Latency?
A relative used to have satellite internet. Throughput was great, but the 2000ms *minimum* ping time was a bit of a problem - type in a web address, wait 2 seconds, the html file loads, wait 2 seconds, then the CSS and image files start loading...
The eventual solution was an 80-foot-high tower in the back yard, to establish line-of-sight over the next hill for "wireless" access.
