I just bought a ipad 3.
I have a 4-5 year old HP Mini.
The signal strength on the ipad is less than the cheap HP! I have read many posts about this being a common problem early in 2012. Has it been addressed? It makes no difference if I take the cover off or leave it on. The difference is so significant that I cannot use the ipad in the livinroom. I have to bee in the bedroom, about 12-15 feet closer to wireless router. I am disappointed.
