wifi connection- "Unable to connect"
Hi my iphone 3g-8gb black had a problem.
Before i can enjoy our house' wifi signal but now, i cannot connect anymore. I never dropped or any incident before it happened. But i can remember turning the wifi router once (saving electricity purposes. And then after turning it on again, i can't receive any wifi signal anymore. I tried to reset the wifi router thrice. And all of my family's laptop can receive the wifi signal after resetting the wifi router thrice, but my iphone 3g is not receiving it anymore. It see's the router but it keeps on alerting "UNABLE TO JOIN NETWORK"
I also tried to go
1. into Settings -> General -> Reset - then tap on Reset Network Settings
2. jailbreak my iphone
3. and before resetting my wifi router, i tried clicking the "forget this network"
***all of this didn't help at all, can somebody help me?

iphone details: iphone 8gb- black
Software version: 4.2.1 (8C148)
Is this a good question?
