I can confirm this fix also works for my cheap Fast R8188EU based dongle - http://imall.iteadstudio.com/wireless/gsm-gprs-and-wifi/fast-mini-wifi-usb-adapter-150mbps-dongle.html.

Thanks to you both for the update and the clear instructions.

Thanks,
Bill.

In piCore-5.3alpha1 driver built from unmodified source, means Power saving enabled. Please try, whether there is a change or not.

Appears that rtl8188eu (TP-Link WN-725n) regression is back.

At least iwconfig shows power management off.  I have a generic adapter that works with 5.3a1.  Will post that next.

Rebuilt rtl8088eu driver from 3.12.9 source, wireless-3.13.6-piCore+.tcz updated in repo. All other items unchanged. Please try.

Hi bmarkus.

It seems like support for this wifi is broken again in the 3.14 versions of piCore and piCorePlayer.
I noticed that MREngmand who has been providing drivers for this wifi in the raspberry forum, stated that the new version was working, but it needed a firmware. It needs rtl8188eufw.bin which is not included in our rtlfirmware package.
http://www.raspberrypi.org/forums/viewtopic.php?f=91&t=29752&start=175

So maybe we need this firmware in our firmware package?
Or would it be better to continue rebuilding an older driver for use in the newer kernels?

Better to try the current 3.14.y driver. Can you provide the missing firmware? If so, I add it to firmware-rtlwifi.tcz

Installed latest firmware with WN725 NIC and 3.14.0 kernel (piCorePlayer 1.15 image).  It appears to work correctly on initial installation.

Sorry about reviving this old thread, but I have just updated Steen's piCorePlayer to version 1.15e (kernel 3.14.2-piCore+) and again my TP-Link WN725N v2 USB NIC (r8188eu) does not seem to work. I have tried to repeat previous instructions for an older kernel (older post in this thread), but it does not seem to solve the problem. Could anybody please provide me with instructions on how to get it back to working condition? Did you work out a permanent solution (or work around instructions that work across different kernel versions) for this problem? Thank you very much.

As piCorePlayer comes with its own kernel usually better to discuss it on the piCorePlayer page.

However I would appreciate if you could try the current piCore-5.3rc4 with your setup and report back here.
