ASUSTek N10 Nano

[Lazzu]

The connection dropped constantly on my Ubuntu 16.4 desktop with the N10 Nano, so I installed this driver instead. Now I haven't experienced a single connection drop after that. But my speed still isn't the same and the ping is going everywhere. I'm not sure if it's because my AP is also my Nexus 6 Android phone, but I haven't experienced anything like this on my lenovo laptop using wireless. Also when I plug my phone to my desktop with USB and share the internet that way, I get the full 100mbps connection I should be getting from the phone. With wifi my download speed is only about 40mbps when testing with speedtest.

But hey, at least it hasn't disconnected yet! That was the most irritating issue and now I'm happy using the wlan dongle again. The other issues I am mentioning might as well be caused because I am using the phone as my AP. Also the mobile network I am using is known for not always giving 100% of the highest of speeds for the users, so it might be that too.

As a late update: I found that instability was often caused by power management issues. That being said, now, the rtl8xxxu driver from the mainline kernel works pretty fine these days. That's what I'm using now myself. You may still have to troubleshoot NetworkManager, though: in particular, consider disabling power management. Disabling it made the rtlxxxu driver work well for me.
