I have been installing Leap 42.3 on an HP desktop with the Realtek RTL8723BE wi-fi chip and hit a number of problems. Initially it was disconnecting after a while and I used a tip from Google about adding
options rtl8723be fwlps=0
This solved the problem of the connection going down but a new problem arose: a periodically slow connection.
wlan0 IEEE 802.11bgn ESSID:"BTHub5-265F" Mode:Managed Frequency:2.462 GHz Access Point: D4:63:FE:07:25:69 Bit Rate=72.2 Mb/s Tx-Power=20 dBm Retry short limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:8 Missed beacon:0
Comparison with other devices on the network showed that their Bit Rate was 1 Mb/s [but when I got home I found that my laptop, with an an Atheros chip using the ath9k driver, showed 72.2Mb/s at home as opposed to 1 Mb/s at my friend’s house].
So I tried to reduce the Bit Rate with
iwconfig wlan0 rate 40M auto
This appeared to work for one session but has not worked since.
I did wonder about trying
iwconfig wlan0 rate 1M auto
as that was the rate that other devices were showing at my friend’s house but did not as the iwconfig did not appear to have any effect anyhow.
13.692842] rtl8723be: Using firmware rtlwifi/rtl8723befw.bin 13.693674] ieee80211 phy0: Selected rate control algorithm 'rtl_rc' 13.694439] rtlwifi: rtlwifi: wireless switch is on
but I can only find questions and no answers to how to change the rate control algorithm, if that is the way forward.
Further enquiries led to ifcfg-wlan0 which is created by wpa_supplicant and contained the line
However I could find no documentation for it suggesting whether this was a way forward for managing the occasional slowdowns.
NB during the installation wicked was used to manage the network; as it was also recommended in one post as better for dealing with the first problem, I have not tried NetworkManager.
Any advice/assistance gratefully received.
