[SOLVED] Wifi issue during installation

[abdullahdhiab]

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

[bogdancovaciu]

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

[abdullahdhiab]

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).

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

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:

Broadcom wifi driver fails to install properly

If your Broadcom wireless adapter driver is detected as "bcma-pci-bridge" or "b43-pci-bridge", your driver has likely been installed incorrectly. Examples: Kernel driver in use: bcma-pci-bridge Kernel modules: bcma Kernel driver in use: b43-pci-bridge Kernel modules: ssb If your WiFi connection is not working correctly you will need an alternate means to connect to the internet. You can use a wired LAN connection if your computer has a wired NIC (and a connection is available). The other…

@tbg, not able to remove driver?

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.

[abdullahdhiab]

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