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)
- it’s a solid high quality USB WIFI dongle stick known as Edimax N300
- Edimax is a company located in Taiwan and is said to support Open Source software (still needs to be confirmed)
- Edimax USB WIFI dongles are known to work on many distros mostly out of the box
- (but did so with closed source drivers!)
- “Edimax’s Taiwan and China-based R&D team consists of over 200 staff members” (src)
- (EW-7612UAn V2 802.11n Wireless Adapter [chipset: Realtek RTL8192CU])
- tested and also works on ODROID XU4 (Armbian))
- the signal strength & speed are okayish (connecting to TP-Link router)
- positive:
- (but less good & slower compared to inbuild intel7260) lspci | egrep -i –color ‘network|ethernet|wireless|wi-fi’
