(SOLVED) missing wifi

I am new to Zorin OS 9 and so far it is the best OS I have used. Computer is Dell Latitude E6400 with the same wireless card and chipset as in this thread. The computer has been upgraded with SSD and 8GEG RAM.
Only one thing, like madviegar in the post last year. I could not get my laptop to see my wireless card / connections. I followed the instructions posted and after entering the commands in terminal mode, up poped the wireless networks in my area. I was able to log into my wireless, type in the password and it worked. I removed the ethernet wired connection and it still worked. Great!

Then I shut down my computer and when I rebooted, the wireless was gone. I plugged the ethernet cable in, and it reconneccted to the network through the cable. But the wireless was gone. I opened terminal mode again, retyped the commands and the wireless was working again.

I tried restarting the computer the cable connected (wireless gone) reentered the commands again, it worked again.

But every time I restart the computer, with or without the cable, the wireless is gone until I reenter the commands.

Why, and what can I do to keep it configured to let the wireless always work.

Thanks

Joe

Hi,

did you add the network in the network manager and save it?:

It might also be a bug?:

You might want to wait for Madvinegar to pop along with more advice as I split this post from a thread you posted in, see also:

Type the commands again to get wifi working and then post back here results of the two following commands:

lspci -nnk | grep -iA2 net
sudo lshw -c network

I will then tell you what to do to get the wifi to start automatically.

madvinegar, thank you for your help. Joe

The wireless networks were visible, then I rebooted and they were gone, except when I selected edit the connection, my wireless connection was listed.

this is what happened when I entered the commands;

one more thing. as the wireless was connected (with the Ethernet still plugged in) I turned the hardware switch for the wireless off, waited a fer seconds and turned it back on. This time when I tried to look at the connections, the connection icon would not expand. I pulled the cable off and confirmed that the wireless was not connected. Plugged the cable back in the wireless did not connect. I went into terminal mode, re entered the script, but the wireless would not connect, and the connection icon would not expand.
only after rebooting and reentering the script could I get the wireless to work.
Joe

Open terminal and run the following command:

echo 'wl' | sudo tee -a /etc/modules

Unplug the ethernet cable and reboot.

Thank you very much madvinegar!
Worked perfectly!

Joe

Glad I helped my friend.
