There appears to be quite a few people having problems with wifi on the Transformer Prime. Unfortunately I am one of them. I waited almost a month for the Prime which is my first tablet and now it looks like I may have to return it. Wifi works fine as long as I'm close to my router. My router is in my basement office. On the first floor of my home the wifi connection speed drops significantly from the basement level. On my second floor bedroom level I cannot connect at all. I have a 5 year old laptop, Nook e-reader and a HTC smartphone, my wife has a Kindle e-reader and a Kindle Fire tablet. All of those devices can connect to the router without any problems anywhere in the house. I am so disappointed. I like everything else about the Prime but this wifi situation is unacceptable.
