That value means that the signal strength is way too low. One other
possibility is that the chip has retained the setting and is not
obeying the antenna number command. To check that, create a file (as
root) named /etc/modprobe.d/50-r8723bs.conf, and add a single line
containing "options r8723bs rtw_ant_num=2" (without the quotation
marks). After that file is ready, then do a cold boot so that the chip
has been power cycled. Finally, redo the signal test. Note: If your
patch is applied, the above will not work!
I've applied my patch and got the following results (btw good idea with
the cold boot!):
***FILE CREATED***
options rtl8723bs rtw_ant_num=1
***POWEROFF + 2 MINUTES WAITING***
***REBOOT + COMMAND***
sudo iw dev wlan0 scan | egrep "SSID|signal"
-> Desk

SSID: Gonzales
signal: -63.00 dBm

ccepted. Even if it had been correctly done, I would have NACKed it.
Sry, would you reformulate this, please? I just can't
understand/determine what the word "NACKed" means in this situation
(Neither google or the raw translation helps me).
Thank you,
Simon

Use the following command to get the baseline values:
Done - aand nothing changes (The access point has a strength of -60dB

Yay - sorry for that.

In dmesg
Yep, too late. I've already installed the necessary firmware-files.
But I didn't wrote it, because the WiFi test wasn't performed until yet.
o the work to get the driver into the condition necessary for it to
be in the regular tree.
Did my patch made it?
Your patch was not in the correct format to be accepted. Even if it
had been correctly done, I would have NACKed it. Given the location of
the driver, the name is what it should be. Once you, or someone else,
has done the many hours to put that Realtek crap into proper kernel
form, then it could be placed in the normal wireless tree and given
the name rtl8723bs.
