Hello all.. I am having an issue with my WAP54G v3.0... It has been working for yrs.. all of a sudden it stops responding to pings.. I then have to recycle the unit for it to start functioning again. After recycling the unit, it may work for hours or minutes or days before it stops responding again. It has stock firmware with the most recent FIRMWARE that is on Linksys website. Any help would be appreciated.
