Problems with internets (wifi)

greetings people…
i recently bought a laptop, and misteriously the lan port doesnt start, the driver for the lan gives a code 10 error wich means it isnt starting up correctly…
but thanksfully, the laptop has wifi integrated, so, i bought an USB wifi thingi so i could use that to plug it into a computer and broadcast a signal so i can connect with the laptop. but aparently it isnt working very well…i think is because it doesnt gives me a dns (forgot the rest of the name)

is there a way for me to fix this so i could get wifi to my laptop?:sigh:
