I am using ubuntu 12.10 on an hp dm4-2191us via wubi with the Realtek 8188ce wifi adapter. Everything works very well with the exception of the wifi. I have used wicd and it didn't worked at all so i went back to Network Manager with variable success.
It works for 30 min - 2 min before i have to reconnect to get it to work again. I would really like to use Ubuntu (it is a better platform in my opinion) but no wifi could really be a deal breaker.
