7 years ago No. That is a result of enabling concurrent mode, which some people want to be able to operate as a station and an AP simultaneously. The return to the previous situation, find the line "EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE" in Makefile and comment out that line.

7 years ago Oh, I comment out that line, And I can "disable" the feature. and It works well.
When I enable this feature, the wifi adaptor won't work more than few seconds.
I restart my raspberrypi , and ...

7 years ago concurrent_mode did seem to work properly for me. I haven't extensively tested it though, I'll do so asap -hopefully in the coming days- and report back.

7 years ago hi, an update:
for me concurrent mode works stable. I downloaded a 1GB file, two times:
All together this took 22 minutes. And I have had no interruption or connection losses during all of this.
Note that I do still see a kernel warning messages during driver load and also one during unload. I'll look further into that later; they seem harmless.
My tests are done on a Beaglebone Enhanced, running our Venus OS. Kernel 4.1.15.

7 years ago With kernel 4.4.0-45-generic 64bit architeture on Ubuntu 16.04 I have the same issue, the connection is unstable with that flag enabled.

7 years ago If it does not work with CONCURRENT_MODE enabled, then disable it. Driver rtl8xxxu in newer kernels (4.9) is working with the RTL8723BU. It is highly unlikely that there will be any further development with this driver.
Hello, It's me again.
Thanks again for your programming the device driver.
I got another problem here.
I compiled the driver from the newest source code, and I found two interface:
I checkouted bc9e782 , recompiled the driver and had no this issue. Did a bug introduced by recent commit(s)??
I don't know why, maybe my usb wifi adaptor's problems ?
It's late now, I will add more information after I'm free.
Am I the only person run into this situation?
