FSF Certifies Atheros-Based ThinkPenguin 802.11 N USB Adapter

gnujoshua writes "You may recall that last Fall, the LulzBot AO-100 3D printer was awarded the use of the Free Software Foundation's Respects Your Freedom certification mark. Today, the FSF announced certification of the ThinkPenguin TPE-N150USB, Wireless N USB Adapter, which uses the Atheros ARAR9271 chip. The FSF's RYF certification requirements are focused on the software (not the hardware designs) of a product, which in this case was primarily the device firmware and ath9k-htc module in the Linux-libre kernel. (Disclosure: I work for the FSF.) There's also a cool story that is within this story... which is that the firmware for the Atheros AR9271 chipset was released as a result of a small device seller (ThinkPenguin) striking a deal with a large electronic device manufacturer (Qualcomm Atheros) to build a WLAN USB adapter that shipped with 100% free software firmware. This deal was possible largely because two motivated Qualcomm Atheros employees, Adrian Chadd and Luis Rodriguez, made the internal-push to get the firmware released as free software."

Master Mode

one thing i noticed last week on ThinkPenguin is that their adapters generally support Master Mode making it easy to build access points. i don't think this can be said for most adapters requiring ndiswrapper.

The wifi part of the hardware does. One of the reasons we opened up the firmware was to let people at it to make it better at supporting master mode.

The NIC has a small embedded CPU to act as a PCIeUSB gateway and a small amount of RAM to run code and buffer frames. The problem with master mode is the amount of RAM that you need for each associated station. So there's been discussion about moving some of the stuff done in the NIC CPU (transmit aggregation, rate control) into the host, so the NIC itself doesn't need to store (that much|any) per-station state.

Re:Yeah, but $54 for a USB Wifi?

Freedom isnt about cheap and it never was.

A dongle that 'just works' today with a particular binary wont necessarily work tomorrow on a different machine or after a simple recompile with different options, let alone after a major software upgrade.

At the moment this appears to be the only properly supported wireless dongle on the market. It should be no surprise it's a little more expensive than the junk.

As a matter of fact, I wish it "just worked".
I have one of these dongles, and last time I tried to use it I was hitting this bug:
https://lists.ath9k.org/pipermail/ath9k-devel/2011-November/007467.html

This is a bug from November 2011 is against the same chipset. But, it was a module that was loading proprietary firmware.

The firmware was released as free software within the past couple of months. So, now instead of the ath9k kernel module folks having to treat the firmware as a black box, they can file bugs and submit patches to the firmware itself.

The reason we certified this device is because it carries freedom to the user. Not arbitrary freedoms, but the specific freedoms to run the program, share it with others, make modifications to the source code, and share modified versions of the source. With this freedom, a user can not only work with others to find and eliminate bugs, but they can find ways to adapt and improve the software so as to squeeze the most they can out of the device. The same can't be said with the 2011 adapters that shipped with this chipset.

And, this isn't just idle speculation. Already we have seen a fair bit of cooperation between this firmwares lead developers and the ath9k module maintainers. I would be very surprised if the almost two-year old bug you pointed to still exists. But if it does, then at least I know you and I can easily reach out to a trustworthy community of free software hackers to explain to us the problem.
