I have an Inspiron 15 3000 Series. When I first bought it, my condo complex installed AT&T wireless with speed of approx. 100 Mg., which I got on this computer.
However, in my other residence, with Verizon Fios internet, I get 9.45Mbps Download Speed and 22.66 Mbps Upload Speed.
To compare, my IPhone gets 41.16 Mpbs Download Speed and 55.06 mbps Upload speed.
My question is why is my computer wifi so slow?
