I plan to create a wifi hotspot with My WIFI Router software,because I have no wireless router.I want to know if there is any difference?And could I get better wifi service with wireless router?

For those that are unable to get the Hotspot working no matter what they do.....
The Play Store has an app called Wifi Tether Router by Fabio Grasso. It works just fine and it's free if I'm not mistaken. I use it all the time for the last year or so. Best alternative. Give it a try.....
