Hello,
I've just bought a "TP-LINK 150Mbps Wireless N Nano USB Adapter" (Model No. TL-WN725N). Below is how Linux identifies the device:
dmesg (immediately after plugging it in):
| Code: | [ 948.016228] usb 4-4: USB disconnect, device number 3
[ 954.913645] usb 4-4: new high-speed USB device number 4 using ehci-pci

After failing to identify which wireless driver to enable in the kernel, I downloaded Ubuntu 14.04 Live to test if the USB wifi dongle is supported by Linux. This test was successful and I was able to connect to my router (and the Internet) using wifi from the Ubuntu Live environment.
I ran lsmod to see which module may be used for the USB wifi dongle. This is the list of modules loaded in Ubuntu:

The only interesting one seems to be r8188eu. However, I can't find anywhere in the kernel to enable this module in Gentoo. I am using kernel version 4.1.12.
Can someone please point me in the right direction for getting this USB wifi dongle working in Gentoo?
Cheers,
Martin[/code]
