[amontejj]

My new Vaio VPCM11M1E(windows7) wireless conection was working perfectly well, but now it is not.

It all seems to be ok but,it doesn´t find any wireless conection.

Anybody had this problem?
thanks

Hi amontejj and welcome.

What have you tried?
Have you checked that the physical wireless switch on the front of your Vaio is on and the wireless light illuminated?
Have you checked in Vaio Smart Network that only the 2.4GHz Wireless LAN is selected?
Is your Vaio up to date with updatesfrom Vaio Update?
In Device Manager, does it show that your Wireless Network Adapter is correctly installed and working properly?
