Currently my phone doesn't connect to WiFi connection, it always on and off everytime I open my WiFi connection.

Solution for the i5801:


Go to Settings → Wireless and Network → WiFi
Use the menu button to open the Advanced option
Click on Use static IP
You will see IP address, Gateway, Netmask, DNS1, DNS2. Fill all these things and to see their value:

left click on signal strength (left or right to battery or sound sign)
right click on your network to which you connected
you should see status; click on this
now a page is open (wireless network connection status); here click on details
now you should see IPv4 (IP address), IPv4 default gateway (gateway), IPv4 subnet mask (for netmask), IPv4 DNS servers (DNS1, DNS2)

Save all these setting by clicking on menu then save.


If this does not work check this also:


open 192.168.1.1
open Wireless → Security check (network authentication WPA personal auto)
after that your password
then next [WPA group rekey interval 3600 (in my case this is the problem in my modem here is 4 so i remove it and type 3600)]
after this (wpa/wapi encryption tkip+aes)
then save this setting.
