zorin os9 on dell latitude d630 - can't use Wi-Fi

Need help. I don't know my way around pc. Here are the details of my laptop:

Only zorin os 9 is installed
Amount of available Memory (RAM) - 2 gig
Hard Drive partitioning - only 1 partition

Graphics card make and model, or Graphics chipset in respect of Notebooks - not sure

wireless Dongle or PCI Card, or Wireless chipset check below

Whether you ran Zorin Live first to check it worked before installing - I'm making a backup laptop. Just installed straight

___

Here's what I did. I need Wi-Fi to do work and download stuff. N I need to switch to this machine fast.

Just until madvinegar sorts you out can you report what:

Code:

sudo ifconfig -a

comes back with.

Please DON'T post the output as this will reveal your MAC Codes - do you get 'eth0' and 'eth1' or 'eth0 and 'wlan0' or 'lo'?

There is a soft block in the bluetooth. Sometimes the BT and wireless are inter-connected so this may cause the problem.

What happens if yiu run the below commands:

sudo rfkill unblock all
sudo modprobe iwl3945

Hi madvinegar,

for:

sudo rfkill unblock all
sudo modprobe iwl3945

there's no result.

Hi Swarfendor437,

I got:


eth0

lo

wlan0

Hi madvinegar,

After I run the codes, do I need to type some code to check something? or does it just pop up?

Plug an ethernet cable to get internet, open terminal and run the following command

sudo apt-get install --reinstall linux-firmware

Wait 5-6 seconds and check if you can pick wireless networks. A reboot may be required.

The firmware for your card is already installed in the kernel. I don't know why it has not enabled your wireless but this is why we try to re-install it and see if it will "wake up" your wireless card.

Problem is, I only have 4g connection via my phone.

I tried to tether via usb cable using an old iPhone 3 but it didn't auto connect.

It's there anyway around it?

Tried using another phone to tether via usb. Manage to access Firefox.

I typed the command but got this message:

~$ sudo apt-get install --reinstall linux-firmware
Reading package lists... Done

Reinstallation of linux-firmware is not possible, it cannot be downloaded.
The following package was automatically installed and is no longer required:
localechooser-data
Use 'apt-get autoremove' to remove it.

you need to find some proper internet connection to download the package.

Hi, I've manage to get cable internet and typed the codes. Now I have Wi-Fi but sometimes it doesn't detect when I relogin.
It's it normal?

It should reconnect automatically after relogin or restart.

If not, run the following command in terminal:

echo 'b43' | sudo tee -a /etc/modules

Then restart or relogin to see if all is working ok.
