Hello everybody,

I can easily replace our Intel wifi card that doesn’t work with free firmware. We don’t need to disassemble the whole laptop, just to remove a huge backplate, and the whole motherboard is there. Yet I don’t know what Wifi card to look for. I thought an Intel wifi card would be fine, and it isn’t.
I don’t want to buy a USB wifi stick since we can install a wifi card *inside* the box.

You can... if the manufacturer of the laptop does not impose unjust hardware DRMs (to force you to replace the card with one it "approves"... through a business deal). Apple, Dell, HP, Lenovo, Sony and Toshiba are known to impose such DRMs on Wifi cards. Not all their laptops are affected though.

http://libre.thinkpenguin.com and https://tehnoetic.com are the only two vendors that guarantee that 100% free Linux kernels (no proprietary firmware in particular) properly drive all the hardware they sell (including internal Wifi cards). They both internationally ship.

AFAIK, these are the best WiFi cards compatible with fully free systems:

AR5B95 is a Single Band 150Mbps card compatible with free ath9k driver, therefore compatible with fully free systems including Trisquel.

It's not high-end as https://tehnoetic.com/tet-n300db (Dual Band N300Mbps), but it gets the job done. :-)

Yeah.. and if they are in 'murica it will get the job done till 2057, which is the year their Internet connection will exceed 150Mbps.

The internet speed s^cks though so it does not matter, however the LAN streaming may matter.

The higher the maximum speed of the WiFi adapter, the faster it is on any Internet connection type compared to lower-end WiFi adapters.

Are the Atheros wifi cards the recommended devices for a Lenovo T400? I'd like to replace my current card without paying a steep price.

The Atheros WiFi cards will not work in a T400 with the original proprietary BIOS (because of a whitelist). However, they will work in a libreboot'ed T400.

Known to work:

Atheros 150Mpbs Single Band:
