Hello all,
I am using Realtek RTL8188SU WLAN Adapter and writing to seek help, because I have connectivity problems. Every now and then the wireless disconnects and refuses to reconnect. I have read on other forums that this could be due to the driver (r8712u), and that I should get the Realtek driver. I downloaded from realtek.com, but I get the following message when I try to install:

I also read that I should try the rtl8192su driver from https://github.com/chunkeey/rtl8192su but I could not compile that either.
Any suggestions how to compile the driver? Or should I do something different in order to have a reliable wireless connection.
Thanks.
