HI Barb,
Have been travelling so delay in response.
OK... I connected to the 5Ghz. went to speedtest.net. Page loaded reasonably ok... but it took 45 seconds before I got the ping test back. (which was then 10ms). and I got a download test error after 3minutes of waiting on the actual test. At which stage when I chose "try again" it said you're not connected to a network.
BTW: on my desktop @ home I get an instant ping and 60Mb/s download. My Dell latitude on the 5Ghz gets instant ping and a 36Mb/s download.
Therefore problem is not user, problem is not 5Ghz network, problem is not ISP.
On the 2Ghz band I get ping 15ms and download 1.2mbs
