Now , user can follow few things to make a proper internet connection.
From the router's web page, disable the "Universal Plug and Play "option. This can be done by going at Administration, then go to Management and disable the UPnP and Save settings.
Try changing the channel of the Linksys router. Go to the "Wireless "then "Basic wireless Settings ". Try changing the channel to 1, 6. 11 and Save settings. These are non overlapping channels.
Try to change the MTU( Maximum Transmission Unit ). Go to Setup then Basic Setup. Now change the MTU from Manual to any number. User should be careful while entering the number because if it will be very high then there are chances of improper connection and packet loss.
