no internet after update

Pedroski · 05-29-2012, 06:22 PM

Two days ago an update wiped out my internet. How can I reconnect?

I use Fed. 16. An update installed the latest kernel, and network manager. On reboot, I noticed that the networkmanager icon was missing. I went to System settings, Network. That says 'the system network services are not compatible with this version'

So no internet with Fed 16.

How can I reverse this, given I now have no internet???

I tried NetworkManager up I get no error message, but no internet.
I downloaded NetworkManager.rpm, a version from 2011, but it won't install, it says 'failed to install, no transaction' I don't know what that means!
I also tried booting an earlier kernel, but no joy.
I can download anything using Ubuntu. Any tips out there??

Often, when Network Manager fails for me, a manual network start will work.

Code:

Something like the following:
service NetworkManager stop
service network restart
iwconfig wlan0 essid=<MyESSID>
ifup wlan0

Or, using Ubuntu, head on over to http://koji.fedoraproject.org, download the older NetworkManager rpms that worked for you, then install them on your F16 system

Code:

rpm -Uvh --oldpackage <rpm names go here>
