EDIMAX EW-7612UAn V2 THE ONLY (?) GNU Linux WIFI WLAN Adapter that works OUT OF THE BOX on all GNU Linux systems (ODROID RASPBERRY AND Desktop GNU Linux)

different sizes… different standards… every year? why?

  • it is hard to find wifi cards that are supported by open source drivers
  • even worse: there seems to be NOT A SINGLE wifi card vendor, that makes the firmware public (why actually?)

SIMPLIFY! SIMPLIFY! SIMPLIFY!

or end up in “THE-MASSIVE-MESS-OF-USB-CABLE-PLUG-STANDARDS”

possible alternative (not for notebooks, but for workstations/PCs): PC <-LAN-> Wifi AP-Bridge <-> Wifi <-> Internet

Wifi Accesspoint that connects to another Wifi Accesspoint (Client-Bridge) – TP-Link can do that – WLAN AdHoc Client Bridge with tp-link tl-wr841nd v11 – use wifi router as wifi usb adapter

in search for a replacement for the card on the very left: (keywords are: wifi atheros 2230) or (RTL8852AE 2230)

ONLY BUY FROM HARDWARE VENDORS THAT SUPPORT FREE & OPEN SOURCE SOFTWARE!

finding the right open source supported wifi chipset, dongle, or network card, IS HARD.

  • sometimes the only option is – to remove the internal wifi card and replace it with an external usb dongle
  • this article tries to make things easier, to provide info “what worked”.

“Currently there are only a few modern wifi chipsets readily available that work with free software systems”
For USB wifi devices this list includes the:

  • Realtek RTL8187B chipset (802.11G)
  • Atheros AR5B95
  • Atheros AR9382
  • what is said to be pretty well supported by gnu linux kernel (and kali) (UNTESTED!) is USB WIFI Sticks from ALFA
    • tested: the ALFA Networks AWUS036ACS / AC600 / 802.11ac, 2.4/5GHz, USB WLAN Adapter, does NOT work out of the box with Debian (free or non-free) which
      • the Edimax (Realtek RTL8187B chipset (802.11G)) does!
  • GNU Linux Debian 11 (64Bit) comes with those drivers:

      the taped pin 20 “hack”

      some cards refuse to work “airplane mode” on and can’t be switched off, taping the pin 20 helps:

  • Atheros AR9170 chipset (802.11N)
  • For Mini PCIe all cards with an Atheros chipset are supported

Wifi has always been a problem for free software users. USB Wifi cards are becoming less free. With the older 802.11G standard many USB wifi cards had free drivers and did not require non-free firmware. With 802.11N there is only one chipset on the market, from Atheros, which is completely free.

One company which specializes in free software and sells 802.11N USB wifi cards, ThinkPenguin.com, has indicated the availability of free software supported 802.11N USB wifi cards is disappearing. Solving this problem will require more demand than currently exists.

had to swap the Wifi card on both LibreBooted Lenovo x60s for Atheros ar5b95 Wireless WiFi WLAN Karte für HP g42 cq42 g62 cq62 580101-002 PCI-E Mini PCIE

(this Debian non-free package is NOT needed, here are the sources of ath9k)

then it works like a charm.

(they do not exactly fit… the original ones are “longer” thus help yourself with some non-conducting tape)

did a test setup of Trisquel 8.0 (Richard Stallman is using this! Why is it Ubuntu based (which again is Debian based)? we don’t know) on Lenovo t440 and works quiet well… except (again) the wifi (no open source drivers for the Intel Corporation Wireless 7260 (rev 83))

https://ark.intel.com/content/www/us/en/ark/products/75174/intel-wireless-n-7260.html

it is really a pain in the a… that there are so many: Board Form Factor: in this case it is a PCIe Half Mini Card/ M.2″ (whatever that means… it means it is very very small X-D more on form factors)

… now looking for an alternative to this card.

also: did not know the lenovo t440 has TWO (!) batteries. One is fixed inside the case, the other is removable and then (of course) there is the CMOS battery.

so it has 3x Batteries if you count the CMOS as well.
