[RTL8723AE] Driver problems

[RTL8723AE] Driver problems

[André Martins]

Hi!
This is a copy I've sent to Larry Finger and his bot told me to sent to 
this e-mail address instead.
Basically I've bought a computer with the 8723ae card and unfortunately the
wireless connection is really bad. Although I'm a last year student on 
MSc in
computers and telematics engineering I don't have any skills what so 
ever on
kernel's source code. Thus, I want to ask you if you could help me out 
and tell
me where to begin to fix this and create a great rtl8723ae driver for 
Linux. I
could help you with the tests what whatever I could. The main problem 
with this
card is the connection on my university, it's always dropping and 
impossible to
have a stable connection. On my house I'm a few meters way of my AP and 
the link
quality is either on 38/70 or 70/70.
Since you take the time to read this e-mail I thank you already.
Thanks,
André Martins

Hi André,

start with googling for "linux wlan troubleshooting".
Use latest kernel wifi source code:
https://git.kernel.org/cgit/linux/kernel/git/linville/wireless-next.git/

If you can compile kernel by your self, then you can do some changes on
kernel. See how driver works, add "printk("%s:%i\ņ", __func__,
__LINE__);" every where and monitore dmesg. The driver is located here:
linux/drivers/net/wireless/rtlwifi/rtl8723ae

If you wont to help with this driver, do not fear to brake you kernel ;)

André,

I am sure you understand why I do not answer requests for debugging from E-mail 
that is sent to me alone.

Does the card work at your house? You need to be as clear as possible in what 
you write.

What are the details at the University? How far are you from the AP there? What 
kind of encryption is used (WPA, WPA2, etc.)? How much interference is there on 
the channel used? Posting the output of 'sudo /usr/sbin/iw wlan0 scan' will 
answer that.

For debugging, please try the following commands:

sudo /sbin/modprobe -rv rtl8187ae
sudo /sbin/modprobe -v rtl8723ae ips=0

Does that help?

When the disconnects happen, what is the indication in the output of dmesg?

Finally, we need to check your firmware. The md5sum values for the fw on my 
system are

ce50dfe07dbb1bfe9e14bdb315a4b28a  /lib/firmware/rtlwifi/rtl8723fw_B.bin
69ccaffbe94cc0ef1b89c25290e19b2e  /lib/firmware/rtlwifi/rtl8723fw.bin

 From the dmesg output, which one is being used on your system?
