<br>
I have been installing Linux on an HP desktop with the Realtek RTL8723BE wi-fi<br>
chip and hit a number of problems. Initially it was disconnecting after a<br>
while and I used a tip from Google about adding<br>
<br>
options rtl8723be fwlps=0<br>
<br>
to /etc/modprobe.d/rtl8723be.<wbr>conf.<br>
<br>
This solved the problem of the connection going down but a new problem arose:<br>
a periodically slow connection.<br>
<br>
iwconfig produced<br>
<br>
wlan0 IEEE 802.11bgn ESSID:"BTHub5-265F"<br>
Mode:Managed Frequency:2.462 GHz Access Point: D4:63:FE:07:25:69<br>
Bit Rate=72.2 Mb/s Tx-Power=20 dBm<br>
Retry short limit:7 RTS thr=2347 B Fragment thr:off<br>
Encryption key:off<br>
Power Management:off<br>
Link Quality=36/70 Signal level=-74 dBm<br>
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0<br>
Tx excessive retries:0 Invalid misc:8 Missed beacon:0<br>
<br>
Comparison with other devices on the network showed that their Bit Rate was 1<br>
Mb/s [but when I got home I found that my laptop, with an an Atheros chip<br>
using the ath9k driver, showed 72.2Mb/s at home as opposed to 1 Mb/s at my<br>
friend’s house].<br>
<br>
So I tried to reduce the Bit Rate with<br>
<br>
iwconfig wlan0 rate 40M auto<br>
<br>
This appeared to work for one session but has not worked since.<br>
<br>
I did wonder about trying<br>
<br>
iwconfig wlan0 rate 1M auto<br>
<br>
as that was the rate that other devices were showing at my friend’s house but<br>
did not as the iwconfig did not appear to have any effect anyhow.<br>
<br>
demesg showed<br>
<br>
[ 13.692842] rtl8723be: Using firmware rtlwifi/rtl8723befw.bin<br>
[ 13.693674] ieee80211 phy0: Selected rate control algorithm 'rtl_rc'<br>
[ 13.694439] rtlwifi: rtlwifi: wireless switch is on<br>
<br>
but I can only find questions and no answers to how to change the rate control<br>
algorithm, if that is the way forward.<br>
<br>
Further enquiries led to ifcfg-wlan0 which is created by wpa_supplicant and<br>
contained the line<br>
<br>
WIRELESS_BITRATE=''auto"<br>
<br>
However I could find no documentation for it suggesting whether this was a way<br>
forward for managing the occasional slowdowns.<br>
<br>
NB during the installation wicked was used to manage the network; as it was<br>
also recommended in one post as better for dealing with the first problem, I<br>
have not tried NetworkManager.<br>
<br>
Any advice/assistance gratefully received.<br>
