Help Huawei Ascend Y330 not connecting to home wifi

[suiko]

hi all

I wonder if anyone can help with this problem.

Used to connect fine to my wifi at home, but now it recognises the network, but does not connect. Sometimes it says there is an "authentication problem", but mostly it just shows as "saved, secured with WPA/WPA2". It says signal strength is "excellent". Hmmm...

I tried going out of range, pressing "forget" for this network, and then coming back in and reconnecting, but to no avail. Also tried rebooting the router.

Wifi is working with my laptop.

Thanks
