Can't change WLAN settings

[yossariane]

Can’t change WLAN settings in any way. When I go to settings/system/network/wlan0
which is disabled now and changed to DHCP has an error.
Failed to change network settings, Unknown error, see supervisor logs. Checking the supervisor log I have this.

Some thing happens if I change to static. Doesn’t matter if I do that in GUI or CLI.
Like: ha network update wlan0 --ipv4-method static --ipv4-address 192.168.5.71/24

I found similar error in thread: Fresh install - ERROR (MainThread) [aiohttp.server] Error handling request · Issue #49009 · home-assistant/core · GitHub
but it doesn’t help.

What can I do to resolve this and have my WLAN running? Any help will be appreciated.

It’s not recommended to run any sort of server on Wifi - let alone one that will be controlling your smart home.

[yossariane]

I don’t want to run any server or anything else on HA. Why do you think I want to do that? Do you see that somewhere in my log?

[Neil_Brownlee]

I think you misunderstand - HA is a server of sorts - anyway it’s not recommended. Wired all the way for this sort of application.

[yossariane]

Misunderstandings both way I want to resolve my other problem with ESPHome.

ESPHome and first new device offline, can't connect

New HA on Raspberry pi4, new device is constantly offline. Setting up new device is completed with no problem except when trying to connect give me message Configuration created but unable to detect the device on the network. After checking on line log it shows INFO Starting log output from esp1.local using esphome API WARNING Can’t connect to ESPHome API for esp1.local: Error resolving IP address: [Errno -5] No address associated with hostname INFO Trying to reconnect to esp1.local in t…

I think that I resolve it with setting WLAN. After I disabled WLAN. But now when I want to enable other esp I have same symptoms. That is reason way I want to enable WLAN.

[yossariane]

The problem is resolved by himself. I have tried many times and always have some errors. Just now, one more try and puff. It changes both static and DHCP

[Guggu]

I have done this for years. Never had a problem. I have yet to find a private home needing so much WiFi bandwidth that it could not be supported via a standard WLAN

[Neil_Brownlee]

Ask a PS5 to download a 50GB game and watch your latency drop…

I have the same bug, how is this not fixed yet? And to the complainers, why are you even running a “server” if you dont have failsave in mind?

I have the same bug

Hi!
Also had some troubles with connecting my raspberry pi 4 with home office to my network via WLAN.
Finally I created USB stick on my Mac Book named ‘CONFIG’ that contained on folder ‘network’ with a file ‘my-network’ containing the following:

[connection]
id=my-wifi
uuid=b6e4e249-1c14-420c-bf6f-b1f6e2166022
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=YOUR_WIFI_NAME

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=YOUR_WIFI_PASSWORD

[ipv4]
method=auto

[ipv6]
addr-gen-mode=stable-privacy
method=auto

Of course password and ssid need to be changed.
Shut off home assistant, plug in the USB stick an start it up (w/o ethernet cable) - worked out fine, connected via WLAN!
