Help me Please! 8900-- wifi "no connections found"
 

Good day mates! please help me with my 8900 problem,i have couple of bb smartphones,i have a 9700 and 8900,
I have no issues or problems with my 9700
but with my 8900,I can't seem to connect thru wifi,it usually tells me No connections found!
eventhough i both tried them on the same time and same place,my bold 9700 and my laptop can search the connection and as the same time they can connect too but my 8900 cannot even search that connection.
tried pulling out the battery,also installed latest os 5.I also enabled mobile network options.
please help me as I am getting paranoid already.THanks! have a great day!
