I have upgrading to LM 14 Cinnamon (and am loving it ); however, I have encountered an issue with my wireless driver. Its speed has been a fraction of what it was prior to my upgrade (btw I did a clean install). I have also noticed that the wireless crashes every 30 minutes or so; however, I can correct this by turning my wireless card off/on.
I do not believe that this is a networking issue because while my Acer Aspire One AO722 was having problems with LM 14's default driver, other devices on my LAN worked properly.
I have Googled for solutions but have not found any. On another form, someone asked for the output of "lspci -vnn | grep -a4 -i net" so here it is:
