Several issues are at work here.
First, trying to get a good signal when the receiving device is below the radio is a problem. For details, do a basic search on wireless propagation. Second, the farther you are from the transmitting radio (i.e., the router), the poorer the signal. Simple propagation physics.
Third, you haven't indicated your speed tier and it's possible that increasing your Internet speed may help. Fourth, see if you can run Ethernet (or even coax) to the basement area. This will allow either a direct connection or a second router with wireless capability.
Based on your statement of the problem, the above routes appear to give the best chance to improve your situation.
