Hi I have a problem with conecting to my wifi. I see my wifi, but when i am trying to connect to it- i write the password and the password-window pop up again like the password is wrong (but it is good, on another laptop's ubuntu and on this laptop's windows everything is running just ok)

info:

cat /proc/version

Linux version 3.16.4-200.fc20.x86_64 (mockbuild@bkernel02.phx2.fedoraproject.org) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-7) (GCC) ) #1 SMP Mon Oct 6 12:57:00 UTC 2014

Have you tried to connect after disabling the WPS on your router.

I've checked settings on another laptop's ubuntu that can easily connect- it has set another MAC for this connection. But I cannot change it (in gui for sure). Maybe it is sth with the fact that MACs are the same? I've just upgraded to 1.16.6 kernel.

Can you please add the corresponding output of /var/log/messages or journalctl, respectively?

it works now, wow, thx. But there is no "workaround" this? I set same MAC to be able to connect to internet (i'll talk to admin to add my second mac, but this can take time so i found changing MAC a faster way)

A MAC address is intended to be a unique identifier; setting your router and laptop to have the same MAC breaks this. The first thing you need to do is undo that, so that the two machines can tell each other apart.

Ok, that help, but to be complete ill say what i also did. previously i've just copied my mac and set the same on the ethernet what cosed the problem. But it is even explained in my router's help that this procedure is sometimes usefull, but i did it in a bad way. Ive copied the clone instead of use built in script to do thiss. Now i've tried to use a button in routers setting "copy mac". I dont know how it works but it does work ( I see another mac while connecting to router but i do have connection to internet)

ahhh, problem is not solved. I tought it'll work, but it worked for one boot time. It happend previously (worked for some time). Now the same thing happens- can't access to the wifi (with cloned MAC and normal MAC)
