I am using Acer aspire 5749Z laptop with windows 7, 32 for four years. I have installed Qualcomm Atheros AR5B125 Wireless network adapter (downloaded from Acer official website for windows 7 32 bit operating system). I am trying to connect to wireless network but after connecting, a window appear with a message "Windows was unable to connect to the network." I run windows troubleshooting and the resulting window showed a message "Problem with network adapter or access point". I am using the same wireless network for my samsung and micromax android phones and they are working well with the same wirless network. Sometime wireless network connects but after few minutes it disconnects. Also the wireless network disconnects if my router is in one room and I use the laptop from another room. After searching solutions for this problem on Acer support website and Microsoft support I uninstalled the wireless network adapter and reinstalled the driver but the problem is still persist. I format my laptop and again installed window 7 and wireless network adapter for many times but the problem remain same. I tried the solution given below but it didn't worked too.
