The store's wifi was not shown at all on the Acer. I called a salesman over and he manually set the store wifi into the Acer and then the browser and all started working. So then I started wondering why the Asus would show ten available connections - most with strong signals - and the Acer only show one that it could not connect to because it was not strong enough.
The store's wifi was not broadcasting its SSID. Once the salesman keyed it in, then the Asus and the Acer can see all the same access points.
Some places set up their house network like this so that people in the store don't use their devices to surf on the store's bandwidth. Best Buy is known for this in most of their stores. The last thing they want is you shopping for a better price using their network.
Any hacker worth his salt will blow right by that trick in about 3 minutes of standing outside the store. Hiding SSIDs is no real security at all.
So don't blame the Acer.
