Since upgrading from Ubuntu 10.04 to 12.04 on my ACER Aspire One D270 I have problems with WIFI-connectivity. I was planning now to upgrade to Ubuntu 14.04 hoping to solve this problem. On reading the last bunch of questions posted here I find quite a few regarding problems which arose after installing Ubunto 14.04. Would like to get opinions - is it worth upgrading yet or are to many problems to be expected?
