nolinked power save enter <-> leave

[pnpavlov]

Hi,

I tried two approaches to configure my TP-Link T4U AC1200 USB stick on Fedora 26 running

# uname -rvi
4.12.8-300.fc26.x86_64 #1 SMP Thu Aug 17 15:30:20 UTC 2017 x86_64

I tried doing git clone https://github.com/gnab/rtl8812au.git and then

# Option A 
cd rtl8812au/
make
cp 8812au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
depmod
insmod 8812au.ko

Then cleaned up and did

# Option B
cp -rf rtl8812au/ /usr/src/8812au-4.2.2
dkms add -m 8812au -v 4.2.2
dkms build -m 8812au -v 4.2.2
dkms install -m 8812au -v 4.2.2

Both time compile time I'm good and module is loaded. Then the USB stick blinks few times when I turn on/off the wifi from the gnome manager. Unfortunately I can't see any network and I can't connect to "hidden network" using my SSID & Pass. dmesg is also not very helpfull...

Any hints?

Hey, I got that very behavior when trying to build the driver for Raspbian (as an experiment),

I thought I just misconfigured something on wpa_supplicant level because wpa_supplicant was complaining about not being able to connect to driver in its logs.

Now that I tried getting it up and running again on "vanilla raspbian" on raspberry pi 3, I think this may indeed be a driver issue

[pnpavlov]

Yes, seems so... anyone, hint how to solve that one?

[guysoft]

Same issue here, still no solution?

Did you try disabling power save with sudo iw dev set power_state off? I have the same problem, I am trying to see if it helps - for now it does but the problem tends to appear quite randomly (maybe as soon as the power state kicks off).

[kimocoder]

power saving may be disabled in Makefile too

[guysoft]

Is there a way to test if it has been disabled? I am still stuck on this.

Yes there is this command line to be sure if power save is enabled or not $ iw wlan0 get power_save wlan0 to replace with the appropriate wifi interface you are using.

But it doesn't resolve the problem to set power_save to off with the command below: iw wlan0 set power_save off

So i still get the same message in the log: **[ 3296.902501] ==> rtl8188e_iol_efuse_patch [ 3297.206644] R8188EU: nolinked power save leave [ 3299.211501] R8188EU: nolinked power save enter **
