MT7921K not detected #44

Closed gcastle2007 closed 1 year ago

gcastle2007 commented 1 year ago

Hello,

I assembled Wlan PI M4 with Mediatek MT7921K. I have message "NO WI-FI ADAPTER" on display. I use image image_v3.1.3-2023-07-11-wlanpi-os.zip

Please fix it.

Deafult login/password wlanpi/wlanpi don't work.

jiribrejcha commented 1 year ago

I've just tested M4 with the 3.1.3 image and everything is working fine. So it shouldn't be a systemic issue.

Default credentials are working fine too. Have you SSH'd in? Did you get the prompt to change default password to your own?

Did Mediatek MT7921K work fine for you on the 3.1.2 image?

gcastle2007 commented 1 year ago

No, MR7921K don't work on 3.1.2 also. login/password wlanpi/wlanpi also don't work on image image_v3.1.2-2023-02-04-wlanpi-os.zip I made fresh flash card over Balena Ether and login over ssh over ethernet on first boot.

jiribrejcha commented 1 year ago

Are you specifying the username in your ssh command?

ssh wlanpi@192.168.2.14

(replace the IP address with your WLAN Pi’s)

gcastle2007 commented 1 year ago

I use putty. I reading guide https://userguide.wlanpi.com/wlan-pi-os/faq/default-password

gcastle2007 commented 1 year ago

I also change hash in /etc/shadow to hash what i know password. But I message "access denied" in putty and "permission denied" in ubuntu.

jolla commented 1 year ago

Not able to reproduce on this end. Are you sure hitting the right IP?

@jiribrejcha on a fresh 3.1.3 image - same problem. any suggestions how to fix mt7921k on wlanpi m4?

Please provide the output of dmesg | grep pcie

You should see something like this

@gcastle2007, can you please try to use a different SSH client? It sounds like it might perhaps some settings in Putty.

gcastle2007 commented 1 year ago

@jiribrejcha , I used device of @nimbo78. I didn't know cm4 had emmc on board :)

Based on this message, it looks like either you have a bad MT7921K or MCUzone board.

[ 9.238486] brcm-pcie fd500000.pcie: link down

Do you have a different m.2 Wi-Fi module your can try in the m.2 slot? Also, I would recommend picking up the newer mt7922 Wi-Fi module, it supports 160MHz channels and so far has proved to be more stable than the 7921K has been.

@jolla some intel ax200\ax210 is ok for test purpose?

jolla commented 1 year ago

Yes

Yes, unfortunately it looks like the issue is a hardware issue with the MCUzone board. Perhaps a pin is bent or damaged on the m.2 socket. You'll likely need to get a replacement MCUzone board.

josuhr commented 1 year ago

Hey folks - having a similar issue here with a Comfast CF-953AX / MT7921au - seeing the "No Wi-Fi Adapter" message, but in my case the pcie link is up and I see the adapter in the list of USB devices as "MediaTek Inc. Wireless_Device". Any thoughts?

I feel like I might be missing something obvious from Adrian G's killer guide.

jolla commented 1 year ago

Since your issue is with USB Wi-Fi modules this would be a separate issue, I've created a separate issue to track it

nimbo78 commented 1 year ago

well, that was HW issue :) The damper between the CM4 and the expansion card is too thick and the contact between the CM4 and the expansion card was lost in several places. So I just threw away the damper rings and it works like a charm. Sorry to bother you
