View Full Version : PiCorePlayer and Edimax WLAN Stick

2016-06-19, 10:14

I'm new here in the forum and also new in dealing with Squeezelite . Before I write , I would like to apologize for my bad english and hope I still get help .

I have a Raspberry Pi2 and it piCorePlayer installed . This I would like to operate by WLAN , plus I use the EDIMAX EW - 7811Un .

Unfortunately breaks here with me again and again the connection from what is probably the most energy-saving mode .

On my second Raspberry I then installed Max2Play. Again, I had connection problems, but this I could fix:

sudo nano /etc/modprobe.d/8192cu.conf

In the file I wrote :

# Disable power management
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

This does not work on picoreplayer . This does not know the commands over SSH .
Does anyone have any idea how I can solve the problem ?

Is that perhaps the user commands ?

Would really appreciate the help .

hi hagene,

piCore is a little different to Raspbian.

$ cat /etc/modprobe.conf
# /etc/modprobe.conf: Modprobe config file.
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

Use the [Diangostics] button on the [Wifi Settings] page to get more information. You need to be in [Beta] mode. This will also generate a log file.

Hi Greg ,

Thanks for your answer.

$ cat /etc/modprobe.conf
# /etc/modprobe.conf: Modprobe config file.
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

how exactly do I have to enter code in putty it works?

so far I have still disconnects as far as the wireless connection .

you can see on the picture.

here the log file . can you see something?

as I said, at max2play it works after I have the command entered .

You shouldn't change anything. The commands you wanted is already in piCore (as Greg showed you).

If you look at your ifconfig output you can also see:

Power Management:off
Indicating that power management is already off
So I don't have a good explanation at the moment
I need to look into this.

hi Stephan,

Thanks for posting your wifi diagnostics results. From what you posted everything looks good to me.

I would like to see what wifi networks are close by and what channels they are using. I like to use an unused channel.

I am starting to wonder if the driver has been updated, how to work out what version of the driver we are using?

thank you for your answer.

Here the desired data .


ok , the power management is therefore allegedly made ​​already .
but looks to me like as if that were not the case . Strange .

As I said with MAx2Play it was that way. but when I turned the power managment went well .

What can that be , you have an idea?
