My iphone 4s can't connect on mHotspot?

I downloaded mHotspot on my laptop, which is only connected with a cable because our Wi-Fi can't reach my room. Someone told me about mHotspot and I did every step to make it work. But my iphone is still unable to connect. I did everything like turn the firewall off. Still not working. I shared it already in my local connection properties. But still unable to connect. Can anyone help me please.

I suggest that you check your router first. What type or router are you using? Is it a modem router in one?
1. Make sure the power light on your router is on. Same as your modem.
2. DSL light on the modem is stable and green
3. Internet light on the modem is on and green, it might be blinking, that is normal.
4. On your router, make sure that the link light is on too.

If you are having a problem with your iphone 3gs that keeps restarting then i suggest to reset it by following this steps. Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
