Just got the 2.6/16/512 and have noted that the wifi reception could be stronger. In notebook check review they claimed that on their n router they were getting weaker signal than 2 other test machines. One floor above the AP I am getting between 5 megabit and dropped signal, my 2009 thinkpad gets 20-50 in same area and never drops. I also have a very strange experience with AC. It always connects at n unless I put it in same room with AC AP. Then it connected at 25! Should be able to connect at 500+.
