Please Help !! I have had a samsung galaxy s2 for a few months now and it has always connected to my home wifi totally fine but the last week or so anytime I try to connect to my wifi it will find the device but when I type my password in the "connect" button is grey and will not allow me to select ...i can connect wifi at work so ruled out the phone and i can connect other mobiles/laptops to my home wifi so though that ruled out my router too! Would be veryyyy greatful if someone could help me x
