I have a DGL-4500 with firmware 1.15, WEP security, everything works great. But I got a new Dell E6400 laptop with Intel 5100 AGN wireless card. That new laptop will connect for a while and then randomly drop the connection. All of my other equipment still works fine (xbox, wii, other laptops, macbook, etc). I was told that the new wireless cards are more "sensitive". Anyone else having problems with new wireless hardware?
