hi I have had a di624 dlink wireless router for couple of years. in the last 3 months the signal strength on the router has decreased. I cannot use it productively today. i have had the same wireless cards on the laptop and desktop in the last 2 years. now even if i keep my laptop 5 feet from router, i get low signal and no proper connectiity. i have upgraded my firm ware too and get no better results.
help.
