What is the password ?

nakulttt commented 3 years ago

I have tried not working , but please can you send image while adding "options=broadcom_wl" in developer window

ecaron commented 3 years ago

@Nakul-TK, please close #1026 - duplicate tickets just slow down the speed that you get support. Also I'd suggest reading https://github.com/kossnocorp/etiquette - support on this channel is free, 9 posts in 8 hours is a lot of noise. People tend to prefer one really well written comment versus 8 one-liners.

If you're being asked for a root password on your machine but you don't remember setting it, then you should probably Powerwash your machine and try again (CTRL+ALT+SHIFT+R at the login screen). Sidenote: Powerwashing, as you may know, will wipe all data from your machine & put it back in factory reset state as if you just installed Brunch for the first time

Once you can successfully open crosh, then shell, then sudo, the instructions at https://github.com/sebanc/brunch#from-chromeos talk you through what you need.

nakulttt commented 3 years ago

I havd done that but WiFi is not working. We can do anything with dmesg.txt ?

nakulttt commented 3 years ago

dmesg.txt I got this as output

Please help me

Try using the password "chrome"

nakulttt commented 3 years ago

i powerwashed and it didnt ask password . the problem is wifi not working. please fix this.

asukumar10248 commented 3 years ago

press Ctrl+Alt+t, then type shell then sudo edit-grub-config. After that you should find “options=“ . Then type and make it “options=broadcom_wl”. Finally press Ctrl+O then press enter then Ctrl+X. then type sudo reboot.

ravindrank commented 3 years ago

Even I have the same issue.. I have added the options and it was working fine until few months ago. Over last few months, the wifi doesnt work any more. I'm sure lot of Broadcomm users have the same. The module loads fine and I can see the drivers loaded but no wifi accesspoints show up post scanning

How is this going to help? Asking because.. kernel version doesnt match..so those modules would never get loaded..

sebanc commented 3 years ago

The update did not work, there was a mandatory brunch update that you missed and now it won't let you update. You can confirm with "cat /etc/brunch_version" command that it is still the old one.

To fix it, install the "pv" package from chromebrew and try again the update: https://github.com/skycocker/chromebrew

ravindrank commented 3 years ago

Thanks... I was able to get pv using crew..

Brunch updated.

Now version shows 91 Rebooted and still dont see the wifi listing any SSIDs..

Anything else I should try? EDIT: I think you are right.Went thru the releases and I missed 88 (which is probably causing all these issues for me and others) Do you think install 88 and 89 (has some wifi regulatory updates) back to back will help?

sebanc commented 3 years ago

Could you attach a dmesg ? Run "dmesg > ~/Downloads/dmesg.txt" in crosh shell and attach dmesg.txt from your Downloads folder.

ravindrank commented 3 years ago

Here it is ... dmesg1.txt

Meanwhile ChromeOS build got updated and when I rebooted I can see I'm on 5.4 kernel.. was excited to see if somehow wifi worked.. no luck.. one more for you.. dmesg2.txt

Unfortunately the log seems pretty good (and different compared to other dmesg I had on issues with broadcom_wl driver), I don't really understand where the issue can come from...

Still no WiFi scan after loading the lib80211 module ?

The broadcom module name is just "wl", it looks correctly loaded and created the interfaces.

Unfortunately I am a bit lost here...

sebanc commented 3 years ago

Yes for clarity I renamed the module file to broadcom_wl.ko but the actual module name as recognized by the kernel is still "wl"

In other words broadcom_wl.ko file = wl module

ravindrank commented 3 years ago

I see... just for some fun.. I installed 88, 89, 90, 91 unstable in the order and checked everytime to see if there is a change.. same behaviour..

I will spend some time tommorrow comparing with my Ubuntu and see what I find..

one thing though.. I havent seen the below on Ubuntu..

@ravindrank Could you try to replace "modprobe mac80211" by "modprobe cfg80211" in the file /etc/init/broadcom_wl.conf ?

And also add "blacklist mac80211" in /etc/modprobe.d/broadcom_wl.conf ?

ravindrank commented 3 years ago

Thank you @sebanc Tried this and the module list looks fine..No change though. No listing of the wifi SSIds.. Tried to connect to known networks just be sure and got out of range..

press Ctrl+Alt+t, then type shell then sudo edit-grub-config. After that you should find “options=“ . Then type and make it “options=broadcom_wl”. Finally press Ctrl+O then press enter then Ctrl+X. then type sudo reboot.

sir can you post step by step screenshot for this. thank you very much

just copy paste in terminal

I'm facing the same issue on my vaio with BCM943142HM.

go to ctrl + alt + t {terminal} and type shell and copy all below and paste sudo su mount -o remount, rw / sudo echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist b43legacy" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf sudo echo "wl" >> /etc/modules sudo touch /etc/modprobe.d/wl.conf sudo echo "alias wlan0 wl" >> /etc/modprobe.d/wl.conf cd /lib/modules/3.4.0/kernel/drivers/net/wireless/ wget http://chromium.arnoldthebat.co.uk/files/fw/lib/modules/3.4.0/kernel/drivers/net/wireless/wl.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/cfg80211.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_ccmp.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_tkip.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_wep.ko sudo insmod /lib/modules/3.4.0/kernel/drivers/net/wireless/wl.ko sudo depmod -a

Doesen't seem to work.

Even I have the same issue.. I have added the options and it was working fine until few months ago. Over last few months, the wifi doesnt work any more. I'm sure lot of Broadcomm users have the same. The module loads fine and I can see the drivers loaded but no wifi accesspoints show up post scanning

go to ctrl + alt + t {terminal} and type shell and copy all below and paste sudo su mount -o remount, rw / sudo echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist b43legacy" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf sudo echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf sudo echo "wl" >> /etc/modules sudo touch /etc/modprobe.d/wl.conf sudo echo "alias wlan0 wl" >> /etc/modprobe.d/wl.conf cd /lib/modules/3.4.0/kernel/drivers/net/wireless/ wget http://chromium.arnoldthebat.co.uk/files/fw/lib/modules/3.4.0/kernel/drivers/net/wireless/wl.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/cfg80211.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_ccmp.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_tkip.ko sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_wep.ko sudo insmod /lib/modules/3.4.0/kernel/drivers/net/wireless/wl.ko sudo depmod -a

How is this going to help? Asking because.. kernel version doesnt match..so those modules would never get loaded..
