Hello Everyone, Recently I bought this mobile Samsung Grand Quattro (I-8552). There has been no issues as such but recently i have been facing issues with WI-FI Connectivity. I use a Wi-FI @ Home & it gets connected very easily. But when i use it @ my friend's residence, it says "Saved & Secured" but doesn't connect. The Credentials entered are completely right & no additional settings are required to configure as such. When i observe, The Wifi Icon at the top left shows a ? Symbol. Please Help !
