[yohankay]

hey,

guys i have a wifi issue hope you can help me on this.

i rooted my huawei sonic and check several custom roms on it. they all worked fine but, all of the sudden, my phone got this problem.
wifi of the phone connects to the home wifi network. (which is perfectly work on my laptop and was to the phone).

my problem is i cant connect to the internet though my wifi but it perfectly connect to the phone and even shows the signal strength also.

i check the router, it shows that this devise has also an IP address which is assigned through the router.
