Odroid C1+ | Issue to setup WLAN device

Troubleshooting
1

Hi,
to make a long story short. I fiddling around with a lot USB Wireless adapters to get it on work with a C1+ and DietPi.
No one will work on C1+ with DietPi. To be sure, tested all adapters on Win 7 (64bit), they all work well.
Most of them have manufacturer driver for Windows, Mac and Linux.

USB Wireless adapters are:

  • … and some more …



But, to make it simple, lets concentrate on Edimax EW-7612UAn V2 with Realtek Chipset RTL8192SU.

HardKernel said:

We’ve supported below WiFi modules / chipsets.

Wifi module 4: Ralink RT5572 (148F:5572)
Wifi module 3: Realtek RTL8188CUS (0BDA:8176)
Wifi module 2: Realtek RTL8191SU (0BDA:8172)
Wifi module 1/0: Ralink RT5370 (148F:5370)

A few other chipsets might work. But we couldn’t test every them.

  • Tested with C1+ and HardKernels Ubuntu 14.04 (v1.6) with Desktop and Network-Manager
    :arrow_right: * it works out-of-the-box in all offered modes (WiFi client and P2P-device).
  • Tested with Raspberry Pi B+| DietPi V116
root@RPi-B-Plus-Test:~# uname -a
Linux RPi-B-Plus-Test 4.1.21+ #872 Wed Apr 6 17:27:13 BST 2016 armv6l GNU/Linux

:arrow_right: * it works as managed (WiFi client) and AP ( WiFi HotSpot and Tor WiFi Hotspot)

  • Tested with oDroid-C1+ | DietPi V116
root@oDroid-C1_plus-test:~# uname -a
Linux oDroid-C1_plus-test 3.10.80 #1 SMP PREEMPT Sun Mar 13 15:50:53 CET 2016 armv7l GNU/Linux

:exclamation: - WiFi scan with " dietpi-config " and " iwlist wlan0 scan " works, but it will impossible to connect to the network (Router WiFi Channel 7)
:exclamation: - To be sure, also tested WiFi HotSpot and Tor WiFi Hotspot, result is equal. No success.

I’m really frustrated, spend 20 hours for installing, testing, google around with no working result.
Don’t think, it’s a issue on DietPi itself.
Most of the adapters works with DietPi RPi image as WiFi client, but only Realtek Chipset RTL8192SU works with hostapd as WiFi HotSpot.
As well checked via apt all installed firmware on Odroid C1+. It’s seem to be okay.

firmware-atheros ist schon die neueste Version.
firmware-brcm80211 ist schon die neueste Version.
firmware-ralink ist schon die neueste Version.
firmware-realtek ist schon die neueste Version.

Truly strange. Is where any help? Thanks in advance.

Hi,

have to open a github ticket. You can read the story here, but be warned, it’s long:
DietPi-System | C1+ | Issue to setup WLAN device #273

Upshot:

  • @Fourdee never give up, he did a great job and finally he get it on work in DietPi v116 (testing). :smiley:


  • as well @Fourdee implement same new features, e.g. to have wired and wireless connection at the same time. But this is at the moment not perfect, but very useful. (work in process)



Results of “iperf” tests as WiFi client:

  • Edimax EW-7612UAn V2 -

  • Works as WiFi HotSpot

  • Tor WiFi Hotspot

  • and WiFi client:

Conclusion:

  • use a wired connection wherever it’s possible.

  • WiFi HotSpot and Tor WiFi Hotspot are nice features, if your Wireless adapters support this.

  • @Fourdee do a great job, best support I have ever seen, DietPi is a awesome minimal image. Thanks a lot!

  • as well thanks to @rhkean

Awesome – you would happen to have a copy of dmesg before & after? It would be cool for any sort of automation during network setup/re-configure…

RealTek has been a pain for many, many builds of Ubuntu, Deb, etc on different architectures – sometimes apt-get install linux-firmware works, sometimes it doesn’t.

Kuods, though!
