how can i connect my digisol wiless broadband router with usb port model BG4100NU with my i-ball 21.0MP-58 dongle directly or through ethernate cable of my pc
I have not used either of the devices you referenced, however, on most routers you have the ability to "add storage" through USB and share it inside and outside the network. Look-up a guide for your router. I can't help you a whole lot without seeing the router interface.
