Hi all,
I have attempted to solve this issue by following the wiki here. Although I lowered the rate and txpower as well as set RTS and fragmentation thresholds, the problem still persists. The following is the lspci -v output for my wireless adaptor.
04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter
Subsystem: Lenovo Device b736
Flags: bus master, fast devsel, latency 0, IRQ 40
I/O ports at 1000 [size=256]
Memory at f0800000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: rtl8723be
Kernel modules: rtl8723be
Is there a way to fix this?
Thank you very much!

What are you using to manage the connection? Please paste the systemctl status output and the output of `uname -a`?

Hi Jason,
I am using network manager and on the newest kernel. However, the problem still persists when I switched to netctl.
Here is the output:

Thank you very much!

You should not start wpa-supplicant as a service when using NetworkManager. NetworkManager will spawn a wpa-supplicant daemon when it needs it. The wpa-suplicant service spawns a wpa-supplicant daemon that conflicts with the one that NetworkManager tries to launch.

Hi,
Thank you very much! I just stopped & disabled the service. I will close this post if the problem stop reoccurring.

Hi,
I am sorry to be back again . I have tried "sudo systemctl stop wpa_supplicant.service" but when I check the status with systemd again, the service is still running. If I try to remove wpa_supplicant, pacman tells me networkmanager actually depends on this service. What should I do to stop this service?
Thanks a lot!

The service might be started by NetworkManager. I don't use NetworkManager, so I cannot check. But, if it does, the systemctl status output will show the wpa_supplicant service as a branch of the tree under the NetworkManager service.
