Description of problem:

I installed RM2012.EE on my Lenovo T420S notebook and have a problem with intermittent dropouts of Wi-Fi connection. In can be several times in minute, or 1 time in 2 hours (notebook do not lose connection most of time!) and every time it is very annoying. 

I can't say for sure how to reproduce this bug  even if you install ROSA on computer with the same wireless adapter, but it is reproducible 100%.

And lspcidrake -v. I connect to my network after doing:

sudo systemctl restart NetworkManager.service

Do you know - is there a chance that you have cisco wifi hardware providing the network ?
Comment 5 Denis Koryavov 2012-08-21 00:55:38 MSD
In office - yes. In home I have ASUS RT-G32.

Here is the trimmed log. As far as I can see, we have some problems with IPv6. So, I set this setting to 'Ignore' for my connection. I will write - it will help or not.

Many users made their complaints that the problem not only for WiFi - also for the ethernet.

What about disable cups sharing and avahi?

We didn't get any similar bug reports for Fresh and RED X2. Let's assume that everything is ok now. Feel free to reopen if you are able to reproduce the issue.
