Package: firmware-realtek
Version: 20210315-3
Severity: important

Dear Maintainer,

I installed Debian stable "bullseye" on my Lenovo T440S equiped with a Realtek 8192EE 802.11n PCI wirelesscard.

As explained on the wiki, I installed firmware-realtek to use it and connect to my WiFi home network and use a Bluetooth mouse.

As a result, I managed to access the available wireless networks and connect to my own one. I also managed to connect and use my Buletooth mouse.

But once connected, I encounter a loss of my WiFi connection without being able to identify an event causing this.

The result of this loss is:
* I can't list any wireless network.
* In connman, but this is also the case with network-manager provided with Gnome as a default, the card appears to run correctly as I can activate or deactivate it. Doing so has no effect.
* In connman, my BT mouse is not visible anymore wherease it is still usable.
* In the Gnome tray menu, the WiFi icon is grayed. No network is available.
* In the Gnome tray menu, my BT mouse is visible.
* If I try to list the wireless networks available, the system keeps searching in vain.
* The only mean to get the connection back identified so far is to reboot. This is quite painfull.

My WiFi router is configured to use WPA and WPA2 mixed.

I tried to deactivate the power management but this had no effect.
root@uranus:~# iwconfig wlp3s0 power off

I also tried to add options, still no effect.
root@uranus:~# cat /etc/modprobe.d/rtl8192ee.conf 
options rtl8192ee ips=N fwlps=N

Here is my current state, as I plugged my cable to continue working:

It seems this card is known to have issues with all Linux distros, but as I couldn't find a bug report describing this issue, here it is.

Many thanks for the great work, and thanks in advance for the help.
