@MD60 sounds like a poor connection from the PC to the hub. Could be poor wifi signal level in the area near the PC or simply an old WiFi card. Use Ethernet cables if at all possible. Assuming it isnt bring a phone near the PC to see if that slows down in which case you msy need a WiFinbooster. Given USB WiFi dongles are quite cheap it maybe worth buying one of those as older PCs often have only basic wifi built-in.
