Reinstalled my Lenovo Thinkpad E535 Xubuntu. Ubuntu ran before and there everything worked so it can't be due to the hardware.
My laptop works fine with LAN. At first he did not work with WLAN. Meanwhile, it works a little bit. Dropbox can synchronize the files very slowly. Firefox does not work at all "" The connection has timed out ".

After that I haba as a tip for problem solving the following.
echo "blacklist b43" | sudo tee /etc/modprobe.d/blacklist_b43.conf
Change the encryption of your Fritz box to purely WPA2-AES (CCMP), do not use outdated WPA1-TKIP encryption or mixed WPA1 / 2!
change the SSID of your Fritz box of factory setting "FRITZ! Box Fon WLAN 7360" on something useful without spaces!
Reboot.
The change named above causes Dropbox to sync very slowly. And Firefox does not load properly for the purpose of connection has timed out.
==> There's WLAN, but apparently very weak / unstable. But can't be due to my leadership. And before hats with Ubuntu also worked
Would be great if someone from the experts can help me.
Try using
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
This will do your system and update all packages
Maybe that helps
I did that and then reboot. Still does not work.

Maybe your WLAN adapter needs a proprietary driver. Look in the driver management to see if your hardware such a driver is offered for download.
Otherwise it could still be missing a firmware. If you know which name your WLAN chip has, you can search for it with a package management tool (for example, Synaptik).
A difference between the two distributions is of course the desktop. It could be that the XFCE does not use the network management program (networkmanager) correctly. Maybe there's a bug. You could try using wicd instead of networkmanager to manage network connections, here's a link to the wiki:
https://wiki.ubuntuusers.de/Wicd/
And here's another one for networkmanager:
https://wiki.ubuntuusers.de/NetworkManager/
Many thanks. Driver management, then select proprietary driver. Reboot and it works.
I'm really inexperienced with Linux with WLAN. I usually set it up at the beginning, take a bit, and then nothing changes. That's why I have little knowledge about it.
Everytime I change a system to Ubunutu, I had these WLAN problems. Just not on this laptop. That's why I was even more confused.
That there are two different desktop, I knew. But desktop is just the surface for me. And that has nothing to do with the WLAN. Apparently already.
The desktop itself has nothing to do with the WLAN. But the integration of the program Network Manager may already. Networkmanager is a command-line utility and is included in all Ubuntuware versions of the same version in the same version. The functional scope of the graphical front ends is very different. I'm using Kubuntu and had a bug in the graphical network manager frontend for KDE a couple of years ago. The problems that you had seemed to me very familiar.
I'm glad that I have an officially linuxfähiges notebook because there are no such problems with the drivers and everything is out of the box.
In my opinion, either the driver goes or not. That may not be the reason.
Bad performance and crashes sound like double-booked channel.
Look with the mobile phone and such app as "Wi-Fi Analyzer", if this may be the reason and change this if necessary
Maybe your WLAN adapter needs a proprietary driver.
He has loaded a module, a second makes no sense:
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
If you know which name your WLAN chip has, you can search for it with a package management tool (for example, Synaptik).
He also posted that:
Broadcom Inc and subsidiaries BCM4313
Otherwise it could still be missing a firmware.
Then the hardware would not work, it either works or not, but poor performance has nothing to do with the firmware.
You could try using the wicd tool to manage network connections instead of networkmanager, here
That does not change the way the hardware is addressed, so what's the point?
You have written a lot but no idea what the cause can be, not even an idea what it can't be - A useless contribution.

Super
And that has nothing to do with the WLAN. Apparently already.
No, the user interface has nothing to do with whether a hardware works, because of course, it must work without a desktop.

I admit that I'm not particularly keen to read through any log files. I'm also aware that you have more competencies in this area than me. I consider Linux as a user and have just gained my experience with Ubuntu over the years. If I can help one or the other to use Linux as an operating system, there's nothing wrong with that. I'm always in favor of simple solutions as far as they are possible and do not come around the corner with the command line. For many new Linux users that is more of a deterrent. In addition, I could help the questioner yes. I think we can cultivate the same terrain in different ways without discrediting each other.
