I got an ALFA AWUSO36H usb wifi adapter and I cannot get it working properly. It looks like it keeps connecting and disconnecting from my computer. I tried several things to make it work none seems to have made anything change.
The modules used by this device are :
rtl8187and
ieee80211Those drivers seems to be already installed on my computer.
I also got those by the vendor but when trying to build them I got the following errors (not sure if this is relevant):

So here is the output of my dmesg, it keep to repeat the same error over and over again :

$ uname -srv
Linux 4.12.8-2-ARCH #1 SMP PREEMPT Fri Aug 18 14:08:02 UTC 201I also tried on Kali Linux to see if I could get it working but it was the exact same.
Except googling more about this in hope to find something, I feel pretty much out of ideas for this one.
Any idea how it might fix this?
Thanks a lot
Edit :
Found here that the rtl818x drivers are "Ad-Hoc since Linux 3.4" ... Does that mean that I need to use a different driver, or that I can't get the rtl8187 to work without having a prior to 3.4 kernel?

The device is supported by the kernel so you don't need to compile drivers. Do you have a lot of devices connected with USB?
Ad-Hoc since Linux 3.4 means that the kernel module has supported computer to computer wireless connections since the 3.4 kernel

No I tried with no other devices connected and also on different ports with same result.
Since yesterday I also tried it on win10 with no other results than the device continously connecting and disconnecting. So it's probably not at all a software issue.
I'm starting to think that the wifi adapter is somehow broken as many people on forums said that it's just plug n play..
I'll try with another usb cable tomorrow but I highly doubt that will change anything. If that doesn't work I guess I'll be good for buying another wifi adapter.
