I am using an Acer aspire laptop, it is running with windows vista OS. Other specification of my machine are like Intel core 2 duo processor, 2GB RAM, 320 GB hard drive, along with this NVIDIA GEForce graphics driver. Along with this the machine is compatible with wireless network connectivity. The machine was working fine till the last few days back, but from two days back it starts a problem with the wireless network service, which disconnects frequently when it is connected. Though there is no issue with the connectivity, it connects easily, then why this problem occurring canít understand. Is there any one having any information or solution for this type of problem? Any input will be appreciated greatly.
