I have the titled router, not through VM from Amazon. It has worked fine for a couple of years. I rarely use the wireless feature but turn on now and again. Tiday when turned on it lit up and said on but my netbook, phone and DS couldn't find it. I factory reset the router and it worked fine, wireless to all three devices. Hour later all off again and unable to connect wireless, again reset router and fine again.

Any ideas what causing this issue?

Thanks
