I have had my EA6400 for probably a year and a half. In the last 6 month I have noticed that all my wireless devices will lose connectivity and receive "Unable to obtain IP address". I work for Charter Communications and I have investigated in our systems that my Modem is a rockstar and never loses connectivity.
The "easy" fix for this is to power cycle the wireless router. I find this troubling becuase I can still see my Wifi broadcasting good signal inside of my WiFi Analyzer application.
Thoughts?
