I've been having trouble with my internet speeds thru WiFi. What I just found out is that the cause is the BookArc that my MBA sits in. Sitting in the BookArc I was only getting 5-9mbps. Just lifting it slightly out of the BookArc increases it to 15-18mbps. I have the 25mbps plan but the router is a few rooms away. I tried this over and over and sure enough, it's the BookArc. Does anyone else have this problem? Do I really have to throw away a $40 product?
