I'm using a Asus eeePC1000HE netbook with UNR. Just upgraded to 10.10 Maverick from 10.04. Before upgrading, my wifi worked fine. On upgrade I found that wifi worked fine until I put the PC into suspend mode. On resuming from suspend, network manager failed to find the wifi device (Ralink RT2860), and wnt into an infinite wifi scan.
I tried the following solutions, none of which worked (all sourced via Google):
* replacing the released drivers with ndiswrapper and xxx driver
* replacing network-manager with wicd
* upgrading to latest kernel
* blacklisting rt drivers
Finally, I found a solution from elsewhere in these forums that fixed it:
Create a file called 'config' in /etc/pm/config.d, and insert in it the following line:
(replace ndiswrapper with whatever your driver name is. Use lspci -v)
Since doing this, the wifi resumes from suspend. Only minor problem is that it takes about 5 secs.
Just thought I'd post this, as it was painful for me over 2 weeks.
