Data card Not detucting

None of the data cards are detucting in my USB 5mtrs Extension Cable but other than data cards its accepting everything i really need data card to be connected with extension bcoz for signal issues... and the sad thing is i am getting full signal only in my bathroom thats y i need to connect through extension....

A 5 meter cable ( approx 16 feet) is pretty long for the Wireless
freq involved ( 2.4GHz range ) signal attenuation may be high.

Try another USB to USB cable with superior low loss cable.
