I have just moved house.
At my old address I had a Dlink 502T running in conjunction with a Linksys WRT150N wireless router and had no problems at all for over 18 months.
When I moved to the new address everything worked fine for a couple of hours.
However when I got up the next morning the router wouldn't connect to my laptop and I have had constant problems since.
I have tried doing a full reset on the router with no luck.
I know the issue isn't with the Dlink modem or the line in the house as I can plug directly into the modem and have no problems.
I guess it's possible the router has died or in the process of doing so but it seems a coincidence that it has occurred just after moving to a new address.
My laptop is only a few months old and does not appear to be having any problems other than connecting to the router.
Any suggestions?
