WiFi Tethering Probelm

[hishshu]

I have bought an Xperia Acro S about one month ago.

when I tried to use my phone mobile network in my laptop by enabling portable Wi-Fi hotspot, it only activated for seconds then go inactive.

I'd like to know where the problem is!!!!!

So you mean that the Wi-Fi hotspot feature disable itself so you have to enable it manually again?

If so I suggest that you try to reinstall the phone software using SUS.
