** Description changed:
Ubuntu 20.04.01 LTS (newly installed)
(Moved that device from windows 10, didnt had issue in it)
HP 15T-au000 device.

controller
Kernel driver in use: r8169
Kernel modules: r8169
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe
Wireless Network Adapter
DeviceName: Realtek Sanji2 RTL8723BE b/g/n 1x1 + BT 4 LE PCIe+USB M.2

Kernel driver in use: rtl8723be
Kernel modules: rtl8723be
Wi-Fi key is correct (i can use internet to visit sites, watch videos in
youtube etc) however randomly disconnect and appear window to re-connect
(sometimes constantly disconnect)
No network related change has made (IPv6 disabled through settings)
Only one SSID is in use: Dialog 4G
I ran `journalctl --follow` and below is the log. let me know if
required to provide further details
+
+
+ ~Updated~
+
+ There also `PCIe Bus Error: severity=Corrected, type=Physical Layer` occur
due that wifi card - RTL8723BE
+ It usually appear when boot the device (before login screen) and currently i
surpressed that issue by adding `pci=noaer` to grub (alternative pci=nomsi)
+
+ I found https://github.com/rtlwifi-linux/rtlwifi_new and
+ https://github.com/silenoth/rtlwifi_new-extended it contain 'RTL8723BE'
+ however i found most people use them due wifi card does not display or
+ unable connect but i dont have such issue and users have reported
+ installation issues then didnt consider to put to my machine.
