Never mind, Mr Wizard. FYI here is the print out from the AI supporter. I only needed to get to step 2. Also, remember that your support with BCM4312 was the start of the road to victory. Kindest regards and thanks. JM1
Step-by-Step Guide to Fixing Wi-Fi on HP Mini 1100 (Linux)
Problem: Wi-Fi shows
NO-CARRIER,
Hard Blocked, or fails to connect with errors like
"Not authorized to control networking".
1. Check Wi-Fi Interface Status
bash
ip a
- Look for
wlan0 or similar. If missing, the driver isn’t loaded.
2. Unblock Wi-Fi (If Hard/Soft Blocked)
bash
rfkill list # Check blocks
sudo rfkill unblock all # Unblock all
3. Verify Driver and Firmware
bash
lspci -k | grep -A 3 -i network # Identify Wi-Fi chipset
sudo dmesg | grep -i firmware # Check for errors
- Reinstall drivers/firmware (e.g., for Intel Wi-Fi):
bash
- sudo apt install --reinstall iwlwifi firmware-iwlwifi # Debian/Ubuntu
sudo modprobe -r iwlwifi && sudo modprobe iwlwifi # Reload driver
4. Fix Permission Issues
Temporary Fix (Use sudo)
bash
sudo nmcli device wifi connect "SSID" password "PASSWORD"
Permanent Fix:
- Add user to
netdev group:
bash
- sudo usermod -aG netdev $USER
- Update Polkit rules:
bash
sudo nano /etc/polkit-1/localauthority/50-local.d/50-network-manager.pkla
Paste:
ini
- [NetworkManager Permissions]
Identity=unix-group:netdev
Action=org.freedesktop.NetworkManager.*
ResultAny=yes
ResultInactive=yes
ResultActive=yes
- sudo systemctl restart polkit NetworkManager
5. Connect to Wi-Fi
bash
nmcli device wifi list # List networks
nmcli device wifi connect "SSID" password "PASSWORD"
- Still failing? Use
--ask for password input:
bash
- nmcli --ask device wifi connect "SSID"
6. Disable Power Saving
bash
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/*
sudo systemctl restart NetworkManager
7. Blacklist Conflicting Modules (HP Laptops)
bash
echo "blacklist hp-wmi" | sudo tee /etc/modprobe.d/hp-wmi.conf
sudo reboot
8. Test Hardware (Last Resort)
- Boot a Live USB (e.g., Ubuntu). If Wi-Fi works:
- Reinstall your OS or drivers.
- If not, try a USB Wi-Fi adapter.
