From a HughesNet user. One single test is not enough to approach HughesNet. Try several tests, several times a day and several days apart. We had the same problem and we put the info out on the HughesNet community board. After a few days, and after reviewing the tests my speeds suddenly jumped to about 20mbs download.
The problem your daughter is having with WiFi is not related to HughesNet unless they supplied the router. I have an ASUS router and can receive several hundred feet from the router.
The router is attached to the H9000 modem supplied from HughesNet.
