@OCActivated What is your laptop model ?

Lenovo G50-30. Also, I can't open the terminal by pressing Ctrl+Alt+T or Alt+F2 in setup.

Indeed the solution provided by @anubthomas seems to be the right one.

At boot, when you see the grub screen, quickly press "e".
Write "module_blacklist=ideapad-laptop" after cros_debug and then F10 to boot.
Verify if you have wifi.

If you have, finish the setup, open cros shell and run "sudo edit-grub-config" to add the "module_blacklist=ideapad-laptop" in a persistent way.

Nope. I typed "module_blacklist=ideapad-laptop" after "cros_debug" but it didn't worked. I can only access internet by using ethernet cable. Also I'm getting error on the screen like this:

Ah great, since you can login, could you send me a dmesg (taken after a reboot):
Open cros shell
Type "dmesg > ~/Downloads/dmesg.txt"
And post here the dmesg.txt file from your downloads directory.

from brunch.

It says "ERROR : unknown option: > ~/Downloads/dmesg.txt".

I think you were not completely in cros shell, to open cros shell press CTRL-ALT-T and type "shell" at the invite.
Once you are there, run "dmesg > ~/Downloads/dmesg.txt"

from brunch.

Okay. Here is the dmesg.
dmesg.txt

Could you try to add "options=broadcom_wl" to the kernel command line ?

Go to cros shell again:

• run "sudo edit-grub-config"
• add "options=broadcom_wl" after cros_debug
• Press CTRL-X to quit and y to save when requested

Reboot your laptop

from brunch.

Yeah, it worked! I'm now successfully connected to my network. But I have 2 more problems. Shall I continue the issue here or open a new issue?

from brunch.

Yes, you can continue here, what are the other issues ?

I got an error, as it appears in the photo I took. I cannot open Google Play Store and other Google Play Services.

Nope. I typed "module_blacklist=ideapad-laptop" after "cros_debug" but it didn't worked. I can only access internet by using ethernet cable. Also I'm getting error on the screen like this:

For the android apps issue, could you try to reset google sync:

And then do a powerwash.

Thank you so much. I did a powerwash and now I can access to Google Play Store. 👍
