Raspberry Pi – unable to connect WiFi network with external adapter

Recently I’ve been configuring Raspberry Pi B+ for Wireless connection. I’ve configured everything in:

/etc/network/interfaces and


I was trying to connect to hidden network, but without success.

In Raspberry I installed additional WiFi dongle – TP Link TL-WN725N, adapter was successfully recognized as wlan0 interface without any problem, I was also able to scan wireless networks around me – great but why I can’t connect to my network? 🙁

After some time of research, I found this topic:


Raspbian has drivers for WiFi adapter but in my case TP Link adapter was in version V2, so additional drivers are required for working properly. Thanks to MrEngman post I was able to download additional drivers ( I’ve created also backup of this script ) – you can find it here:

To install this on you Raspberry Pi type:

tar xzf install-wifi.tar.gz

Then run:


To find out more options of this script run command

 ./install-wifi -h

After installation reboot your raspberry and everything should works fine 🙂
