Ok here's a strange one. My desire has been connecting to my home Wi Fi without any problems. Last night I couldn't get it to connect. I checked my computer was still connecting and everything is ok. Assumed from this that it was a problem with my Desire. However, here's the strange thing. I have a Nokia 5800 which can no longer connect and a Kindle which can no longer connect. So to sum up, out of 4 wireless devices, one will connect and three won't. Any ideas?
