I've had to do it (install a missing GUI front-end for NetworkManager) myself a few times in the past. Like everything else, it's not difficult when you know how.
If the lack of connectivity turns out to be something else (there are many possibilities, unfortunately), make sure to post as much information as possible here to enable readers to help. See, for example, the thread
Howto Gather Log Files Easily - Help Us to Help You.
As the bare minimum, to make it easier to diagnose, you'd need to post:
1. Name of the manufacturer & the model of laptop.
2. The output of the following commands (issued as root user in a Konsole/Terminal window):
- Code: Select all
uname -a
lspci
lsusb
lsmod
ifconfig
rc-status
equo search network
equo search nm-applet
cat /var/log/messages | grep -E -i --text 'error|network'
3. If wired networking is working and you are trying to get wireless networking working, also the output of the following commands (issued as root user in a Konsole/Terminal window):
- Code: Select all
iwconfig
dmesg | grep -E -i 'error|wireless|firmware'
equo install rfkill
rfkill list
iwlist wlan0 scanning # Replace wlan0 with your interface, if different
If you don't have either wired or wireless access from the laptop, you can redirect the output of the above-mentioned commands to a text file and copy them to a pen drive. E.g. lspci > lspci.txt
