The wireless standard has been processed for a particular purpose. It is enhance with incorporating of modern technologies. There are too many wireless network standards and have to check network address in assigned range.
If it shows the exclamation point it is difficult to choose particular wireless system in a Wi-Fi . A wireless home network has access without permission. The firewalls which is used to accept or reject access.
The connection have to check various standard platform which allow client to access without disquieting about connectivity in their own network in home.
Changeability in network connection
In home network client use a network and have experience difference of router distance, congested network and base station connection is wrong where rate of recurrence bands and numerous wireless system may coexist.
It is very difficult to represent an erratic broadband connection to low deployment rate the possibility of coexistence in wireless system has low. The propagation of wireless system increased which will increase the rate of intrusion within same or different system.
Intrusion actually degrades the system throughput in large population such as railway station or common place. Use of 5GHz is a successful solution for diminish the authority of intrusion become most popular wireless system use 2.4GHz band. And the channel 149 use to explore where networks use around the home.
Wi-Fi networks are not find out properly
In a home network people use to communicate with devices and numerous devices will increase considerably. The procedure of setting is very complex because users differ in home wireless network .
It is necessary to create a protocol or mechanism that user does not need to implement any procedure settings in home network. In wireless system the procedure has to be followed for both settings and certificate in future to be simplified.
The first thing have to check whether device is airplane mode which able to not connecting Wi-Fi. The devices which connect to 2.4 GHz band .
