Red cross/Busy Blue circle sign on perfect working internet connection

Respected Sir,

HARDWARE- I have Win 7,Home Premium,64bit,Dell Inspiron 15R N5010.
My network adapters are: Realtek PCIe FE Family controller & DW1501 Wireless-N WLAN Half miniport adapter.
My ADSL modem + WIFI router is Netgear DGN2200v3 latest version of firmware v1.1.00.10_1.001.

PROBLEM- My network connection icon in task bar shows Red cross disconnected or revolving Blue Busy circle network on wired and wireless connection. But my internet connection works perfectly fine. Please suggest solution to enable network notification correctly. I will carry out every possible advise to enable correct network notification. Problem arise when I personally fiddled with router's security option like changing WPA2-PSK[AES] to WPA-PSK[TKIP] + WPA2-PSK[AES] and again back.

Right now is WPA-PSK[TKIP] + WPA2-PSK[AES]. I have connected my laptop to internet via LAN cable.

My Netgear DGN2200v3 provides WEP, WPA-PSK[TKIP], WPA2-PSK[AES], WPA-PSK[TKIP] + WPA2-PSK[AES], WPA/WPA2 Enterprise. Also please tell which type of network security option should I keep to avoid further conflict. So which should I choose?

During troubleshooting this problem I encounter new problem that, in sfc/scannow failed to repair few of the errors. Now I don't know any thing about this hidden problem, BUT I WANT TO KEEP MY COMPUTER PERFECT & WORKING WITH SOLVING ALL PROBLEMS FROM ROOT CAUSE.:confused:
