I just moved house and our new house doesnt have ethernet ports in the walls so I needed to install a wireless card into my xubuntu file server running 16.04 lts AMDx64

I'm currently connected using a usb wireless dongle @ 150mbps

Wireless card: TP-Link TL-WN851N (Wireless N 300mbps)

I managed to get it to recognise an unclaimed network using

sudo lshw -C network

*-network UNCLAIMED
   description: Network controller
   product: Tul Corporation / PowerColor
   vendor: Tul Corporation / PowerColor
   physical id: 6
   bus info: pci@0000:01:06.0
   version: 01
   width: 32 bits
   clock: 66MHz
   capabilities: pm bus_master cap_list
   configuration: latency=64
   resources: memory:fbaf0000-fbafffff

I cant find the Ath9k driver and my backports are enabled.

rfkill list all

Gives no results

Can someone please help me.

    Could you give the result of lsusb and sudo iw dev? if your USB device as an atheros chipset it requires ath9k_htc (ath9k is for internal cards). The driver is present by default, it should work out of the box... – kcdtv Jan 17 '18 at 11:19
  • I believe it is a PCI device. Please edit your question to add the result of the terminal commands: lspci -nnk | grep 0280 -A3 and also: sudo modprobe ath9k – chili555 Jan 17 '18 at 15:39
  • Ups... You are right chili555: it is a PCI device, not an USB device. So the lsusub command given before is not useful; the lspci command you gave is the one relevant here. – kcdtv Jan 17 '18 at 19:12

  • it is a PCI device and I cant remember the code but i couldnt find Ath9k driver on my machine – Ben Heininger Jan 20 '18 at 12:41

So according to WifiDocs

Tested on Ubuntu 11.04 Due to a kernel/driver issue, download rate is slow (max 300kiB/s with 802.11g) and slower than upload. Installing wireless-compat didn't help

I suspect this card doesnt work with Xubuntu at all.

Looks like I need to buy a new Wifi card!
