Sorry I missed out the power management option in that modprobe.

Is the connection stable .. or does it disappear after a minute or two ?

if it's unstable, try:

Code Select Expand

sudo modprobe -r 8188eu
then just in case you've rebooted:

Code Select Expand

sudo modprobe -r rtl8192se rtlwifi mac80211
then

Code Select Expand

sudo modprobe 8188eu rtw_power_mgnt=0

and let me know if it's NOW stable.

if so, THEN we'll carry on.

Tested that too, doen't works either...

But I have a connection and an IP adress, see that:

wlan1     Link encap:Ethernet  HWaddr 64:66:b3:23:fc:2b 
          inet addr:192.168.0.16  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::6666:b3ff:fe23:fc2b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:25 errors:0 dropped:52 overruns:0 frame:0
          TX packets:55 errors:0 dropped:1 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:3185 (3.1 KB)  TX bytes:10960 (10.9 KB)


Very weird...

Experimentations ? Oh yeah I love that !

So, here is my lsub results:

And for modinfo:
[email protected]:~$ modinfo 8188eu | grep rtw_power_mgnt
parm:           rtw_power_mgnt:int


I try your command with rtw_power_mgnt, but after that...
[email protected]:~$ ping -I wlan1 google.com

Does't works... :/

Hi and thanks for the tips,

I followed all your instructions, one by one and the dongle come back to life... for a moment.

Indeed, my network manager connected succesfully to my Wi-Fi network and I have access to Internet. But after a few second, the network manager show me that there is a low wi-fi connection, I still connected to it, but no internet...

Did you have this trouble ? How did you fix it ?

Using Ubuntu 12.04.3-LTS linux-3.8.29-generic with TP-LINK TL-WN725N Ver:2.0

Thanks for help !
