hello everyone I have a problem after restoring the openwrt firmware after a brick, the wifi on the network menu is not present and the leds on the 2.4ghz and 5ghz router on the router are always off. how can i solve it. thanks
Hi idris83,
have you tried to restore the stock firmware from vendor and then reupload openwrt?
Try your WiFi with the stock firmware and the try again with openwrt.
Greetings
Peter
thanks for the answer is already something that I have tried, sign serial and then openwrt but Wi-Fi does not work
So, you installed a recent OpenWrt release, discarding all previous configuration, but wifi does not work and you cannot activate it, am I right?
Can you describe this a bit more?
Probably you've overwritten your art partition which contains device specific calibration data for your wifi hw.
no I can't activate it, it's not even in the network menu.
of steps before I could install the new firmware, I did a lot of tests but a few times I did things I didn't even know what I was doing,
What is in your "/etc/config/wifi" file?
it says"not found"....
Post the output of the command dmesg with the preformed text function </> and we can tell you more about your real problem.
sorry I can't post the screen, how can I do it? thanks
Sorry, I meant "/etc/config/wireless".
" Permission denied" thanks
Since it's not an executable file, trying to run /etc/config/wireless (by typing only its name) is an error. The cat command is useful to open a file and print the contents. Run cat /etc/config/wireless
To post text from the router, copy it out of the window and paste it into the forum then put ` marks (key at the far top left of most keyboards, next to the esc key) around it. Properly done the text will appear in typewriter font in the preview on the right side of the forum screen.
