problems with wpa/wpa enterprise wifi

[rob]

Hi all
I am having some issues with connecting to works wifi - which uses a novell username and password in wpa2 encryption.
all was working fine until the start of last week.
I get a connection failed message and the the mode is reset to none each time I look at the configuration.
There was an issue with all other wifi connections but install and then removed netwokmanager and this seemed have have cleared the problem.

what seems to be happening here? thanks

[doktor5000]

Your different network devices are listed there, along with their PCI device identifiers. And if for one given device a MAC adress changes (network adapters in virtual machines, or hardware replacement) this device will get a new alias/label, for example look at the entries for eth0 and eth1, which both use the same driver, but use totally different MAC adresses.

I don't know which adapter you want to use, or what is expected here and what is not.
To clean them up, you take a backup of the file, and delete all entries below the header, so only thing left is:

Still no luck with what? How did you test it and what output/errors did you receive?

I attempted to connect to the wifi using the gui and still got the connection error - checked the /etc/udev/rules.d/70-persistent-net.rules file and got the above .
will investigate if got time today as its very busy at end of term.
Thanks for your help

as an update - eneded up reloading , couldn't see what was stopping the connection.
all was good , but on both laptop and pc this morning - no boot up.
