Ok I have run all the tests!
These are my test conditions/equipment:
I live in an apartment building with most people having 2.4GHz network.
I have my windows 7 laptop connected to the router via gigabit ethernet.
My router is D-link dir-868L.
Both frequencies are enabled (2.4GHz and 5GHz)
Raspberry Pi 2 is 3 feet away (almost a meter) from the router.
My network attached storage is Synology DS 214 Play.
The external hard drive used is Seagate backup plus 1TB formatted to ext4 and it's externally powered.
Playing Interstellar.2014.1080p.BluRay.REMUX.AVC.DTS-HD.MA.5.1-RARBG (42.7GB; Potplayer reports overall bitrate 36.2Mbps) - with no advanced settings!:
Osmc 2015.08-1 with all of the over the air updates:
EW-7811UTC 2.4GHz If you skip ahead frame rate will drop and you will loose sound, have to pause and then everything is ok
EW-7811UTC 5GHz Everything works fine, even with big jumps, continues playback with no problem
EW-7822UAC 2.4GHz Everything works fine, even with big jumps, continues playback with no problem
EW-7822UAC 5GHz Everything works fine, even with big jumps, continues playback with no problem
Openelec 5.95.5
EW-7811UTC 2.4GHz If you skip ahead frame rate will drop and you will loose sound, have to pause and then everything is ok
EW-7811UTC 5GHz Everything works fine, even with big jumps, continues playback with no problem
EW-7822UAC 2.4GHz Everything works fine, even with big jumps, continues playback with no problem
EW-7822UAC 5GHz Everything works fine, even with big jumps, continues playback with no problem
I haven't tested some larger distances (I can't) but wireless speed will drop with larger distance and more obstacles in the way (walls etc), at that point I'm not sure if playing a high bitrate video would be as smooth as it is now.
In regards to live stream tests, I tested both EW-7811UTC and EW-7822UAC adapters with both OSMC and Openelec, with both frequencies, I haven't experienced any stuttering or dropouts, everything worked just fine.
I used TV Ontario for tests, ustvnow requires login information and I didn't want to waste time with that.
Testing usb sockets:
I couldn't reproduce my previous situation which made me think that it made a difference where you plug in some of your usb hardware.
I did my previous tests without shutting down the Raspberry Pi 2, it seems that was the reason for my weird results.
If you shut down your Raspberry Pi 2 everything will work as it should without weird results.
Sorry Popcornmix!
I've found out that there is a difference between using ethernet-wireless and wireless-wireless connection.
if I use ethernet with my laptop and wireless with Raspberry Pi 2 I would get these results:
Openelec
2.4GHz: 7.71MB/s
5GHz: 11.32MB/s
OSMC
2.4GHz: 10.17MB/s
5GHz: 15.6MB/s
First of all this shows that speeds over 10MB/s can be achieved with this wireless adapter and that OSMC at this point has better drivers!
Wireless - wireless transfer:
Openelec:
2.4GHz: 3.3MB/s
5GHz: 5.44MB/s
OSMC:
2.4GHz: 7.02MB/s
5GHz: 7.97MB/s
This definitely proves that OSMC has better wireless drivers, at the same time as far as I can see the router might be slowing things down or there's some additional overhead which I'm not aware off (wireless-wireless overhead?)
One more thing, I tested again the scenario with Openelec and ext4 and NTFS hard drive (same one just different format)
NTFS is faster for wireless transfers (Either ethernet-wireless or wireless-wireless).
But slower for ethernet-ethernet or wireless-ethernet.
I'm not sure why this happens.
Nevertheless I hope that Openelec team will manage to sort the drivers out, and make Openelec ethernet and wireless transfer speeds faster.
