EDUP 802.11n Mini Wi-Fi Adapter Sleeping

 

I bought some EDUP 802.11 N Mini Wi-Fi Adapters from China.  They’re cheap and do a fine job plugged into my Raspberry Pi’s.

However, by default, they always go to sleep which makes it difficult to connect to them via ssh etc.  To fix this, here’s what I did:

To identify the USB WLAN Adapter I did the following:

Then:

From that I was able to derive that the WLAN adapter was using the rtl8192cu drivers.

A bit of Googling later, I was able to disable power management on the Wifi adapter, like this:

Reboot…

Run:

It should return 0 if the power management is off.

Bask in the glory of your WiFi adapter that stays up all the time 🙂
