The kilpper networking connection always reports errors
How can I solve it
Hi @942892828 ,
WiFi isn’t a function of Klipper. It belongs to the operating system and Klipper never interacts with the network.
We’ll also need some more information:
According your log, you’re running a BTT CB2. Did you install the antenna?
On the Klipper side of things, it looks like you’re not even running legit Klipper:

I would switch back to mainline (GitHub - Klipper3d/klipper: Klipper is a 3d-printer firmware) if you need any more help.
Sorry, the Klipper I am currently using is a memory card that someone burned for me. They asked me to help improve the WiFi function on this basis. I only know so much information. How can I improve the WiFi function of this system based on basic information? The current problem is that when switching to another WiFi, I cannot connect. The password is correct, and after half a day, it automatically switches to the WiFi I just connected to. The distance between these two routers is the same, so there should be no signal strength issue
You’ll have to rely on command line tools for networking in Debian.
This may be a good starting point.
Debian is moving from network-manager to netplan. Last I checked klipperscreen needs network manager if you want to manage WiFi from the touch screen. I run one of my machines off an x86 (Intel) pc. The current debian server release uses netplan. Klipper screen would load and function except would not display IP address or scan for wifi.
Thank you for your reply. Your response is very accurate. It is indeed necessary to manage WiFi on the touch screen. Klipperscreen needs to configure the network connection in the system background. The installation configuration is included in the wiki webpage you sent. Is it feasible to install it according to the prompts? My level at the system level is limited, can you provide a case study prompt. I found the following command in the wiki, can I run it directly? The code is as follows:
sudo apt install
htop glances nmon sysstat
iftop nethogs bmon
mtr-tiny tcpdump tshark
httpie curl
tmux screen
iotop atop
rsync
brew install
htop glances nmon
iftop nethogs bmon
mtr tcpdump wireshark
httpie curl
tmux screen
rsync
You need to access the linux terminal on the host system. That is most commonly done via SSH. See the documentation for the OS you have installed for specific instructions.
If you in fact have a CB2 the instructions are at CB2/BIGTREETECH CB2 User Manual.pdf at master · bigtreetech/CB2 · GitHub
It is also possible to connect a HDMI display and a USB keyboard and interact directly with the CB2.
