Need to "poke" Network Manager after boot to start wifi data transfer

UncleSlacky

In the last few weeks, I've found that my wireless connection works OK for about a minute after booting, then stops receiving data. It can be reactivated just by right-clicking on the Network Manager tray icon (not even disconnecting/reconnecting) to look at the current connections. It's a minor but annoying issue. Here is the output of inxi -GN if it helps:

Graphics:
  Device-1: Intel UHD Graphics 605 driver: i915 v: kernel 
  Device-2: Chicony USB2.0 VGA UVC WebCam type: USB driver: uvcvideo 
  Display: x11 server: X.Org 1.20.11 driver: loaded: modesetting unloaded: fbdev,vesa 
  resolution: 1920x1080~60Hz 
  OpenGL: renderer: Mesa Intel UHD Graphics 605 (GLK 3) v: 4.6 Mesa 21.1.2 
Network:
  Device-1: Realtek RTL8723BE PCIe Wireless Network Adapter driver: rtl8723be

Edit: I think I found the solution:

Create a /etc/modules-load.d/rtl8723be.conf with the following content:

options rtl8723be fwlps=0

It seems to be working so far...

Update: It only seems to work about half the time, so there might be some other factor at work here.

Still no joy, I've tried every combination of "options" in the conf file, both with and without TLP enabled, and the problem persists. It seems to be the same as this problem in the dev tracker.

Any ideas?

UncleSlacky Except that the task you are reffering to was resolved in 2017, that it didn't mention rtl8723be and that it was on older kernel versions.
It is not because some symptoms look similar that it is the same disease.

-> You shouldn't necro an old resolved task for obviously a new different issue.

kyrios I only mentioned it because of this comment under that issue:

Also possible, is that users of the rtl8723be and rtl8192ee may have these or similar issues

It seems that I made a mistake in my original attempt, the config file should (I think) be placed under /etc/modprobe.d instead (even though that directory didn't exist, so I had to create it - presumably Solus does look in that directory if it exists?).

Just in case anyone finds this thread, putting an rtl8723be.conf file in /etc/modprobe.d containing:

options rtl8723be fwlps=0

works.

Update: over the last few days it's started doing it again - maybe the issue has been corrected at the kernel level and it's conflicting with my setting? I've removed the config file & will see if that has any effect.

If anyone needs to know, the fix this time seems to be:

options rtl8723be disable_watchdog=1
