I was using the edimax nano adaprtor, and was disconected from the device often.
In fact the only way I could establish wifi communication was by connecting the ethernet cable and leave it hanging. I guess it add antena to the board.
I then got out and bought the WN722N Ver: 1.9
Very cheap and had a standard wifi antena.
fitting it between my beagle bone black and the OSBO board wasn’t easy, yet it works.
Now I don’t get disconnected , at all.
I didn’t need to add any drivers as it seems the image allready supprted the ath9k-htc module.
By te way linux fans can also use this wifi adaptor to achive miracast using the miraclecast project.
Thanks for the update. Indeed WiFi on OSBo hasn’t been very reliable. Using the TP-Link adapter is definitely a good work-around. I heard that the WiFi issue is likely caused by the driver. We will be making a updated OSBo SD card image soon and hopefully the latest Unbutu OS will solve the driver issue.
