This little unit can be used as a WiFi Range Extender, an Access Point , or a Wireless Router.
I am not particularly technically minded, however, I do use the Internet. A lot. And our wifi here is poor to put it mildly. It is not too bad when you are close to the modem most of the time but pretty poor through the rest of the house.
I know this unit does much more but my need is simply to extend the range of my wifi so I can access it elsewhere in the house.
As I said, I am not technically minded, but my husband had this sorted in seconds after a brief look at the instructions. So far there certainly does seem to be an improvement.
