BT Voyager help please

My son has a Voyager 1040 (he has had it for about 6 months) and for some
reason we are suddenly not picking any signal up from the router. It has
been working fine up to now. The router is a 1800HG and seems to be
working fine and I have a good signal on my laptop. We have checked the pci
in the device manager and reinstalled the software. Everything seems to be
fine, it just isn't picking up any signal from the router. Can anyone help?

Thanks
Jill
