Has anyone else had issues with the Edimax EW-7811Un? I am just doing a first experience with all of this and the pi works fine, tested it with my powerline networking kit but as soon as I plug the wifi dongle in I start having networking problems. I have had 326,000 dropped packets in an hour of uptime on just wifi. Do I have a bad dongle or do I need to be looking somewhere else? Under any kind of load (watching movie, streaming flac music, etc) I have latency of 3152ms too. WIth no load (after things settle) I can get normal pings below 30ms.
I am using the apple ipad air power brick so it should have plenty of juice (its 2.4A).
Anyone have similar issues they got fixed?
Other than that I am really enjoying it. CEC is even working pretty well! Once the hifiberry supports dts and dd passthrough ill be getting one of those onto the board too and getting rid of the hdmi audio splitter I have wasting an outlet now.
Wireless is not recommended for Rasplex, use Ethernet or powerline adapters, especially if you want to stream anything over SD content, OK for streaming just music.
Is that because of speed or because of kernel/driver/compatibility considerations with the Pi? Wireless n speeds (150mbit) are more than enough to stream full HD (about 5Mbit). Even acknowledging networking overhead and that most wont get 150mbit, that gives well more than enough room for streaming. If its related to the openelec team not being able to maintain driver compatibility though I do see that as a separate thing (and understandable). If there is another dongle that is reliable I am willing to make the switch.
I know that it works with my Pi2 & Rasplex 7. However I cannot say whether or not it’s good enough for video content. I’ve got 2 x RPi2 - one for videos where I use a dedicated wireless bridge and one for audio which is where I’m using the USB wireless adaptor. I have to say that with the low throughput needed for audio it works without a glitch.
Have to agree with Mr Clark, I use an old RPi1 B+ with a HiFiBerry card and Rasplex as a headless music streamer with the Edimax dongle you have, works fine. However, with hi bitrate 1080p video there may be issues, dependant on a number on factors which is why it is recommended that Ethernet is used.
even if you take the 1080p factor out of things, i couldn’t even stream flac audio on the wireless card without the issues rearing their head. ned are you on 7 too? edimax said the drivers may not be compatible with the newer kernel
To add to Ned’s last comment - I wirelessly stream fairly high quality FLAC files on my RPi2/Rasplex 7, and have never had a problem (so far!).

Update to it all, I put a powered hub on and it seems to have relaxed the issues a good bit. Im still not able to pull 1080p over wifi but now it looks to be much more clearly a wifi bandwidth issue. Are either of you running it directly off the pi or do you have a powered hub on?
And does anyone know what linux utilities are built in to the rasplex build for wifi troubleshooting? (connection quality, xfer speed, etc)?
I suppose now I’m going to have to start to consider hardwiring. The power line adapter is giving about the same performance as the wireless because of the wiring in the house.
Unfortunately there are no such utilities in Rasplex. Have you tried assigning a fixed IP to the RPi on your router. I personally have the Edimax dongle plugged directly into the RPi. Is it possible to try another wifi dongle, the one you have may be faulty!
In response to the question asked earlier, I am successfully streaming 720p / 1080i video and high quality FLAC audio over wifi to my Pi2. I’m using a “Wi-Pi” adaptor. There’s a little FCC ID on it that says DYR-Comfast88.
One more data point: I just got a 2nd wifi adapter, a TP-Link TL-WN823N. Although I had no complaints about my “Wi-Pi” adapter, my router statistics show a much higher connection rate to the TP-Link adapter. The router and Pi are in the same location; the only difference is the wifi adapter:
TX-Rate RX-Rate Sig Quality
Wi-Pi 78M 58M 59%
TP-Link 130M 104M 64%
Although the original subject was about wifi woes, it’s easy to overlook your Plex Media Server configuration. For example, if a file format is not natively supported by the Pi, it’s MUCH better to let it be transcoded by the PMS. Also, a lot of Blu-Ray files have gigantic bit rates. You should experiment by configuring PMS to send at lower bit rates if you run into buffering problems. Personally, I would much rather have a slight loss of video quality than watching a movie that constantly stops while it re-buffers.

I’m using an edimax AC600 and it works perfectly, no buffering @ all unlike the previous N150 adapter I used!
It’s gotta be said my RaspberryPi2 (with Rasplex) seems to be better then my Roku3 when it comes to streaming stuff!
The new wireless adapter on wireless n 2.4ghz fixed the streaming problem… Now if I could just find a power adapter that doesn’t give me the low voltage warning…
