A new WiFi card can be installed in a desktop computer fairly easily, as it goes in a PCI Express slot, but if the signal from the modem/router isn't good enough at the computer's location, a new WiFi card probably wouldn't help. The WiFi cards themselves aren't all that expensive.
I would first check your WiFi signal strength at the location of the deskop. You can use the HughesNet Mobile app, which works on your phone, and which has a "WiFi Gauge", or any other mobile app that you like that can test WiFi signal strength. It's possible that it's a range issue, and a new WiFi card may not actually do the trick if this is the case.
If it is a range issue, HughesNet does have a WiFi Booster that works with the HT2000W modem, or you can even use a 3rd party WiFi router that gives better WiFi range than the HT2000W's.
Sometimes the makeup of a house can affect a signal where you wouldn't normally think it would, so it would definitely be a good idea to test that WiFi signal strength at the location of your desktop.
Edit: Sorry, I should have given the link to the HughesNet Mobile App. Android and Apple.
