I end up getting this below. I connect to my AP on 2 GHz and then give up as it stalls there as I try to fire up gmail (while my home page did load), when I give up I move to 5 GHz and I get similar stalls and now am just on Ethernet. Behind the scenes I just had Pandora on Ethernet downloading music as usual and my Galaxy S 4G phone uploading video/pictures to G+ automatically. I reset my AP two days ago, same as the broadband modem device.
