[746]

hi ! i have an asus x55c-sxo78d laptop . i have difficulty in using the keyboard and mouse ,so i bought a combo of wired usb keyboard+mouse. i also have a usb modem for internet connection . when i plug in the usb modem , it is impossible to plug in any other device because it is very big. so, i bought a cheap usb hub called tricom usb hub which has four ports. after a week three of the ports stopped working and the other one does not have enough speed.what can i do? i don't want to buy anything new because i have spent all my money. how can i fix the hub?this is the picture of the hub below. can i make a wireless usb hub?
I DONT HAVE ANY WIFI ADAPTERS OR BLUETOOTH DONGLES OR SUCH THINGS.
can i make the modem which is dial-up&vpn to plug and play?
