Linux wireless adapter drivers

selwonkak · Jan 9, 2016

I have the TP-Link TL-WN881ND wirless adapter and linux mint 17.3 cinnamon. It needs a driver to run (I think) and doesn't work at the moment. The computer is too far from the router to plug it directly in.
where can I get the correct driver and how can I then use it on my computer (put driver onto computer through usb stick?)

sorry if this is in the wrong section of the forum.

This page says that it many kernels have the driver already --http://www.linux-hardware-guide.com/2012-11-01-tp-link-tl-wn881nd-wireless-n-pcie-300mbps
But from reading that page it sounds like you need the ath9k driver.

If needing the driver is the problem, how do I get it? I don't want to move the computer to use an Ethernet cable, so can it be done using a usb stick?

Package installation is always easier with the built in tools. They work better with an ethernet connection. Laying a cable across the floor is probably far better than trying USB.

You misunderstand, the driver (ath9k) and firmware (chipset ar9287) already come pre-installed on mint. Nothing else you need to do. You can confirm this by looking out output of
sudo lspci -vnn
And check dmesg output and ifconfig output.
From briefly poking around it seems the driver for ar9287 chipset is just of poor quality :/

I tried re-installing mint and had the same problem. I then tried using ubuntu and it happened as well. Is it the adapter itself?

selwonkak · Jan 10, 2016

could the driver be old/ missing on a new install of both mint and ubuntu?

I don't know if this works but THIS PAGE has one man's solution.

Also, you might need to open the Mint drivers manager and enable the proper driver, if it's listed.

I have tried that, but it says that file doesn't exist. I have tried the touch and cat commands, but neither can create a file. Is there something I don't understand?

kanewolf · Jan 11, 2016

Are you doing "sudo touch" since you probably need root permission.

selwonkak · Jan 11, 2016

I am doing it as the root user - after the sudo -i command. I am doing it this way because I thought that was the problem and wanted to be sure.

I have movwd the pc downstairs, aand the same problem happens when manually wired to the router...

skittle · Jan 11, 2016

aand the same problem happens

What problem exactly? It is not clear whattheissue is. Please post output of dmesg (after plugged in and sudo ifconfig

how much do you need? I am on aother computer so can't cut+ paste, and don't want to write 10 pages(size 12, a4 in libre office, was going to move via usb stick, couldn't find how to move file to memory stick!) out here. the first lines, that are repeated a lot and look wierd are:
13.7] ath: phy0 failed to stop TX DMA, queses=0*009!
13.8] ath: phy0: DMA failed to stop in 10 ms AR_CR=0*00000024AR_DIAG_SW=0*42000020 DMADBG_7=0*00008040
13.8] ath: phy0: could not stop RX, we could be confusing the DMA engine when we start RX up

a lot skipped

in the previous answer, a * represents a times symbol.

and the

This looks like hardware/bios/driver issue

What motherboard do you have? Is IOMMU enabled in bios? (enable it if not)

selwonkak · Jan 12, 2016

skittle :

Enabling IOMMU fixed the problem.
