[SOLVED] Wifi issue during installation

Manjaro team,
wifi issue seems to be related to dhcp, when i assign static ip wifi gets connected.

The reason can be because your router is not set up as a DHCP server …

it’s set as dhcp, now after installing dhcpcd wifi gets connected with auto ip.

No offense, but this thread is next to useless without some details. What kernel, desktop , and network adapter are you using. If you want help on the forum you need to learn how to provide the proper information on a help request.

Please post the output of the following commands:

hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | grep -v "Config Status" 
inxi -Fxxxz

Please post the input/outputs of all requested commands via the terminal as text, (not as pics).

Information on how to properly post hardware specs and logs:

Please format any terminal output with three backticks before and after, as shown in this picture:

Thank you for posting your outputs.

In all honesty I’m surprised your wifi adapter is working at all. Which driver are you using. Is it the broadcom-wl, or did you uninstall that driver? You have a problematic adapter/driver installed.

Here is some further info:

@tbg, not able to remove driver?

[jaroZ dhiab]# pacman -Rns broadcom-wl

If you have uninstalled the broadcom-wl driver already (or it was never installed) then I would leave it the way it is for now. If it stops working follow the directions to install the linux headers and the broadcom-wl-dkms driver.

maybe was never installed. i’ll leave it as it is while it works fine.
thanks @tbg, issue can be closed.
