With the recent upgrades provided by osmc is this problem solved? both wifi firmware and kernel has been updated the last few days?
Will tere be a image available with a snapshot when these issus has been resolved? Right now I’m limping, using rasbmc on my wifi device and osmc on the device connected to lan. And since I have shared db thru my nas I don’t want to be running diffrent versions.
Kind regards!
Just to confirm: updated from RC1 to RC2 and now my Edimax AC600 usb wifi (rtl8812au) finally rocks so that I could actually move from OpenElec to OSMC 
Thanx for that!
Report back that TPLink with Realtek 0bda:8178 works fine with 8192cu in rc2! thx! I’m off raspbmc!
That’s the exact same adaptor (TP-Link TL-WN823N) as one of mine - and out of the 4 adaptors I have it is the best performing one in OSMC. I’m getting nearly 100Mbps measured throughput on a Pi 2 through a wall between two rooms! Definitely recommended.
Yea I have noticed excellent throughput! When ftping the unit I get about the same speed as I get on the wired rpi2. So I’m also very pleased. Also have not had any problems with freeze or drops either, I get stable pings from the unit and have not had any problems with reboots or anything like it. So I also recomend the tp-link wn823N 
Did some iperf with my Edimax EW-7811UTC configured to use 802.11ac on my Rpi2: I get ~135Mbps (+/- 10Mbps), upload as well as download.
Two walls between my router and my Pi, but only 3m apart.
Even copying files using Samba results in ~15,5MB/s written and read.
Quite nice
Reporting that with RC2, “D-Link DWA-131 rev B1” works like a charm. Just not as fast as what others report on different adapters.

Its not working well with this kernel:

wich driver i need to install and how¿¿¿
many thanks
That’s because this is not the OSMC kernel - you have installed a generic Raspbian kernel which does not have the same wifi drivers.
This was explained to you already in this thread:
To go back to using the current OSMC kernel on a Pi 2 do the following:
sudo apt-get update
sudo apt-get install rbp2-image-3.18.10-1-osmc --reinstall
reboot
I am unable to run lsusb command for some reason. Would it be possible to include this wifi usb adapter WDN3200, chipset RT5572. https://wikidevi.com/wiki/TP-LINK_TL-WDN3200 Thank you

Are these no longer supported, or just temporarily missing?
Full debug logs please.
The RT5370 chipset is definitely supported. I’m not sure about the other one.
Hmm, tricky that. I can’t ssh in as the wifi doesn’t connect, and if I connect an ethernet cable, connman uses that, so no attempt to initialise the wifi. I don’t have a keyboard to plug in, can I put anything in config.txt or cmdline.txt to force a log?
You can turn on debug from system settings, and then shutdown, and boot with ethernet disconnected. This will create a log with the startup bits in.
You can then turn off debug (optional), shutdown and reboot with ethernet connected and get the old debug (kodi.old.log) which has those bits in.
I’ve probably made that over-elaborate, but you’ll get the gist

ok, managed that
Nothing apparetly useful in the kodi logs, the only comms related entry is…

Are people having any strange problems getting the Edimax EW-7811UTC working reliably? It does seem to work some of the time, but hangs a lot during the scan of media when Kodi starts up, or drops off the wifi now and again. very random. I’ve updated to RC3 which doesn’t seem to have helped. Also using a good 3A power supply with the RPi2 with only a USB iR adapter, which if I unplug doesn’t help either. I also tried enabling the extra USB power Pi setting and using a powered USB hub which didn’t help either.
I’m wondering if my Edimax EW-7811UTC is faulty, however does seem to work more reliably near the router, although it’s not that far from it in the Lounge (one floor down vs one room away). I wondered about trying the EW-7811USC as this has a high gain antenna, but I’m not sure if this needs another driver or would help anyway?
Plus it works in my PC fine, and I get very good speeds ~20-25MB/s! with it in the same place in my lounge.
Or have I got a slightly different version of the EW-7811UTC, so the driver doesn’t quite match or something?
I believe this wifi dongle is draft ac, so maybe I need to try a final ac dongle. Which are supported/tested?
Here is my output… is something wrong the fact it says it couldn’t open device?

Let me know how to provide more detailed logs if that would help.

Bit more info on this problem. If I ssh onto my RPi2 as root I don’t get the “Couldn’t open device, some information will be missing” message when running lsusb -vvv…

I’ve also noticed the led on the dongle is flashing continously, crazily, all the time, even when it’s not trying to scan my media drives (SMB) or play anything. So much so, I think this sometimes locks up my 5Ghz wifi network that it’s connected to (some of the time at least). This clearly isn’t normal!
My router is a good one - Asus RT-AC66U and firmware up to date.
Is there any other commands I can use in ssh to see whats going on? It’s bizare that ssh type activity is fine though. Can I install the wifi driver myself? Not sure how though…
I turned on debug logging, got some big logs. Shall I upload them somewhere for review?
Please help!
Thanks
Edimax EW-7811UTC AC600 Wireless works in 2.4GHz mode. It doesn’t detect 5.0Ghz mode at all.
I think there were discussions around this that concluded that adapter was 2.4Ghz only.
