Generic RTL8723B Wifi/BT Dongle

Tried a NoName RTL8723B Wifi/BT Dongle, but without success.

dmesg log says tell Sorgelig about it :-)

Loads rtl8723bu_nic.bin but direct firmware load afterwards fails with error -2 (rtl_bt/rtl8723b_config.bin).

Thanks for reading ...

I went with a $5 wifi dongle and it worked fine using the setup scripts.

Well, it seems i'm not very lucky with those sticks.

First tried a D-Link DWA-131 A1G i had in my hardware pile. Not recognized.

Then a D-Link DWA-171 C1G (which could/should work, but not out of the box, as the WiFi-Wiki states). Recognized as memory-stick, but not as Wifi.

And at last a "PowerON" BT/Wifi combo-stick. Recognized, but failed while loading drivers.

Besides the dongle official name it's VERY important to match the HW revision as many manufacturers sell completely different HW under the same name and appearance. Sometime even chipset is different.

That's a sad fact and i coudn't find one seller who specifies the HW revision in his shop ...

This is the difficulty with the wifi modules. I have 3 modules that were ostensibly the same as the ones listed (just happened to have them lying around), and they all worked, but were very slow. I just opted to setup a wifi-to-ethernet bridge instead on a spare raspberry pi, and works great now. That's an alternative, I have other devices hooked up to it via a switch which gets around the issue.

Could find a TP-Link TL-WN823N v2 stick and managed to get in working (although there are "Path_A RX/QK" fails in the log, whatever that means).
And yes, it's sloooooow (500 to 700 kB/s) compared to cable (~ 5 MBit).

Now i've only one annoyance left for my perfect Mister config: Find some way to autostart "loadkeys de" :-)
There is no rc.local, no cron, no vconsole.conf. I'm out of ideas ...

MiSTer uses classic init.d startup folder where you can place startup scripts according to init.d standard.
