why wifi range is weak on my mobile

[AC Question]

I have samsung galaxy s3 wifi is only connected when router is near but if far then not connected if connected internet is not working properly

Wifi does have a limited range, and the walls of your house will interfere with it.
What do you mean by "near" and "far"?

Welcome to Android Central! Try rebooting your router. Also, check to see if the wi-fi channel your router is using is really congested in your area. Read about it in this guide: http://forums.androidcentral.com/am...roubleshooting-wi-fi-connection-problems.html
