No Wi-Fi adapter found

Hi guys!

I’m really new to fedora and I really like the project but I can’t connect to the wifi!

I just installed it and when i go into the wifi settings I receive the “No Wifi adapter found” I can’t find anything online to help so I hope the community will be able too.

Here are a few screenshots to help troubleshoot :

I appreciate any kind of help

Hello @kwams and welcome to ask :fedora:

Please post the output of lspci -nn and try to show all the output that may be network adapter related. The part that says Network controller may be for the ethernet adapter and there should be more that shows something like

04:00.0 Network controller [0280]: Qualcomm Atheros AR93xx Wireless Network Adapter [168c:0030] (rev 01)
06:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)

There also is a possibility, no matter how slight, that secure boot may prevent loading the modules.

Try lsmod | grep rtw to see if any modules are loading for that realtek adapter and report the results.

Hey @computersavvy , Nothing shows up with lsmod | grep rtw

Also, there is no other network related input but here is the full screenshot

Thank You so much for help!

I disabled fast boot and secure boot and no results yet

Please try some way to get what you see on the screen to a text file that can then be uploaded as text into your posts. There are several commands that will have several screens of output and screenshots are not ideal for us to read, analyze, and comment upon the posts.

The first of this sort is dmesg, of which the entire output would be useful. It could be saved to a file with dmesg > dmesg.txt then the file just created could be put onto a usb, transferred to another PC (the one you are using to post) and the content then pasted into the post using the </> preformatted text button on the toolbar just above your text entry to retain the original display format.

The output of lsmod | grep rtw is also useful.

Got it for the scrrenshots.

I can’t put the whole output of dmseg because of the length being over the limit.

Here is a link to the text file : dmesg.txt - Google Drive

Thank you so much for your help

Also, lsmod | grep rtw does not output anything.

What should I look for in the dmseg output ? Do you want me to share only errors?

Does wifi work when you boot a Fedora or other distro Live USB? It is often helpful to have other distro installers when troubleshooting hardware issues. I suggest live images with pre-installed hw-probe: Debian, ArcoLinux or OpenMandriva. These provide
the hw-probe tool, which (assuming networking works) will upload a sanitized snapshot of your hardware configuration. This helps build a database of hardware and drivers that work in linux.

sudo -E hw-probe -all -upload
Probe for hardware ... Ok
Reading logs ... Ok
Uploaded to DB, Thank you!

Probe URL: https://linux-hardware.org/?probe=XXXXXXXXXX

The “Network controller” line shows a Realtek “10ec:b852”, but there are multiple wifi chips with this ID. The output of sudo hwinfo show give something like:

Hey @gnwiii thanks for your help, here is the output for hw-probe :

maybe that would help

tried again, couldn’t get it to work. Even after installing everything, same error

Says: " We have not found a driver for the device in any Linux kernel versions up to 6.0 (according to the LKDDb) or known additional packages."

Many laptops have wifi on a removable card, so you may be able to substitute another wifi card. There are many high-quality wifi cards pulled from systems only a few years old when businesses upgraded to newer wifi standards. There is often a years or so lag before a new wifi card gets a
linux driver, so for many linux users an older card works well.

I concur with George.
Someone a short time back purchased an intel wifi card for their laptop to replace a realtek and was very happy with the intel.

In fact here is an intel AX210 on amazon that is <$30 and is supported by linux
