[SOLVED] Problem with HP Pavilion Wireless Network Device

My laptop is a refurbished HP Pavilion 15-au030nr. I have installed Arch Linux alongside Windows 10, which came with the computer. I am using GRUB as my boot manager. My system is up to date as of posting this (as per sudo pacman -Syu). I have noticed that my wireless network device consistently performs better on the Windows 10 partition. For instance, I did a speed test last night (https://fast.com/), and the difference between Windows and Arch was 26 Mbps and 15 Mbps on one network, and 5 Mbps and 800 Kbps on another. On top of that, its range seems to be more restricted on Arch Linux. Where I am at, you can usually detect up to 20 different networks at a time. On Arch Linux, my laptop can only detect 3, if that (using both wifi-menu and iwlist <device> scan). Half the time, it can barely detect my router when it is only several feet away (admittedly, it is a rather poor router).

My wireless network driver is an RTL8723BE. I followed the instruction on the Arch Linux wiki to install my driver (https://wiki.archlinux.org/index.php/Wi … Frtl8723be). If I recall correctly, the driver was already installed when I tried to install it via pacman.

Also, it should be noted that I have experienced some trouble with one of my PCIe ports. On bootup, this message would sporadically spam any TTY session I tried to use:

pcie 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e8(Receiver ID)
pcie 0000:00:1d.0:   device [8086:9d1b] error status/mask=00000001/000020000
pcie 0000:00:1d.0:   [ 0] Receiver Error

(these messages were copied by hand)

I followed the instructions from this forum post to fix it: https://bbs.archlinux.org/viewtopic.php?id=56940

The performance of my wireless network adapter seems to be the same with and without the aforementioned fix. Plus, the PCIe device associated with the error is not the same as my wireless network device (see lspci -c output below).

Additionally -- although I doubt they are of any importance -- these suspicious messages appear on boot:

MSFT0101:00: failed to claim resource -1
acpi MSFT0101:00: platform device creation failed: -16
. . .

Re: [SOLVED] Problem with HP Pavilion Wireless Network Device

Some newer HP computers with rtl8723be wifi are known to use just one antenna, we can try some module parameters to see if one performs better than the default setting
Lets see what the default setting gets

iwlist scan | egrep -i 'ssid|quality

Then we can unload the module and reload with a different setting to try

sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=1
iwlist scan | egrep -i 'ssid|quality

Then we can try the second option and compare results

sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=2
iwlist scan | egrep -i 'ssid|quality

Did one setting work better than the other 2?

Re: [SOLVED] Problem with HP Pavilion Wireless Network Device

Thanks jeremy31! Your solution fixed my problem. I tried ant_sel=1, and the difference was night and day compared to the default options and ant_sel=2. I edited /etc/modprobe.d/rtl8723be.conf and changed...

options rtl8723be fwlps=0

to...

options rtl8723be fwlps=0 ant_sel=1

and my network device behaved as desired after rebooting.
