Unable to connect to the internet on Ubuntu MATE
 

Hi
I'm attempting to access the web with a TL-WN722N wireless adapter. I was told this adapter had good compatibility with Linux out of the box, which is why I purchased it.

I can't get online at all, my wifi is not detected. I can't use the sudo apt command to get extra packages because I'm not connected to the net.

I'm writing this on Windows 10 via dual boot. I would not be able to access the internet otherwise.

I tried the sudo iwconfig command:
lo no wireless extensions
enp2so no wireless extensions

Any help would be appreciated.

Does the USB system detect the wireless adapter?

There now appears to be 3 versions of the TL-WN722N. The first version used an atheros chip which is probably why someone told you it was good to use with linux. v2 uses a Realtek rtl8188eus chip and there has only recently been an rtl8188eu driver added to staging.
You could also download the driver from Realtek for linux from a TP-Link site and there are lots of rtl8188eu repos on github as well.

I have no idea what chipset the version 3 uses.

ruizu1990,

Welcome to LQ.

I suggest that you get a refund on the TL-WN722N.
Ages ago I bought a TL-WN727N, which was supposed to work in Linux. It doesn't.

The D-Link N150 USB wifi adapter works:

There are also plenty of these brand new (old stock) on ebay.

Also see post #7 by cwizardone regarding rtlwifi on:

That post by cwizardone is only applicable to the PCIe adapter. The usb adapters don't have that register.

briselec,

Thanks for that info.
