often (every 10-20 seconds), Video stutters every minute or two (h264 blockiness, frame loss etc).

-If you're more than 6 feet away from the PTV3000, even if you still have line-of-sight, performance degrades to a point where it's not even worth trying.

-Is the only device I've heard of thus far that will let you stay connected to WiFi (albeit only on 2.4ghz at the moment) while you're connected to the PTV3000.

***Verdict: Passable for listening to music.. almost. Waiting for a fix from either Google or Netgear.

On a Note 2:

-Won't connect to PTV3000. The Note 2 accepts the connection, but the PTV3000 keeps trying and then fails due to "HDCP Error". (I've had similar issues with MHL on Note 2 with my setup... although I'm connecting to HDCP capable components.

***Verdict: Can't test?... I blame Samsung.

On an Optimus G:

-Connects 9.5 out of 10 times, usually pretty quickly as well.

-Audio is flawless

-Video never has frame losses per se, but stutters and shows low frame rate during full screen video (downloaded videos, youtube etc).

***Verdict: I use it all the time for audio streaming, though there is some loss in quality, it meets my needs when I just want to hear a quick tune, or relay some audio from youtube, or play an audiobook. Video playback is passable if I want to quickly show my wife or somebody who is over something on Youtube... but if you're going to be watching Netflix, or downloaded TV/Movies, you're going to want to use another device (Laptop, PS3, etc), or plug in an HDMI/MHL cable.

Overall: Miracast is kinda cool.. but everybody seems to have a slightly different implementation, and right now it's breaking the performance enough for it not be usable on a regular basis. That said.. I am hoping alot of these issues are adherence to standard on the smartphone side, and will improve over time with upcoming devices.. though I hope the PTV3000 has enough horsepower to keep up with changes to the standard as it evolves. It is not surprising that LG, having had the most experience with Miracast thus far (on their TVs) have the best implementation at the moment on their Smartphones. (Though I haven't yet tried a Sony phone).

(For those curious, the TV I'm connecting to is a Sharp LC42D64U, the audio is passed through optical toslink to my LG 5.1 surround system, all components are about 5 years old.)

If anybody is interested... here's the transcript of a not-so-helpful interaction with Netgear chat support:

Levistras

I recently purchased a PTV3000 and updated it to 2.2.9. I"m connecting with my Nexus 4 running stock 4.2.2 firmware. Connecting is not my issue, but once connected, audio stutters every 20 seconds or so, and video is prone to frequent frame drops and stuttering as well.

However.. when I connect with my Optimus G, things are 500% better. Audio never chops, and video only sees some frame rate drops when viewing video.. but is overall much more watchable.

1:49 am I'm curious if you are aware of issues with Nexus 4, and perhaps have any suggestions.. or maybe some beta firmware for the PTV3000 that might help me out?

As I understand it, if you use your Nexus 4 to stream using the PTV3000, the audio stutters and video drops. Am I correct?

Levistras

Yes

I do apologize for the inconvenience.

Since you have another device that is not having the same issue, that means the issue is isolated on your Nexus 4. You may need to check the audio and video settings. I do apologize, but our support is only for the NETGEAR device. Your Nexus 4 is beyond my scope of support.
