Ask for RTL8822CE AP and Station mixed mode

[kearney]

what happen

In most case, our network device work in Station mode. If I want it to make a hotspot(AP mode). It will turn itself from Station into AP mode. So it means they are confilct on RTL8822CE.

But when I update win11 for a few times, I find the conflict solved on RTL8822CE. It can work in both model at the same time on win 11. But I upadte my Manjaro and it seems nothing changed.

advice

1. Add new mixed mode.
2. Let the hotspot button shown at normal situation. Not only shown when close wifi. The search panel is too big to block the hotspot button.

3. Hotspot manage tool.
   In the past, we need to edit file directly to config hotspot. Now we can config SSID name and pwd in setting. Maybe we can do more in the setting. Like turn on and off, see and block user…

Now I can not find the hotspot manage in system setting…

[kearney]

I got two ways to crate AP(hotspot), but both can not connect to the Internet.

1. networkmanage panel in system tray

config file in ~/.config/plasma-nm

How to create a hotspot on manjaro?

I test some DE and I choose KDE Plasma finally. There is an easy way to open a hotspot. [iKDE example] config file in /home/kearney/.config/plasma-nm https://unix.stackexchange.com/questions/136169/how-do-i-edit-the-hotspot-configuration-for-network-manager

2. system setting - Connection

How To Create WLAN Hotspot on Ubuntu with KDE Plasma 5 - SalesJobInfo

So the advice 3 has been reach a long time. The Mixed model and panel problem still there

[kearney]

hotspot no Internet connection

linux-wifi-hotspot

https://wiki.archlinux.org/title/Software_access_point

I try linux-wifi-hotspot and got the reason(GUI will not show reason so use terminal) - my wifi adapter problem.

$ sudo create_ap wlp1s0 eth0 MyAccessPoint MyPassPhrase
ERROR: Your adapter can not be a station (i.e. be connected) and an AP at the same time

plasma-nm

https://bugs.kde.org/show_bug.cgi?id=452449

this happens because when you’re using WiFi to receive a connection, you can’t also be using WiFi to generate another one

conclusion

At the beginning, I know the wireless card can not work in same mode cause only one road. But as time goes, wirelss card gets more roads that it can work in mixed mode. I test RTL8822CE on win10/11. It can not in work both mode. But last update on win11, it suddenly can. I can not record it again for I uninstall win11 totally. I have download the win11 and install. Test shows that RTL8822ce could work at mixed mode(ST+AP).

lakinduakash/linux-wifi-hotspot Doesn’t work with rtl8822be. #175 . So the point is that the linux driver has not reach yet.
