Windows 7: Windows 7 Wireless connectivity problems

OS :- windows 7
Problems found on HP PAVILION DV3515 , HP PRESARIO CQ61

• Unable to connect wireless if there is more available wireless connections are detected
• Wireless disconnecting if any new wireless range has detected

Actions Taken :- Drivers and OS update could not resolve the problem
( Could not found any problems with Routers , it only happens if a new connection detected into the wifi range )



Please advise me how to solve this problem ..

Set your wireless connection that you want to use as connect automatically and the others manually
